  Open the Dashboard page  (found under APIs & Services ) in the Google Cloud Console. 
  Click on Google Ads API  in the table. 
  On the METRICS  subtab, you should see your recent requests plotted on each graph. At the bottom of the page, you’ll see the Methods  table, where you can see which methods you’ve sent requests to. The method name includes a Google Ads API version, a service, and a method name, e.g., google.ads.googleads.v11.services.GoogleAdsService.Mutate. In this way, you can see all versions that you’ve used recently. 
  (Optional) Click on the time frame at the top right of the page if you need to change it.
