Technical Integration

Eazy breezy

Integrating our web payment services is pretty straightforward. We provide an XML feed of all the available countries and price points with corresponding URLs to call for each. Once your customer selects the price point to pay, you send him to us and we walk him through a fast, carrier-compliant payment flow. Once the payment is complete, we hit your Callback URL with all the transaction information for your records. We serve up the payment flow GUI in a small iFrame window that you can either embed in your webpage or serve in a separate browser popup window.
