The NMI gateway login is nmi.com/logins. That single sign-in opens Merchant Central — the dashboard where you key transactions in the Virtual Terminal, pull reports, and manage settings. Because NMI is a white-label platform, merchants onboarded through a reseller may sign in at a branded gateway URL instead; it runs on the same NMI infrastructure and opens the same dashboard.
"NMI gateway login" and "NMI merchant login" are, in practice, the same door — the gateway is what you log into, Merchant Central is what you see once you are in. This page focuses on the gateway access itself: the URL, the relationship to the dashboard, and the handful of issues that block sign-in.
The gateway URL
For a direct NMI account the gateway login is nmi.com/logins. NMI sells overwhelmingly through partners, though, so most merchants reach the gateway through a branded host their reseller configured — for example gateway.theirbrand.com. That branded URL points at NMI's platform; the login form, the dashboard, and the features are identical. If you do not know your URL, it is in the welcome email from whoever set up your account.
Gateway login vs. Merchant Central — same thing
"Gateway login"
The act of signing in at nmi.com/logins (or your branded URL) — the authentication step.
"Merchant Central"
The dashboard you land on after that sign-in — Virtual Terminal, reports, settings, the Customer Vault.
People search both phrases looking for the same place. For detail on the dashboard itself, see Merchant Central.
People also ask about the NMI gateway login
Is the gateway login the same as the Merchant Central login?
Yes. The gateway is the platform; Merchant Central is its merchant-facing dashboard. When you log in to the gateway, you land in Merchant Central. There is not a separate sign-in for each — one set of credentials opens both.
Can I log in to the NMI gateway from my phone?
Yes. Merchant Central is browser-based and responsive, so you can sign in from a mobile browser to look up transactions or key a charge in the Virtual Terminal. For dedicated mobile card acceptance, NMI offers SDK-based apps through resellers — see mobile payments.
Why does the gateway login reject my correct password?
Most often you are on the wrong host: a branded-account merchant on nmi.com/logins, or a direct-account merchant on a branded URL. The screen loads fine but the account does not exist there, so the password fails. Confirm your correct gateway URL first, then check for an account lockout from earlier attempts.
Troubleshooting
- Wrong host: confirm nmi.com/logins vs. your branded reseller URL.
- Locked account: wait out the cool-off after failed attempts, then reset the password.
- Browser issues: clear cache, disable conflicting extensions, or try another browser if the page won't load.
- Reseller-suspended user: credentials that suddenly stop working may mean the provider disabled the user — contact them.
FAQ
What is the NMI gateway login URL?
nmi.com/logins for direct accounts, or a reseller-branded URL from your welcome email for white-label accounts. Both open the same Merchant Central dashboard.
Is it the same as logging into Merchant Central?
Yes — the gateway is what you sign in to, Merchant Central is the dashboard you reach.
Why won't my password work?
Usually because you're on the wrong host for your account, or the user is locked from prior attempts. Confirm the URL and wait out any lockout.
Does this site host the gateway login?
No. We're an independent reference and never collect credentials. The button here opens the official nmi.com/logins.
