## Other responses

- `400`: Bad Request: a missing or invalid parameter, or a change that is not allowed (error_code says which).
- `401`: Unauthorized: the api_key is missing or invalid, or API access is not enabled for the workspace.
- `404`: Not Found: no object with that id in your workspace, or an unknown URL or method.
- `409`: Conflict: idempotency_key_in_use (a request with the same Idempotency-Key is still being processed; retry after a moment with the same key) or idempotency_key_indeterminate (an earlier request with that key did not finish; check whether it succeeded, then retry with a new key).
- `429`: Too Many Requests: the rate limit was exceeded.
- `500`: Unexpected Internal Error.
