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. Shuttle connects to NMI using the API credentials
(username and password) of a dedicated user on your NMI account.
