Which payment automation service to connect to the site?

Question

Billing systems

Hello dear people!
I created a website for selling an information product (video tutorials). Now I need to connect a payment service that will combine Yandex.Money, WebMoney and all other payment systems so that buyers can buy an information product (it is one). There are a lot of these services! And I don’t know how to choose from them, given that I am an individual. And as a bonus, it is necessary to make sure that the client, having paid the cost of the information product, would receive it automatically by mail. Maybe someone knows a direct way to solve my question?

Free-Kassa look, I use it

Answer 2

Yandex Checkout
