How to handle the real payment callbacks in your application

Automatic Premium Database Setup

Once a transaction is authorized inside the active Razorpay checkout sheet, you must register the callback. Below are ready-to-use snippets to verify security signatures and update user premium records dynamically.

Frontend Client Script (HTML/JS) 
<!-- Load Razorpay Checkout Widget script -->
<script src="https://checkout.razorpay.com/v1/checkout.js"></script>
<script>
function triggerProductionPayment(recipientEmail) {
  const options = {
    "key": "rzp_test_SpdPntQvGu7tsc", // Your Razorpay Key ID
    "amount": "9900", // ₹99 represented in paise
    "currency": "INR",
    "name": "Attendy Pro Premium",
    "description": "Lifetime Subscription License",
    "image": "https://play-lh.googleusercontent.com/your-app-icon",
    "prefill": {
      "email": recipientEmail
    },
    "notes": {
      "registered_app_email": recipientEmail
    },
    "theme": {
      "color": "#2563EB"
    },
    // Actual Razorpay handlers to confirm payment status
    "handler": function (response){
      // Obtain authentic gateway values
      const pay_id = response.razorpay_payment_id;
      const order_id = response.razorpay_order_id;
      const signature = response.razorpay_signature;

      console.log("Verified Payment ID:", pay_id);

      // Deliver details to backend server to process database activation safely
      fetch('/api/v1/grant-premium', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({
          email: recipientEmail,
          payment_id: pay_id,
          order_id: order_id,
          signature: signature
        })
      });
    }
  };
  const rzpCheckout = new Razorpay(options);
  rzpCheckout.open();
}
</script>
Express Backend Handler (HMAC Validation) 
const express = require('express');
const crypto = require('crypto');
const app = express();
app.use(express.json());

// Endpoint executing automated user database state change post-verification
app.post('/api/v1/grant-premium', async (req, res) => {
  const { email, payment_id, order_id, signature } = req.body;
  const RAZORPAY_KEY_SECRET = 'your_razorpay_secret_here';

  // Verify Razorpay payload signature to verify the payment is real
  const generatedSignature = crypto
    .createHmac('sha256', RAZORPAY_KEY_SECRET)
    .update(order_id + "|" + payment_id)
    .digest('hex');

  if (generatedSignature !== signature) {
    return res.status(400).json({ error: 'Signature Verification Failed' });
  }

  try {
    // Database Upgrade Query
    // Example (Firebase FireStore):
    // await db.collection('users').doc(email.toLowerCase()).update({ premium: true });
    return res.status(200).json({ message: 'License successfully granted' });
  } catch(error) {
    return res.status(500).json({ error: error.message });
  }
});
