Hi,

Please tell me the way add new payment gateway (OnePAY-Credit card).

OnePAY payment gateway use HTTP Redirect method to pay the transaction.

That mean, it has module source with 3 files,

1. File Form payment is all fields which needs set value. Including Merchant Account, Transaction Info, Amount, version,...
2. Second file is called DO file which process field,values of Form payment and issue Hash Code to authentication transaction before redirect to OnePAY gateway.
3. After payment in OnePAY Site, OnePAY redirect to my website and the result will be submit to Receipt file (that called DR file).
DR file will validate all values of payment gateway and then so state of transaction (successful or failed)

Please tell me the way to add on OnePAY payment gateway.
thanks
Vuong
