SCIM (System for Cross-domain Identity Management) is the open standard for automatically provisioning user accounts across applications. When someone joins, moves team or leaves in your identity provider, SCIM creates, updates or deactivates their accounts everywhere downstream.
For workplace platforms it removes the two failure modes IT cares about: new starters who cannot book a desk on day one, and leavers whose accounts quietly live on. Paired with SSO, it makes the workplace app zero-admin for IT.
