On April 5, 2021, support for Showcase Shopping ads will be removed from the AdWords API. Users will no longer be able to create or update the following Showcase Shopping objects, and attempts to do so will result in the following errors.

Object Error
AdGroups

with adGroupType SHOPPING_SHOWCASE_ADS		 OPERATION_NOT_PERMITTED_FOR_CAMPAIGN_TYPE
AdGroupAds containing ShowcaseAds OPERATION_NOT_PERMITTED_FOR_AD_GROUP_TYPE


Any remaining Showcase ad groups will be set to REMOVED status, and remaining AdGroupAds containing ShowcaseAds will be set to DISABLED status and stop serving. Developers can still retrieve historical metrics for these ads and ad groups by fetching reports that explicitly filter to include REMOVED or DISABLED objects.

This change only affects AdWords API users. Management of Showcase Shopping ads is not supported by Google Ads API or Google Ads scripts.

If you have any questions or need additional help, contact us via the forum or at googleadsapi-support@google.com.
