Google opened access to the Ads API for all users

The Google Ads team announced that it has made the API available to all advertisers and developers.  

The Ads API will allow you to quickly implement new features and update compatibility settings for tools such as recommendations, local campaigns, and more. In addition, developers have improved existing features such as Keyword Planner, change history, and billing. The updates should make it easier to manage campaigns and improve overall performance. 

As a reminder, the AdWords API is also available for use but has stopped being updated. Google recommends all new advertisers to use the Ads API.
