Razorpay Integration POC

This project is a Proof of Concept (POC) for integrating Razorpay, a popular payment gateway, with an Express.js application. The project demonstrates the basic setup and usage of Razorpay's APIs to handle payment processing, order creation, and webhook verification.

Features

• Integration with Razorpay for payment processing
• Creating and managing orders
• Handling payment callbacks and webhooks
• Storing order information locally in a JSON file

Installation and Setup

1. Clone the repository:

   git clone https://github.com/Salmandabbakuti/razorpay-integration-poc.git
   cd razorpay-integration-poc

2. Install dependencies:

   npm install

3. Configure your Razorpay credentials:

   • Obtain your API key and secret from the Razorpay dashboard.
   • Create a .env file in the root directory and add your credentials:

RAZORPAY_KEY_ID=your_key_id
RAZORPAY_KEY_SECRET=your_key_secret
RAZORPAY_WEBHOOK_SECRET=your_webhook_secret

4. Start the application:

   npm start

API Endpoints

Create Order

Endpoint: POST /create-order Description: Creates a new order in Razorpay and stores the order details locally. Payload:

{
  "amount": 500,
  "currency": "INR"
}

Verify Payment

Endpoint: POST /verify-payment Description: Verifies the payment using Razorpay's webhook signature and updates the order status. Payload:

{
  "razorpay_order_id": "order_id",
  "razorpay_payment_id": "payment_id",
  "razorpay_signature": "signature"
}

Usage

1. Create an order:

   const orderOptions = {
     amount: 50000, // amount in paise
     currency: "INR",
     receipt: "order_rcptid_11",
     notes: {
       userId: "123",
       plan: "basic",
       email: "[email protected]"
     }
   };
   
   const response = await razorpay.orders.create(orderOptions);
   console.log(response);

2. Verify payment:

   const isValidSignature = validateWebhookSignature(body, razorpay_signature, RAZORPAY_KEY_SECRET);
   if (isValidSignature) {
     console.log("Payment verification successful");
   } else {
     console.log("Payment verification failed");
   }
