I am trying to implement GPAY to my desktop application, where users can pay through website and also get paid.
I am trying o use GPAY direct tokenization method with out using 3rd party gateway. I got the encryption part. 1) In case of direct tokenization,Do my application need to act as a payment processor and have code which handles charging different cards. IF so,how complicated is this and I am looking for any reference material.
2) how complex is to get PCI DSS compliance
3) Overall how much time it takes to implement GPAy with out 3rd part payment gateway?
