## Other responses

- `400`: The request or return target is malformed or unsafe
- `401`: No valid credentials. WWW-Authenticate names the protected resource metadata to start from
- `403`: The credentials are valid but not enough: the token lacks the scope, or the action needs a browser session rather than an app token
- `404`: Not found
- `409`: The request id conflicts with an earlier attempt
- `429`: Rate limited. RateLimit names the policy; Retry-After says when to try again
- `500`: Internal server error
