About this API
WorkOS is a B2B SaaS infrastructure company founded 2019, very specifically positioned: "let SaaS support enterprise customer SAML SSO in hours". Background: when B2B SaaS sells to enterprise customers, enterprise IT will demand SAML SSO (employees use company Okta / Azure AD to log into SaaS, not separate accounts). But SAML protocol is complex, every enterprise IdP configures differently, debugging is painful; traditional SaaS teams spend months hitting pitfalls. WorkOS bundles all this into APIs: your SaaS integrates WorkOS SDK, adds 5 lines of code, supports all major IdPs (Okta / Azure AD / Google Workspace / OneLogin). Companion products: SCIM directory sync (customer HR system auto-provisions / deprovisions users), Audit Logs (enterprise compliance), Magic Link, Admin Portal. Free 1M MAU SSO is industry-most-generous. Customers mainly SaaS companies expanding to enterprise market (Vercel, Linear, PlanetScale all use).
