Entering Test Mode for NMI

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.
