For a SaaS company onboarding external customers, I’d shortlist:
- LearnUpon — strong fit for customer education: REST API/webhooks for creating users and enrolling courses, SSO including SAML/OIDC, SCIM, and multi-portal support. LearnUpon LearnUpon Support LearnUpon
- Northpass — particularly developer-friendly, with APIs, webhooks, and OAuth/OIDC/SAML integration. Northpass Northpass
- Docebo — robust enterprise option with OAuth-based APIs and SSO, plus extensive integrations. Docebo Developer Portal Docebo Help
My starting point would be LearnUpon if your flow is: product signup → create customer/user → SSO → automatically assign training → track completion.
If you tell me whether you need B2B customer SSO (each customer's Okta/Entra) or simply your SaaS login → training, I can narrow this to 2–3 platforms.
