What design pattern can be applied to integrate external payment systems?

Question

Software design

There was a task on acceptance of payments from users.
There is a list of several providers like Yandex.Checkout, a direct bank API, it seems there will be something like WebMoney, and even a cryptocurrency exchanger.
Is it worth creating some pattern in the program in order to tie it all together somehow in a unified way? Or directly implement a class with the necessary methods for each system and not take a steam bath?

Answer 1

It depends on the situation, but I suspect that Facade and / or Adapter can help you.
