Data Manager API reached general availability as Google's unified first-party data ingestion API

The Data Manager API became generally available for sending audience (Customer Match, mobile IDs, PAIR) and conversion data once to Google Ads and Display & Video 360, with confidential matching and encrypted identifiers. During 2026 Google made it the primary import path, closing the Google Ads API to new adopters of IP/session attributes, Customer Match and offline conversion imports.

Later Data Manager API milestones: v1.5 (Feb 17, 2026) added UserListService lifecycle management, PartnerLinkService and User ID identifiers; May 7, 2026 added Google Ads store sales conversions and GA web/app event ingestion; May 28, 2026 added GMP (CM360/SA360/DV360) conversion destinations and IP ingestion for Customer Match via CompositeData; July 30, 2026 added RemoveAllAudienceMembers, field-level ingestion warnings and expanded address data.
