Field reference

|---|---|
| Credit Card Processing Enabled | Enable to accept credit card payments. |
| ACH Processing Enabled | Enable to accept ACH (bank account) payments. |
| Username | Your NMI gateway username from your payment processor. |
| Password | Your NMI gateway password. Leave blank to keep the currently saved password. |

- Payments fail with "duplicate transaction" — If legitimate transactions are being rejected, enable Disable Duplicate Transaction Check temporarily while you investigate.
- Gateway not appearing — Contact SecurityTrax support to confirm the gateway is enabled for your company.
