Outbound
Get an Outbound mutation status
For requests that included an idempotencyKey, use the Outbound-Operation-Id response header or the ID in an operation conflict. Unkeyed requests do not create operation receipts. Operations are scoped to the workspace and initiating admin. Completed/failed records remain for at least 7 days. Unknown outcomes never automatically expire or execute again: inspect the target message and coordinate recovery before a new mutation key. This endpoint does not return recipient data.
