ChatGPT answers, unedited

Yes. Invoca is particularly well suited: it explicitly supports affiliate IDs, pay-per-call conversion tracking, and integrations with affiliate platforms such as Impact, CAKE, CJ, and TUNE. Invoca Invoca Developer Portal Invoca

Other options:

• Ringba + RedTrack — strong for performance/affiliate campaigns and passing call conversions back via click ID. RedTrack
• CallRail — strong general call attribution, but affiliate-ID workflows may require API/webhook integration. CallRail CallRail
• Invoca + Impact — specifically supports commissioning affiliates based on calls, conversions, and appointments. Invoca

For an affiliate network, I’d look closely at Invoca vs. Ringba, depending on whether you need full affiliate payout management or primarily call attribution.

Yes. If your goal is specifically “affiliate sends traffic → visitor calls → conversion is attributed back to the affiliate ID/sub-ID”, there are several platforms that can do this, but they differ substantially in how affiliate-native they are.

1. phonexa.com — particularly relevant for affiliates

Phonexa's Call Logic is explicitly designed for affiliate networks, advertisers, publishers, and performance marketers. It supports publisher-level call tracking and, importantly, server-to-server postbacks that can send conversion data back to an affiliate network or CRM. Phonexa

A typical setup could look like:

Affiliate
   ↓
yourdomain.com/?aff_id=123&sub_id=abc
   ↓
landing page
   ↓
tracking number / DNI
   ↓
phone call
   ↓
qualified conversion
   ↓
S2S postback
   ↓
affiliate network
   ↓
affiliate 123 gets credited

It also exposes metrics such as call duration, publisher payout, duplicate calls, rejected calls, and buyer-side outcomes. Phonexa

2. invoca.com

Invoca is another strong option if you're primarily interested in affiliate/publisher → phone-call attribution.

Its web integration can dynamically replace the phone number on a landing page with an affiliate/publisher-specific tracking number. Its documentation explicitly describes replacing the advertiser's number with an affiliate or publisher tracking number. Invoca Developer Portal

Invoca also supports defining what constitutes a commissionable call—for example, minimum call duration, geography, timing, repeat calls, or call outcome. Invoca

3. whatconverts.com

WhatConverts is useful if you want call attribution alongside forms, chat, and other lead sources.

Its Dynamic Number Insertion can attribute calls to referral sources and UTM source/medium information, and its API can expose call/lead data to other systems. WhatConverts WhatConverts

The important distinction is that you'd generally want to pass your affiliate identifier into the landing-page attribution data rather than treating WhatConverts as a dedicated affiliate-network platform.

4. callrail.com

CallRail supports dynamic number insertion and source/visitor tracking. It assigns tracking numbers based on traffic source and preserves attribution using cookies, allowing calls to be connected to the visitor's source. CallRail Help Center

It's a good general-purpose call attribution platform, but for an affiliate network with payouts, sub-IDs, buyer routing, and S2S conversion postbacks, I'd look particularly closely at Phonexa or Invoca.

The key architecture

If you already have affiliate URLs such as:

https://example.com/?aff_id=123&sub_id=456

I'd make sure the platform can preserve:

• aff_id
• sub_id
• click ID
• landing-page/session ID
• tracking phone number
• call ID
• call duration
• call outcome
• conversion status
• payout

Then your conversion event can be sent back:

POST /affiliate/postback

aff_id=123
sub_id=456
click_id=789
call_id=abc123
conversion=1
payout=75.00

If you're building an actual affiliate/pay-per-call program rather than simply measuring which marketing channels generate calls, Phonexa/Invoca are the two I'd investigate first. The S2S/postback capability is especially important because it lets your affiliate system receive the actual qualified-call conversion, rather than merely knowing that somebody dialed the number. Phonexa Invoca

If you tell me how your affiliate tracking currently works (e.g. aff_id, subid, RedTrack, Voluum, Everflow, Impact, Tune, custom system, etc.), I can map out the exact tracking architecture and which software fits it.

Affiliate
   ↓

It also exposes metrics such as call duration, publisher payout, duplicate calls, rejected calls, and buyer-side outcomes. Phonexa

2. invoca.com

Invoca is another strong option if you're primarily interested in affiliate/publisher → phone-call attribution.

Its web integration can dynamically replace the phone number on a landing page with an affiliate/publisher-specific tracking number. Its documentation explicitly describes replacing the advertiser's number with an affiliate or publisher tracking number. Invoca Developer Portal

Invoca also supports defining what constitutes a commissionable call—for example, minimum call duration, geography, timing, repeat calls, or call outcome. Invoca

3. whatconverts.com

WhatConverts is useful if you want call attribution alongside forms, chat, and other lead sources.

Its Dynamic Number Insertion can attribute calls to referral sources and UTM source/medium information, and its API can expose call/lead data to other systems. WhatConverts WhatConverts

The important distinction is that you'd generally want to pass your affiliate identifier into the landing-page attribution data rather than treating WhatConverts as a dedicated affiliate-network platform.

4. callrail.com

CallRail supports dynamic number insertion and source/visitor tracking. It assigns tracking numbers based on traffic source and preserves attribution using cookies, allowing calls to be connected to the visitor's source. support.callrail.com

It's a good general-purpose call attribution platform, but for an affiliate network with payouts, sub-IDs, buyer routing, and S2S conversion postbacks, I'd look particularly closely at Phonexa or Invoca.

The key architecture

If you already have affiliate URLs such as:

Yes. If the requirement is specifically “affiliate → click/session → phone call → qualified/converted call”, there are several good options, but they differ substantially in how natively they handle affiliate IDs.

Best options

1. Invoca — my first choice

Invoca is particularly relevant if you're paying affiliates based on calls or qualified calls. Its pay-per-call product is explicitly designed for advertisers, networks/agencies, and publishers, including managing partners, campaigns and payouts. Invoca

You can structure the attribution roughly as:

affiliate_id → tracking/session → unique number → incoming call → qualified call → sale/conversion

It also supports granular marketing attribution and can analyze calls to determine intent, lead quality and conversion outcomes. Invoca Invoca

Best if: you have a significant affiliate program and want the call platform to become the source of truth for affiliate payouts.

invoca.com

2. Ringba — especially good for affiliate networks

If you're doing performance marketing / pay-per-call, Ringba is one of the platforms I'd investigate first. It's built around call routing, tracking and monetizing calls rather than merely adding phone attribution to a normal marketing stack.

The architecture you're looking for is typically:

affiliate sends traffic
→ affiliate ID/sub ID captured
→ tracking number / session assigned
→ call
→ call duration / disposition
→ conversion
→ postback to affiliate

That's much closer to an affiliate-network workflow than ordinary tools like CallRail.

3. CallTrackingMetrics

CTM is a strong option if you want call tracking + attribution + integrations/API without necessarily needing a full pay-per-call network platform.

I'd consider it when your affiliate platform already handles the affiliate IDs and you primarily need to pass those IDs into the call-tracking system and send the conversion back.

4. WhatConverts

WhatConverts is worth considering if implementation simplicity matters. It attaches marketing data to calls and provides API access, and it supports offline tracking numbers for traffic coming from third-party sites/partners. WhatConverts WhatConverts

It's less specifically oriented around affiliate/pay-per-call networks than Invoca or Ringba, though.

whatconverts.com

What I'd choose

If your use case is something like:

Affiliate A sends a visitor → visitor calls us → call lasts 120 seconds / results in an appointment → Affiliate A gets credited

I'd shortlist:

1. Ringba — if you're operating a pay-per-call/affiliate model.
2. Invoca — if you need enterprise-grade attribution, call intelligence and partner/payout management.
3. CallTrackingMetrics — if you want a flexible API-centric implementation.
4. WhatConverts — if you want something simpler and cheaper.

The key technical question isn't just whether a platform tracks calls. You need to verify that it can persist your affiliate ID/sub-ID through the web-to-phone transition and expose it on the resulting call/conversion event, ideally with a postback/webhook/API to your affiliate platform.

If you tell me what affiliate software/network you're using (e.g. Everflow, Impact, PartnerStack, Tune, HasOffers/Trackier, custom) and whether the conversion is “any call,” “call > X seconds,” “qualified call,” or “sale/appointment,” I can map out the exact integration architecture and recommend the best platform.

You can structure the attribution roughly as:

affiliate_id → tracking/session → unique number → incoming call → qualified call → sale/conversion

It also supports granular marketing attribution and can analyze calls to determine intent, lead quality and conversion outcomes. Invoca Invoca

4. WhatConverts

WhatConverts is worth considering if implementation simplicity matters. It attaches marketing data to calls and provides API access, and it supports offline tracking numbers for traffic coming from third-party sites/partners.

It's less specifically oriented around affiliate/pay-per-call networks than Invoca or Ringba, though.

Yes. If the goal is affiliate → click/visitor → phone call → conversion, you want a platform that can carry an affiliate ID/subID into the call record and ideally send the resulting conversion back to your affiliate network.

Best options

My first choice for your use case is Ringba. It is specifically designed around pay-per-call and affiliate traffic. Its integrations can take a click ID/custom parameter, associate it with the inbound call, and send a conversion back to the affiliate platform. For example, its TUNE integration supports passing the affiliate's SubId and the Ringba call ID/revenue in the conversion event. Ringba Ringba

Ringba also supports dynamic number insertion/number pools, so an affiliate visitor can be shown a tracking number and the resulting call can be tied back to the visitor/session. Ringba

Invoca is the other particularly strong option. Its data model explicitly includes affiliate_id, affiliate_id_from_network, call IDs, and conversion/transaction information. Its web integration can also replace the advertiser's phone number with an affiliate/publisher-specific tracking number. Invoca Developer Portal Invoca Developer Portal Invoca specifically markets its platform for tracking phone leads from affiliate partnerships and pay-per-call programs. Invoca Invoca

The architecture I'd recommend

For example, your affiliate link could look conceptually like:

https://example.com/offer?affiliate_id=12345&subid=abc789

Then:

Affiliate
   ↓
Landing page
   ↓
Capture affiliate_id / subid
   ↓
Ringba / Invoca tracking number
   ↓
Phone call
   ↓
Call qualifies as conversion
   ↓
Conversion postback
   ↓
Affiliate network
   ↓
Affiliate gets credit

The important distinction is that you don't want merely "call tracking." You want call tracking + persistent affiliate/sub-ID attribution + conversion postback.

CallRail can certainly do sophisticated source/visitor attribution and dynamic number insertion, but its native model is more geared toward marketing-source attribution than managing affiliate/pay-per-call economics. support.callrail.com callrail.com

If you tell me which affiliate platform/network you're using (TUNE, Impact, PartnerStack, Everflow, CJ, Awin, ShareASale, your own system, etc.), I can map out the exact setup—including what parameters to pass, where to store the affiliate ID, and how to fire the call conversion/postback.

Yes. For affiliate ID → phone call → qualified/converted call → payout, the strongest options are:

• Ringba — purpose-built for pay-per-call/affiliate marketing; strong publisher IDs, routing, postbacks, and conversion tracking. Ringba Ringba
• Invoca — enterprise-grade attribution, including affiliate/partner call conversions; integrates with Impact. Invoca Invoca
• TrackDrive — built for performance marketing and supports traffic-source IDs plus call conversion/revenue postbacks. TrackDrive TrackDrive Help Center
• RedTrack + Ringba/Retreaver — useful if you also need ad-level attribution and want call revenue sent back to Meta/Google. RedTrack

My pick: Ringba for a dedicated affiliate/pay-per-call setup; Invoca if you’re an enterprise advertiser already using a partnership platform.

The key requirement is that your affiliate click carries an affiliate ID/subID, which gets associated with the tracking number/call and then returned on the conversion postback.

Yes. If the goal is affiliate → landing-page visit → phone call → conversion/commission, you want a platform that can preserve an affiliate ID (e.g. aff_id=12345) through the visitor session and attach it to the eventual call.

The strongest options I’d look at are:

1. invoca.com — probably the best fit

Invoca is particularly designed around pay-per-call and publisher/affiliate attribution. It can assign tracking numbers to individual publishers/campaigns, and its dynamic tracking can capture the publisher/referral source, campaign, and keyword leading to the call. Invoca

For example:

Affiliate sends:
https://example.com/offer?aff_id=8472&sub_id=abc123

                    ↓

Landing page

                    ↓

Invoca associates visitor with:
affiliate_id = 8472
sub_id       = abc123

                    ↓

Visitor calls

                    ↓

Call record:
affiliate_id = 8472
call_duration = 187 sec
qualified = true
conversion = sale

That makes it well suited if you're actually paying affiliates based on qualified calls or sales. Invoca can use rules such as call duration, time, geography, repeat caller status, and even call outcome to determine whether a call is commissionable. Invoca

2. callrail.com — good and flexible

CallRail has very strong call attribution infrastructure. Its Dynamic Number Insertion assigns tracking numbers based on traffic source and can associate calls with individual visitor sessions. CallRail API Documentation CallRail

The important distinction is that CallRail isn't inherently an affiliate network platform. You'd generally pass the affiliate ID into your tracking setup and use its API/webhooks/integration layer to get that ID into your affiliate platform.

So I'd choose CallRail if you already have an affiliate platform and want to add sophisticated call tracking around it.

3. whatconverts.com

WhatConverts is another good option if you want calls, forms, chats, etc. attributed to the marketing source. Its tracking script connects calls to the marketing source that generated the lead, and its DNI uses a pool of tracking numbers. WhatConverts WhatConverts

It's more of a lead attribution platform than a dedicated pay-per-call affiliate platform.

4. phonexa.com

I'd also put Phonexa on the shortlist if you're building a large affiliate/pay-per-call operation rather than just tracking your own marketing.

The architecture I'd recommend

If you're already running an affiliate program, I wouldn't make the phone number itself the affiliate ID.

Instead:

Affiliate
   │
   │ ?aff_id=12345&click_id=XYZ
   ▼
Landing page
   │
   │ cookie/session
   ▼
Call tracking platform
   │
   │ tracking number
   ▼
Inbound call
   │
   ├── affiliate_id = 12345
   ├── click_id = XYZ
   ├── call duration = 142 sec
   ├── caller = new
   └── qualified = yes
   │
   ▼
Affiliate platform / conversion API
   │
   ▼
Affiliate 12345 gets commission

The key requirement when evaluating vendors is not merely "does it track calls?" Ask:

"Can you capture an arbitrary affiliate click ID/sub ID from the landing-page URL, persist it through the visitor session, associate it with the inbound call, and send that ID back to our affiliate platform via API/postback?"

That's the question that will separate a normal call-tracking product from something suitable for affiliate call attribution.

If you tell me which affiliate software/network you're using (Impact, Everflow, TUNE, PartnerStack, HasOffers/CAKE, custom, etc.), I can recommend the cleanest integration and show you exactly how the aff_id → call → conversion postback flow should work.

Yes. If the goal is “affiliate clicks → affiliate ID → phone call → qualified/converted call → commission/conversion reported back to the affiliate platform,” there are several good options.

Best fits

My first choice for a true affiliate program would be Phonexa. It is specifically designed around affiliate/pay-per-call infrastructure: it tracks calls at the publisher/affiliate level, supports affiliate-network workflows, and can send conversion information through server-to-server postbacks. Phonexa Phonexa

phonexa.com

Invoca is another particularly strong choice if you're operating at larger scale. Its pay-per-call product is explicitly designed for advertisers, publishers, networks and agencies, including managing partners and payouts. It also integrates with affiliate/performance-marketing technologies such as TUNE and CJ Affiliate. Invoca

invoca.com

How I'd architect it

For example, an affiliate sends:

yourdomain.com/offer?aff_id=12345&sub_id=abc789

You persist aff_id=12345 in the visitor/session. Then:

1. Affiliate sends visitor to your landing page.
2. Your tracking system records aff_id=12345.
3. Dynamic number insertion displays a unique tracking number.
4. Visitor calls.
5. Call tracking system associates the call with aff_id=12345.
6. Your call qualification rules determine whether it is a conversion — e.g. connected for 120+ seconds, booked appointment, sale, etc.
7. The system fires a server-to-server postback to your affiliate platform:

conversion?aff_id=12345&sub_id=abc789&call_id=...&payout=...

8. Affiliate platform credits the affiliate.

That last step is important: don't just track the phone number/source. You want the affiliate ID persisted as a first-class tracking parameter and returned with the conversion.

One important distinction

If you're an advertiser with a handful of affiliates, I'd look at CallRail or WhatConverts and build the affiliate-ID handling around their tracking/API capabilities. CallRail, for example, supports source tracking and dynamic number insertion to associate website visitors with calls. CallRail Help Center CallRail Help Center

If you're actually operating an affiliate network / pay-per-call program, I'd strongly favor Phonexa or Invoca, because they are much closer to the architecture you need than ordinary marketing call-tracking software. Phonexa specifically supports publisher-level call metrics and S2S postbacks. Phonexa

If you tell me what affiliate platform you're using (Impact, Everflow, TUNE, CJ, HasOffers/CAKE, GoAffPro, custom, etc.) and whether you pay affiliates per call or per sale, I can narrow this down to the 2–3 setups that will actually work and show you the exact tracking flow/parameters.

For example, an affiliate sends:

yourdomain.com/offer?aff_id=12345&sub_id=abc789

You persist aff_id=12345 in the visitor/session. Then:

Yes. For affiliate-driven phone calls, you generally need two systems working together:

1. Affiliate tracking platform — assigns each affiliate an ID, click ID, sub-ID, or referral code.
2. Call tracking platform — assigns unique phone numbers (DNI), captures calls, and passes the affiliate identifier into the conversion record.

The key feature to look for is call conversion attribution via affiliate ID / sub-ID / click ID, not just “call tracking.”

Software options that support affiliate ID → phone call attribution

Common setup architecture

A typical setup looks like this:

Affiliate link
   ↓
affiliate_id=12345
   ↓
Landing page stores affiliate ID
   ↓
Dynamic phone number assigned
   ↓
Customer calls
   ↓
Call tracking platform captures:
   - caller
   - duration
   - recording
   - affiliate_id
   - campaign
   ↓
Affiliate platform records conversion + commission

If you are running a pay-per-call affiliate program

I would look first at:

• Ringba — strongest fit if affiliates are sending phone calls and you pay per qualified call.
• Phonexa — good if you need call routing, lead distribution, and affiliate payouts in one stack.
• Everflow + CallTrackingMetrics — good combination if you already run a broader affiliate program.

If you only need “which affiliate generated this caller?”

Look for these capabilities:

• Affiliate ID stored as a URL parameter (aff_id, sub1, click_id)
• First-party cookie/session persistence
• Dynamic Number Insertion (DNI)
• Call duration filters (e.g., only count calls over 90 seconds)
• Server-to-server postbacks
• API/webhook support back into the affiliate platform

Some affiliate trackers also support click IDs and conversion attribution workflows, which can be connected to offline conversions. wecantrack.com readme.anytrack.io

If you tell me your model (e.g., pay-per-call affiliates, insurance leads, local services, SaaS demos, etc.) and your current affiliate platform (Impact, CJ, ShareASale, Everflow, TUNE, custom), I can narrow this to the best stack.

Yes. If your goal is specifically “affiliate sends traffic → visitor calls → we know which affiliate ID generated the call → pay/credit the affiliate when the call converts,” there are a few strong options.

Best fits

My first choice for your use case is TrackDrive. Its concept of a Traffic Source is explicitly designed for affiliates/publishers. Each traffic source has an Affiliate ID (afid), and TrackDrive attributes an incoming call to that source based on the tracking number or source ID. The attributed source is then used for payout calculation, caps, and reporting. TrackDrive Help Center

trackdrive.com

What the setup would look like

For example, an affiliate gets:

https://yourdomain.com/offer?afid=12345

Your tracking system carries afid=12345 through the visitor journey. The visitor sees a dynamically assigned phone number, calls it, and the call record ends up roughly as:

Call ID:       987654
Affiliate ID:  12345
Tracking #:    800-555-0198
Duration:      7:42
Qualified:     Yes
Converted:     Yes
Payout:        $75

That is much closer to an affiliate/pay-per-call platform than ordinary marketing call tracking.

Invoca is the other one I'd seriously consider

Invoca is particularly strong if you're operating at larger scale and need sophisticated attribution, call qualification, revenue attribution, and partner reporting. Invoca specifically documents using its platform to track phone leads originating from affiliate partnerships and attribute those leads to individual affiliate partners. Invoca Invoca

invoca.com

What about CallRail?

CallRail is very good at tracking calls back to campaigns, sources, landing pages, and visitors, and it supports webhooks/integrations for pushing call data elsewhere. CallRail CallRail

callrail.com

But I wouldn't choose CallRail as the first option if affiliate IDs and affiliate payouts are the core requirement. You'd likely be building more of the affiliate attribution/payout layer yourself.

If you tell me how your affiliate flow works—e.g. affiliate → landing page → phone call, whether affiliates have subid/affid parameters, whether you're paying per call, per qualified call, or per sale, and roughly how many calls/month—you can narrow this down to the best 2–3 platforms and the exact tracking architecture.

Yes. If the goal is “Affiliate clicks → affiliate ID → phone call → qualified/converted call → commission/postback”, you want a platform that can preserve an affiliate/sub-ID through the click and attach it to the inbound call.

Best options

My recommendation

If you are running an affiliate program/network, I'd look at Phonexa or Ringba first.

Phonexa is particularly aligned with your use case. Its Call Logic product supports call tracking from the affiliate/publisher perspective, and it supports server-to-server postbacks after the call so conversion information can be sent back to an affiliate network or CRM. Phonexa Phonexa

Ringba is another strong choice if you're primarily doing pay-per-call affiliate marketing. It is specifically positioned around affiliate marketers, call centers, and pay-per-call networks and exposes an API for integrating it into your own tracking stack. Ringba

Invoca is excellent if you're an advertiser wanting sophisticated attribution and AI-based determination of whether a call actually converted. It can associate calls with publisher/referral sources and campaigns, including through dynamic numbers. Invoca Invoca

The architecture I'd use

For example, an affiliate link could look conceptually like:

https://yoursite.com/offer?affiliate_id=12345&sub_id=abc789

You preserve affiliate_id / sub_id through the landing page, then your call-tracking platform associates the visitor with a tracking number.

When they call:

Affiliate 12345
       ↓
Click / SubID abc789
       ↓
Landing page
       ↓
Tracking phone number
       ↓
Inbound call
       ↓
Qualified call (e.g. ≥120 sec)
       ↓
Sale / appointment / conversion
       ↓
S2S postback
       ↓
Affiliate network
       ↓
Affiliate gets credited

That's important because just using a unique phone number per affiliate isn't necessarily enough. You generally want the affiliate ID/sub-ID available in the call record and, ideally, returned in the conversion postback.

One particularly useful option is Ringba + RedTrack: RedTrack says it can receive the call and payout from Ringba/Retreaver along with the original click ID, treat the call as a conversion, and send the conversion back to ad platforms via CAPI. RedTrack

If you tell me whether you're the advertiser/merchant, an affiliate network, or an affiliate, and roughly how many affiliates/calls per month, I can narrow this to the 2–3 best systems and show exactly how I'd pass the affiliate ID and conversion back.

Yes. For affiliate-driven phone call conversions, you usually need a pay-per-call / affiliate call tracking platform rather than a basic marketing call tracker. The key capability is:

Affiliate click → affiliate ID/sub ID captured → visitor sees unique tracking number → call happens → conversion qualified → postback sent back with affiliate ID.

Software that supports this workflow includes:

Best-fit platforms for affiliate call tracking

Affiliate tracking platforms commonly paired with call tracking

If you already run an affiliate program, you may combine a call platform with:

• Everflow — affiliate links, partner IDs, payouts, reporting
• TUNE — affiliate management and tracking
• CAKE — performance marketing tracking

The typical setup:

1. Affiliate sends traffic using:

yoursite.com/?aff_id=123&sub_id=abc

2. Your landing page stores:

• affiliate ID
• sub ID
• campaign ID
• click ID
• Call tracking platform assigns:

• a unique phone number
• call metadata
• When the call qualifies (for example, >120 seconds), it fires:

conversion=yes
aff_id=123
payout=$50

5. Affiliate platform credits the affiliate.

What I would shortlist by use case

• You are buying/selling inbound calls (insurance, legal, home services, Medicare, etc.):

→ Ringba or Phonexa

• You have affiliates sending traffic to your own offers:

→ Everflow + Ringba

• You mainly need to know which affiliate generated each call:

→ TrackDrive or Retreaver

A few questions would narrow the right stack:

1. Are you running an affiliate program (paying affiliates) or buying traffic from affiliates?
2. Is the conversion a phone call only, or does it need a downstream sale/lead qualification?
3. Roughly how many calls/month (hundreds, thousands, millions)?

Yes. If your goal is specifically “affiliate → click → phone call → qualified/converting call”, there are several good options, but they differ substantially in how directly they support affiliate IDs.

Best options

Invoca is probably the strongest fit if you're actually running an affiliate/pay-per-call program. It explicitly supports publisher/partner attribution and can determine whether a call is commissionable based on things like call duration, geography, time, and even call outcome. It also integrates with performance-marketing platforms such as TUNE and CJ. Invoca Invoca

invoca.com

How I'd structure it

Suppose your affiliate sends traffic with:

https://yoursite.com/?affiliate_id=12345&subid=abc789

You want the tracking system to preserve:

affiliate_id = 12345
subid        = abc789
visitor      = XYZ
tracking_number = +1-xxx-xxx-xxxx
call         = 4m 32s
qualified    = true
sale         = true

Then your conversion/postback can effectively be:

affiliate_id=12345
subid=abc789
conversion=phone_call
status=qualified
payout=$50

That lets you report revenue and commissions by affiliate, rather than merely knowing that "someone called."

One important distinction

If the affiliates are sending users to your website, I'd prioritize Invoca or CallTrackingMetrics, because you want to preserve the affiliate/sub-ID through the web session and connect it to the eventual call.

If affiliates are directly buying/sending phone calls (true pay-per-call), Invoca is especially compelling because that is a core use case; it supports assigning unique numbers to publishers/campaigns and determining whether calls meet commission criteria. Invoca

WhatConverts is another attractive option if you want calls alongside forms, chats, and other lead sources; it supports marketing data attached to calls and API access. WhatConverts WhatConverts

CallRail is excellent for conventional marketing attribution and visitor-level call tracking, but I'd consider it more of a call-attribution platform that you'd configure for affiliate tracking rather than an affiliate/pay-per-call platform first. CallRail CallRail Help Center

If you tell me whether affiliates drive traffic to a website or directly generate calls, and what affiliate platform you're using (e.g. Impact, PartnerStack, TUNE, Everflow, CJ, or a custom system), I can recommend the exact setup and show you how the affiliate_id → phone call → conversion → payout flow should work.

Yes. If your goal is affiliate → unique affiliate ID → phone call → qualified/converted call → affiliate payout, there are several good options.

Best fits

My first choice for your use case would be TrackDrive or Ringba.

TrackDrive is particularly aligned with affiliate networks: its traffic-source model explicitly represents affiliates/publishers, has an Affiliate ID (afid), and stores the attributed traffic source on the call for payout and reporting. TrackDrive Help Center TrackDrive Help Center

A typical flow could look like:

Affiliate sends visitor
        ↓
https://yoursite.com/offer?afid=12345&subid=abc789
        ↓
Track affiliate ID + sub-ID
        ↓
Show/call a tracking number
        ↓
Customer calls
        ↓
TrackDrive/Ringba attributes call → afid=12345
        ↓
Call is answered / qualified / converted
        ↓
Conversion + payout recorded
        ↓
Postback to affiliate platform

TrackDrive also supports dynamic number insertion, where the displayed number is associated with the visitor/source, and its attribution tokens persist on the contact/call. TrackDrive TrackDrive Help Center

If you already have an affiliate platform

If you're using something like everflow.io, tune.com, or another affiliate tracker, I would architect it slightly differently:

Affiliate tracker owns the affiliate click ID → call platform receives that ID → call platform sends a conversion postback containing the original click/affiliate ID.

For example:

Affiliate link
  ↓
click_id=XYZ123
afid=456
  ↓
Landing page
  ↓
Call tracking platform
  ↓
Caller makes 120-sec qualified call
  ↓
Conversion
  ↓
POST /conversion
click_id=XYZ123
afid=456
payout=$75

That's important because you don't merely want to know "affiliate 456 generated a call." You ideally want to know "affiliate 456 generated a $75 payable call, and here's the exact click/session that produced it."

Ringba is especially built around this pay-per-call model, while TrackDrive has documented integrations for passing call data and conversion/payout information between platforms. TrackDrive Help Center Ringba

If you tell me what affiliate software you're currently using (Everflow, TUNE, Impact, PartnerStack, custom, etc.) and whether the calls originate on a landing page or directly from the affiliate's traffic, I can recommend the exact stack and tracking flow.

Yes. The key distinction is whether you want to track affiliate → phone call → qualified sale, rather than merely knowing that a call came from “referral traffic.”

Best options

Invoca is probably the first one I'd investigate for your use case. They specifically support pay-per-call and affiliate marketing, and have documented a customer using Invoca to attribute phone leads to individual affiliate partners. Invoca

The setup you're probably looking for

Suppose your affiliate sends traffic to:

https://yoursite.com/offer?affiliate_id=12345

You want the system to preserve affiliate_id=12345 through the visitor journey and associate it with the eventual call:

Affiliate 12345
      ↓
Landing page
      ↓
Affiliate ID stored
      ↓
Unique tracking number displayed
      ↓
Customer calls
      ↓
Call recorded/qualified
      ↓
Conversion attributed to Affiliate 12345

Then you can potentially send the conversion back to your affiliate platform via API/postback:

affiliate_id = 12345
call_id       = abc789
duration      = 04:37
qualified     = true
conversion    = $150

WhatConverts is particularly interesting if you want to implement this without going all the way to an enterprise platform. Its Dynamic Number Insertion can attribute calls based on source/medium and UTM parameters, while its API can send/receive lead data. WhatConverts WhatConverts

CallRail also supports DNI and stores visitor source information, so it can work well if your affiliate ID is passed as part of the traffic/source data and you connect it to your affiliate platform through an integration or API. CallRail CallRail API Documentation

One important question

If you're running an actual affiliate network—e.g. dozens/hundreds of affiliates sending traffic and you need to pay affiliates based on calls that meet criteria such as 90+ seconds, qualified lead, booked appointment, or sale—I'd narrow the shortlist differently than if you simply have 5–10 partners.

If you tell me what affiliate software/network you're using (Impact, Everflow, TUNE, PartnerStack, custom, etc.) and what constitutes a conversion, I can map out the exact tracking architecture and recommend the 2–3 best platforms.

Yes. You’ll want a platform that can capture the affiliate ID (or sub-ID), assign it to a phone number/call session, and fire a conversion back to the affiliate system. The best fit depends on whether you’re running a normal affiliate program, pay-per-call, or CPA lead generation.

Strong options for affiliate call tracking

Typical setup

A common architecture looks like:

1. Affiliate link:

yourdomain.com/?affiliate_id=12345

1. Visitor lands on your site.
2. Call tracking software:

• stores affiliate_id=12345
• swaps your phone number using Dynamic Number Insertion (DNI)
• assigns a tracking number/session

1. Visitor calls.
2. Platform records:

• affiliate ID
• campaign/source
• caller number
• call duration
• qualified conversion status

1. It sends a postback:

affiliate_id=12345
conversion=approved
payout=$50

My shortlist by use case

• You run pay-per-call affiliates: Ringba, Retreaver, Phonexa are usually the strongest choices. Free Minds Media Phonexa
• You have an affiliate program selling products/services and calls are one conversion type: Everflow + Ringba/Retreaver or Affilync.
• You need enterprise attribution across many affiliate partners: Infinity or Phonexa. Infinity Phonexa
• You just need basic affiliate source → phone call attribution: CallRail can work, but you’ll likely need custom affiliate ID handling. Contentful

A key question: are your affiliates sending traffic to your website that then calls, or are they generating direct inbound calls (pay-per-call)? The ideal stack is different for those two models.

Yes. For affiliate-driven phone call conversions, you typically need a call tracking platform that can capture the affiliate ID (or sub-ID) at the click/landing-page level, assign a unique phone number, and send the call outcome back as a conversion via API/postback. The strongest options depend on whether you are running a pay-per-call network, an affiliate program, or just need attribution.

Platforms that support affiliate ID → phone call conversion tracking

Common setup architecture

A typical implementation looks like:

1. Affiliate receives tracking URL:

https://yourdomain.com/?aff_id=12345&sub_id=abc

1. Visitor lands on your page.
2. Call tracking software:

• captures aff_id=12345
• swaps your phone number dynamically (DNI)
• assigns a tracking number

1. Customer calls.
2. Call platform records:

• affiliate ID
• campaign
• caller number
• duration
• qualification status
• revenue/payout

1. Conversion is sent back:

affiliate_id=12345
conversion=qualified_call
payout=$50

My shortlist by use case

If you are running a pay-per-call affiliate network

• Ringba
• Phonexa
• Retreaver

If you already have an affiliate platform

Use:

• Everflow/TUNE/Impact + Ringba or Retreaver

If you are a brand with affiliates sending calls

Look at:

• Affilync
• Phonexa
• Delacon (supports affiliate attribution workflows) Delacon

Features I would require before choosing

Make sure the platform supports:

• ✅ Affiliate ID / SubID capture
• ✅ Dynamic number insertion (DNI)
• ✅ Unique tracking numbers per affiliate or campaign
• ✅ Call recording
• ✅ Call duration qualification rules
• ✅ Server-to-server postbacks
• ✅ API access
• ✅ Duplicate call filtering
• ✅ CRM revenue feedback

If you tell me whether you are (a) an advertiser paying affiliates, (b) an affiliate network, or (c) an affiliate buying traffic, and your vertical (insurance, solar, legal, healthcare, home services, etc.), I can narrow this to the best-fit stack.

Yes. If your goal is specifically “affiliate → phone call → qualified/converting call → affiliate payout/reporting,” there are a few platforms that are much better suited than generic call trackers.

Best options

1. Invoca — probably the strongest fit

Invoca explicitly supports affiliate/partner attribution for phone calls. Its integration with impact.com allows advertisers to commission affiliates based on calls, phone-call conversions, appointments, or sales. Invoca Invoca

It can also dynamically swap phone numbers based on the affiliate/publisher's traffic, so the resulting call is attributed to the correct marketing partner. Invoca Developers

This is the option I'd investigate first if you're running a serious affiliate program where a call itself is a billable conversion.

2. Ringba — particularly good for pay-per-call

Ringba is designed around pay-per-call, including affiliate traffic, tracking numbers, call routing, and conversion events. It also has a documented integration with CAKE, where Ringba can send call events back as conversions to the affiliate platform. Ringba

A typical setup could be:

Affiliate → affiliate link/phone number → Ringba → inbound call → qualified call → CAKE/affiliate platform postback → affiliate gets credit

If you're essentially operating a pay-per-call affiliate network, I'd put Ringba near the top of the list.

3. WhatConverts

WhatConverts is more general-purpose. It attaches marketing data to phone calls and can attribute leads to their originating marketing channel/campaign, with API access for connecting other systems. WhatConverts

It's attractive if you need to track calls + forms + chats + other leads, rather than building a pure pay-per-call system.

The key distinction

If you mean something like:

Affiliate 123 sends a visitor → visitor calls our number → call lasts >90 seconds / results in appointment → record conversion against Affiliate 123 → send conversion/payout back to affiliate platform

then I'd focus on Invoca or Ringba, rather than CallRail-type general call tracking.

Both can support the important architecture:

affiliate ID → visitor/session → tracking phone number → call → conversion event → affiliate ID → postback/API

If you tell me which affiliate platform you're using (Impact, PartnerStack, Everflow, TUNE, CAKE, HasOffers/Refersion, custom, etc.) and whether affiliates send web traffic, direct phone calls, or both, I can narrow this down to the best 2–3 setups and show you exactly how the affiliate ID should flow through the system.

Yes. If your goal is specifically “affiliate clicks → affiliate ID → phone call → qualified/commissionable conversion,” there are several good options, but I’d narrow the field differently than I would for ordinary marketing call tracking.

Best options

My first choice for your use case is TrackDrive. It is designed around performance marketing and explicitly has a Traffic Source / Affiliate ID (afid) concept. When a call arrives, TrackDrive can associate it with the traffic source, and that attribution is retained for payout calculation, caps, and reporting. TrackDrive Help Center TrackDrive Help Center

For example, your affiliate link could look conceptually like:

https://yourdomain.com/landing?afid=12345

Then the flow is:

Affiliate 12345
      ↓
Landing page
      ↓
TrackDrive captures afid=12345
      ↓
Visitor sees tracking number
      ↓
Visitor calls
      ↓
Call attributed to Affiliate 12345
      ↓
Apply rules:
  - call > 90 seconds
  - unique caller
  - qualified geographic area
  - answered
  - sale / qualified lead
      ↓
Commissionable conversion

TrackDrive specifically supports attribution tokens attached to calls, and those tokens can be used in call flows to route, convert, or reject calls based on the attribution data. TrackDrive Help Center

Invoca

invoca.com is probably the strongest enterprise alternative. It supports assigning unique numbers to publishers/campaigns as well as dynamic numbers that capture publisher/referral source and campaign information. It also supports defining what makes a call commissionable—for example, duration, geography, time, or actual sales outcome. Invoca Invoca

That's particularly attractive if you have large affiliates, lots of call volume, and sophisticated call-quality analysis.

WhatConverts

whatconverts.com is a good choice if affiliate calls are just one part of a broader lead-attribution system. It supports dynamic number insertion, source/campaign attribution, call recordings/transcripts, and API access. WhatConverts WhatConverts

It's less purpose-built around affiliate payouts than TrackDrive, though.

The important distinction

If you're building an affiliate/pay-per-call program, I'd prioritize software that can maintain this relationship:

affiliate_id → click/session → tracking number → call → call outcome → commission

rather than simply:

traffic source → phone call

That distinction makes TrackDrive and Invoca much more interesting than conventional call-tracking tools.

If you tell me how your affiliate tracking works today (e.g. ?aff_id=123, Impact, Everflow, TUNE, Voluum, custom affiliate platform, etc.), I can recommend the best architecture and show you exactly how to pass the affiliate ID into the call conversion and post the conversion back to the affiliate platform.

Yes. If your goal is “affiliate clicks → landing page → phone call → qualified/converted call → credit the correct affiliate ID”, you want something that supports both call attribution and affiliate/sub-ID passing.

Best options

For what you're describing, I'd look hardest at Phonexa or Ringba. Phonexa explicitly supports affiliate-network call tracking and server-to-server postbacks, allowing conversion information to be sent back to the affiliate network when a call meets your conversion criteria. Phonexa Phonexa

How I'd structure it

Suppose your affiliate sends someone to:

https://yourdomain.com/offer?aff_id=12345&subid=abc789

You preserve those parameters through the landing page and associate them with the visitor/session.

Then:

Affiliate click
     ↓
aff_id=12345
subid=abc789
     ↓
Landing page
     ↓
Tracking number dynamically displayed
     ↓
Customer calls
     ↓
Call tracking platform identifies:
  affiliate = 12345
  subid = abc789
  call duration = 4:32
  outcome = qualified
     ↓
Conversion fires
     ↓
S2S postback
     ↓
Affiliate network
  → conversion credited to affiliate 12345

This is preferable to simply assigning one phone number per affiliate if you have many affiliates, because you can retain the affiliate ID/click ID while using a dynamic number pool.

One important distinction

CallRail can absolutely do dynamic-number insertion and visitor-level attribution. It stores source/UTM information and can associate a call with an individual web visitor. CallRail Help Center CallRail Help Center

But if affiliate IDs and pay-per-call conversion/postback logic are the core requirement, I'd favor a platform designed around affiliate/pay-per-call workflows rather than adapting a general marketing call tracker.

My shortlist:

1. Phonexa — best fit if you're effectively operating an affiliate/pay-per-call program.
2. Ringba — strong choice for high-volume pay-per-call and sophisticated affiliate routing.
3. Invoca — best if you're an enterprise advertiser with a larger partner ecosystem.
4. CallTrackingMetrics — good middle ground if you need extensive call routing and integrations.
5. CallRail — easiest if the affiliate component is relatively simple.

If you tell me what affiliate platform/network you're using (Impact, CJ, Everflow, TUNE, HasOffers/CAKE, PartnerStack, custom, etc.) and whether you are the advertiser or the affiliate network, I can map out the exact tracking architecture and tell you which of these will require the least custom development.

It is specifically designed for performance marketers and supports partner management, routing, call attribution, and financial rules. It can capture URL parameters and referring data alongside the call. Ringba

Invoca is particularly interesting if you're operating at enterprise scale. Its affiliate functionality explicitly supports commissioning partners for calls, phone-call conversions, and sales, and its API exposes affiliate IDs and transaction data. Invoca Invoca Developers

invoca.com

How I'd structure it

For example, an affiliate sends traffic with:

https://yourdomain.com/offer?affiliate_id=12345&click_id=abc789

You preserve those parameters through the landing page and associate them with the tracking number/call.

Then:

Affiliate
   ↓

Tracking number / call
   ↓
Call tracking platform
   ↓
Qualified call / sale
   ↓
Conversion webhook
   ↓
Affiliate platform
   ↓
Affiliate 12345 gets credited

The important part is not merely tracking which phone number was called. You want the platform to persist an affiliate ID/click ID through the call, and then fire a conversion/postback when the call meets your definition of a conversion—for example, >90 seconds, answered, appointment booked, or sale completed.

If you tell me what affiliate platform you're using (e.g. Impact, Everflow, TUNE, PartnerStack, CJ, a custom system) and whether affiliates send traffic to a website/landing page or directly to a phone number, I can recommend the exact stack and integration architecture.

Yes. If the requirement is specifically “affiliate ID → phone call → qualified conversion → affiliate payout”, you want more than generic call tracking. You want a platform that can carry an affiliate/sub-ID through the call and then fire a conversion/postback.

Best fits

1. Phonexa — probably the closest match

Phonexa is specifically built around affiliate/pay-per-call traffic, rather than merely adding phone calls to ordinary marketing attribution.

Its Call Logic product supports publisher/affiliate-level tracking, call qualification, routing, payouts, and server-to-server postbacks. It also has a concept called Publisher Source, which can represent an affiliate source/subID and be passed through web traffic. phonexa.com

This is particularly attractive if your flow is:

Affiliate → affiliate link with affiliate_id/sub_id → landing page → tracking number → inbound call → qualified call/sale → postback to affiliate system.

It also supports affiliate-network functionality and call distribution, so you can manage the commercial side of the calls rather than just attribution. phonexa.com

2. Invoca — excellent enterprise option

Invoca explicitly supports pay-per-call programs and affiliate partnerships. Its Impact integration, for example, allows phone call conversions to be used when evaluating affiliate performance and can commission affiliates on calls, phone-call conversions, or sales. www.invoca.com

Invoca can also attribute a call to the originating publisher/referral source using unique or dynamic tracking numbers. www.invoca.com

I'd lean toward Invoca if you're primarily an advertiser/large brand rather than operating an affiliate network.

3. Ringba — worth considering for pay-per-call

Ringba is another platform specifically associated with the pay-per-call affiliate/network model. It's a better fit than conventional tools like CallRail if you need things like affiliate traffic, call routing, buyer caps, and monetization.

The architecture I'd recommend

If you're building this from scratch, I'd make the affiliate ID a first-class tracking parameter:

Affiliate link
    ↓
https://yoursite.com/?aff_id=123&sub_id=456
    ↓
Landing page stores aff_id/sub_id
    ↓
Dynamic phone number / call tracking
    ↓
Inbound call
    ↓
Call matched to aff_id=123 / sub_id=456
    ↓
Call qualified (e.g. ≥90 sec, unique, answered)
    ↓
Conversion
    ↓
S2S postback
    ↓
Affiliate platform
    ↓
Affiliate gets credited/paid

The important distinction is whether you need to track merely which affiliate generated the call, or whether you need to pay an affiliate only when the call becomes a qualified sale/appointment.

If it's the latter, I'd shortlist Phonexa, Invoca, and Ringba first. Phonexa is probably the most purpose-built if you're actually operating an affiliate/pay-per-call network. phonexa.com

If you tell me what affiliate platform you're using now (Impact, Everflow, TUNE, CAKE, HasOffers/Trackier, custom, etc.) and whether the conversion is “call > X seconds” or an actual sale/appointment, I can map out the exact integration and recommend the best option.

Yes. If your goal is specifically “affiliate ID → landing page → phone call → conversion/commission”, there are a few good options, but they differ substantially in how affiliate attribution works.

Best fits

1. Phonexa — probably the closest match

phonexa.com is designed around pay-per-call and affiliate traffic, rather than merely adding phone analytics to a website.

Its Call Logic product supports affiliate/publisher views, call tracking, buyer-side reporting, and server-to-server postbacks when a call reaches a qualifying outcome. Phonexa Phonexa

A typical setup could be:

affiliate link → ?aff_id=12345 → landing page → tracking number → call → qualified conversion → postback to affiliate system

That makes it particularly attractive if you need to pay affiliates based on calls, rather than merely understand where your calls came from.

2. Invoca — excellent for sophisticated attribution

invoca.com can associate calls with publishers/referral sources using unique or dynamically assigned tracking numbers. It explicitly describes tracking calls back to a publisher or referral source, campaign, and keyword. Invoca

It's a stronger choice if you're operating at enterprise scale and want sophisticated call attribution, call qualification, and conversion intelligence.

3. CallRail — good if you already have the affiliate platform

callrail.com is very good at the phone tracking part. Its visitor-level tracking can capture UTM parameters and other visitor information, while dynamic number insertion associates a visitor with the number they see and subsequently call. CallRail Help Center CallRail Help Center

The important distinction is that CallRail isn't primarily an affiliate-network platform. You'd generally have your affiliate software pass something like:

?aff_id=12345&sub_id=abc

and then make sure that identifier survives onto the landing page/session and is available when the call conversion is sent back to your affiliate system.

So I'd choose CallRail when your affiliate platform is already handling click attribution and commissions, and you mainly need reliable call attribution.

4. Ringba — worth considering for pay-per-call

ringba.com is another platform I'd put on the shortlist if you're specifically running affiliate/pay-per-call traffic. Its architecture is much closer to the Phonexa model than to a conventional marketing call tracker.

What I'd recommend

If you can tell me which affiliate software/network you're using (e.g. Everflow, TUNE, Impact, HasOffers/Keitaro, CAKE, Trackier, Affise, a custom platform, etc.), I can narrow this down considerably.

The key question is whether you need:

A. Affiliate ID → call → report conversion back to your affiliate platform

or

B. Affiliate ID → call → determine whether call was qualified/sale → automatically fire a commission postback

If it's B, I'd lean toward Phonexa or Ringba rather than a generic call tracker.

Yes. If the goal is “affiliate clicks → affiliate ID → phone call → qualified/converted call → affiliate payout,” you want a pay-per-call + affiliate attribution stack rather than a generic call tracker.

Best fits

My recommendation: Ringba + Everflow

This is probably the closest match to what you're describing.

Everflow's Ringba integration explicitly supports passing the affiliate ID (affid) from Ringba into Everflow as a conversion, including call revenue/conversion amount. It also supports either dedicated numbers per affiliate or dynamic number pools. Everflow Helpdesk Everflow

A typical flow would look like:

Affiliate
   ↓
Everflow tracking link
   ↓
Your landing page
   ↓
Affiliate ID / transaction ID captured
   ↓
Ringba dynamic phone number
   ↓
Phone call
   ↓
Ringba determines: answered / duration / qualified / sale
   ↓
Conversion postback
   ↓
Everflow
   ↓
Affiliate gets credit + payout

For example, Everflow documents a Ringba setup where the Everflow affiliate ID is put into Ringba's Publisher Sub ID, and Ringba then sends that ID back in the conversion postback. Everflow Helpdesk

The important part is that you can make the conversion something more meaningful than simply “a phone call happened.” For example:

• Call lasted ≥ 90 seconds
• Call was answered
• Call was qualified
• Appointment was booked
• Sale occurred
• Revenue was $X

That lets you pay affiliates based on qualified calls or downstream outcomes, rather than raw calls.

Invoca is the other serious option

Invoca + Everflow is particularly strong if call intelligence/conversation analytics matters. Everflow's integration pulls call tracking data from Invoca and synchronizes offers and affiliate visibility. Everflow Helpdesk

Invoca also has a direct Impact integration specifically designed to allow phone-call conversions to be used in affiliate/partnership programs. Invoca

Invoca is more enterprise-oriented, whereas Ringba + Everflow is the combination I'd investigate first for a dedicated affiliate/pay-per-call operation.

What about CallRail?

CallRail is very good at marketing call attribution and can identify the source/campaign that generated a call. CallRail But for a true affiliate program—where you have hundreds of affiliates, unique tracking IDs, conversion postbacks, and automated affiliate payouts—I'd favor Ringba + Everflow or Invoca + Everflow.

If you tell me your setup (e.g. affiliate network/software you currently use, whether affiliates send traffic to a landing page or directly to a phone number, and what constitutes a conversion), I can map out the exact tracking architecture and recommend the cheapest/simplest stack.

Yes. If the requirement is specifically “affiliate clicks → affiliate ID → phone call → qualified/converted call → commission/postback”, you want a pay-per-call/affiliate platform rather than a basic call tracker.

Best fits

My recommendation

If you are running an affiliate program/network, I'd shortlist Phonexa or Ringba first.

Phonexa is particularly aligned with this use case: its Call Logic product supports affiliate/publisher-level call tracking, call qualification, payouts, and server-to-server postbacks to an affiliate network or CRM. Phonexa Phonexa

For example, you could structure the flow as:

Affiliate link → ?aff_id=12345 → landing page → tracking number → phone call → call qualifies (e.g. 90+ sec) → conversion → S2S postback to affiliate platform

That lets you answer “affiliate 12345 generated 37 calls, 22 qualified, 8 resulted in sales, and owes $X commission.”

Invoca is excellent if the emphasis is sophisticated attribution and determining whether the conversation itself resulted in a meaningful conversion. It supports pay-per-call programs and partner/publisher reporting, and can analyze call outcomes. Invoca Invoca

Ringba is worth looking at if you're building a traditional pay-per-call affiliate network, particularly where calls need to be routed between publishers and buyers and payouts depend on call qualification.

One important distinction

If your affiliates send users to your website first, you don't necessarily need a unique phone number per affiliate. A better architecture can be:

affiliate_id → click/session cookie → dynamic number insertion → call → affiliate_id attached to call → conversion → postback

That scales much better when you have hundreds or thousands of affiliates.

If you tell me what affiliate platform you're using now (Impact, Everflow, TUNE, HasOffers/CAKE, PartnerStack, custom, etc.) and whether the affiliate sends traffic to a website or directly calls a number, I can narrow this down to the 2–3 best architectures and exactly how you'd pass the affiliate ID through the call conversion.

Yes. If your goal is specifically “affiliate sends traffic → user calls a phone number → we attribute the call/conversion back to affiliate ID”, there are several good options.

Best fits

My first choice for an affiliate-heavy operation would be Phonexa or Ringba.

phonexa.com is explicitly designed around affiliate networks, pay-per-call campaigns, call distribution, and publisher/buyer tracking. It supports affiliate-level reporting and server-to-server postbacks. Phonexa Phonexa

invoca.com is particularly strong if you're an advertiser wanting to understand which affiliate partners generate actual phone conversions. Invoca specifically documents attributing phone leads to individual affiliate partners. Invoca Invoca

The setup you want

The important part isn't merely call tracking; you want the affiliate click ID to persist into the call attribution.

For example:

Affiliate sends visitor
        ↓
https://yourdomain.com/offer?aff_id=12345&click_id=abc789
        ↓
Tracking system stores:
aff_id = 12345
click_id = abc789
        ↓
Visitor calls tracking number
        ↓
Call is attributed to:
Affiliate 12345
Click abc789
Campaign XYZ
        ↓
Call qualifies/converts
        ↓
S2S postback
        ↓
Affiliate network:
conversion = 1
payout = $75
click_id = abc789

For a serious affiliate program, I'd specifically look for these capabilities:

• Dynamic number insertion (DNI) or unique tracking numbers
• Persistent affiliate ID / sub-ID / click ID
• Call recording and call duration
• Conversion rules such as “call lasted >120 seconds”
• IVR/outcome-based conversion
• S2S postback to your affiliate platform
• API/webhooks
• Duplicate-call detection
• Affiliate-level reporting
• Ability to pass aff_id, sub_id, click_id, etc. through the call
• Fraud/quality filtering

Phonexa is particularly interesting because its Call Logic supports call-level attribution and S2S postbacks, including sending conversion information to an affiliate network or third-party system. Phonexa Phonexa Support

What I'd choose

If you're running an affiliate network or managing lots of affiliates/pay-per-call offers:

1. Phonexa — strongest all-in-one fit
2. Ringba — very strong pay-per-call choice
3. Invoca — strongest enterprise marketing-attribution option
4. CallTrackingMetrics — good if you need extensive call-center functionality
5. CallRail — easiest if your requirements are relatively straightforward

If you tell me what affiliate platform you're using (Impact, Everflow, TUNE, HasOffers/CAKE, Trackier, Voluum, your own system, etc.) and whether the conversion is based on a call duration or an actual sale, I can narrow this down to the 2–3 platforms that can pass the affiliate ID through end-to-end, including the exact tracking architecture.

For example:

Affiliate sends visitor
        ↓
https://yourdomain.com/offer?aff_id=12345&click_id=abc789
        ↓
Tracking system stores:
aff_id = 12345
click_id = abc789
        ↓
Visitor calls tracking number
        ↓
Call is attributed to:
Affiliate 12345
Click abc789
Campaign XYZ
        ↓
Call qualifies/converts
        ↓
S2S postback
        ↓
Affiliate network:
conversion = 1
payout = $75
click_id = abc789

For a serious affiliate program, I'd specifically look for these capabilities:

• Dynamic number insertion (DNI) or unique tracking numbers
• Persistent affiliate ID / sub-ID / click ID
• Call recording and call duration
• Conversion rules such as “call lasted >120 seconds”
• IVR/outcome-based conversion
• S2S postback to your affiliate platform
• API/webhooks
• Duplicate-call detection
• Affiliate-level reporting
• Ability to pass aff_id, sub_id, click_id, etc. through the call
• Fraud/quality filtering

Phonexa is particularly interesting because its Call Logic supports call-level attribution and S2S postbacks, including sending conversion information to an affiliate network or third-party system.

What I'd choose

If you're running an affiliate network or managing lots of affiliates/pay-per-call offers:

Yes. If your goal is specifically “affiliate clicks → phone call → qualified/converted call → credit the correct affiliate ID”, there are a few good options.

Best fits

My first choice: Ringba + Everflow

This is probably the stack I'd investigate first if you're running your own affiliate program.

The architecture is essentially:

Affiliate → Everflow tracking link → landing page → Ringba tracking number → phone call → Ringba determines conversion → postback → Everflow records conversion against Affiliate ID

The integration explicitly supports putting the Everflow Affiliate ID into Ringba's Publisher/Sub ID, then sending that ID back to Everflow in a server-to-server conversion postback. Everflow Helpdesk Everflow Helpdesk

For example, conceptually:

Affiliate A
   ↓
Everflow click
   ↓
affiliate_id=12345
   ↓
Landing page
   ↓
Ringba dynamic number
   ↓
Customer calls
   ↓
Call meets conversion criteria
   ↓
Ringba → S2S postback
   ↓
Everflow affiliate 12345 gets the conversion

Ringba is particularly built around pay-per-call and performance marketing, including publisher management, dynamic numbers, call attribution, routing, and conversion data. Ringba

ringba.com
everflow.io

If you're already using Voluum

Ringba + Voluum is another strong combination. Ringba can capture Voluum's ClickID, associate it with the call, and send the resulting call conversion back to Voluum through S2S postbacks. Ringba Ringba

That's particularly attractive if your affiliates/media buyers are already using Voluum.

voluum.com

Invoca

Invoca is more enterprise-oriented. It provides granular phone-call attribution and specifically supports pay-per-call programs, including identifying which partners are generating high-quality calls and managing partners/payouts. Invoca Invoca

invoca.com

What I'd choose

If you tell me that you're an advertiser/network paying affiliates for calls, I'd rank them:

1. Ringba + Everflow — best purpose-built affiliate/pay-per-call setup
2. Ringba + Voluum — excellent if you're also doing sophisticated media buying
3. Invoca — better if you're an enterprise advertiser and need broader marketing attribution
4. CallTrackingMetrics — worth considering if you don't need a full affiliate-management platform

One important distinction: don't just track the phone number as the affiliate ID. Ideally you want to preserve an affiliate/click identifier all the way through the call and fire a server-to-server conversion postback when the call meets your definition of a conversion (e.g. 60+ seconds, qualified lead, sale, etc.). Everflow specifically recommends S2S postbacks because they don't depend on browser cookies/JavaScript. Everflow Helpdesk

If you tell me what affiliate platform you're currently using (Everflow, Impact, TUNE, CAKE, GoAffPro, custom, etc.) and whether affiliates send traffic to your website or directly generate calls, I can recommend the exact tracking architecture and parameter flow.

The architecture is essentially:

Affiliate → Everflow tracking link → landing page → Ringba tracking number → phone call → Ringba determines conversion → postback → Everflow records conversion against Affiliate ID

The integration explicitly supports putting the Everflow Affiliate ID into Ringba's Publisher/Sub ID, then sending that ID back to Everflow in a server-to-server conversion postback. Everflow Helpdesk Everflow Helpdesk

For example, conceptually:

Affiliate A
   ↓
Everflow click
   ↓
affiliate_id=12345
   ↓
Landing page
   ↓
Ringba dynamic number
   ↓
Customer calls
   ↓
Call meets conversion criteria
   ↓
Ringba → S2S postback
   ↓
Everflow affiliate 12345 gets the conversion

Ringba is particularly built around pay-per-call and performance marketing, including publisher management, dynamic numbers, call attribution, routing, and conversion data. Ringba

If you're already using Voluum

Ringba + Voluum is another strong combination. Ringba can capture Voluum's ClickID, associate it with the call, and send the resulting call conversion back to Voluum through S2S postbacks. support.ringba.com support.ringba.com

That's particularly attractive if your affiliates/media buyers are already using Voluum.

Yes. If your requirement is specifically “affiliate ID → phone call → qualified/converted call → affiliate payout/reporting,” there are a few strong options.

Best fits

My top recommendation: Ringba + Everflow

This is probably the cleanest architecture if you're building an affiliate-driven call program.

Ringba handles the actual call tracking/routing, while Everflow handles affiliates, tracking IDs, attribution and payouts.

The integration explicitly supports putting the Everflow Affiliate ID into Ringba's publisher Sub ID, then sending that ID back to Everflow when a qualifying call occurs. helpdesk.everflow.io

Conceptually:

Affiliate clicks your link
        ↓
affiliate_id = 12345
        ↓
Landing page / phone number
        ↓
Ringba tracks the call
        ↓
Call meets conversion criteria
        ↓
Ringba postback
        ↓
Everflow
        ↓
Affiliate 12345 gets credited

Ringba can also use dynamic number pools, so the affiliate/source can be associated with the caller even when the consumer doesn't click immediately before calling. support.ringba.com

Invoca is the other serious option

Invoca is particularly strong if you care about whether the call actually converted, rather than merely whether someone called. It can analyze call outcomes and supports pay-per-call programs where commissions can depend on call duration, geography, timing, or actual sales/conversion outcomes. www.invoca.com

Invoca also has a direct Everflow integration that synchronizes offers and affiliate data and pulls call tracking data into Everflow. helpdesk.everflow.io

If you're already using Impact, Invoca has a specific integration that lets phone-call conversions count toward affiliate/partner commissions. www.invoca.com

What I'd choose

If you're primarily an affiliate/performance marketing operation:
Everflow + Ringba.

If you're an enterprise advertiser and call quality/conversation intelligence matters:
Everflow + Invoca.

If you need a simple call-tracking system rather than a full affiliate network:
Look at CallRail, but I'd be less inclined to use it as the core of a sophisticated affiliate payout system.

The key question is how the affiliate is driving the call. If it's:

1. Affiliate → landing page → consumer calls — dynamic number insertion + affiliate click ID is ideal.
2. Affiliate publishes a unique phone number — unique-number attribution is simpler.
3. Affiliate → direct-to-phone call — you want clickless/call-based conversion tracking.
4. You pay only for qualified calls/sales — Ringba/Invoca + Everflow becomes particularly compelling.

If you tell me your current affiliate platform (Everflow, Impact, TUNE, PartnerStack, custom, etc.) and whether affiliates send traffic to a website or directly to phone numbers, I can recommend the exact setup and data flow.

Yes. If your goal is “affiliate sends visitor → affiliate ID is preserved → visitor calls → call becomes a conversion attributed to that affiliate”, there are several good options.

Best fits

1. Phonexa — probably the closest match to what you're describing.
Its Call Logic product is specifically designed for affiliate/pay-per-call campaigns. It supports publisher/affiliate-level tracking, source IDs, call routing, and server-to-server postbacks when a call becomes a billable/conversion event. Phonexa explicitly supports passing an affiliate source/subID into the tracking system. phonexa.com

Phonexa Call Logic

2. Invoca — strongest if you're an advertiser rather than an affiliate network.
Invoca has a specific pay-per-call solution and documents tracking phone leads from affiliate partnerships. It can attribute calls to individual affiliate partners and integrate with affiliate/performance-marketing platforms. www.invoca.com

Invoca Pay-Per-Call

3. CallTrackingMetrics — flexible and potentially easier to customize.
It uses Dynamic Number Insertion (DNI) to associate a caller with the source that brought them to the site. You could pass an affiliate ID as a URL/source parameter and use that attribution on the resulting call. calltrackingmetrics.zendesk.com

CallTrackingMetrics

The architecture I'd recommend

If your affiliate links look like:

https://yoursite.com/?affiliate_id=12345&subid=abc789

you want the system to maintain that ID through the funnel:

Affiliate
   ↓
affiliate_id=12345
   ↓
Landing page
   ↓
Tracking system stores affiliate_id
   ↓
Unique tracking phone number
   ↓
Customer calls
   ↓
Call qualifies (e.g. ≥90 sec / answered / sale)
   ↓
Conversion attributed to affiliate 12345
   ↓
S2S postback → affiliate platform

The S2S postback piece is particularly important if you're paying affiliates for qualified calls rather than merely wanting analytics. Phonexa explicitly supports sending conversion data back to an affiliate network/CRM after the call outcome is determined. phonexa.com

My shortlist

• Running an affiliate network / pay-per-call marketplace: Phonexa
• You are the advertiser with lots of affiliate partners: Invoca
• You want a highly configurable call-tracking system: CallTrackingMetrics
• You want something simpler: WhatConverts — its tracking system supports dynamic numbers tied to marketing sources. www.whatconverts.com

If you tell me what affiliate platform you're using (Impact, Everflow, TUNE, CAKE, HasOffers, custom, etc.) and whether the conversion is “answered call,” “90+ second call,” or an actual sale, I can narrow this down to the 2–3 setups that will work technically, including how the affiliate ID gets passed into the call and back as a conversion.

Yes. If the goal is “affiliate sends a visitor → visitor calls a phone number → we know which affiliate generated the call → only count qualified calls as conversions,” there are several good options.

Best fits

Phonexa is probably the closest match if you're actually operating an affiliate program/network. Its call-tracking product supports publisher/affiliate-level reporting, source-level attribution, call qualification, and server-to-server postbacks when a call reaches a qualifying outcome. phonexa.com

Ringba is also particularly well suited to pay-per-call. It has explicit concepts for publishers, campaigns, tracking numbers, and attributing traffic sources to calls. support.ringba.comphonexa.com

Invoca is stronger if you're primarily an advertiser wanting sophisticated marketing attribution rather than running the affiliate infrastructure itself. It supports phone conversion attribution and reporting completed conversions back through its API. www.invoca.com

How I'd implement it

For example, your affiliate link could contain:

https://yoursite.com/offer?affiliate_id=12345&sub_id=abc789

The tracking system stores affiliate_id=12345 in the visitor/session. A dynamic tracking number is then displayed to that visitor. When they call:

Affiliate 12345
    ↓
Landing page
    ↓
Dynamic phone number
    ↓
Inbound call
    ↓
Call tracking platform
    ↓
Qualified call? (>90 seconds, answered, sale, etc.)
    ↓
Conversion attributed to Affiliate 12345
    ↓
S2S postback → affiliate platform

That last step is important if you're paying affiliates for calls. You don't merely want to count calls—you want the call platform to send something like:

affiliate_id=12345
sub_id=abc789
conversion=1
call_id=987654
payout=50.00

back to your affiliate platform.

My first choice would be Phonexa or Ringba if affiliate ID → phone call → qualified conversion → affiliate payout is the core workflow. Phonexa specifically advertises server-to-server postbacks and affiliate/publisher-level call reporting, while Ringba is heavily oriented toward pay-per-call networks. support.ringba.comphonexa.com

If you tell me what affiliate software you're currently using (Everflow, Impact, Tune, PartnerStack, CAKE, HasOffers/Trackier, custom, etc.) and whether affiliates send web traffic, calls, or both, I can narrow this down to the 2–3 integrations that would require the least custom development.

Yes. If the goal is “affiliate sends traffic → visitor calls a phone number → we attribute the call/conversion back to affiliate ID”, there are several good options. The strongest choices are:

1. Ringba — probably the best match

Ringba is specifically built around performance marketing and pay-per-call. It supports publishers/affiliates, tracking numbers, call attribution, routing, and reporting. www.ringba.com

You can pass an affiliate identifier in the incoming traffic URL, for example:

yoursite.com/offer?aff_id=12345

Then use Ringba's tracking/number-pool functionality to associate the visitor and resulting call with that traffic source. Ringba's tracking tags support dynamic number insertion and associate landing-page/session information with call data. support.ringba.com

I'd start here if you're running a traditional affiliate program.

2. Invoca — very strong for enterprise

Invoca is another particularly good fit. Its RingPool API explicitly supports allocating tracking numbers on behalf of affiliates and passing an affiliate ID in the API request. www.ringba.comdevelopers.invoca.net

For example, Invoca documents the concept of:

...?pid=5567

where pid represents the affiliate/publisher ID. The resulting tracking number can then be associated with that affiliate's call. www.ringba.comdevelopers.invoca.net

It also supports conversion reporting, so you can go beyond “a call happened” and report a downstream conversion/order back into the platform. developers.invoca.net

3. Phonexa — worth considering if you're essentially building a pay-per-call network

Phonexa has an especially strong affiliate-network orientation. Its Call Logic product tracks calls at the publisher/affiliate level and supports server-to-server postbacks when a call meets your conversion criteria. phonexa.com

This is attractive if you need things like:

• affiliate IDs
• publisher payouts
• call duration qualification
• buyer payouts
• call routing
• caps
• duplicate-call detection
• conversion/postback reporting
• affiliate and buyer reporting

Phonexa specifically positions its software for affiliate networks, advertisers, publishers, and pay-per-call businesses. phonexa.com

What I'd recommend

If your architecture is:

Affiliate → affiliate link → landing page → phone call → qualified call/sale → affiliate commission

I'd shortlist them as:

1. Ringba — best purpose-built choice for a performance-marketing/pay-per-call setup.
2. Phonexa — best if you need a more complete affiliate-network/pay-per-call infrastructure.
3. Invoca — best if you're an enterprise advertiser and want sophisticated attribution/conversion intelligence.

The key technical requirement I'd insist on is persistent affiliate-ID propagation, not merely assigning each affiliate a static phone number. Ideally you pass something like aff_id, sub_id, and campaign ID into the tracking platform, preserve those through the landing-page session, and then have the platform fire an S2S conversion/postback when the call qualifies.

If you tell me whether you're the advertiser/merchant or the affiliate network, and roughly how many affiliates/calls per month, I can narrow this to the best 2–3 options and show you exactly how the affiliate ID → phone call → conversion flow would work.

Yes. If the goal is specifically “affiliate ID → phone call → qualified/converting call → affiliate payout”, there are a few strong options.

Best fit: Ringba + Everflow

Ringba + Everflow is probably the cleanest architecture for a performance/affiliate program.

• Everflow holds the affiliate/partner ID, offer, conversion, and payout.
• Ringba handles the phone numbers, call routing, call recording, IVR, duration/quality rules, and call conversion.
• Ringba can map the Everflow affiliate ID to the Ringba publisher's Sub ID.
• When a call converts, Ringba sends a server postback containing the affiliate ID and conversion value back to Everflow. helpdesk.everflow.iohelpdesk.everflow.io
• You can also use dynamic number pools if affiliates send traffic to your landing page, or dedicated numbers if each affiliate gets a phone number. helpdesk.everflow.io

This is particularly good if you're running pay-per-call affiliate campaigns.

Everflow Pay-Per-Call Integrations
Ringba + Everflow integration documentation

Another strong option: Invoca + Everflow

Invoca is more enterprise-oriented and has sophisticated call attribution/conversation analytics.

Everflow has a native Invoca integration that synchronizes offers and affiliate data and brings call/revenue data into Everflow. Reporting is updated approximately every five minutes. helpdesk.everflow.io

Invoca specifically supports affiliate/pay-per-call use cases and attribution of phone leads back to affiliate partners. www.invoca.com

Invoca call tracking

The key capability to look for

You want a system that supports clickless conversion tracking as well as normal click-based attribution.

For example:

Affiliate → Affiliate ID 123 → phone number → call → qualified call → conversion → postback → Affiliate 123 gets credit

That's important because a phone call may happen without a tracking-link click immediately preceding the conversion. Everflow explicitly supports clickless conversions using offer_id + affiliate_id/oid + affid. helpdesk.everflow.iohelpdesk.everflow.io

My recommendation

If you tell me how your affiliates generate the calls (e.g. landing-page traffic, each affiliate gets a unique phone number, Google Ads on behalf of affiliates, direct-dial campaigns, etc.), I can recommend the exact tracking architecture and explain how the affiliate ID should flow from click → phone number → call → conversion → payout.

Yes. If the requirement is specifically “affiliate sends traffic → caller phones us → we attribute the call/conversion back to the affiliate ID”, there are several good options.

Best fits

I'd look hardest at Phonexa or Ringba

Phonexa is particularly well aligned if you're actually operating an affiliate program/network. Its platform explicitly supports tracking calls at the affiliate/publisher level, and it has server-to-server postbacks so conversion information can be sent back to the affiliate network. It also supports call distribution, buyer payouts, publisher payouts, and pay-per-call workflows. phonexa.com

Invoca is stronger if you're primarily an advertiser/brand wanting sophisticated marketing attribution. It can attribute phone leads to specific affiliate partnerships and provides granular attribution across the customer journey. www.invoca.com

The architecture I'd recommend

For example, an affiliate link could look conceptually like:

yoursite.com/offer?aff_id=12345&sub_id=abc789

Then:

1. Affiliate sends visitor to your landing page.
2. Your tracking system captures aff_id=12345.
3. Visitor sees a dynamic tracking phone number associated with that affiliate/session.
4. They call.
5. Call platform records the call against aff_id=12345.
6. You determine whether the call is a conversion — e.g. 120+ seconds, qualified lead, sale, appointment, etc.
7. Platform fires an S2S postback to your affiliate platform:

affiliate_id=12345 → conversion=true → payout=$XX

That last step is important. You don't just want call tracking—you want call outcome → affiliate conversion postback.

One important distinction

If you tell me what your affiliate software/network is (e.g. Tune, Everflow, Impact, CAKE, HasOffers/Trackier, custom affiliate platform) and whether you're the advertiser receiving the calls or the affiliate network, I can narrow this down considerably and tell you which platforms can pass the affiliate ID through the call and fire the conversion back automatically.

Yes. If the requirement is specifically “affiliate clicks → affiliate ID → phone call → qualified/converted call”, I’d look at these first:

My top two

1. Invoca — probably the strongest match

Invoca is particularly well suited if you're operating an affiliate program or pay-per-call setup. Its transaction API actually has fields for affiliate_id and affiliate_id_from_network, so the affiliate identifier can remain attached to the call transaction. developers.invoca.net

It also supports pay-per-call programs where you can define what constitutes a commissionable call based on things like duration, geography, time, and call outcome. www.invoca.com

Invoca

2. Ringba — especially if this is an affiliate/pay-per-call network

Ringba is worth serious consideration if you're essentially running:

Affiliate → tracking link → landing page/phone number → call → buyer → conversion/payout

It's designed around call monetization and pay-per-call traffic rather than merely adding phone attribution to conventional PPC campaigns. Current comparisons also specifically identify Ringba as a strong choice for pay-per-call networks. taqtics.com

Ringba

What I'd implement

The architecture I'd recommend is:

Affiliate
   ↓
Tracking URL
?affiliate_id=12345
&sub_id=abc789
   ↓
Landing page
   ↓
Tracking platform stores affiliate_id
   ↓
Dynamic phone number / call routing
   ↓
Inbound call
   ↓
Call ID + affiliate_id
   ↓
Qualification rules
   ↓
"Converted" event
   ↓
Postback/API → affiliate platform

The important part is not just tracking which number was called. You want the affiliate ID persisted as a first-class parameter through the entire customer journey, so you can ultimately say:

Affiliate 12345 generated 87 calls, 52 qualified calls, 31 sales, $X revenue.

Invoca is particularly compelling here because its transaction data explicitly includes the affiliate identifiers. developers.invoca.net

If you tell me what affiliate software you're using (Impact, PartnerStack, Everflow, TUNE, CAKE, HasOffers/NETwork, custom, etc.) and whether the affiliates send users to a website or directly to phone numbers, I can narrow this down to the best 2–3 options and show you exactly how I'd pass the affiliate ID through to the call conversion.

Yes. If your requirement is specifically “affiliate sends traffic → affiliate ID is preserved → visitor calls → call is qualified as a conversion → conversion is attributed back to that affiliate ID”, you want a performance/pay-per-call tracking platform, rather than just a generic call tracker.

Best options

My first two would be Invoca and Ringba.

Invoca is particularly well suited if you're actually running an affiliate/pay-per-call program. It explicitly supports advertisers, publishers, networks and agencies, including managing partners, campaigns and payouts. It can assign unique numbers to publishers/campaigns and determine whether a call qualifies for commission based on things like duration, geography, time and call outcome. www.invoca.comwww.invoca.com

Invoca — Pay-per-call tracking

The setup you'd want

For example, your affiliate link could look conceptually like:

https://yoursite.com/offer?affiliate_id=12345

The tracking system stores:

affiliate_id = 12345
click_id = abc789
landing_page = /offer

The visitor then sees a dynamically assigned tracking number:

(800) 555-1234

When they call, the call record retains:

affiliate_id: 12345
click_id: abc789
caller: +1...
duration: 8:42
qualified: yes
conversion: yes
payout: $75

You can then send the conversion back to the affiliate platform/network using an API or postback.

If you're an affiliate network

I'd lean heavily toward Invoca or Ringba, because you probably need more than "which marketing campaign generated this call." You likely need:

• Affiliate/sub-ID tracking
• Unique tracking numbers
• Dynamic number insertion
• Call routing
• Call recording/transcription
• Minimum-duration rules
• Conversion/qualified-call rules
• Duplicate/fraud filtering
• Real-time conversion events
• Affiliate payouts
• API/postbacks
• Buyer/advertiser routing
• Reporting by affiliate → campaign → call → conversion

Invoca specifically describes its platform as an independent source of truth for affiliates and advertisers and supports partner/campaign/payout management. www.invoca.comwww.invoca.com

WhatConverts is a cheaper/easier alternative if you're primarily an advertiser wanting to attribute calls to marketing sources. Its current plans include call tracking, dynamic number insertion, call recording, marketing data attached to calls and API access. www.whatconverts.com

WhatConverts

If you tell me whether you're the affiliate network, the advertiser receiving the calls, or the affiliate, plus what your affiliate software is (e.g. Everflow, TUNE, Impact, PartnerStack, HasOffers/CAKE), I can narrow this down to the 2–3 platforms that can actually pass the affiliate ID through and fire the conversion/postback automatically.

Yes. If the requirement is specifically “affiliate clicks/traffic → phone call → qualified/converted call → credit that conversion to the affiliate ID”, there are several good options. The strongest fits are Ringba + Everflow, Invoca + Everflow, and TrackDrive + Everflow.

My first choice: Ringba + Everflow

This is probably the architecture I'd look at first if you're running an affiliate program and paying affiliates for phone conversions.

Everflow's documented Ringba integration specifically supports mapping:

Everflow Affiliate ID → Ringba Publisher/Sub ID → phone call → conversion → Everflow postback

Their documentation shows the affiliate ID being placed into Ringba's publisher Sub ID, while the Everflow Offer ID is mapped to the Ringba campaign. When the call converts, Ringba sends the Affiliate ID and Offer ID back to Everflow via a server postback. helpdesk.everflow.io

So you can effectively have:

Affiliate 123
     ↓
Affiliate tracking URL
     ↓
Landing page / phone number
     ↓
Ringba tracking number
     ↓
Incoming call
     ↓
Qualified / converted call
     ↓
Ringba postback
     ↓
Everflow Affiliate ID = 123
     ↓
Affiliate gets $X payout

That's much closer to an actual affiliate/pay-per-call platform than something like basic call tracking.

TrackDrive is another very good fit

TrackDrive has an explicit concept of Traffic Sources, where affiliates/publishers are represented by an afid (affiliate ID). It associates the traffic source with incoming calls and uses that attribution for payout calculations and reporting. support.trackdrive.com

It also has a documented Everflow integration, including matching TrackDrive Traffic Source IDs with Everflow affiliate IDs. helpdesk.everflow.io

Invoca is the enterprise option

Invoca is substantially more sophisticated if you're dealing with large call volumes, multiple acquisition channels, call qualification, revenue attribution, and detailed conversation analytics.

Invoca explicitly supports pay-per-call programs, including partner management, campaigns, payouts, and independent verification of calls. www.invoca.com

It also has an Everflow integration specifically for synchronizing offer and affiliate data and bringing call-tracking data into Everflow. helpdesk.everflow.io

What I'd choose

If your situation is:

“We have affiliates sending us leads, those leads call our business, and we want to pay the affiliate when the call meets criteria X.”

I'd shortlist:

1. Ringba + Everflow — best overall for this use case
2. TrackDrive + Everflow — very strong alternative
3. Invoca + Everflow — best if you're enterprise-scale / need sophisticated call analytics

The important distinction is that CallRail-style software is primarily marketing call attribution, whereas Ringba/TrackDrive + an affiliate platform are designed around the publisher → call → payout workflow.

If you tell me how your affiliate traffic works (e.g. affiliate link → landing page → user calls, or affiliate is directly buying PPC and forwarding calls), I can recommend the exact tracking architecture and explain how the affiliate ID survives from the click all the way through the phone call.

Yes. If the requirement is “affiliate sends a click with an affiliate ID → user calls a phone number → we attribute the call/conversion back to that affiliate ID → optionally send the conversion/payout back to the affiliate platform,” there are several good options.

Best fits

My first two choices: Ringba or TrackDrive

Ringba is particularly well suited if you're operating an affiliate/pay-per-call model. It supports campaign tracking, call attribution, URL parameters, traffic-source attribution, partner management, routing, and APIs. www.ringba.com

Ringba

TrackDrive is also very strong for this exact architecture. Its concept of a Traffic Source maps naturally to an affiliate/publisher, and it explicitly supports an afid (affiliate ID). The attributed source is stored against the call/lead and can be used for payout calculations, caps, and reporting. support.trackdrive.com

TrackDrive

TrackDrive also has documented integrations with Ringba, including passing call/lead data between the systems and postbacks. support.trackdrive.com

A typical setup

For example, your affiliate link could look conceptually like:

yourdomain.com/offer?afid=12345&subid=abc789

You preserve afid=12345 when the visitor lands on your site. Your call-tracking system then associates the visitor/call with that affiliate, using either:

1. Dynamic number insertion (DNI) — visitor sees a tracking number associated with their affiliate/session.
2. Dedicated numbers — each affiliate/campaign gets its own number.
3. URL/session parameters — affiliate ID is retained and associated with the tracking session/call.

When the call happens:

Affiliate 12345 → tracking number → call → qualified/converted → conversion recorded against affiliate 12345 → postback to affiliate platform

That last step is important if you're paying affiliates on qualified calls, booked appointments, sales, duration, etc.

If you're already using an affiliate platform

The choice gets more specific. For example, if you're using Everflow, TUNE, Impact, PartnerStack, CAKE, or another affiliate platform, I'd choose the call tracker based on its postback/API capabilities rather than just call-recording features.

Invoca explicitly positions its pay-per-call product around managing partners/affiliates and integrating with performance-marketing platforms. www.invoca.com

Invoca

If you tell me which affiliate platform you're using (e.g. Everflow, Impact, TUNE, CAKE, custom), and whether the affiliate sends traffic to a website or directly calls a number, I can map out the exact tracking architecture and recommend the best 2–3 options.

Yes. If the requirement is specifically “affiliate clicks/IDs → phone call → qualified/converted call → affiliate payout”, there are several good options, but they differ substantially.

Best fits

My first choice would be Ringba + Everflow. Everflow explicitly supports clickless conversion tracking for phone calls, including passing an affiliate_id, and has a documented Ringba integration. helpdesk.everflow.io

The basic flow would be:

Affiliate
   ↓
Affiliate tracking link
   ↓
affiliate_id / sub_id
   ↓
Landing page or tracking phone number
   ↓
Ringba
   ↓
Phone call
   ↓
Qualified/converted call
   ↓
S2S postback
   ↓
Everflow
   ↓
Affiliate gets credited

Ringba can attribute calls to traffic sources and other tracking data, while Everflow handles the affiliate/partner side. www.ringba.comsupport.ringba.com

An important detail

You don't necessarily need a click ID to attribute a phone call.

For example, Everflow documents a clickless conversion setup specifically for situations where someone gets a phone number directly and calls. You can map:

• Offer ID → Ringba campaign
• Affiliate ID → Ringba publisher/sub-ID
• Call conversion → Ringba
• Conversion + affiliate ID → Everflow via server postback

That means you can credit Affiliate 123 with a $50 qualified call even if there isn't a traditional browser click immediately preceding the call. helpdesk.everflow.io

Invoca is the other serious option

Invoca is more enterprise-oriented and has sophisticated call attribution, including partner/affiliate attribution and pay-per-call functionality. It also has a direct Everflow integration for synchronizing offer and affiliate data and importing call tracking data. www.invoca.com

So I'd roughly choose:

Ringba + Everflow → if you're building/managing an affiliate or pay-per-call program.

Invoca + Everflow → if you're an enterprise advertiser with complex call-center attribution and a larger budget.

Ringba + Voluum → if you're primarily an affiliate/media buyer and already use Voluum. Ringba has a documented integration that sends inbound calls as conversions to Voluum. support.ringba.com

If you tell me how your affiliates send traffic (unique URLs, coupon codes, dedicated phone numbers, etc.) and whether you're paying per call, per qualified call, or per sale, I can map out the exact tracking architecture and recommend the simplest stack.

Yes. If the goal is “affiliate clicks → affiliate ID → phone call → qualified/converted call → commission”, you want a platform that can preserve an affiliate/subID through the click and attach it to the resulting call.

Best fits

My first choice for an affiliate program would be Ringba. It was specifically built around performance marketing and pay-per-call, with partner management, call routing, campaign tracking, URL parameters, attribution, webhooks/API, and real-time reporting. www.ringba.com

Invoca is the other serious option if you're an enterprise advertiser/network. It explicitly supports pay-per-call programs and managing partners, campaigns, payouts, and call-conversion data. www.invoca.com

How I'd structure it

For example, your affiliate sends:

https://yourdomain.com/offer?affiliate_id=12345&sub_id=abc789

Your tracking system stores:

affiliate_id = 12345
sub_id       = abc789

The visitor then calls a dynamically assigned tracking number. The call record retains the affiliate/sub ID:

Affiliate 12345
   ↓
Click
   ↓
Landing page
   ↓
Tracking number
   ↓
Phone call
   ↓
Call qualified = YES
   ↓
Conversion
   ↓
Commission = $75

You can then send the conversion back to the affiliate platform via postback/webhook/API, so the affiliate gets credited just as they would for an online conversion.

One important distinction

If you're running an affiliate program where many affiliates send traffic to your website, I'd lean Ringba + your affiliate platform.

If you're a pay-per-call network that actually buys/sells calls and needs routing, buyers, sellers, caps, payouts, and call qualification, Ringba or Invoca becomes much more compelling. Ringba specifically advertises automated partner management, routing/capping/financial rules, and pay-per-call functionality. www.ringba.com

If you tell me what affiliate software you're currently using (Impact, Everflow, TUNE, CAKE, PartnerStack, custom, etc.) and whether the conversion is “any call,” “call > X minutes,” or “sale made during the call,” I can map out the exact setup and recommend the best combination.

Yes. If your requirement is specifically “affiliate clicks → unique tracking context/affiliate ID → phone call → qualified/conversion event → affiliate payout/postback,” there are a few platforms that are much better suited than generic call-tracking tools.

Best fits

My first choice for an affiliate-heavy operation would be Phonexa. Its call-tracking product explicitly supports an affiliate view, publisher-level metrics, billable call duration, and server-to-server postbacks to an affiliate network/CRM after a call's outcome is determined. phonexa.com

Invoca is another strong option, particularly if you're operating at enterprise scale. Its pay-per-call product is designed around networks, publishers, advertisers and payouts, and it supports integrations with affiliate/performance-marketing platforms including CJ and TUNE. www.invoca.comphonexa.com

The architecture I'd recommend

For example, an affiliate sends someone to:

https://yourdomain.com/offer?aff_id=12345

Your tracking system stores:

aff_id = 12345
click_id = abc789

The visitor gets a dynamically assigned phone number:

1-800-555-1234

When they call:

Call
 ↓
Tracking platform identifies affiliate/click
 ↓
Call is routed to your sales team/buyer
 ↓
Call meets conversion criteria
   (e.g. ≥ 90 seconds, answered, sale made)
 ↓
Conversion recorded against aff_id=12345
 ↓
S2S postback to affiliate platform
 ↓
Affiliate gets credited

The important part is not simply having a tracking number. You want the platform to preserve the affiliate/click ID through the call and then fire a server-side conversion/postback. Phonexa explicitly supports this workflow. phonexa.com

One important distinction

If you're an advertiser with a handful of affiliates, I'd look at Retreaver / Invoca / CallTrackingMetrics.

If you're running an affiliate network or pay-per-call marketplace, I'd put Phonexa and Invoca at the top of the list because they are designed around publishers, buyers, call distribution, qualification, and payouts—not just marketing call analytics. www.invoca.comphonexa.com

If you tell me what affiliate software/network you're currently using (e.g. Everflow, TUNE, Impact, CAKE, HasOffers/Trackdesk, custom, etc.), I can narrow this down to the 2–3 systems that can actually pass your affiliate ID through to a phone conversion and fire the conversion back automatically.

Yes. For affiliate-driven phone conversions, you usually want a call tracking + affiliate attribution platform, not just a basic marketing call tracker. The key features to look for are:

• Affiliate ID / publisher ID passed into the tracking URL
• Unique tracking numbers or dynamic number insertion (DNI)
• Call-level attribution (who generated the call)
• Conversion rules (e.g., answered > 90 seconds, qualified lead, sale)
• S2S postbacks/API to send conversions back to your affiliate platform
• Fraud detection and duplicate call handling

Good options:

Typical affiliate call tracking setup

1. Affiliate sends traffic:

yourdomain.com/?aff_id=12345&sub_id=abc

2. Tracking platform stores:

Affiliate ID: 12345
Sub ID: abc
Campaign: Auto Insurance
Landing page: /quote

3. Visitor sees a unique phone number.

4. Customer calls.

5. Platform records:

Call ID: 987654
Affiliate: 12345
Duration: 4:32
Qualified: Yes
Payout: $35

6. Platform sends a conversion back:

POST /affiliate/postback?
aff_id=12345&
conversion_id=987654&
payout=35

My shortlist by use case

• Running a true affiliate/pay-per-call program: Phonexa or Ringba
• You have many affiliates and need routing/buyer management: Ringba or Phonexa
• You are an advertiser buying affiliate traffic: Invoca or CallTrackingMetrics
• You only need basic affiliate source attribution: CallRail may be enough

If you already use an affiliate platform such as Everflow, Impact.com, TUNE, or CAKE by Accelerize, the best choice depends on whether you need the call tracker to be the affiliate system of record or just send call conversions back into it.

If your goal is to attribute phone calls to individual affiliates, you need a platform that combines:

• Dynamic phone number insertion (DNI)
• Affiliate click tracking (via affiliate ID, subID, click ID, etc.)
• Call attribution back to the affiliate
• API or webhook integrations with your affiliate platform and CRM

Here are some of the strongest options:

Top recommendations

1. Ringba

Probably the most popular in the affiliate/pay-per-call world.

Pros:

• Tracks affiliate IDs, sub IDs, click IDs
• Pools of tracking numbers
• Real-time reporting
• Fraud detection
• Payout calculations
• APIs and webhooks
• Designed specifically for pay-per-call campaigns

Best if you're paying affiliates based on qualified calls.

2. Retreaver

Another platform built around affiliate and performance marketing.

Features:

• URL parameter tracking
• Session attribution
• Dynamic number replacement
• Affiliate routing
• Call qualification rules
• Conversion events
• CRM integrations

Many affiliate networks use Retreaver.

3. CallRail

If your affiliate program isn't extremely large.

Typical flow:

Affiliate sends:

https://example.com/?affiliate_id=12345

CallRail stores:

• affiliate_id
• utm_source
• gclid
• landing page
• visitor session

When the visitor calls:

Call
   ↓
Tracking Number
   ↓
Conversion
   ↓
affiliate_id = 12345

Very easy to set up.

4. CallTrackingMetrics

Excellent if you need:

• calls
• forms
• chats
• SMS
• CRM syncing

Can attribute everything back to URL parameters like:

affiliate_id
partner
subid
clickid
offer
campaign

5. Invoca

More enterprise-focused.

Good if you have:

• thousands of calls/day
• Salesforce
• enterprise affiliate programs
• AI conversation scoring
• revenue attribution

Usually more expensive.

How attribution typically works

An affiliate sends traffic such as:

example.com/?aff_id=812&subid=facebook_ad3

The tracking software:

1. Reads the URL parameters.
2. Stores them in the visitor session.
3. Displays a unique tracking phone number.
4. When the visitor calls, the software associates the call with:
   • Affiliate ID
   • Sub ID
   • Campaign
   • Landing page
   • Keyword (if applicable)
   • Revenue or qualified-call status

The resulting record might look like:

Call ID: 98273
Affiliate: 812
Sub ID: facebook_ad3
Duration: 7m 42s
Qualified: Yes
Sale Amount: $420
Commission: $84

If you're running your own affiliate software

Most call-tracking platforms can capture custom URL parameters, including:

• affiliate_id
• affiliate
• partner_id
• subid
• subid1
• subid2
• clickid
• transaction_id

This makes them compatible with many affiliate systems without requiring a native integration.

Recommendation by scale

• Small to medium affiliate program (up to ~100 affiliates): CallRail or CallTrackingMetrics.
• Affiliate network or pay-per-call business: Ringba or Retreaver.
• Enterprise with high call volume and advanced analytics: Invoca.
• All-in-one performance marketing platform (affiliate management plus call tracking): Phonexa.

If you can share:

• approximately how many affiliates you have,
• expected monthly call volume,
• whether you already use an affiliate platform (e.g., Post Affiliate Pro, Everflow, Impact, PartnerStack, Tune/HasOffers, or a custom solution),
• and whether commissions are based on every call or only qualified/sales calls,

I can narrow the list to the best fit and outline the integration approach.

If your goal is to attribute phone call conversions back to individual affiliates, you'll want a platform that combines dynamic call tracking with affiliate parameter capture (such as affiliate_id, subid, click_id, or UTM parameters).

The best options depend on your affiliate platform and call volume.

1. CallRail

Good if you're already running web-based affiliate traffic.

How it works:

• Affiliate sends traffic to:

  yoursite.com/?affiliate_id=12345

• CallRail reads the URL parameter.
• Visitor sees a unique tracking number.
• If they call:
  • affiliate_id
  • landing page
  • campaign
  • keyword
  • UTMs

are stored with the call.

Pros:

• Easy setup
• Good reporting
• Affordable
• Zapier support

2. Ringba (one of the strongest choices)

Ringba was designed around pay-per-call marketing.

Features:

• Per-affiliate routing
• Track publisher IDs
• Pass click IDs
• IVR
• Real-time payouts
• Fraud detection
• Call quality scoring

If affiliates are primarily driving phone calls, Ringba is often one of the strongest fits.

3. Retreaver

Very popular with lead generation companies.

Supports:

• affiliate_id
• publisher_id
• subid
• clickid
• Google Click ID (GCLID)
• Meta Click ID (FBCLID)

You can trigger conversions only after:

• minimum call duration
• qualified caller
• sales outcome
• custom webhook

4. Invoca

Enterprise-level solution.

Useful if you have:

• multiple brands
• thousands of calls
• call centers
• Salesforce
• Adobe
• enterprise analytics

It can attribute revenue back to affiliates and campaigns.

5. CallTrackingMetrics

Very flexible.

Supports:

• Dynamic Number Insertion (DNI)
• URL parameter capture
• Custom fields
• API
• Call scoring
• CRM sync

Works well when you need marketing attribution across affiliates, paid search, and organic traffic.

Typical implementation

1. Affiliate link:

https://example.com/?affiliate_id=8472

2. Visitor lands.

3. Call tracking script:
4. saves affiliate_id
5. assigns a tracking number

4. Visitor calls.

5. Call record contains:

Affiliate: 8472
Campaign: Summer2026
Landing Page: /insurance
Duration: 11m 42s
Recording: Yes
Qualified: Yes
Sale Amount: $850

6. The call tracking platform sends the conversion to:
7. Affiliate platform
8. CRM
9. Reporting dashboard
10. Billing system

If you're using an affiliate platform

Many affiliate platforms can work with these call tracking systems through APIs, webhooks, or automation. Examples include:

• Everflow
• Trackdesk
• Post Affiliate Pro
• TUNE
• Impact.com

The affiliate platform passes a unique click or affiliate identifier to your site, and the call tracking platform stores that identifier with the call. When a call qualifies as a conversion, the tracking platform can send the conversion back so the correct affiliate receives credit.

My recommendation by use case

• Small to midsize business: CallRail for ease of setup and solid attribution.
• Affiliate-heavy lead generation or pay-per-call: Ringba or Retreaver, as they're designed specifically for affiliate and publisher attribution.
• Enterprise marketing teams: Invoca for advanced attribution and analytics.
• Agencies or businesses needing broad marketing attribution: CallTrackingMetrics.

If you can share:

• your affiliate software (e.g. Everflow, Impact, Trackdesk, TUNE, custom),
• your phone provider (Twilio, RingCentral, etc.), and
• whether affiliates send traffic to your website or directly to a phone number,

I can recommend the simplest integration architecture for your setup.

If you want to attribute phone call conversions back to individual affiliates, you generally need three capabilities working together:

1. Dynamic call tracking (unique phone numbers shown to visitors)
2. Affiliate click tracking (affiliate ID, subID, click ID)
3. Passing the affiliate identifier into the call record so the conversion can be attributed.

There are several platforms that support this well.

How it usually works

An affiliate sends traffic like:

https://example.com/?aff_id=247&subid=facebook_ad1

The call tracking software:

• stores aff_id=247
• stores the subID/click ID
• swaps the displayed phone number with a unique tracking number
• when the visitor calls, the software associates the call with:
  • affiliate 247
  • campaign
  • landing page
  • keywords (if applicable)
  • revenue
  • recording

Then you can pay commissions based on completed calls.

If you already have an affiliate platform

Many affiliate systems don't do call tracking themselves, but they integrate well.

Examples include:

• Everflow
• TUNE
• Impact.com
• Post Affiliate Pro

A common setup is:

Affiliate
      ↓
Affiliate software
      ↓
Landing page (?aff_id=247)
      ↓
Call tracking platform
      ↓
Phone call
      ↓
Conversion
      ↓
Webhook/API back to affiliate software

Best choices by use case

• General affiliate program: CallRail or CallTrackingMetrics
• High-volume pay-per-call: Ringba or Retreaver
• Enterprise with Salesforce/HubSpot: Invoca
• Lead generation company: Phonexa
• Need to pay affiliates based on qualified calls: Ringba is particularly strong because it was designed around affiliate and pay-per-call workflows.

If you're handling hundreds or thousands of affiliate calls per month, Ringba and Retreaver are typically the strongest options because they support:

• affiliate IDs and subIDs
• real-time call routing
• payout rules
• fraud detection
• postback/webhook integrations
• buyer routing
• detailed reporting by affiliate and campaign

If you can share which affiliate platform you're using (for example, Everflow, Impact, TUNE, Post Affiliate Pro, Rewardful, or a custom system), I can recommend the simplest integration and outline the data flow.

If you want to attribute phone call conversions back to individual affiliates, you need software that combines call tracking with dynamic phone numbers and the ability to pass an affiliate ID (or click ID) through the visitor journey.

The best options depend on whether you're running your own affiliate program or using an affiliate network.

How it typically works

1. Affiliate sends traffic to:

   yoursite.com/?affid=12345

or

   ?affiliate_id=12345

2. The call tracking software:
   • Stores the affiliate ID in a cookie/session.
   • Replaces the phone number on the website with a tracking number (Dynamic Number Insertion).
   • When the visitor calls, it associates that tracking number with the stored affiliate ID.
   • The call is logged as:

     Affiliate 12345
        ↓
     Visitor
        ↓
     Phone Call
        ↓
     Qualified Call
        ↓
     Sale

3. The platform can then:
   • report calls by affiliate
   • report revenue by affiliate
   • send conversions back to your affiliate platform via API or postback

If you're already using an affiliate platform

Many affiliate systems can receive phone conversions:

• Everflow
• Trackier
• TUNE
• Impact.com

These are commonly integrated with Ringba, CallTrackingMetrics, Invoca, or CallRail so phone conversions appear alongside online conversions.

If you're running a pay-per-call affiliate program

The industry standards are:

1. Ringba
2. Retreaver
3. Phonexa

They support:

• affiliate IDs
• sub IDs (SubID, ClickID, etc.)
• IVR routing
• call qualification (minimum duration)
• payouts by affiliate
• fraud detection
• API/webhooks

If you're only tracking calls from your own website

A simpler setup is often enough:

• CallRail
• CallTrackingMetrics

Pass the affiliate ID as a URL parameter, store it in a cookie, and configure the platform to capture that value as a custom field so every inbound call is attributed to the correct affiliate.

If you're building or managing your own affiliate program and expect significant call volume, Ringba or CallTrackingMetrics are often the strongest choices because they're designed to preserve affiliate attribution through to the phone call and support automated conversion reporting.

Yes. What you need is call tracking with dynamic number insertion (DNI) combined with affiliate click IDs (subID, aff_sub, click_id, etc.). The call tracking platform captures the affiliate ID from the landing URL, stores it in the visitor session, swaps in a unique phone number, and attributes any resulting call back to that affiliate.

A typical flow looks like this:

Affiliate Link
   ↓
https://yoursite.com/?aff_id=123&click_id=abc123
   ↓
Call tracking script stores aff_id + click_id
   ↓
Dynamic phone number displayed
   ↓
Customer calls
   ↓
Call attributed to affiliate 123
   ↓
Webhook/API sends conversion back to affiliate platform

Here are the strongest options:

Community recommendations consistently put CallRail, CallTrackingMetrics, and WhatConverts among the easiest solutions for tying calls back to marketing parameters like UTMs and click IDs. www.reddit.com

If you're running an affiliate program

The ideal setup is:

1. Affiliate platform generates:

   ?affiliate_id=45
   ?click_id=8fj39f

2. Call tracker stores those values.

3. When a phone call occurs:
   • duration
   • caller
   • recording
   • affiliate_id
   • click_id
   • campaign

4. The call tracker sends a webhook to your affiliate platform:

   {
     "affiliate_id":45,
     "click_id":"8fj39f",
     "conversion":"phone_call",
     "qualified":true,
     "value":250
   }

This lets you pay affiliates only for qualified calls or sales.

If you use affiliate software

Most modern affiliate platforms support this via APIs or postbacks:

• Everflow
• TUNE
• Impact
• PartnerStack
• Tapfiliate
• FirstPromoter

The call tracking system becomes the source of truth for the phone conversion and reports it back to the affiliate platform.

My recommendation

• Small to medium affiliate program: CallRail
• Serious affiliate network with custom rules and payouts: CallTrackingMetrics
• Need both form and phone attribution in one dashboard: WhatConverts

One important question

Are your affiliates sending traffic to:

• your own website (where you control the landing page and phone number), or
• a unique phone number directly (pay-per-call style)?

The best architecture is different depending on whether you're tracking web → phone or phone-only affiliate campaigns.
