Netbilling, a payment gateway company recently abandoned the free shopping cart provided to their customers. As a result webmasters scrambled to find a new solution to continue accepting credit cards with no downtime. A client reached out to me for a new payment gateway for use with Netbilling.
Netbilling provided detailed documentation on what variables that needed to be passed.
I created a new payment gateway for Netbilling using WP E-Commerce (WordPress Plugin)
