How to generate an electronic check?

Question

PHP

Greetings readers.
I connected a payment from Alfa Bank to the online store, the store engine is self-written. Payments go through, everything works correctly.
But now you need to send an electronic purchase receipt to the buyer by email.
How to implement this, is it necessary to connect some third-party service for this?
In the alpha documentation ( https://pay.alfabank.ru/ecommerce/instructions/FZ_... ) there is a request for information about a cashier's check on page 242, but I don't understand what to do with this information? Just make up an html letter by inserting it there and send it?
I hope someone has come across a similar problem or just knows how to solve it.

You need to connect a fiscal data operator. As a rule, there are 2 options:
1. You indicate the data for the fiscal data operator in the bank's personal account and transfer the list of goods + additional data for the check (VAT, type of taxation, etc.) when paying.
2. When placing an order, after paying for it, a list of goods + additional data for the check is sent directly to the fiscal data operator. You also need to register sending for a refund, for a partial refund, and so on.
