Google announced the Data Manager API, a unified way for advertisers, agencies, and developers to connect first-party data to its advertising tools through one secure connection rather than several separate APIs. The API lets teams build automated connections that upload audience lists and submit offline conversion data to improve measurement and bidding, and it complements the existing codeless Data Manager already used by tens of thousands of advertisers.
To help more marketers connect with the Data Manager API, Google named a set of partners including Datahash, alongside Adswerve, CustomerLabs, fifty-five, Hightouch, Jellyfish, Lytics, Tealium, Treasure Data, and Zapier. At launch the API is live for Google Ads, Google Analytics, and Display & Video 360, with more integrations to follow. Google’s announcement quotes a launch partner reporting an 80% reduction in engineering effort to connect customer data to Google Ads in near real time.
The partnership reflects the direction Datahash Signals is built for: routing first-party conversions and audience signals to each platform through its native, partner-verified interface.
