Many payment systems and one cash register, how should it work?

Question

PayPal

Hello, I have a question about the operation of cash register equipment and several payment systems. Who in this case should issue a check? Should the payment gateway issue a check or should the site contact the cash register via api and generate a check and send it to EMAIL in the future?

Answer 1

the check is issued by the company that sells goods / services - this is its responsibility, not payment gateways. you generate a check through the api of the cash register, the cash desk sends the check to the OFD
, and the OFD already sends the check to the buyer by email or to the phone via sms. json form here https://kkt.astral.ru/catalog/kupit/onlayn_kassa_m...
