200

All lead task custom fields.

401

Invalid, revoked or expired token (401) — also returned when the connection was revoked or the company is blocked.

Produced by the authentication filter, so the body is a reduced envelope: no error, no requestId, and errors is null rather than []. Every cause yields the same fixed English message.

403

The token lacks the required permission:scope grant (403).

429

Rate limit of 60 requests/minute exceeded (429). Like 401, this comes from the authentication filter: reduced envelope, fixed English message, no error object and no Retry-After header.
