The NMI (Networks Merchants) Payment Gateway can be integrated into the Pinnacle Cart Software using the Authorize.net emulation that NMI offers. To utilize this, you will want to configure the cart to use the Authorize.net Gateway, but then plugin your credentials for your NMI account.
You will first need to sign up with NMI (www.nmi.com) to create and activate the payment gateway account.
Once your account has been successfully setup, Go to Cart Settings -> Payment Methods and select the radio button for "Accept credit cards and / or other processing methods". Then select Authorize.net Aim 3.1 from the list and click configure gateway.
This will bring you to the configuration page, where you will want to provide the URL to the Gateway that NMI has provided, in addition to your Login/User name and Password/Transaction Key.
After all the settings are typed in, click save changes and proceed to test the payment gateway.
