Credit card configuration

The screenshot and the table below it describe your options for setting credit card configurations. The blue highlighted fields in the screenshot below show that you can select multiple items.

Credit card configuration	Description
Enabled	When set to Yes, credit card payments are available to shoppers at checkout.
Title	The title that appears above the credit card payment section at checkout.
Integration mode 1*	Direct integration mode Card information is saved at the Magento online store and passed to Worldpay by server-to-server transfer in XML format. The Worldpay plugin does not saved any card information. This integration requires the highest level of PCI DSS compliance.
Integration mode 2*	Redirect integration mode The shopper is redirected to the Worldpay payment page, and their card information is captured at the Worldpay end. This integration requires the lowest level of PCI DSS compliance.
Payment Methods	Select which credit cards are available to shoppers at checkout.
Client Side Encryption Enabled	If enabled, all card details are securely transferred to Worldpay in encrypted format. This is only required when using the direct integration mode. Using CSE with direct integration reduces the level of PCI DSS compliance that is required.
Public Key	Only required if client-side encryption is enabled. You can get this key from the Worldpay Merchant Admin Interface. If you do not see the option for it, contact your Worldpay representative for help.
Require CVC	If enabled, a mandatory CVC form field appears in the card-detail entry form.

* There are two integration modes for credit cards.

Order notifications

Order notifications are transaction-status updates that Worldpay pushes to the Magento store.

To enable your Magento store to receive order notifications, you must enter the URL below in your Worldpay merchant profile :

https://<brand url>/worldpay/notification/index

Note

You must set up order notifications to make sure this plugin works properly.

If transactions are processed asynchronously, you may notice some details of the transaction among your Magento order details.

The fully updated order details (Sales/Orders/Order View/Information) appear after Magento has received the order notification from Worldpay. Under Payment Information you should see:

Intelligent Account Verification (IAV)

Intelligent Account Verification (IAV) is a feature that validates credit cards.

Cardholders submit a zero or nominal value (a payment with a value greater than zero) while Worldpay determine the amount with the best chance of approval. Any value above zero is automatically reversed.

The processing of a nominal value (or zero) is an important way to verify that an account is real and set up for transactions. Contact Worldpay Support to enable IAV for your company or organization.
