gads_update_rsa
Google Ads tool (extended/low-level coverage). For common tasks prefer the RECOMMENDED google_ads_* actions; use these only for advanced operations those don't cover. Replace headlines and/or descriptions of an existing Responsive Search Ad (RSA). Replaces the entire headlines or descriptions list. To add a single asset without removing existing ones, use gads_add_rsa_asset instead. Args: ad_id: ID of the ad to update (required). ad_group_id: Ad group ID that contains the ad (required). headlines: New list of headline strings (3–15 items, max 30 chars each). Replaces all existing headlines. descriptions: New list of description strings (2–4 items, max 90 chars each). Replaces all existing descriptions. customer_id: Google Ads customer ID. Leave blank to use default.
