Google Ads API v25 released with loyalty retention goals, Shorts social metrics and unified goals schema

v25 added the ad_sub_format_type segment for non-skippable YouTube ad durations, comments/likes/shares metrics for Shorts ads, a loyalty retention goal, a revamped new customer acquisition goal using Goal and CampaignGoalConfig (removing CustomerLifecycleGoal and CampaignLifecycleGoal), and consented YouTube channel insights, and made synthetic content attestation fields mutable.

Breaking changes per release notes: lifecycle goal resources and services removed (migrate to the unified goals schema); Incentive Service type fields replaced with standalone enum fields; deprecated Planning Service fields search_brand and plannable_location_id removed. Also added YouTube third-party conversion attribution and animated image generation for Demand Gen. v25 sunset: August 2027.
