Integrate a hosted payment form

This guide describes how to integrate a hosted payment form into your website.

Hosted payment forms simplify the process of accepting payments. Rebilly hosts your payment forms and ensures that your payments process is secure and PCI-compliant.

Use payment forms to process payments from your customers. To interact with an example hosted payment form, see Interactive example.

To complete this tutorial, an active gateway is required. If you are testing in the sandbox environment, a test payment gateway called TestProcessor is already configured. For more information, see Set up a payment gateway.

Prerequisites

These resources and details are required to complete this guide using your Rebilly sandbox environment. If you have already created these resources, skip this step and continue to Set up a hosted payment form.

If this value is included in the response, redirect the client to the URL to complete the payment.

If this value is not returned, send the transaction details back to the client.

server.js

Listen for requests

Start an Express server on port 8080, listen for host and port information from the server, and log a messages to the console.

server.js

Set up the HTML page
