Authentication problems when migrating API AdWords to API ADS

[Victor P]

Hi,

I'm looking at migrating to API ads, but I'm having problems with authentication. The system with the ADWords API is working correctly, but when making the first call to API ADS launches the following error ( using the same refresh token ):

{ "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.v10.errors.googleadsfailure-bin", "data": "<Unknown Binary Data>" }, { "@type": "grpc-status-details-bin", "data": "<Unknown Binary Data>" }, { "@type": "request-id", "data": "5MsWzvm0tz3aO-C4UATbpA" } ] }

We do not understand why we can not make SearchStream queries (in red) but if we obtain access queries AccessibleCustomers (in blue):

 

Can someone know where the problem can be?

Thank you very much!

Hi Victor,

Thank you for providing more details to your concern.

Please check if your API environment was completely set up based on this document. If the error persists even though the API environment is completely set up, then please provide the user account / email address that you've used in authentication and the complete request and response logs with request ID and request header generated on your end to further investigate.

If you haven't enabled the logging of the API transactions for the specific client library that you are using, then please refer to the specific guide below:
Java - https://developers.google.com/google-ads/api/docs/client-libs/java/logging
.Net - https://developers.google.com/google-ads/api/docs/client-libs/dotnet/logging
PHP - https://developers.google.com/google-ads/api/docs/client-libs/php/logging
Python - https://developers.google.com/google-ads/api/docs/client-libs/python/logging
Ruby - https://developers.google.com/google-ads/api/docs/client-libs/ruby/logging
