Starting July 14, 2025, Google Ads scripts will generate errors for requests related to ad customizers for expanded text ads and feed-based legacy ad extensions.
Ad Customizer Changes
Requests involving Ad Customizer entities, such as AdsApp.AdCustomizerSource or AdsApp.newAdCustomizerSourceBuilder, will return sunset errors. These entities have been read-only since their deprecation in 2022 and have not been served on any ads since May 2024. They were completely removed from the Google Ads API in the v19 release.
Ad Extension Changes
Feed-based Ad Extensions were sunset in 2022 in favor of asset-based extensions. Users were encouraged to migrate or were automatically migrated, retaining access to legacy functionality via withOnlyLegacy() methods. The withOnlyUpgraded() method was introduced to utilize only upgraded asset-based extensions. From July 14, 2025, legacy functionality will be eliminated, causing withOnlyLegacy() methods to throw sunset errors. The withOnlyUpgraded() methods will issue a warning, as specifying asset-based extensions will no longer be necessary.
