We have a self-written CRM, which is connected to Sberbank online acquiring through REST: when an order is created, we send the client to the address sent by Sberbank, after which the client does not pay for the purchase.
But there is a need to open a real physical office, where we could let customers pay for their orders by card through a cash register. Question: Is it possible to send a signal from the CRM via the same REST or another way to the cash register so that it prepares a transaction for payment with all the necessary parameters (order number, service name, etc.). In this way I would like to avoid all the hassle of entering nomenclatures into the cash register itself, especially since their list changes regularly.
I have studied the question, but perhaps poorly, and have not found adequate answers to it. Thanks to those who will give at least some useful information!
