Announcing expanded experiment functionality in Google Ads API v24.1

We are excited to announce a significant expansion of the Google Ads A/B experiments feature set in the v24.1 release , launched yesterday, May 13, 2026. We know API functionality is critical for advertisers who manage large sophisticated accounts, and we want to give these advertisers the capability to better create and manage their A/B experiments at scale. This update broadens the platform’s current scope, enabling advertisers to leverage the power of experiments for a broader range of testing scenarios to drive campaign performance.
