Marketing API: Upcoming Change to Dynamic Media Default Opt-in

作成 Allison Vettasseri

Starting September 1st, 2025, we will begin defaulting the Dynamic Media field (media_type_automation) to OPT_IN for Advantage+ Catalog ads (Single Image, Carousel, and Collection formats). This change brings parity with Ads Manager which has the Dynamic Media toggle “On” by default, increasing creative liquidity and improving utilization of Catalog Product Video (CPV) assets to drive better ad performance.

This change will affect all Advantage+ Catalog ads created using the Marketing API after the launch date and be applied to Single Image, Carousel, and Collection ad formats.

What is the expected behavior before and after the change? Before: Dynamic Media is disabled by default for Advantage+ Catalog ads via the API. After: Dynamic Media will be enabled by default for these ads unless explicitly opt out.
When will developers need to implement the code changes? Developers should review and update their API integrations before September 1st, 2025, if they want to opt out of Dynamic Media.
When will they have until to implement the code changes? The rollout is gradual, starting on 1st September 2025 and with 100% enforcement by October 20th, 2025.
Is there any recommended guidance to prepare for this change? Partners and advertisers should ensure that videos are only added to product catalogs when they are ready for immediate ad use. Partners may also continue to utilize preferred_video_tags and add tags to the videos within their product catalogs. For more information on preferred_video_tags, please reference the Dynamic Media FAQ page.
