I need for my open cart based website a payment gateway:
[login to view URL]
Extensione must be compiant with open cart 2.x versions.
To greatly simplify your work I'll supply you with the attached working php example.
It uses the following parameters:
$shopLogin = 'gespayXXXXX'; //YOUR SHOP LOGIN Eg. production code '9000001' , test code 'gespay0001'
$currency = '242'; //payment currency 242 -> Euro
$amount = '0.05'; //payment amount
$shopTransactionID = 'YourOrderIdentifier'; //your payment order identifier
$amount and $shopTransactionID should be got from open cart checkout session
Scurrency will always be 242
$shopLogin: just use test code gespay0001 and then let me know in production how to manage such value
Once you got the encrypted variable a and b, a redirect to payment server is required (instead of the form you see in the example).
Finally open cart must manage server response (OK or KO)
