Does google ads API work?
When I click the google ads API document, I get "Service Unavailable".
Thank you so much!
You can view the Google Ads API status here: https://ads.google.com/status#hl=en&v=status
Yes you can create custom audiences in Google Ads API, see documentation here: https://developers.google.com/google-ads/api/docs/remarketing/audience-types/custom-audiences
Yes, I have had experience using this attached one: https://github.com/Opteo/google-ads-api . I used it for GAQL queries and a few bid change things and it worked good. It is not as documented as Python's Client Library.
Lemme know if you have any other questions, hope this helps.
