Razorpay Guide

End-to-end guide for integrating Razorpay with PayKit — covering order creation, modal-based checkout, supported payment methods, and webhook verification.

Installation

Install the core PayKit package along with the Razorpay adapter:

Terminal

npm install @squaredr/paykit razorpay

Backend Setup

Import PayKit and the Razorpay adapter, then initialise the client with your Razorpay key ID and key secret:

src/lib/paykit.ts

import { PayKit } from '@squaredr/paykit'
import { RazorpayAdapter } from '@squaredr/paykit/razorpay'

const paykit = new PayKit({
  adapter: new RazorpayAdapter({
    keyId: process.env.RAZORPAY_KEY_ID!,
    keySecret: process.env.RAZORPAY_KEY_SECRET!,
  }),
})

Creating an Order

Razorpay uses an order-based payment flow. You first create an order on the server, then the customer authorises the payment on the frontend. The clientSecret returned by PayKit contains the Razorpay order_id needed for the frontend SDK.

Amounts must be specified in paise (the smallest currency unit for INR). For example, 50000 represents ₹500.00.

src/app/api/checkout/route.ts

import { paykit } from '@/lib/paykit'

export async function POST(request: Request) {
  const { amount, orderId } = await request.json()

  const charge = await paykit.charges.create({
    amount,        // amount in paise, e.g. 50000 = ₹500
    currency: 'inr',
    metadata: { orderId },
  })

  return Response.json({ clientSecret: charge.clientSecret })
}

Frontend (React)

Wrap your checkout page with PayKitProvider and render the CheckoutForm. The RazorpayClientAdapter opens Razorpay's modal-based checkout overlay automatically when the customer submits the form.

src/components/Checkout.tsx

'use client'

import {
  PayKitProvider,
  CheckoutForm,
} from '@squaredr/paykit-react'
import { RazorpayClientAdapter } from '@squaredr/paykit/razorpay/client'

const razorpayAdapter = new RazorpayClientAdapter({
  keyId: process.env.NEXT_PUBLIC_RAZORPAY_KEY_ID!,
})

export default function Checkout({
  clientSecret,
}: {
  clientSecret: string
}) {
  return (
    <PayKitProvider
      adapter={razorpayAdapter}
      clientSecret={clientSecret}
    >
      <CheckoutForm
        onSuccess={(result) => {
          console.log('Payment succeeded:', result.id)
        }}
        onError={(err) => {
          console.error('Payment failed:', err.message)
        }}
      />
    </PayKitProvider>
  )
}

Note: Razorpay uses a modal-based checkout flow rather than inline card fields. The modal is managed by the Razorpay SDK and opened automatically by the adapter.

Frontend (Vanilla JS)

Use the imperative PayKitClient API to trigger Razorpay's modal checkout without React:

src/checkout.ts

import { PayKitClient } from '@squaredr/paykit-js'
import { RazorpayClientAdapter } from '@squaredr/paykit/razorpay/client'

const pk = new PayKitClient({
  adapter: new RazorpayClientAdapter({
    keyId: 'rzp_test_...',
  }),
})

async function checkout(clientSecret: string) {
  const result = await pk.confirmPayment({
    clientSecret,
    metadata: {
      name: 'Jane Doe',
      email: 'jane@example.com',
      contact: '+919876543210',
    },
  })

  if (result.error) {
    console.error(result.error.message)
  } else {
    console.log('Payment confirmed:', result.payment.id)
  }
}

Payment Methods

Razorpay supports a broad range of payment methods popular in India:

Cards — Visa, Mastercard, RuPay, American Express, Diners Club
Netbanking — 50+ banks including SBI, HDFC, ICICI, Axis, and Kotak
UPI — Google Pay, PhonePe, Paytm, BHIM, and other UPI apps
Wallets — Paytm, Mobikwik, Freecharge, Amazon Pay, and more
EMI — Card-based and cardless EMI options from major banks

Webhooks

Use the Razorpay adapter's webhooks.construct method to verify the x-razorpay-signature header and safely parse incoming events:

src/app/api/webhooks/razorpay/route.ts

import { paykit } from '@/lib/paykit'

export async function POST(request: Request) {
  const payload = await request.text()
  const signature = request.headers.get('x-razorpay-signature')!
  const secret = process.env.RAZORPAY_WEBHOOK_SECRET!

  const event = paykit.webhooks.construct({
    payload,
    signature,
    secret,
  })

  switch (event.type) {
    case 'payment.succeeded':
      // fulfil the order
      break
    case 'payment.failed':
      // notify the customer
      break
    case 'refund.created':
      // update records
      break
  }

  return new Response('ok', { status: 200 })
}

Test Credentials

Use the following credentials in Razorpay's test mode to simulate payment scenarios:

Cards

Field	Value
Card Number	`4111 1111 1111 1111`
CVV	Any 3 digits
Expiry	Any future date
OTP	`0007`

UPI

Use success@razorpay as the VPA for a successful UPI payment simulation.

Netbanking

Use test / test as the username and password when redirected to the test bank page.

For the full list of test credentials, see the Razorpay testing documentation.
