There are multiple ways to incorporate our unified payment gateway platform within a website, a payment device and mobile device. We provide different options which work best for you based upon ease of integration, required resources, features, and additional security.

Pre-certified SDKs


If you are integrating payments into your software and need to speed up your time to market by avoiding complex and lengthy processor certifications you can use our SDKs. These give you access to a vast list of payment devices pre-certified with our SDK, connected to the most popular acquiring processors.

Are you developing on Windows?

We have created a downloadable payment device emulator for Windows so you can be up and running in no time.

Our Windows emulator SDK comprises:

  • Example client source code demonstrating simple integration for your own applications
  • Payment gateway integration guide and API documentation for Windows
  • Example server binaries that work with a Windows virtual payment device

Non-certified solutions

ChipDNA Direct APIs

If you are a terminal device manufacturer wanting to pre-equip your products to work with the NMI platform, you can use the ChipDNA Direct API. We will provide you with integration examples as well as our payment gateway integration guide and API documentation. Unlike with our SDKs, any development using our APIs will require NMI to undertake an EMV Level 3 processor certification of your device, with each processor you want your customers to be able to use. This is by commercial agreement with NMI.

Our MPI is a hosted 3-D Secure merchant plug-in that allows e-commerce sites to accept and process Verified by Visa and Mastercard SecureCode authentications. Its typical usage would be to integrate it into an ecommerce application or site alongside our direct integration in order to provide greater liability shift for the merchant. Using the MPI does not rely on a SDK or any other dependencies, but we have provided PHP.
