+## Supported features
+
+Flagsmith's SCIM 2.0 API supports:
+
+- Creating users.
+- Deleting users. See [User lifecycle](#user-lifecycle) for what is and is not removed.
+- Pushing groups: create and update [permission groups](/administration-and-security/access-control/rbac#groups) and
+  their membership, and delete groups.
+- Filtering and pagination on the `/Users` and `/Groups` list endpoints.
+
+Flagsmith does not support:
+
+- Deactivating users through the `active` attribute. Use DELETE requests to deprovision users instead.
+- Profile sourcing, `/Me`, `/Bulk`, sorting, and ETag concurrency control.
