Errors
Errors and error codes Live
Every failure uses the same envelope: a stable code, a human message, and a request id.
Full reference: API · Errors — envelope, status classes and client behaviour from 400 through 504.
- Stable codes are part of the public contract; message copy is not.
- 409 conflicts usually mean a duplicate under idempotency — re-read rather than re-send.
- Quote the request id in support conversations; it is the correlation key operators search for.
