Manage Claude Enterprise Seats Programmatically: Admin API User Management Now in Beta

TL;DR: Claude Enterprise admins can now manage seats, roles, and groups via REST API — enabling IdP-synced onboarding and offboarding without touching the admin panel.

Anthropic released user management endpoints to the Admin API this week, in beta for all Claude Enterprise organizations. The new endpoints let you:

• List organization members and look them up by email address
• Change a member's role (e.g. Member → Admin)
• Remove members and withdraw pending invitations
• Create and manage groups and their membership
• Read custom role definitions

Group and custom-role operations require the beta header anthropic-beta: ce-user-management-2026-07-13. Member and invite endpoints work with any Admin API key that has the read:org_audit scope.

Why it matters: This makes Claude Enterprise automatable. Teams can now hook seat provisioning into an IdP (Okta, Entra ID, etc.) so new hires get Claude access on day one and departing employees lose it automatically — no manual admin portal steps, no access-review spreadsheets.
