Hi all,

I am getting the following error: 

''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.'

I am using a developer token, client secret, client id and developer token, so not sure what more it needs.

Thanks,

Katherine

I've started seeing this sporadically as well over the last 24-36 hours.  I've been on the Ads API v10 for several weeks now with zero authentication issues.  This error just stated popping up yesterday randomly on a very tiny number of requests.

Hi Katherine,

Thanks for reaching out to the Google Ads API Forum.

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

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. 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,

Yasar Google Ads API Team
