google_ads_callouts_create
Add a callout text to a Google Ads campaign by creating and linking the asset, respecting the maximum of 20 callouts per campaign.
Instructions
Create a callout Asset and link it to a Google Ads campaign in a two-step mutate (AssetService then CampaignAssetService). Returns {resource_name} of the newly created asset, or {error:true, error_type:'validation_error', message} when the campaign already has 20 callouts (_MAX_CALLOUTS_PER_CAMPAIGN limit). Mutating — reversible only by google_ads_callouts_remove. The asset is minted per call, so identical text creates duplicate asset rows. For sitelink variants use google_ads_sitelinks_create.
