Create a Group

Creates a Group in the selected Workspace from a name and an optional list of member Principal ids (at most 10,000, no duplicates). Assign a Group access once, then manage its membership without rewriting every PermissionAssignment. Accepts an Idempotency-Key so a retried create returns the original Group. Returns the created Group; use its id as a PermissionAssignment subject of kind group.

Checkfu support posture: alpha; hosted. Required evidence journey: identity-tenancy. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.
