Magento Plugin

The Magento Cardknox plugin will allow you to charge credit cards via the Cardknox gateway. Cardknox enables credit card payments for both customers on the storefront and for merchants in the Admin portal. The plugin supports Authorize Only, Capture, Void, Cancel, and Refund transactions. As a merchant, your web servers remain out of scope of the transaction, keeping card data secure and simplifying PCI compliance.

Usage

New Order

Select Credit Card as the payment method in the Payment & Shipping Information section (see Title in the Configuration Options section of this document).

Capture

If ‘Authorize’ is selected as the Payment Action in the Cardknox module settings (see Payment Actions in the Configuration Options section of this page), select ‘Capture Online’ to capture the transaction before submitting the invoice. Please note that previously voided transactions cannot be captured and will result in an error.

Void

Use ‘Void’ to cancel transactions on orders that have not yet been invoiced. This is only available if ‘Authorize’ is selected as the Payment Action in the Cardknox module settings (see Payment Actions in the Configuration Options section of this document). Once an order has been invoiced, use ‘Credit Memo’ to refund the transaction.

Please note that ‘Void’ cancels the credit card transaction but does not cancel the order. To cancel the order as well, see the Cancel section below.

Cancel

Use Cancel to void an un-captured transaction and cancel the associated order.

Credit Memo

Issue a Credit Memo to refund an order that has already been invoiced.

Retrieving Cardknox Reference Number

Cardknox transaction reference numbers can be found in the Transaction History section of any order page and are listed as Transaction ID. This can be useful when viewing your transactions on the Cardknox Gateway portal or when contacting Cardknox Support regarding specific transactions.
