April 2026 update to Display & Video 360 API

Today we’re announcing the April 2026 update to the Display & Video 360 API. This update includes the following:

• Support for additional Exchange and ThirdPartyVendor values.
• AdAsset identifier fields in objects used in AdGroupAd resources.
• Beta support for Demand Gen resource management.
</ul>

While Demand Gen campaign support is in beta, it is only available to allowlisted customers. See our guide for detailed instructions on how to create a Demand Gen ad campaign. If your partner is allowlisted:

• Demand Gen line items, ad groups, and the relevant targeting will be included in relevant get and list requests.
• Demand Gen line items, ad groups, ads, and the relevant targeting can be created, deleted, and updated.
</ul>

We aim to launch full Demand Gen support for the Display & Video 360 API in general availability later this year. This will be announced with a future release.

For a complete list of new features in this update, see the Display & Video 360 API release notes. Before using these new features, make sure to update your client library to the latest version.
