I'm trying to activate the Google Ads Api for my Google Cloud project. But every time I try it throws the following error:
An unknown error occurred when attempting to verify your billing information. Please try again or return later
Tracking number: NUMBER
I was able to activate other APIs normally. Contacted the billing support and they didn't find any billing problem. Google Ads API support is offline.
Any ideas on how to solve it or how to get help? :)
