# SCIM API **(PREMIUM SAAS)**

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/98354) in GitLab 15.5.

GitLab provides an SCIM API that both implements [the RFC7644 protocol](https://www.rfc-editor.org/rfc/rfc7644)
and provides the `/Users` endpoint. The base URL is `/api/scim/v2/groups/:group_path/Users/`.

To use this API, [Group SSO](../user/group/saml_sso/index.md) must be enabled for the group.
This API is only in use where [SCIM for Group SSO](../user/group/saml_sso/scim_setup.md) is enabled. It's a prerequisite to the creation of SCIM identities.

Not to be confused with the [internal group SCIM API](../development/internal_api/index.md#group-scim-api).
