What literature to read about the work of electronic payment services?

Question

Payment systems

We are planning to integrate an online store with an electronic payment service (similar to PayPal and YaD). I would like to understand in more detail the scenarios of work, the schemes of interaction not only between the IM and the service, but also between the service and the bank and other clients, in order to take into account all the pitfalls that are not described in the API documentation.

Answer 1

Everything is set out in an agreement with a specific bank and with a specific payment system.
Problems of interaction of the payment system with VISA / Mastercard and the issuer will not concern you.

Answer 2
