How to track installs and payments on Google Play from different sources?

Question

Android

Hello.
Uploaded the app to Google Play. I want to try to place ads on different sites with pay per install. The application is free. Inside the application there is a donation.
Questions:
1. How can I track the number of app installs for each source site?
2. Is it possible to track the source from which the user who made the payment within the application came from?
3. If you make the application paid (you can install it only by purchasing it) without an internal donation, is it possible to track from which source site the user who bought and installed the application came from.
4. If a user came from a source site to my Google Play app, then closed the play store, and bought the app the next day, can I see which site they originally came from to pay that site to install.
Thanks
