Starting from March 29, 2023, the Google Ads API v11 will no longer be available. Developers still using v11 after this date will notice API requests failing. To migrate to the newest version, visit the Google Ads API documentation here. Once a version is sunset, all API requests using that version will fail, potentially causing disruptions to campaign management and optimization. By staying up-to-date with the latest version of the API, advertisers and developers can access new features and improvements, ensuring your campaigns are running efficiently and effectively.
