Clearstream Xact User Management (SCIM 2.0)

The first business API Clearstream published on its API platform: User Management (SCIM2), an implementation of the SCIM 2.0 standard for provisioning, maintaining and monitoring Xact Web Portal users without logging into the GUI. It is served from the /scim2 prefix on api.clearstream.com and requires the OAuth scopes `allow` and `scim2-ext-v1` — confirmed by an unauthenticated GET to https://api-t2s-test.clearstream.com/scim2 that returned HTTP 403 naming both on 2026-09-05. Most calls additionally require the Xact SCIM Admin or SCIM Read-Only role on top of the Xact Web Portal User Management API role. The OpenAPI definition is published in the registration-gated Deutsche Borse Digital Business Platform catalogue.
