fields) to the list of rules it broke. Fix every listed field before retrying.

Example: {"code": "VALIDATION_ERROR", "message": "There have been validation errors", "details": {"email": [{"code": "MISSING_REQUIRED_FIELD", "message": "email is required"}]}}

The request has no valid access token. Get a new token from POST /login and send it as Authorization: Bearer <token>.

Codes: UNAUTHORIZED_NO_TOKEN (no Authorization header), UNAUTHORIZED_INVALID_TOKEN (expired or malformed token),
UNAUTHORIZED_NO_CONTEXT (the token does not belong to a payor or merchant), UNAUTHORIZED_NO_PAYOR (the token gives access
to more than one payor and the request did not send x-payor-id). A few endpoints answer from the API gateway instead and
return only {"message": "Unauthorized"}.

Codes: FORBIDDEN_INSUFFICIENT_TAGS (your credential's role does not allow this operation), FORBIDDEN_CONDITION_NOT_MET
