Description
The gf-worldpay plugin by Itineris Ltd is a Gravity Forms add-on that integrates the WorldPay payment gateway with WordPress sites, enabling secure payment processing through Gravity Forms. It relies on WorldPay’s HTML API and requires careful setup, including enabling payment responses, setting MD5 secrets, and payment response passwords to protect against fraudulent activity. The plugin supports logging, notification events, confirmations, and Gravity Forms conditional logic, providing a robust integration for payment workflows.
This add-on focuses on one-time payment transactions and does not support features like shipping address collection, token payments, recurring billing, refunds, or voids. The plugin emphasizes security measures such as using HTTPS and validating payment callbacks to prevent unauthorized or fake transactions.
