## Other responses

- `400`: Validation failed — `error` names each offending field (`field: message`).
- `401`: Missing, malformed or unknown credentials (`WWW-Authenticate: Bearer …` is set).
- `403`: The credential lacks the `notifications:manage` scope (body `{ error: "insufficient_scope", required, missing }`), or the team is suspended.
- `404`: Channel, domain or mailbox not found.
- `429`: Rate limited (60/min). `Retry-After` gives the seconds to wait; `X-RateLimit-*` headers are sent on every response.
