## Other responses

- `400` — Strict-body violation or no editable field supplied (at least one of `defaultSenderName` / `defaultFromEmail` / `defaultReplyToEmail`).
- `401` — The API key was missing, invalid, or revoked.
- `403` — The caller does not have the required `domains` permission.
- `404` — Domain not found in the API-key brand. Cross-brand ids intentionally surface as 404 (never 403) so the API does not leak cross-brand existence.
