React Native Version 0.60+:
This document elaborates the SDK integration steps for apps running on React Native version 0.60+. You can find the SDK integration steps for apps with React Native version 0.59 and lower on GitHub.

Integration Steps#

Steps to integrate Razorpay React Native SDK for Android.

  1. Install Razorpay React Native SDK.
  2. Import Razorpay Package in MainApplication.java.
  3. Add Razorpay SDK in Settings Gradle File.
  4. Add Dependency in App Build Gradle File.
  5. Run React Native App.
  6. Create an Order in Server.
  7. Add Razorpay Checkout Options to app.js File.
  8. Store Fields in Server.
  9. Verify Payment Signature.

Post-Integration Steps:
Once you have successfully completed the integration, you can setup webhooks, make test payments, replace test key with live key and integrate with other APIs. Refer to the Test the Integration section for more details.

Step 1: Install Razorpay React Native SDK#

Install the SDK using the following npm command in the Terminal window. If you are using Windows, please use Git Bash instead of Command Prompt window. Ensure that you run this code within your React Native project folder in Terminal window.

Copy$ npm install react-native-razorpay --save

Step 2: Import Razorpay Package in MainApplication.java#

Launch Android Studio and open the MainAplication.java file from your project folder. Add the following code:

Copyimport com.razorpay.rn.RazorpayPackage;

Also, add new RazorpayPackage() to the list returned by the getPackages() method.

Copy protected List<ReactPackage> getPackages() { @SuppressWarnings("UnnecessaryLocalVariable") List<ReactPackage> packages = new PackageList(this).getPackages(); // Packages that cannot be autolinked yet can be added manually here, for example: packages.add(new RazorpayPackage()); return packages; }

Step 3: Add Razorpay SDK in Settings Gradle File#

Append the following lines to the settings.gradle file.

Copyinclude ':react-native-razorpay' project(':react-native-razorpay').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-razorpay/android')

Step 4: Add Dependency in App Build Gradle File#

Add the following lines in the dependencies section of your app's build.gradle file.

Copyimplementation project(':react-native-razorpay')

Step 5: Run React Native App#

Run the React Native app.

Copynpx react-native run-android

This links the SDK with your React Native project.

Step 6: Create an Order in Server#

Use the below endpoint to create an Order.

/orders
Copycurl -X POST https://api.razorpay.com/v1/orders -H 'content-type:application/json' -d '{ "amount": 50000, "currency": "INR", "receipt": "rcptid_11" }'
Copytry { JSONObject orderRequest = new JSONObject(); orderRequest.put("amount", 50000); // amount in the smallest currency unit orderRequest.put("currency", "INR"); orderRequest.put("receipt", "order_rcptid_11"); Order order = razorpay.Orders.create(orderRequest); } catch (RazorpayException e) { // Handle Exception System.out.println(e.getMessage()); }
Copyorder_amount = 50000 order_currency = 'INR' order_receipt = 'order_rcptid_11' notes = {'Shipping address': 'Bommanahalli, Bangalore'} # OPTIONAL client.order.create(amount=order_amount, currency=order_currency, receipt=order_receipt, notes=notes)
Copy$order = $client->order->create([ 'receipt' => 'order_rcptid_11', 'amount' => 50000, // amount in the smallest currency unit 'currency' => 'INR',// <a href="/docs/payment-gateway/payments/international-payments/#supported-currencies" target="_blank">See the list of supported currencies</a>.) ]);
CopyDictionary<string, object> options = new Dictionary<string,object>(); options.Add("amount", 50000); // amount in the smallest currency unit options.add("receipt", "order_rcptid_11"); options.add("currency", "INR"); Order order = client.Order.Create(options);
Copyoptions = amount: 50000, currency: 'INR', receipt: '<order_rcptid_11>', order = Razorpay::Order.create
Copyvar options = { amount: 50000, // amount in the smallest currency unit currency: "INR", receipt: "order_rcptid_11" }; instance.orders.create(options, function(err, order) { console.log(order); });
Copy{ "id": "order_DBJOWzybf0sJbb", "entity": "order", "amount": 50000, "amount_paid": 0, "amount_due": 50000, "currency": "INR", "receipt": "rcptid_11", "status": "created", "attempts": 0, "notes": [], "created_at": 1566986570 }

Successful creation of the Order returns an id (referred to as order_id) that should be stored against the Order defined in your system.

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. See the list of supported currencies. Default is INR.
receipt optional
string Your receipt id for this order should be passed here. Maximum length 40 characters.
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 7: Add Razorpay Checkout Options to app.js File#

To integrate the Razorpay Checkout with your React Native app, you must add the Checkout Display Options in the app.js file.

Open the app.js file in your project folder and perform the following:

  1. Import the RazorpayCheckout module to your component.
Copyimport RazorpayCheckout from 'react-native-razorpay';
  1. Call the RazorpayCheckout.open method with the payment options. The method returns a JS Promise where the then part corresponds to a successful payment and the catch part corresponds to payment failure.
Copy<TouchableHighlight onPress={() => { var options = { description: 'Credits towards consultation', image: 'https://i.imgur.com/3g7nmJC.png', currency: 'INR', key: '<YOUR_KEY_ID>', amount: '5000', name: 'Acme Corp', order_id: 'order_DslnoIgkIDL8Zt',//Replace this with an order_id created using Orders API. Learn more at https://razorpay.com/docs/api/orders. prefill: { email: 'gaurav.kumar@example.com', contact: '9191919191', name: 'Gaurav Kumar' }, theme: {color: '#53a20e'} } RazorpayCheckout.open(options).then((data) => { // handle success alert(`Success: ${data.razorpay_payment_id}`); }).catch((error) => { // handle failure alert(`Error: ${error.code} | ${error.description}`); }); }}>

A descriptive list of valid options for checkout is available.

Step 8: Store Fields in Server#

A successful payment returns the following fields to the Checkout Form. Make provisions to store these fields on your server. You can confirm the authenticity of these details by verifying the signature in the next step.

Copy{ "razorpay_payment_id": "pay_29QQoUBi66xm2f", "razorpay_order_id": "order_9A33XWu170gUtm", "razorpay_signature": "9ef4dffbfd84f1318f6739a3ce19f9d85851857ae648f114332d8401e0949a3d" }
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 9: Verify Payment Signature#

This is a mandatory step that allows you 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 Dashboard.
  2. Use the SHA256 algorithm, the razorpay_payment_id and the order_id to construct a HMAC hex digest as shown below:

    Copygenerated_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#

Copy/** * This class defines common routines for generating * authentication signatures for Razorpay Webhook requests. */ public class Signature { private static final String HMAC_SHA256_ALGORITHM = "HmacSHA256"; /** * Computes RFC 2104-compliant HMAC signature. * * @param data * The data to be signed. * @param key * The signing key. * @return * The Base64-encoded RFC 2104-compliant HMAC signature. * @throws * java.security.SignatureException when signature generation fails */ public static String calculateRFC2104HMAC(String data, String secret) throws java.security.SignatureException { String result; try { // get an hmac_sha256 key from the raw secret bytes SecretKeySpec signingKey = new SecretKeySpec(secret.getBytes(), HMAC_SHA256_ALGORITHM); // get an hmac_sha256 Mac instance and initialize with the signing key Mac mac = Mac.getInstance(HMAC_SHA256_ALGORITHM); mac.init(signingKey); // compute the hmac on input data bytes byte[] rawHmac = mac.doFinal(data.getBytes()); // base64-encode the hmac result = DatatypeConverter.printHexBinary(rawHmac).toLowerCase(); } catch (Exception e) { throw new SignatureException("Failed to generate HMAC : " + e.getMessage()); } return result; } }
Copyuse Razorpay\Api\Api; $api = new Api($key_id, $key_secret); $attributes = array('razorpay_signature' => '23233', 'razorpay_payment_id' => '332' , 'order_id' => '12122'); $order = $api->utility->verifyPaymentSignature($attributes)
Copyrequire 'razorpay' Razorpay.setup('key_id', 'key_secret') payment_response = { 'order_id': '12122', 'razorpay_payment_id': '332', 'razorpay_signature': '23233' } Razorpay::Utility.verify_payment_signature(payment_response)
Copyimport razorpay client = razorpay.Client(auth = ('<key_id>', '<key_secret>')) params_dict = { 'order_id': '12122', 'razorpay_payment_id': '332', 'razorpay_signature': '23233' } client.utility.verify_payment_signature(params_dict)

Post Signature Verification#

After verifying the signature, fetch the order in your system that corresponds to the razorpay_order_id in your database. Mark it as successful and process the order.

Test the Integration#

Now that the integration is complete, you must ensure that your integration works as expected. You can make a test transaction using the test cards, verify the payment status from Dashboard, APIs or subscribe to related Webhook events to take appropriate actions at your end. After testing the integration in test mode, you can start accepting payments from your customers in real-time.

Test Payments#

You can make test payments using any of the payment methods configured on the Checkout. No money is deducted from the customer's account as this is a simulated transaction. In the Checkout code, ensure that you have entered the API keys generated in the test mode.

Test Cards#

You can use any of the test cards to make transactions in the test mode. Use any valid expiration date in the future and any random CVV to create a successful payment.

Verify the Payment Status#

You can track the status of the payment from the Dashboard or subscribe to the Webhook event or poll our APIs.

From the Dashboard#

  1. Log into your Dashboard and navigate to TransactionsPayments.
  2. Look if a payment_ID has been generated. If no payment_ID has been generated, it means that the transaction has failed.

Subscribe to Webhook events#

You can subscribe to a Webhook event that is generated when a certain event happens in our server. When one of those events is triggered, Razorpay sends the Webhook payload to the configured URL.

Learn how to set up Webhooks.

When the customer makes a successful payment on the Checkout, payment.authorized event is created in Razorpay.

Poll APIs#

You can retrieve the status of the payments by polling our Payment APIs.

Accept Live Payments#

After testing the flow of funds end-to-end in test mode, you are now ready to take your integration live. Once you are confident that the integration is working fine, you can switch to the live mode and start accepting payments from customers. But first, you need to swap the test API keys with the live keys.

To generate API key in live mode:

  1. Log into Dashboard and switch to Live mode on the menu.
  2. Navigate to SettingsAPI KeysGenerate Key to generate API key for live mode.
  3. Download the keys and save it securely.
  4. Replace the test API key with the Live Key in the Checkout code and start accepting real-time payments.
