How to determine the source of iOS application installation?

Question

iOS

There is an application, I would like to firstly determine where a person downloaded it from, from which landing page. Secondly, letters with an installation invitation come from existing users, I would like to make sure that after installation, an account is automatically created for a person. I saw that some apps throw off links of the form: https://itunes.apple.com/us/app/app_name/params
By params, they determine, as I understand where they came from, how is this done?

Answer 1

It is possible through third-party services, AppsFlyer for example.
