Web SDK

Integrate ReliancePays payments into your frontend application.

Overview

The ReliancePays Web SDK provides a pre-built, customizable payment form that handles card input, validation, 3D Secure authentication, and payment submission. It simplifies PCI compliance by ensuring sensitive card data never touches your servers.

Integration Options

• Server Setup — Create a payment on your server
• Client Integration — Add the payment form to your frontend

How It Works

1. Server-side: Create a payment with confirm: false to get a client_secret
2. Client-side: Initialize the SDK with your publishable key and client secret
3. User: Fills in payment details in the secure form
4. SDK: Handles submission, 3DS authentication, and redirects
5. Server-side: Receive webhook notification of payment result
