Categories: NMI Support
NMI connects with dozens of major shopping carts, and has detailed integration documentation for most shopping carts.
The NMI gateway allows you to enter “Test Mode” so that you can make edits to the gateway and test your website connection, without passing through live values. This is perfect if you’re working with a developer or a custom integration and you need to ensure that the connections to NMI are sound.
Once logged into the NMI gateway, voiding a sale through the Virtual Terminal is easy. Remember it’s always better to void a sale than refund it, assuming the original transaction took place same-day.
