I’ve recently discovered that Google is taking major strides in helping advertisers streamline their measurement workflows and enhance audience match rates throughout its advertising ecosystem. Exciting times lie ahead for us marketers!
By incorporating new capabilities into the Data Manager API, Google enables us to send offline conversion data seamlessly across multiple Google Marketing Platform destinations. This can significantly boost Customer Match performance through IP-based matching.
What’s happening. The enhanced Data Manager API now accepts offline conversion event uploads to platforms like Campaign Manager 360, Search Ads 360, and Display & Video 360. This represents an expanded role for the API as a central data ingestion layer in Google’s advertising universe.
We can now rely on a single schema to distribute conversion data across several Google products, which is a game-changer compared to our previously disjointed workflows requiring individual integrations. Additionally, this API supports encrypted user identifiers, including email and phone numbers, enabling event routing to multiple destinations with just one request.
Between the lines: Google is urging us who still use the Campaign Manager 360 API for conversions to transition to the Data Manager API. They assure us that the new framework not only simplifies implementation but also offers more flexibility in measurement and attribution capabilities.
What’s new and fascinating is the introduction of IP ingestion support for Google Ads Customer Match through a new CompositeData field. This means alongside traditional identifiers like email and postal addresses, we can now upload IP addresses as well.
Starting in Q3 2026, incorporating IP addresses with corresponding observation timestamps promises us enhanced Customer Match rates, potentially widening audience reach and elevating match precision.
Why we care. These updates simplify the unification of conversion measurement across Google’s ad products and improve audience matching. For those of us managing large-scale data programs, the benefits could include better attribution and more effective audience targeting.
The bottom line. With the Data Manager API being positioned as the ultimate hub for conversion and audience data, Google offers us a more cohesive system to manage measurement and improve Customer Match across its platforms. Check it out for yourself through Google’s official blog post.
