Hello,
The Google Ads API Beta will continue to function, and we will continue to do releases on that API, but we are just not recommending it for production usage. So, there is no timeline for rolling anything back. 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.
Let me know if you have any questions.
Thanks,
Bharani, Google Ads API Team
