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.

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.

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.

The Content API for Shopping will sunset on August 18, 2026, to be replaced by the Merchant API. This migration provides a shift toward more robust, scalable, and feature-rich integrations. For Google Ads scripts users, the Google Ads scripts editor will begin rolling out Merchant API support on April 22, 2026. While the Content API for Shopping will remain available until its sunset, here’s what to expect from the Merchant API.

Understanding the Merchant API

The Merchant API offers important changes and improvements over the Content API for Shopping:

• Modular Design: The Merchant API is broken down into sub-APIs. This allows for:
  • Faster access to new features and updates.
  • Easier versioning and maintenance.
  • Reduced disruption, as changes in one sub-API are less likely to impact others.
• New Features & Capabilities:
  • Google Product Studio API: Leverage generative AI features.
  • Reviews APIs: Upload and manage product and store reviews.
  • Notifications API: Enable notifications for changes.
  • Expanded Data Source Management: Create and manage various data source types, including:
    • Supplemental product data
    • Local inventory data
    • Regional inventory data
    • Promotion data
• Omnichannel Support: Designed with Omnichannel in mind, though it provides backward compatibility for legacy separate online/local offer structures using the legacy_local flag.

Take a look at the Merchant API migration guide for more detail on the changes between APIs.

How to get started

The Merchant API will be available as an Advanced API in the Google Ads scripts editor, just as the Content API is.

In today's fast-paced digital landscape, managing multiple data pipelines can feel overwhelming. If you're a developer navigating the complexities of audience management and conversion tracking, you might be wondering: how can I streamline my processes and reduce costs?

This week’s episode of Ads DevCast explores the new Data Manager API, which will transform the way you connect data across various Google ad platforms, making your workflows more efficient and cost-effective. This product solves many of the complexities developers and agencies have had to juggle across multiple APIs—each with its own schema, maintenance requirements, and learning curve.

About our Guest

In this episode we sit down with Melissa Ng, Product Manager for Data Manager API, to discuss how Google is streamlining these processes and what it means for your development workflow.

Melissa is a seasoned Product Manager, specializing in ads measurement at Google for the past four years. Her deep understanding of customer needs and data management challenges drives her passion for creating innovative solutions like the Data Manager API.

What are we solving for?

Every advertising product has its own unique requirements that aren't necessarily interoperable. This fragmentation creates confusion, slows down onboarding, and drives up engineering costs. It also makes it difficult to build the kind of cohesive "Data Strength" needed to fuel modern advertising and maximize conversions.

In a joint case study, one of our advertisers reported spending over $1 million annually on maintenance alone. We needed to provide a unified ingestion point for conversions and audiences, effectively reducing confusion and simplifying data management.

Enter the Data Manager API

The Data Manager API is Google's answer to this complexity. It allows data partners, agencies, and advertisers to send first-party data to multiple Google advertising products—such as Google Ads, Display & Video 360, Campaign Manager 360, Google Analytics, and others—in a single call.

"This means that when you’re sending in a field for, say, 'transaction id', that field means the same thing in all of the downstream use cases across all of the Google advertising products," explains Melissa in the episode.

While the primary motivation behind developing the Data Manager API was to address complexities associated with maintaining multiple APIs, there are other benefits as well:

• Ease of Use and Efficiency at Scale: You can achieve significant savings in resources. Treasure Data, one of our early API integration partners, reported a 2x faster advertiser onboarding process and an 80% reduction in engineering efforts.

• Privacy by Default: End-user privacy is non-negotiable. The Data Manager API features confidential matching right out of the box for audience solutions like Customer Match. This utilizes a Trusted Execution Environment (TEE) to ensure that no one—not even Google—can view the processed data. (Read more)

• Future-Proofing Your Stack: The Data Manager API is the future of audience and conversion management. Any new features for audience or conversion management will be implemented in the Data Manager API going forward. (See our timelines)

• Enhanced Diagnostics: For the first time, API stats and diagnostics will soon be available directly in the Ads UI, providing visibility into the health of your connections and downstream asynchronous errors, saving you countless hours of troubleshooting.

Tune In and Take Action

If you are managing audiences or conversions programmatically, this episode is a must-listen. It is packed with insights, roadmap updates, and advice on how to seamlessly migrate your existing systems.
