Google is introducing a new Data Manager API that makes it easier to connect your first-party data to Google’s AI-driven advertising products. The aim is to deliver stronger measurement, more accurate targeting, and better performance while reducing the complexity of juggling multiple systems.
Why we care. The Data Manager API lets you squeeze more value from your existing first-party data by feeding clean, consistent signals into Google’s AI. That leads to better targeting, more precise measurement, and smarter bidding. It also consolidates several older APIs into a single integration, lowering engineering overhead and speeding up how quickly insights flow back into your campaigns.
About the Data Manager API. This new API will unify and replace multiple Google platform APIs, giving advertisers, agencies, and developers one central connection point. It extends Google’s codeless Data Manager solution, which already helps tens of thousands of advertisers activate their first-party data.
You can use it to:
- Upload and keep audience lists up to date.
- Send offline conversions to enhance measurement accuracy.
- Boost bidding performance by supplying Google AI with richer, higher-quality signals.
Partnership push. To accelerate usage, Google is launching with integrations from AdSwerve, Customerlabs, Data Hash, Fifty Five, Hightouch, Jellyfish, Lytics, Tealium, Treasure Data, Zapier, and more partners.
Available today. The API is now live for Google Ads, Google Analytics, and Display & Video 360, with additional product integrations planned.
