Order creation, payment verification, webhook handler — production-ready Next.js route handlers.

Payment Button Component

Drop-in React component with loading states, error handling, and success callbacks.

TypeScript Types

Tech Stack

Next.js 14+ (App Router, Route Handlers)
TypeScript (strict mode compatible)
Razorpay SDK (razorpay + razorpay-react)
INR / UPI / Cards / Netbanking — all payment methods supported

Prerequisites

Node.js 18+ and npm/pnpm
Next.js 14+ project with App Router
Razorpay account (free to create, pay only transaction fees)
Basic understanding of API routes and React state

02 Setup Guide

Step 1 — Create a Razorpay Account

Go to razorpay.com and click "Sign Up"
Enter your business email, set a password
Complete KYC: PAN, Aadhaar, bank account details
Account activates in 2–3 business days (test mode works instantly)

ℹ️ Test Mode You can start integrating immediately in test mode. No KYC needed for test keys.

Step 2 — Get API Keys

Log into Razorpay Dashboard → Settings → API Keys
Click "Generate Key Pair"
Copy the Key ID (starts with rzp_test_) and Key Secret
For live: repeat with Key ID starting rzp_live_

⚠️ Keep Key Secret safe Never commit it to git. Never expose it in client-side code. It stays server-side only.

Step 3 — Install Dependencies

Terminal

# Using npm
npm install razorpay

# Using pnpm
pnpm add razorpay

# Using yarn
yarn add razorpay

Step 4 — Environment Variables

Copy the .env.example file from the code section below to .env.local in your project root and fill in your keys.

.env.local

# Razorpay
RAZORPAY_KEY_ID=rzp_test_xxxxxxxxxxxxx
RAZORPAY_KEY_SECRET=xxxxxxxxxxxxxxxxxxxxxxxx
RAZORPAY_WEBHOOK_SECRET=your_webhook_secret_here

04 Integration Guide

Product Page — One-time Payment

Use PaymentButton directly. Pass amount in INR (no paise conversion needed — the component handles it).

app/product/[id]/page.tsx

import PaymentButton from "@/components/PaymentButton";

export default function ProductPage() {
  return (
    <div>
      <h1>My Awesome Product</h1>
      <p>₹999 — Lifetime access</p>
      <PaymentButton
        amount={999}
        name="My Awesome Product"
        onSuccess={(res) => {
          window.location.href = `/success?order=${res.razorpay_order_id}`;
        }}
      />
    </div>
  );
}

Course / Subscription Payment

Pass additional notes for tracking. Use the webhook to grant access after confirmation.

components/CourseEnroll.tsx

"use client";
import { useState } from "react";
import PaymentButton from "@/components/PaymentButton";

export default function CourseEnroll({ courseId, price }: { courseId: string; price: number }) {
  const [status, setStatus] = useState<"idle" | "success">("idle");

  if (status === "success") {
    return <p>🎉 Enrollment confirmed! Check your email.</p>;
  }

  return (
    <PaymentButton
      amount={price}
      name="Course Enrollment"
      onSuccess={async () => {
        // Webhook handles actual enrollment
        setStatus("success");
      }}
      onError={(msg) => alert(msg)}
    />
  );
}

Refund Handling

Process refunds via Razorpay Dashboard or API. The webhook (refund.created) auto-catches it.

Server-side refund (optional)

import razorpay from "@/lib/razorpay";

// Partial refund
await razorpay.payments.refund("pay_xxxxx", {
  amount: 50000, // ₹500 in paisa
  notes: { reason: "Customer request" },
});

// Full refund
await razorpay.payments.refund("pay_xxxxx");

05 Common Issues & Fixes

Issue	Cause	Fix
CORS error on checkout	Razorpay script not loaded	Add `<script src="https://checkout.razorpay.com/v1/checkout.js">` in `layout.tsx` or load it dynamically before checkout
Webhook not receiving events	Wrong URL or not publicly accessible	Use ngrok for local testing. Ensure URL ends with `/api/razorpay/webhook`. Check webhook secret matches env var.
Payment captured but order not updated	Webhook didn't fire or handler threw	Check Razorpay Dashboard → Webhooks → Logs. Add error logging in webhook handler. Re-trigger from dashboard.
Test vs live key confusion	Using live key in dev or test key in prod	Use `NODE_ENV` to switch, or separate env files. Test keys = `rzp_test_`, live = `rzp_live_`
"Unauthorized" on order creation	Missing or wrong key secret	Double-check `RAZORPAY_KEY_SECRET` in `.env.local`. No trailing spaces.
Signature mismatch on verify	Secret mismatch or body tampered	Ensure `RAZORPAY_KEY_SECRET` is identical to dashboard. Verify body isn't modified between receipt and verification.

⚠️ UPI payments UPI transactions may take 2–3 seconds longer to confirm. Don't mark as failed immediately — the webhook will fire when the bank confirms.

06 Checklists

Pre-Launch Checklist

All API routes return proper error responses (not 500 stack traces)
Payment verification runs server-side (never trust client alone)
Webhook signature verification is active
Amount validation prevents zero/negative/overflow amounts
Environment variables are in .env.local, not committed to git
Razorpay script loaded before checkout opens
Test with all payment methods: UPI, cards, netbanking
Test failed payment flow (use test card 4111 1111 1111 1111)
Test payment dismissed by user (modal closed without paying)
Idempotency: duplicate webhook calls don't double-charge or double-fulfill

Go-Live Checklist

Switch from test to live keys in environment variables
Update webhook URL in Razorpay Dashboard to production domain
Verify webhook secret matches production env var
Enable live payment methods in Dashboard (UPI, Cards, Netbanking, Wallets)
Test one real ₹1 transaction end-to-end
Verify email notifications fire on payment.captured
Check Razorpay Dashboard for successful webhook delivery
Set up Razorpay payout schedule for your bank account
Monitor first 24 hours for failed webhooks or signature errors
