Display & Video 360 API v5 Adds Responsive YouTube Ad Management

November 13, 2026 Rachel Kim – Technology Editor Technology

Google has updated the Display & Video 360 API to version 5, providing developers with programmatic control over the creation, deletion, and updating of responsive YouTube ads.

The update, announced November 12, 2026, allows users to utilize the advertisers.adGroupAds service to manage AdGroupAd resources by defining ad creative details through the videoPerformanceAd field.

These responsive ads are capable of serving across multiple formats, including in-stream—such as bumper, skippable, and non-skippable—as well as Shorts and in-feed, depending on the specific line item subtype and ad format controls. The management of creative assets for these ads is handled through the advertisers.adAssets service, a process similar to that used for Demand Gen ads.

According to Trevor Mulchay of the Display & Video 360 API Team, the update enables responsive YouTube AdGroupAd resource management for specific line items, including YouTube & partners efficient reach, non-skippable reach, target frequency, and video views. However, the update does not include single format YouTube ads or responsive YouTube ads under YouTube Programmatic Non-Guaranteed and Guaranteed instant deal line items.

Users must continue to manage the creation and updating of YouTube line items, ad groups, and targeting parameters via the Display & Video 360 interface or through Structured Data Files (SDF) upload. The recommended workflow involves uploading Line Item and Ad Group SDFs, retrieving or creating necessary assets using the advertisers.adAssets service, and finalizing the ad creation with advertisers.adGroupAds.create.

The Display & Video 360 API v5 is currently in public beta. Google said that breaking changes may still occur, with updates to be announced via the company blog and release notes.
