Stat tracking without using the google console

Hi everyone,
First off I would like to thank everyone who helped and answered my questions. I was finally able to publish my first app (which is pretty basic but still).

Now to my question. I noticed that the google play dev console didn’t update the numbers of downloads fast (even in a hole night it didn’t update). I then read about API’s that you could implement in your app in ordder to track the downloads live. Does anybody know how to do that and which API to take ?
