v1 is superseded. v1 was superseded by v2 on 2026-08-26. A sunset date has not been announced yet; v1 will be deprecated as a whole before removal. Migrate with the v2 migration guide.

Parameters

Path Parameters

workspace_id

required

Workspace Id

Id of the workspace that owns the resource.

string format: uuid

Id of the workspace that owns the resource.

Header Parameters

Idempotency-Key

string

<= 255 characters

Opaque key making this request safe to retry. The first request with a given key executes; a later request with the same key returns that first response with Idempotent-Replayed: true instead of executing again. The key covers the method, path, query, and body it was first used with; reusing it for a different request is rejected with 422. Replayable for 24 hours.
