Hello Jesus,
We do not have client libraries for Go language. If you are facing any issues related to that library you could file an issue on their
issue tracker. Google Ads API beta has the client libraries and examples available in the programming languages specified
here. You could choose the language of your choice among them and setup the client library using the README file present in each client library. To generate OAuth credentials, you could follow
this guide and to create refresh token refer
this guide.
Also, Irrespective to the client library, you could make API calls to the Google Ads API beta via the CURL requests mentioned
here. Please let me know if you have any further questions.
Regards,
Sai Teja, Google Ads API Team
