1. Build Integration for UPI Collect

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.

Collect Flow Integration

The integration consists of the following steps.

1.1

Create an Order

1.2

Create a Payment

1.3

Handle Payment Success and Failure

1.4

Verify Payment Signature

1.5

Verify Payment Status

Watch Out!

Do not hardcode the URL returned in the API responses.

1.1 Create an Order

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.

Sample Code

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. Know how to
authenticate
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.

API Sample Code

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'
-d '{
   "amount": 100,
   "currency": "MYR",
   "receipt": "qwsaq1",
   "partial_payment": true,
   "first_payment_min_amount": 230,
   "notes": {
     "key1": "value3",
     "key2": "value2"
   }
 }'

Request Parameters

amount

mandatory

integer The amount to be paid by the customer in sen. For example, if the amount is RM 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

optional

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

1.2 Create a Payment

Create a payment using the API given below after your order is created.

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_Ky7GhR2EgoKxOE",
  "email": "gaurav.kumar@example.com",
  "contact": "9090909090",
  "method": "upi",
  "upi":{
      "flow":"collect",
      "vpa":"gauravkumar@okhdfcbank"
  },
  "ip": "192.168.0.103",
  "referer": "http",
  "user_agent": "Mozilla/5.0",
  "description": "Test payment",
  "notes": {
    "note_key": "value1"
  }
}'

{
  "razorpay_payment_id": "pay_ERGVHAXaLNV1y5",
    "next": [
      {
        "action": "poll",
        "url": "https://api.razorpay.com/v1/payments/pay_ERGVHAXaLNV1y5"
      }
    ]
}

Once the payment is successfully created, you will receive a response containing the next array. This array tells you the next steps that you should take to process the payment:

action

string The action that you need to perform further. In this case, the value is poll

url

string Contains the URL that you must poll to fetch the status of the payment, either authorized or failed.

Request Parameters

The payment request for each of the supported payment methods will slightly vary. Know more about the

relevant payment request fields

1.3 Handle Payment Success and Failure

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.

Success Callback

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"
}

Failure Callback

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

errors

for details.

1.4 Verify Payment 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
  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

1.5 Verify Payment Status

Handy Tips

On the Razorpay Curlec 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 Razorpay Curlec Dashboard:

Log in to the Razorpay Curlec 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.
