Hi Olesya,
Thank you for reaching out. Google Ads API is still in beta version. We don’t have a set timeline for the Google Ads API to be in production again. However, We recommend to continue running production systems using the AdWords API. While Google Ads API is in “beta”, you may use the new API for testing and development work in preparation for future migration. Please keep in mind that during this "beta" phase, there may be breaking changes in the Google Ads API. You could keep an eye on our blog for updates on new releases.
Thanks and regards,
Xiaoming, Google Ads API Team
