The Google Ads API introduces new features and improvements when upgrading from the AdWords API. This page details some of the highlights of those improvements. For a more detailed list of changes in the Google Ads API, see the release notes.
Key points
Innovation: Extending our innovative ad platform
Expect more frequent releases with additional features and improved upwards compatibility. The many new features such as automated recommendations to help increase campaign performance, are just the start of our efforts to provide an innovative and full-featured advertising API. With more frequent releases, the Google Ads API can roll out new features and bug fixes more often.
Productivity: Faster, easier to build applications
The Google Ads API simplifies building applications with less code, making time to market faster for applications. There’s seamless integration between reports and updates, along with a flexible and intuitive query language for scalable reporting. This update makes the API consistent with Google's latest standards.
The legacy AdWords API will be shutdown in April 2022
September 2018 was the last release of the AdWords API. As announced in April 2021, the AdWords API will sunset April 27, 2022. As a result, new features will only appear in the Google Ads API, and there may be deprecations in the AdWords API, such as feed-based extensions.
