Starting in the upcoming Google Ads API v10 release, you’ll have to use unique asset names within your Google Ads account. This affects asset names for image and media bundle asset types. The reason we’re making this change is to make it easier to identify assets with human readable names as your collection of assets grows.
Starting on February 9, 2022 a default asset name will be assigned during creates and updates for all existing Google Ads API and AdWords API versions. If you wish to set the asset name yourself, then update your code to set the asset name before this date.
If you have questions while you’re updating your code, please reach out to us on the forum or at googleadsapi-support@google.com.
