PhonePe Switch Integration

Integrate your Razorpay Custom web application to accept payments in PhonePe Switch platform.

PhonePe Switch platform allows customers to switch seamlessly between PhonePe and their preferred apps within the PhonePe app itself. With a single tap, customers can log in to these apps without downloading them. For example, customers can book cabs or hotel rooms right on the PhonePe app and utilize offers provided by PhonePe.

PhonePe enables various businesses to integrate their web apps or mobile sites with the Switch platform and instantly reach out to the PhonePe user base. By integrating Razorpay APIs with PhonePe Switch payment flow, you can accept in-app payments made by your customers without having to worry about handling settlements or reconciliation separately.

Integration Steps

Steps to integrate Custom Checkout in your site:

Step 1: Create an Order in your Server

When a customer places an order on your website or application, use the details to create an order on Razorpay.

POST

/orders

curl -u [YOUR_KEY_ID]:[YOUR_KEY_SECRET] \
-X POST https://api.razorpay.com/v1/orders \
-H "Content-Type: application/json" \
 -d '{
    "amount": 1000,
    "currency": "INR",
    "receipt": "merchant_txn_id"
    "phonepe_switch_context" : "{\n\"orderContext\":{\"trackingInfo\":{\n\"type\":\"HTTPS\",\"url\":\"https://google.com\"}},\"fareDetails\":{\n\"payableAmount\":3900,\"totalAmount\":3900},\"cartDetails\":{\"cartItems\":[{\"quantity\":1,\"address\":{\"addressString\":\"TEST\",\"city\":\"TEST\",\"pincode\":\"TEST\",\"country\":\"TEST\",\n\"latitude\":1,\"longitude\":1},\"shippingInfo\":{\n\"deliveryType\":\"STANDARD\",\"time\":{\"timestamp\":1561540218,\"zoneOffSet\":\"+05:30\"\n\n\n}},\n\n\n\n\n\"category\":\"SHOPPING\",\"itemId\":\"1234567890\",\n\"price\":3900,\"itemName\":\"TEST\"}]}}"
}'

Request Parameters

amount

mandatory

integer The transaction amount, expressed in the currency subunit, such as paise (in case of INR). For example, for an actual amount of ₹299.35, the value of this field should be 29935.

currency

mandatory

string The currency in which the transaction should be made.
You can create Orders in INR only.

receipt

optional

string Your receipt ID for this order can be passed here. Maximum length is 40 characters.

phonepe_switch_context

optional

json string This is the transactionContext created by PhonePe. It contains the shopping cart details for the customer transacting on the PhonePe Switch platform. It is the transactionContext which is expected by PhonePe.
Refer to

PhonePe transactionContext documentation

notes

optional

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”.

Step 2: Invoke Checkout and Pass Order Id and Other Options to it

Step 2.1: Include the JavaScript code in your Webpage

Include the following script, preferably in <head> section of your page:

<script type="text/javascript" src="https://checkout.razorpay.com/v1/razorpay.js"></script>

Including the Javascript, not the Library

Include the script from https://checkout.razorpay.com/v1/razorpay.js instead of serving a copy from your own server. This allows new updates and bug fixes to the library to get automatically served to your application.

We always maintain backward compatibility with our code.

Step 2.2: Instantiate Razorpay Custom Checkout

Single Instance on a Page

var razorpay = new Razorpay({
  key: '<YOUR_KEY_ID>',
    // logo, displayed in the payment processing popup
  image: 'https://i.imgur.com/n5tjHFD.jpg',
});

Multiple Instances on Same Page

If you need multiple razorpay instances on same page, you can globally set some of the options:

Razorpay.configure({
  key: '<YOUR_KEY_ID>',
    // logo, displayed in the payment processing popup
  image: 'https://i.imgur.com/n5tjHFD.jpg',
})
new Razorpay({}); // will inherit key and image from above.

Step 2.3: Submit Payment Details

Once the order is created and the customer's payment details are obtained, the information should be sent to Razorpay to complete the payment. The data that needs to be submitted depends upon the payment method selected by the customer.

You can do this by invoking createPayment method:

var data = {
    amount: 1000, // in currency subunits. Here 1000 = 1000 paise, which equals to ₹10
    currency: "INR",
    email: 'gaurav.kumar@example.com',
    contact: '9123456780',
    notes: {
    address: 'Ground Floor, SJR Cyber, Laskar Hosur Road, Bengaluru',
    },
    order_id: "order_EdUtuxhupLSOUH", // Enter the order ID obtained from Step 1
    method: 'wallet',
    wallet: 'phonepeswitch'
    };

    var btn = document.querySelector('#btn');
    btn.addEventListener('click', function(){
    razorpay.createPayment(data);

    razorpay.on('payment.success', function(resp){
        alert(resp.razorpay_payment_id),
        alert(resp.razorpay_order_id),
        alert(resp.razorpay_signature)
        }); // will pass payment ID, order ID, and Razorpay signature to success handler.

    razorpay.on('payment.error', function(resp){
        alert(resp.error.description)}); // will pass error object to error handler
  });

Note

The createPayment method should be called within an event listener triggered by user action to prevent the popup from being blocked. For example:

$('button').click( function (){ razorpay.createPayment(...) })

Handler Function vs Callback URL

Handler Function:
When you use the handler function, the response object of the successful payment (razorpay_payment_id, razorpay_order_id and razorpay_signature) is submitted to the Checkout Form. You need to collect these and send them to your server.
Callback URL:
When you use a Callback URL, the response object of the successful payment (razorpay_payment_id, razorpay_order_id and razorpay_signature) is submitted to the Callback URL.

Step 3: Store Fields in your 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.

Step 4: Verify the Signature

This is a mandatory step to confirm the authenticity of the details returned to the Checkout form for successful payments.

To verify the razorpay_signature returned to you by the Checkout form:

Create a signature in your server using the following attributes:
- order_id: Retrieve the order_id from your server. Do not use the razorpay_order_id returned by Checkout.
- razorpay_payment_id: Returned by Checkout.
- key_secret: Available in your server. The key_secret that was generated from the
  Razorpay Dashboard
  .

Use the SHA256 algorithm, the razorpay_payment_id and the order_id to construct a 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 form, the payment received is from an authentic source.

Generate Signature on Your Server

Given below is the sample code for payment signature verification:

RazorpayClient razorpay = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]");

String secret = "EnLs21M47BllR3X8PSFtjtbd";

JSONObject options = new JSONObject();
options.put("razorpay_order_id", "order_IEIaMR65cu6nz3");
options.put("razorpay_payment_id", "pay_IH4NVgf4Dreq1l");
options.put("razorpay_signature", "0d4e745a1838664ad6c9c9902212a32d627d68e917290b0ad5f08ff4561bc50f");

boolean status =  Utils.verifyPaymentSignature(options, secret);

Post Signature Verification

After you have completed the integration, you can

set up webhooks

, make test payments, replace the test key with the live key and integrate with other

APIs

Payment Capture Settings

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.

How to Capture Payments

Auto-capture payments (recommended)
Authorized payments can be automatically captured. You can auto-capture all payments
using global settings
on the Razorpay Dashboard.

Watch Out!
Payment capture settings work only if you have integrated with Orders API on your server side. Know more about the
Orders API
.
Manually capture payments
Each authorized payment can also be captured individually. You can manually capture payments using:
- Payment Capture API
- Dashboard

Know more about

Capture Settings for payments

After the integration is complete, a Pay button will appear 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 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.
Due to using test keys, no real money is deducted. This is a simulated transaction.
