SCIM (System for Cross-domain Identity Management)

SCIM is an open standard for automatically provisioning and deprovisioning user accounts between an identity provider (like Okta or Entra ID) and your SaaS app. When an enterprise admin adds an employee in their directory, SCIM pushes that user into your product automatically; when someone leaves, SCIM removes their access — no manual account management, no orphaned logins. Alongside SSO, SCIM is a core "enterprise-readiness" checkbox: large customers won't buy a tool they can't manage at scale or offboard instantly for security and compliance reasons. For builders, supporting SCIM (a REST API with standard schemas for users and groups) is often what unlocks moving upmarket from self-serve to five- and six-figure contracts. It's frequently bundled behind an "enterprise plan," making it both a security feature and a monetization lever. Expect to implement it once you start selling to companies with dedicated IT and hundreds of seats.
