Google has recently announced that to pull back Google Ads API into its beta version. They launched Google Ads API in March 2019 into a production environment.
Your feedback about the performance of our products is very important to us. After launching the Google Ads API in March, we’ve heard feedback about slow response times compared to the AdWords API. After in-depth analysis, we’ve determined that the overall performance of the Google Ads API is not ready for production usage.
We take performance very seriously, and this is our highest priority to address. In the meantime, we’re reverting Google Ads API back to beta status and recommend production systems to use AdWords API for the best experience.Google
