Google updated the Data Manager API with new audience management tools, more flexible data ingestion and expanded support for user-provided address data, making it easier for developers to maintain Customer Match lists and improve data quality.
The release is aimed at reducing manual work while providing better visibility into data issues that don’t require an ingestion request to fail.
What’s new. The headline addition is a new RemoveAllAudienceMembers method, which allows developers to clear an entire audience list in a single operation. An optional timestamp parameter also lets advertisers remove only members added before a specified date, making full audience refreshes much easier.
Google has also introduced field-level ingestion warnings. Rather than failing an entire request when optional fields contain invalid data, the API now processes valid records while returning detailed warnings that identify the problematic fields and explain why they failed validation.
The update also expands the address information that can be sent to Google Analytics destinations. Developers can now include street address, city and state or province alongside existing fields such as name, postal code and region, while user-provided data can also satisfy identifier requirements for certain multi-source events when other identifiers aren’t available.
Google has additionally released new AI agent skills in its Google Skills GitHub repository to help developers build Data Manager API integrations more efficiently within AI-assisted coding environments.
Why we care. The update removes several friction points for developers managing first-party data. Audience refreshes become simpler, ingestion issues are easier to troubleshoot without interrupting workflows, and the expanded address fields provide more flexibility when sending user data to Google Analytics.
Bottom line. The latest Data Manager API release streamlines audience management, improves error handling and expands data collection capabilities, giving developers more efficient tools for managing customer data across Google Ads, Display & Video 360 and Google Analytics.
