A 401 and a 403 look similar in an automation screen but represent different checks. A 401 usually means the server did not receive valid authentication: a missing or expired token, or credentials sent in the wrong header. A 403 means authentication arrived, but the connected identity is not permitted to perform the requested action or use the resource.
Start with a request log: endpoint without secrets, HTTP method, response code, connection or user ID, time, and shortened response. Check that the key belongs to the right workspace, that the user is still active, and that its role includes the action. Never paste an API key into a screenshot or ticket note.
Do not repeatedly retry a financial action before understanding the error. Duplicate calls can create duplicate documents or records if the interface does not support idempotency. After renewing access, test a read-only action first, then restore the missing business action.
