Hi,

Thanks for reaching out to the Google Ads API Forum.

Upon checking logs, I can see that you’ve encountered AUTHENTICATION_ERROR, however, could you please double check if you’re sending the correct developer token for your API request? If you’re indeed sending the exact same developer token that was copied from MCC account’s API center, and still encountering it, then I request you may provide us with the complete logs in the format of the request and response logs along with the request-id without redacting, as seen in their respective links.

For you to enable complete logs on your end for the client library, logging can be enabled by navigating to the Client libraries > Your client library (ex Java) > Logging documentation, which you can access from this link here https://developers.google.com/google-ads/api/docs/client-libs. Kindly provide the requested details using reply privately to the author option.

• response - https://developers.google.com/google-ads/api/docs/concepts/field-service#response

 

This message is in relation to case "ref:_00D1U1174p._5004Q2lvyqr:ref"

Thanks,
