NMI Integration — Manage NMI Transactions in One CRM
Midcove connects to your existing NMI account so you can run sales, voids, and refunds, track chargebacks, and layer fraud prevention on top of your NMI MID — all from one transaction management dashboard.
Your NMI MID, run through a better dashboard
Midcove is a payment gateway CRM that connects to the NMI account you already have. You keep your NMI rates and processor relationship — Midcove gives you a faster, clearer way to manage every transaction that runs through it.
- Route sales, voids, and refunds through your NMI MID from Midcove's virtual terminal.
- A unified transaction management dashboard for every NMI transaction, in real time.
- Chargeback alerts tied directly to disputes filed against your NMI MID.
- Payment fraud prevention filters layered on top of NMI's own gateway tools.
What you'll need
- An active NMI merchant account and MID.
- Your NMI API credentials (Security Key or username and password).
- A few minutes to complete the guided connection flow.

NMI integration questions
Do I need a new NMI account?
No. Midcove connects to the NMI account and MID you already have. There's no new merchant account to open and no re-underwriting.
Does Midcove replace NMI?
No. NMI remains your payment gateway and processor. Midcove connects to your existing NMI account and gives you a CRM layer on top — a transaction management dashboard, chargeback tracking, and fraud filters.
What NMI credentials do I need?
You'll need your NMI Security Key, or a username and password with API access, to connect your MID during setup.
Can I use NMI's existing fraud tools alongside Midcove's?
Yes. Midcove's fraud prevention filters run alongside whatever fraud tools you already have configured in NMI, giving you an extra layer of protection rather than replacing what's already in place.
