Overview
The client required a more advanced Checkout.com payment solution than the default wordpress plugin could provide. The existing plugin lacked webhook support, checkout page customization, real-time payment synchronization, and the ability to display order summaries or applicant information during checkout. To solve these limitations, we developed a custom Gravity Forms Add-on with secure cross-domain payment architecture, real-time webhook handling, and fully customized checkout experiences. The final solution now powers secure payment processing across multiple live platforms with seamless user experience and production-level reliability.
Our Approach
Our approach focused on building a secure, scalable, and fully customizable payment system integrated directly into Gravity Forms workflows.
We engineered a seamless checkout experience featuring real-time webhook synchronization, secure cross-domain transactions, branded checkout interfaces, and 3D Secure authentication handling while maintaining a reliable and frictionless payment process.
