Greetings !
There are following two ways to do so:
SIMPLE/CHEAP and QUICK solution : We have a third party payment gateway at back end, but in this case the deductions will show the paypal to user.
CUSTOM/Effective and Lengthy solution: We build a Custom Payment gateway.
What you need to do ?
--> Decide a bank for the integration and we have it's API and built our own payment gateway with it with same.
We recently did related concept for a Client's Market Place in UAE, with HSBC bank.
