Better integration development

No matter what sector you’re in, we provide multiple SDKs and APIs for in-store, mobile, online or self-service payments. Our SDKs and APIs are used in retail, hospitality, medical, dental, gyms, charities and more but we also work with system integrators in parking, transportation or vending and understand it’s no easy task to combine existing ticketing or kiosk hardware with card readers. Our SDKs and drivers for pre-certified payment devices from major manufacturers, simplify your work and allow you to deploy full card payment on your terminals in the shortest time.

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
  • 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 prefer to do your own EMV Level 3 processor certification, you can interface directly with our unified payment enablement platform using our API. We will provide you with integration examples for your own applications as well as our integration guide and API documentation. Unlike with our SDKs, any development using our APIs will require additional processor certifications for your chosen payment device.

Online

Our ecommerce solution

We provide some of the most secure yet easy to integrate online payment solutions. You play a key role in getting businesses equipped for online payments, so we have designed our solutions with your ease of integration in mind.

Three-Step Redirect API

The Three Step Redirect API is the preferred API for customized web-based payment processing. Using this integration method significantly reduces a merchant's PCI footprint without sacrificing end-user look and feel. This method is required when using Verified by Visa/Mastercard SecureCode (Payer Authentication).

Direct Post API

The Direct Post method is the simplest integration method for both web-based and non web-based payment applications, however, merchants using this integration method should have passed a PCI vulnerability scan before use.

QuickClick Hosted Payment Page

QuickClick is a great option for e-commerce merchants who do not have an IT team or developer on staff. A button-generator is included, which allows merchants to create website links to products and services without any previous development experience.

Third Party Shopping Cart Integrations

There are a number of third party shopping carts that have integrated to the payment gateway. This is the best option for merchants who need a full featured turn-key shopping cart out of the box.
