Last month, Google announced the start of the testing with Google Ads API. Google Ads API is the next generation of the current AdWords API and according to Google, as the API gradually rolls out, it will reach full parity with the current API.
Google Ads API is now on Beta and advertisers can apply for access here. Google Ads API is for ad agencies, search engine marketing (SEM) companies, and big brands managing a large number of accounts, with needs beyond what’s possible within the AdWords UI.
On Google Ads API, advertisers can do account management, custom reporting, ad management based on inventory, and bid management based on business data.
