EBT

Overview

This page contains all API documentation for Electronic Benefit Transfer (EBT) transactions. For more information regarding account access, navigate to the Transaction API parent page.

How to Generate Cardknox Keys

1. Sign in to the Cardknox Merchant Portal.

2. Select "Account Settings" from the navigation bar.

3. Select "Keys" from the sub-menu.

4. Click "Create a Key" in the top-right corner.

5. Choose the desired key type (API or iFields), description (software, etc.), and permissions.

6. Click "Create and View" and copy your key.

It is critical to copy your key and save it in a secure location, as you won’t be able to obtain the key again.

iFields and Transaction API

We recommend using iFields in conjunction with the Transaction API for added security. Cardknox iFields is an iFrames solution that keeps sensitive card data away from merchant servers while granting you complete control over form layout and design. Click here to learn more about iFields.

The Cardknox iFields solution utilizes iFrames in which the user enters their credit card and/or ACH information and then uses JavaScript to generate SUTs (single-use tokens) for processing. These features allow the website to remain secure and out-of-scope for PCI compliance while allowing the developer to customize the page layout and design fully.
