The image below is the state of Link is returned when you do not provide the correct credentials, I.E., there is a mismatch of clientId and the token OR the token has expired. If this occurs, you must confirm that you are authenticating the correct clientId associated with the API Key and the Secret Key. If this authentication information is correct, it could also be that your Link token is no longer valid, and you will need to reauthenticate to retrieve a valid token session.
