Intergrated Visa/Master card online card processing facility through Hatton National Bank (HNB) Sri Lanka. The service is provided by Cybersource IPG through the bank.
Of the few methods of intergration, we used the Hosted Checkout procedure along with our custom built PHP based back end. Also built the backend to log success/failed transactions, status, errors, etc along with an automated receipt emailing service.
