Integrate With Razorpay Payment Gateway

Start accepting domestic and international payments from customers on your website using the Razorpay Payment Gateway. Razorpay has developed the Standard Checkout method and manages it. You can configure payment methods, orders, company logo and also select custom colour based on your convenience. Razorpay supports these

payment methods

and

international currencies

Configure node.js integrated payment gateway checkout based on your requirement

Watch this video to know how to integrate Razorpay Payment Gateway on your Node.js app. We recommend you check the

Razorpay Node.js Sample App

, created using the video tutorial.

GitHub Repository

Download the latest

razorpay-node.zip

file from GitHub. It is pre-compiled to include all dependencies.

Project Structure

Before you begin, we recommend you check the

Razorpay Node.js Sample App

, (created using the

Video Tutorial

), and verify that your project contains the following files:

Before you proceed:

Create a
Razorpay account
.
Log in to the Razorpay Dashboard and
generate the API keys
in test mode.
Know about the
Razorpay Payment Flow
and follow these integration steps:

1. Build Integration

Integrate with your Node.js-based website.

2. Test Integration

Test the integration by making a test payment.

3. Go-live Checklist

Check the go-live checklist.

1. Build Integration

1.1 Instantiate Razorpay

In your server file, instantiate the Razorpay instance with your key_id and key_secret. You should generate the API keys on the Razorpay Dashboard and add them here.

Given below is the command:

var instance = new Razorpay({
  key_id: 'YOUR_KEY_ID',
  key_secret: 'YOUR_KEY_SECRET',
});

The resources can be accessed using the instance. All the methods invocations follow the namespaced signature:

// API signature
// {razorpayInstance}.{resourceName}.{methodName}(resourceId [, params])
// example

instance.payments.fetch(paymentId)

Every resource method returns a promise.

instance.payments.all({
  from: '2016-08-01',
  to: '2016-08-20'
}).then((response) => {
  // handle success
}).catch((error) => {
  // handle error
})

If you want to use callbacks instead of promises, every resource method accepts a callback function as the last parameter. The callback function acts as Error First Callbacks.

instance.payments.all({
  from: '2016-08-01',
  to: '2016-08-20'
}, (error, response) => {
  if (error) {
    // handle error
  } else {
    // handle success
  }
})

1.2 Create an Order in Server

Order is an important step in the payment process.

An order should be created for every payment.
You can create an order using the
Orders API
in the app.js file. It is a server-side API call. Know how to
authenticate
Orders API.
The order_id received in the response should be passed to checkout in the index.html file. This ties the Order with the payment and secures the request from being tampered.

Handy Tips

You can capture payments automatically with one-time

Payment Capture setting configuration

on the Razorpay Dashboard.

1.2.1 Sample Code

In the sample app, the app.js file contains the code for order creation using Orders API.

const Razorpay = require('razorpay');
var instance = new Razorpay({ key_id: 'YOUR_KEY_ID', key_secret: 'YOUR_SECRET' })

var options = {
  amount: 50000,  // amount in the smallest currency unit
  currency: "INR",
  receipt: "order_rcptid_11"
};
instance.orders.create(options, function(err, order) {
  console.log(order);
});

1.2.2 Request Parameters

Here is the list of parameters for creating an order:

amount

mandatory

integer Payment amount in the smallest currency sub-unit. For example, if the amount to be charged is ₹299.00, then pass 29900 in this field. In the case of three decimal currencies, such as KWD, BHD and OMR, to accept a payment of 295.991, pass the value as 295990. And in the case of zero decimal currencies such as JPY, to accept a payment of 295, pass the value as 295.

Watch Out!

As per payment guidelines, you should pass the last decimal number as 0 for three decimal currency payments. For example, if you want to charge a customer 99.991 KD for a transaction, you should pass the value for the amount parameter as 99990 and not 99991.

currency

mandatory

string The currency in which the transaction should be made. See the

list of supported currencies

. Length must be 3 characters.

Handy Tips

Razorpay has added support for zero decimal currencies, such as JPY, and three decimal currencies, such as KWD, BHD, and OMR, allowing businesses to accept international payments in these currencies. Know more about

receipt

optional

string Your receipt id for this order should be passed here. Maximum length is 40 characters.

notes

optional

json object Key-value pair that can be used to store additional information about the entity. Maximum 15 key-value pairs, 256 characters (maximum) each. For example, "note_key": "Beam me up Scotty”.

partial_payment

optional

boolean Indicates whether the customer can make a partial payment. Possible values:

true: The customer can make partial payments.
false (default): The customer cannot make partial payments.

first_payment_min_amount

optional

integer Minimum amount that must be paid by the customer as the first partial payment. For example, if an amount of ₹7,000.00 is to be received from the customer in two installments of #1 - ₹5,000.00, #2 - ₹2,000.00 then you can set this value as 500000. This parameter should be passed only if partial_payment is true.

1.3.4 Handle Payment Success and Failure

The way the Payment Success and Failure scenarios are handled depends on the

Checkout Sample Code

you used in the last step.

Checkout with Callback URL

If you used the sample code with the callback URL:

Razorpay makes a POST call to the callback URL with the razorpay_payment_id, razorpay_order_id and razorpay_signature in the response object of the successful payment. Only successful authorisations are auto-submitted.

Checkout with Handler Function

If you used the sample code with the handler function:

The customer sees your website page. The checkout returns the response object of the successful payment (razorpay_payment_id, razorpay_order_id and razorpay_signature). Collect these and send them to your server.

Use the Success/Failure Handling code given below:

"handler": function (response){
    alert(response.razorpay_payment_id);
    alert(response.razorpay_order_id);
    alert(response.razorpay_signature)}

1.3.5 Configure Payment Methods (Optional)

Multiple payment methods are available on Razorpay Standard Checkout.

The payment methods are fixed and cannot be changed.
You can configure the order or make certain payment methods prominent. Know more about configuring payment methods. Know more about
configuring payment methods
.

1.4 Store Fields in Server

A successful payment returns the following fields to the Checkout form.

You need to store these fields in your server.
You can confirm the authenticity of these details by verifying the signature in the next step.

razorpay_payment_id

string Unique identifier for the payment returned by Checkout only for successful payments.

razorpay_order_id

string Unique identifier for the order returned by Checkout.

razorpay_signature

string Signature returned by the Checkout. This is used to verify the payment.

1.5 Verify Payment Signature

This is a mandatory step that allows you to confirm the authenticity of the details returned to the checkout for successful payments.

To verify the razorpay_signature returned to you by the checkout:

Create a signature in your server using the following attributes:

Use the SHA256 algorithm, the razorpay_payment_id and the order_id to construct an HMAC hex digest as shown below:

generated_signature = hmac_sha256(order_id + "|" + razorpay_payment_id, secret);

    if (generated_signature == razorpay_signature) {
    payment is successful
     }

If the signature you generate on your server matches the razorpay_signature returned to you by the checkout, the payment received is from an authentic source.

Use the code given below to generate signature on your server:

var instance = new Razorpay({ key_id: 'YOUR_KEY_ID', key_secret: 'YOUR_SECRET' })

var { validatePaymentVerification, validateWebhookSignature } = require('./dist/utils/razorpay-utils');
validatePaymentVerification({"order_id": razorpayOrderId, "payment_id": razorpayPaymentId }, signature, secret);

Add the following code in the front-end:

var settings = {
  "url": "/api/payment/verify",
  "method": "POST",
  "timeout": 0,
  "headers": {
   "Content-Type": "application/json"
  },
  "data": JSON.stringify({response}),
}

1.6 Verify Payment Status

Handy Tips

On the Dashboard, ensure that the payment status is captured. Refer to the payment capture settings page to know how to

capture payments automatically

You can track the payment status in three ways:

To verify the payment status from the Dashboard:

Log in to the
Dashboard
and navigate to Transactions → Payments.
Check if a Payment Id has been generated and note the status. In case of a successful payment, the status is marked as Captured.

Check if the payment id is generated and the status is captured

2. Test Integration

After the integration is complete, a Pay button appears on your webpage/app.

Click the button and make a test transaction to ensure the integration is working as expected. You can start accepting actual payments from your customers once the test transaction is successful.

You can make test payments using one of the payment methods configured at the Checkout.

Watch Out!

This is a mock payment page that uses your test API keys, test card and payment details.

Ensure you have entered only your
Test Mode API keys
in the Checkout code.
No real money is deducted due to the usage of test API keys. This is a simulated transaction.

Supported Payment Methods

Following are all the payment modes that the customer can use to complete the payment on the Checkout. Some of them are available by default, while others require approval from us. Raise a request from the

Dashboard

to enable such payment methods.

Netbanking

You can select any of the listed banks. After choosing a bank, Razorpay will redirect to a mock page where you can make the payment success or a failure. Since this is Test Mode, we will not redirect you to the bank login portals.

Check the list of

supported banks

UPI

You can enter one of the following UPI IDs:

success@razorpay: To make the payment successful.
failure@razorpay: To fail the payment.

Check the list of

supported UPI flows

Handy Tips

You can use Test Mode to test UPI payments, and Live Mode for UPI Intent and QR payments.

Cards

You can use one of the following test cards to test transactions for your integration in Test Mode.

Use any valid expiration date in the future in the MM/YY format.
Use any random CVV to create a successful payment.

Check the list of

supported card networks

Wallet

You can select any of the listed wallets. After choosing a wallet, Razorpay will redirect to a mock page where you can make the payment success or a failure. Since this is Test Mode, we will not redirect you to the wallet login portals.

Check the list of

supported wallets

3. Go-live Checklist

Check the go-live checklist for Razorpay Web Standard Checkout integration. Consider these steps before taking the integration live.

3.1 Accept Live Payments

You can perform an end-to-end simulation of funds flow in the Test Mode. Once confident that the integration is working as expected, switch to the Live Mode and start accepting payments from customers.

Watch Out!

Ensure you are switching your test API keys with API keys generated in Live Mode.

To generate API Keys in Live Mode on your Razorpay Dashboard:

Log in to the
Razorpay Dashboard
and switch to Live Mode on the menu.
Navigate to Account & Settings → API Keys → Generate Key to generate the API Key for Live Mode.
Download the keys and save them securely.
Replace the Test API Key with the Live Key in the Checkout code and start accepting actual payments.

3.2 Payment Capture

After payment is authorized, you need to capture it to settle the amount to your bank account as per the settlement schedule. Payments that are not captured are auto-refunded after a fixed time.

Watch Out

You should deliver the products or services to your customers only after the payment is captured. Razorpay automatically refunds all the uncaptured payments.
You can track the payment status using our
Fetch a Payment API
or webhooks.

Authorized payments can be automatically captured. You can auto-capture all payments

using global settings

on the Razorpay Dashboard. Know more about

capture settings for payments

Watch Out!

Payment capture settings work only if you have integrated with Orders API on your server side. Know more about the

Orders API

3.3 Set Up Webhooks

Ensure you have

set up webhooks

in the live mode and configured the events for which you want to receive notifications.

Integrate With Other Razorpay Products

Razorpay offers a range of

payment products

to meet your business requirements. Visit our

GitHub repository

for the sample codes.

Partner Authentication

If you are a partner and want to use the API as a particular merchant, you must authenticate your account by passing an additional header X-Razorpay-Account with the merchant account_id as the value.

Example

var instance = new Razorpay({
  key_id: '<your_partner_key>',
  key_secret: '<your_partner_secret>',
  headers: {
    "X-Razorpay-Account": "<merchant_account_id>"
  }
});

instance.orders.all().then(console.log).catch(console.error);
