google_ads_ads_update
Replace headlines and descriptions of an existing Responsive Search Ad in Google Ads. Returns the updated ad. Resets learning and triggers re-review. For status-only changes, use the dedicated status update tool.
Instructions
Updates the creative copy of an existing Responsive Search Ad by replacing headlines and/or descriptions. Returns the updated ad. Google Ads does not support in-place edit of RSA creative assets — this call typically replaces the ad with a new one under the same ID, which resets learning and triggers re-review. Mutating, reversible via rollback_apply. For status-only changes (pause/resume) use google_ads_ads_update_status, which is lighter-weight and does not reset learning.
