Data Manager API adds RemoveAllAudienceMembers and warnings
Google released an update to the Data Manager API (2026-07-30) that introduces a RemoveAllAudienceMembers method to clear members from user lists (optionally scoped by timestamp), adds field-level ingestion warnings for validation issues on optional fields, and expands AddressInfo for Google Analytics events to include address_line, city, and administrative_area. The update clarifies that optional-field validation issues will produce field_warnings while required-field failures still follow a fast-fail model. The release also notes that the user_data field can satisfy identifier requirements for multi-source events sent to web data streams. Documentation links, integration guides, new Data Manager API agent skills on the Google Skills GitHub repository, and support/contact channels are provided in the announcement.
Technical release from a major platform (Google) that improves audience management, ingestion validation, and Analytics integrations — relevant to measurement, identity, and data workflows across AdTech.

Google Enhances Data Manager API for User List Management
Google announced v1.5 of the Data Manager API, adding end-to-end user list management and expanded audience ingestion options. The update introduces a UserListService that supports create, retrieve, update and delete operations for UserLists, and a PartnerLinkService to manage secure connections between advertiser and data partner accounts across Google Ads and Display & Video 360. Audience ingestion now accepts additional identifiers including User IDs for Customer Match, and diagnostics have been extended with status reporting specific to User ID ingestion. The blog post includes links to Customer Match and upgrade guides, Partner Link documentation, support contact information, and a partner interest form. The announcement was posted by Lindsey Volta on behalf of the Data Manager API Team.
Google Data Manager API Unifies Audience Management
Google published an Ads DevCast episode featuring Melissa Ng, Product Manager for the Data Manager API, introducing the Data Manager API as a unified ingestion point for audience and conversion data across Google advertising products. The API lets partners, agencies and advertisers send first-party data to multiple Google ad products (Google Ads, Display & Video 360, Campaign Manager 360, Google Analytics and others) in a single call, standardizing field schemas across downstream use cases. Google highlights privacy-by-default confidential matching using a Trusted Execution Environment (TEE), forthcoming Ads UI diagnostics for API health, and migration guidance. Early partner results cited include Treasure Data reporting 2x faster advertiser onboarding and an 80% reduction in engineering effort; a joint case study noted an advertiser spent over $1M annually on maintenance prior to migration.
Data Manager API Adds Store Sales and Analytics Event Support
Google announced enhancements to the Data Manager API on May 7, 2026. The update adds a streamlined ingestion workflow for uploading store sales conversions to Google Ads (including confidential matching, encryption for user identifiers, and multi-item CartData support) and expands support for sending events to Google Analytics web and app data streams. The API can now send any non-reserved event to web and app streams as an alternative to Measurement Protocol, supports richer metadata (app instance ID, event location, mobile device info), and enables event routing via Firebase App ID or Measurement ID. Sending any event with a transaction ID as an additional data source requires property allowlisting. The post was authored by Lindsey Volta on behalf of the Data Manager API Team.
