Sawing on trip your bike, I want to test and write a response processor. What, on click I open the page with the "payment" where I have entered or not entered data in the field and the server returned the answer, and I threw back on checkout.
Almost in all payment systems there is a test mode just for this

I agree with the colleagues. Definitely have a test account to check. Sometimes they provide not only the key to an IPA, but left credit cards to simulate the payment.
It may be that their documentation is not written. Contact support
