Is there a system for processing orders and verifying payment on the landing page?

Question

Payment systems

There is a one-page, it has about 20 products with a buy button, a basket and an input form for full name, address, etc.,
then the person transfers to the Yandex checkout and there he pays for the goods ..
the basket is implemented in javascript.
I need a system in which I can collect all these orders, all the information that the client entered, full name, address, phone number, etc. ... and the very fact of a successful payment.
So that in the system I could see all received paid orders, form an order and send it to the buyer.
The requirements are very simple, are you interested in whether there is a similar service?
I ask you not to offer CMS engines, this option is already being worked out ...
