Use case
The product currently has a requirement, which requires statistics on which link or advertising channel users used to jump to the app market (Apple Store/Google Play) before downloading the app.

Proposal
I also checked some information online and found that there are many third parties, but they require fees. I would like to know how I can achieve this requirement without using a third party? Or does the official already have a mature solution/plug-in, but I just didn’t find it.
Please help me resolve my doubts, thank you very much.
