google_ads_ads_update
Update the creative copy of a Responsive Search Ad by replacing headlines or descriptions while preserving omitted assets. Records before-state for rollback support.
Instructions
Updates the creative copy of an existing Responsive Search Ad by replacing headlines and/or descriptions. A supplied side is fully replaced (Google has no per-asset patch); omit a side to leave it unchanged — the omitted side is read from the current ad and preserved, so updating headlines never wipes 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 — not automatically reversible; record before-state with mureo_state_action_log_append if you may need to roll back. For status-only changes (pause/resume) use google_ads_ads_update_status, which is lighter-weight and does not reset learning.

| customer_id | No | Google Ads customer ID as a 10-digit string without dashes (e.g. '1234567890'). Optional — falls back to GOOGLE_ADS_CUSTOMER_ID / GOOGLE_ADS_LOGIN_CUSTOMER_ID from the configured credentials when omitted. | |
