Limitations
-
The NMI gateway does not have different endpoints for test and production. In order to use a test account, a customer will have to go to their merchant control panel (Settings > Test Mode > ‘Enable Test Mode’).
-
The Use Test Gateway setting does not impact this gateway because enabling the testing environment is driven by the credentials and settings in the Merchant Portal
-
By default, all gateway accounts have a duplicate threshold setting of 1200 seconds (20 minutes). This time period can be adjusted, overridden, or turned off completely. Customers will have to contact their merchant service provider to adjust this setting.
