From September 7th 2020, the expandedImage field for the Showcase Ad type will be deprecated. This change is part of updates to the Showcase Ad format communicated directly to users in July 2020. After this update, header image assets will no longer appear to users, and you will no longer be able to add or edit these assets using the AdWords API. This deprecation only affects users of AdWords API.
As a result of this deprecation, the following behaviors will change only in the AdWords API:
Setting a value for expandedImage on a Showcase Ad is no longer required and will be ignored for ADD or SET operations made using AdGroupAdService or AdService, respectively. This is the same behavior as for collapsedImage.
For Showcase Ads created before the deprecation, requesting the expandedImage field will return the previously set image. This image will no longer be used by the Showcase Ad.
For Showcase Ads created after the deprecation, requesting the expandedImage field will return null.
Any errors related to setting expandedImage, for example RequiredError.REQUIRED will no longer be thrown.
Provided your code does not expect an Image to be returned when requesting ShowcaseAd.expandedImage, then no code changes are required for this deprecation.
