Technical Information
All communication between the web shop and Borgun‘s Secure Payment Page is by POST via HTTPS.
Production URL: https://securepay.borgun.is/securepay/default.aspx
Sandbox URL: https://test.borgun.is/securepay/default.aspx
The process steps between web shop and Borgun are as follows:
Process initiation, web shop redirects buyer to Borgun‘s payment page with cart and payment information
Buyer can take two actions:
Push Cancel button and be returned to the cancel url supplied by web shop
Supply credit card information and finalize payment
As soon as payment is concluded the Borgun server sends a payment confirmation to the web shop with the success url supplied by web shop
Receipt of transaction the displayed to the buyer
After pressing the Back to shop button the buyer is redirected to the success url supplied by web shop
A secret key, known only to the merchant and the payment page is used to verify that the HTTPS communication is between the correct partners. The key is never sent directly over HTTPS, it is added to a HMAC signature function and thus sent indirectly. Detailed description of how the signature is created is in the Parameters chapter. You can check the HMAC signature on several websites, for example http://www.freeformatter.com/hmac-generator.html
