1. Build Integration for UPI Intent

Steps to integrate S2S JSON V1 and accept payments using UPI Intent.


In case of UPI as there is no redirect involved when the customer completes the payment, you should keep polling Razorpay APIs to get the latest status of the payment.

The integration consists of the following steps.

Watch Out!

Do not hardcode the URL returned in the API responses.

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. It is a server-side API call.
  • The order_id received in the response should be passed to the checkout.

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

Use this endpoint to create an order using the Orders API.

POST
/orders
curl -X POST https://api.razorpay.com/v1/orders
-U [YOUR_KEY_ID]:[YOUR_KEY_SECRET]
-H 'content-type:application/json'

Request Parameters

amount

mandatory

integer The amount to be paid by the customer in sen. For example, if the amount is MYR 500.00, enter 50000.

currency

mandatory

string The currency in which the payment should be made by the customer. Length must be of 3 characters.

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

For example, if an amount of MYR 7,000.00 is to be received from the customer in two installments of #1 - MYR 5,000.00, #2 - MYR 2,000.00 then you can set this value as 500000. This parameter should be passed only if partial_payment is true.

Once an order is created, your next step is to create a payment.

The following API will create a payment with upi with intent flow.

POST
/payments/create/json
curl -u [YOUR_KEY_ID]:[YOUR_KEY_SECRET] \
-X POST https://api.razorpay.com/v1/payments/create/json \
-H "Content-Type: application/json" \
-d '{
"amount": 100,
"currency": "INR",
"order_id": "order_Ky7DOsYy3TVfLS",
"email": "gaurav.kumar@example.com",
"contact": "9090909090",
"method": "upi",
"upi":{
"flow":"intent"
},
"ip": "192.168.0.103",
"referer": "http",
"user_agent": "Mozilla/5.0",
"description": "Test payment",
"notes": {
"note_key": "value1"
}
}'

The next array contains the following objects:

action

string The action you need to perform next. In this case, the value is intent.

url

string Contains the URL that the customer should be redirected. This is commonly done by rendering the URL returned by Razorpay in the form of a button or a link for the customer to use.

action

string The action that you need to take to fetch the status of the payment. In this case the value is poll.

url

string Contains the URL that you need to keep polling to fetch the status of the payment, either authorized or failed.

Once the payment is completed by the customer, a POST request is made to the callback_url provided in the payment request. The data contained in this request will depend on whether the payment was a success or a failure of the payment made by the customer.

If the payment made by the customer is successful, the following fields are sent:

  • razorpay_payment_id
  • razorpay_order_id
  • razorpay_signature
{
"razorpay_payment_id": "pay_29QQoUBi66xm2f",
"razorpay_order_id": "order_9A33XWu170gUtm",
"razorpay_signature": "9ef4dffbfd84f1318f6739a3ce19f9d85851857ae648f114332d8401e0949a3d"
}

If the payment has failed, the callback will contain details of the error. Refer to

for details.

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:

  1. 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 .
  2. 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
    }
  3. 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.

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);

After you have completed the integration, you can

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

Handy Tips

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

.

You can track the payment status in three ways:

To verify the payment status from the Dashboard:

  1. Log in to the and navigate to TransactionsPayments.
  2. 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
