Explainer

A 401 Unauthorized response indicates the Marketing Cloud API rejected the request because the access token is missing, invalid, or expired. Developers must resolve this by verifying the request header and obtaining a new valid access token through the authentication service.

Core information
  • A 401 status code explicitly signals that the access token in the request header is missing, invalid, or expired.
More details and nuances
  • Legacy package integrations use the requestToken endpoint where tokens expire after one hour.
