Google Ads Scripts Get Merchant API April 22, 2026
Google announced that the Content API for Shopping will be replaced by a new Merchant API, with the Content API sunsetting on August 18, 2026. The Google Ads scripts editor will begin rolling out support for the Merchant API on April 22, 2026. The Merchant API uses a modular, sub-API design and adds features including the Google Product Studio API (generative AI), Reviews APIs, Notifications API, expanded data-source management (supplemental product data, local and regional inventory, promotion data), and omnichannel support with a legacy_local compatibility flag. The Merchant API will be available as an Advanced API in the Google Ads scripts editor; Google published a migration guide and invited developers to discuss the change in its Advertising and Measurement Community Discord.

Google Ads API expands product reporting June 15, 2026
Google announced that starting June 15, 2026 the Google Ads API will broaden product reporting to include data from all Performance Max networks and provide more comprehensive metrics across campaign types and channels (Performance Max, Shopping, Video, App, Demand Gen). Cost and conversion metrics for shopping_product will begin returning data for Video, Demand Gen and App campaigns (previously limited). All campaigns using Google Merchant Center will return results via shopping_performance_view, and Performance Max will expose all networks in that view — which may cause a one-time increase in reported product metrics. The expanded data will be available only for queries covering June 15, 2026 onward; historical requests for prior dates will not include the new metrics.
