I worked on Paypal Gateway integration on the client's website where
Payment request get generated - User get transfer to his/her Paypal account - there he completes his transaction via either through card or PayPal balance or bank attached to his/her account. - we do get a proper response as well.
Currently, the system working finely. Now we want to add a facility to pay via net banking to a merchant's PayPal account. I tried to search on the net to get lead for this but did not found any. do anyone had implemented this, right now I dont have any code to post it here.
