How to create a referral system on the site?

Question

PHP

Interested in options for creating a system of referral links for the site, such that by following the partner's link to this site, the client is attached to him (the partner) using unique data (cookies, etc.) and subsequently, if the client makes an order on the site, the owner of the link is charged a certain percent.
Perhaps there are ready-made solutions to this problem or do you need to implement it on an individual basis?
Thank you)

Answer 1

If you have any CMS, then there may be a ready-made plugin for it.
But most likely for such purposes on an individual basis.

Answer 2

the referrer is passed either to the url or to the session. further, on the site side, you need a handler (plugin) that will connect the referrer with his actions on the site.

Answer 3

They are right about plugins, but if you need beautiful analytics and the ability to work with a referral database, then look towards Ambassador .
