Connecting a Shopping Cart to NMI
NMI connects with dozens of major shopping carts, and has detailed integration documentation for most shopping carts. You can view the list of compatible shopping carts, here. In addition to integrating with most major shopping carts, NMI also directly integrates with WordPress, Drupal, and Joomla so that you can integrate payment processing directly into your website and buypass a shopping cart altogether.
