How to make an imitation of a payment system?

Question

PHP

I’m sawing my bike on the vp, I want to test it and write a response handler. For example, on click, it takes me to a page with a "payment", where I entered and or did not enter data in the field and the server returned the answer, and I was thrown back to checkout.

Answer 1

Almost all payment systems have a test mode just for this.

Answer 2

Hello!
I agree with colleagues. Definitely there is some kind of test account to check. Sometimes they provide not only the key to the API, but also fake credit cards to simulate payment.
It may be that they are not written in the documentation. Contact Support
