Downloading files after order payment?

Question

CMS

Guys, I need your help, I'm creating a site on Tild and I can't figure out how to do it so that after clicking the "buy" button and paying for the order (courses in pdf), the order is downloaded from the buyer or sent to him by mail. Insert a link into the button with the "cloud" is not an option, the order is downloaded, before payment. I ask for your help. Thank you.

Answer 1

Here, many depend on the payment system. For example, in Yandex, you can specify a link to which the user must be turned away after a successful payment, how it works on Tilda, I have no idea.
