Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential

[Thien Tran]

Hi, 

I'm using Google Ads Api and follow this document https://developers.google.com/google-ads/api/docs/start. But i got the authentication failed issue.

{ "message": "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https:\/\/developers.google.com\/identity\/sign-in\/web\/devconsole-project.", "code": 16, "status": "UNAUTHENTICATED", "details": [ { "@type": "google.ads.googleads.v6.errors.googleadsfailure-bin", "data": "<Unknown Binary Data>" }, { "@type": "grpc-status-details-bin", "data": "<Unknown Binary Data>" }, { "@type": "request-id", "data": "feAcN0Pr2ap5iWrpDaC-rA" } ] }

Here is my code for making first call

I'm sure the refresh token and access token are generated correctly because I tried to use them in another service and it works fine

How can I resolve it?

Thanks,

Hi,

Thanks for reaching out to us.

Could you provide us with the complete request and response logs with the request-id, so our team can better check?

If you haven't yet, logging can be enabled by navigating to the Client libraries > Your client library (ex. Java) > Logging documentation, which you can access from this link. You may then send the requested information via the Reply privately to author option. If this option is not available, you may send the details directly to our googleadsa...@google.com alias instead.

Regards,
