1.3 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

  . 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.

You can create an order:

• Using the sample code on the Razorpay Postman Public Workspace.
• By manually integrating the API sample codes on your server.

Razorpay Postman Public Workspace

You can use the Postman workspace below to create an order:

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": 500,
 "currency": "INR",
 "receipt": "qwsaq1",
 "partial_payment": true,
 "first_payment_min_amount": 230,
 "notes": {
   "key1": "value3",
   "key2": "value2"
 }
}'

{
 "id": "order_IluGWxBm9U8zJ8",
 "entity": "order",
 "amount": 5000,
 "amount_paid": 0,
 "amount_due": 5000,
 "currency": "INR",
 "receipt": "rcptid_11",
 "offer_id": null,
 "status": "created",
 "attempts": 0,
 "notes": [],
 "created_at": 1642662092
}

1.4 Fetch Payment Methods

You can accept payments through UPI, credit and debit cards, netbanking and wallets, as per the methods enabled on your account.

• When you use Razorpay React Native Standard SDK, you do not have to handle the availability of different payment methods.
• When creating a Custom checkout form, you must ensure that only the methods activated for your account are displayed to the customer. To get a list of available payment methods, call getPaymentMethods. This fetches the list of payment methods asynchronously and returns the result in JSON format in the onPaymentMethodsReceived callback.

Sample Code

The following API is used to fetch all enabled payment methods for a given API Key ID:

https://api.razorpay.com/v1/methods?key_id=[Your_Key_ID]

razorpay.getPaymentMethods(new PaymentMethodsCallback() {
	@Override
	public void onPaymentMethodsReceived(String result) {
		JSONObject paymentMethods = new JSONObject(result);
	}

	@Override
	public void onError(String error){

	}
	});
});

1.5 Import Razorpay Module

Import Razorpay module to your component:

import Razorpay from 'react-native-customui';

1.6 Add Razorpay Checkout Options to app.js File

Call the Razorpay.open method with the payment options. The method returns a JS Promise, where:

• The then part corresponds to a successful payment.
• The catch part corresponds to payment failure.

<TouchableHighlight onPress={() => {
  var options = {
    description: 'Credits towards consultation',
    currency: 'INR',
    key_id: '<YOUR_KEY_ID>',
    amount: '5000',
    email: 'gaurav.kumar@example.com',
    contact: '9999999123',
    method: 'netbanking',
    bank: 'HDFC'

  }
  Razorpay.open(options).then((data) => {
    // handle success
    alert(`Success: ${data.razorpay_payment_id}`);
  }).catch((error) => {
    // handle failure
    alert(`Error: ${error.code} | ${error.description}`);
  });
}}>

Checkout Parameters

1.7 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.

1.8 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
     Razorpay 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

If you use M1 MacBook, you need to make the following changes in your podfile.

installer.pods_project.build_configurations.each do |config|
  config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
end

1.9 Verify Payment Status

You can track the payment status in three ways:

Verify Status from Dashboard

Subscribe to Webhook Events

Poll APIs

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.
