NMI

NMI is a processor-agnostic payment gateway used by ISOs, software platforms, and merchants to route card and ACH transactions to the bank or acquirer that settles the funds. Rather than being tied to a single acquirer, it maintains connections to a wide range of processors, which lets a merchant keep the same integration while switching or splitting the acquiring relationship underneath. It has a strong presence in the United States and United Kingdom and is commonly used for online, MOTO, and recurring payments. The connection to NMI uses the API credentials (username and password) of a dedicated user on your NMI account.
