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. 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.

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"
    }
  }'

1.2 Create a Payment

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

Sample Code

The following is a sample API request and response for creating a payment:

Request Parameters

Response Parameters

Descriptions for the response parameters are present in the

Response Types

{
"error_code": "BAD_REQUEST_ERROR",
"error_description": "Payment failed",
"error_source": "gateway",
"error_step": "payment_authorization",
"error_reason": "payment_failed",
}

Know more about

The HTML form returned in the response should be opened in the customer's browser. The customer completes the payment on the displayed page.

1.3 Handle Payment Success and Failure

Once the payment is completed by the customer, a POST request is sent to the callback_url provided in the

Success

A successful payment contains the following fields:

1. razorpay_payment_id
2. razorpay_order_id
3. razorpay_signature

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

Failure

In failed payments, the response received at the callback contains the error details as shown below:

error%5Bcode%5D=BAD_REQUEST_ERROR&error%5Bdescription%5D=Payment+failed&error%5Bsource%5D=gateway&error%5Bstep%5D=payment_authorization&error%5Breason%5D=payment_failed&error%5Bmetadata%5D=%7B%22payment_id%22%3A%22pay_HDP0E0MdoAaOYu%22%2C%22order_id%22%3A%22order_HDOSKuUVbejk0C%22%7D

The key-value parameters of the request are shown below:

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:

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
     Curlec Dashboard
     .

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

   HMAC Hex Digest

   copy

   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.

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

1.5 Verify Payment Status

You can track the payment status in three ways:

• From the Curlec Dashboard

  .

• Subscribe to the webhook event

  .

• Poll our APIs

  .

Verify Status from Dashboard

To verify the payment status from the Dashboard:

1. Log in to the

   Dashboard

   and navigate to Transactions → Payments.
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.

Subscribe to Webhook Events

You can use Curlec webhooks to configure and receive notifications when a specific event occurs. When one of these events is triggered, we send an HTTP POST payload in JSON to the webhook's configured URL. Know how to

Example

If you have subscribed to the order.paid webhook event, you will receive a notification every time a customer pays you for an order.
