1. Build Integration

Steps to integrate your Android application with Razorpay Android Standard SDK.


Follow these steps to integrate your Android application with Razorpay Android Standard SDK:

1.1 Install Razorpay Android Standard SDK.

1.2 Initialize Razorpay Android Standard SDK.

1.3 Create an Order in Server.

1.4 Initiate Payment and Display Checkout Form.

1.5 Handle Success and Error Events.

1.6 Store Fields in Server.

1.7 Verify Payment Signature.

1.8 Verify Payment Status.

1.1 Install Razorpay Android Standard SDK🔗

To install the SDK in your Android project:

Add the code given below to your project's top-level build.gradle file:
This gives access to the SDK library.

Copyrepositories { mavenCentral() } dependencies { implementation 'com.razorpay:checkout:1.6.24' }

1.2 Initialize Razorpay Android Standard SDK🔗

Add your Razorpay <API_KEY_ID> dynamically using Checkout's setKeyId() method. You can generate the API Keys from the Dashboard.

Copypublic class SomeEarlierMerchantActivity extends Activity { // ... @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); checkout.setKeyID("<YOUR_KEY_ID>"); // ... } }

Watch Out!
It is recommended to send the API Key ID from your server-side as app related metadata fetch.

Proguard Rules🔗

If you are using Proguard for your builds, you need to add the following lines to your proguard-rules.pro file.

Copy-keepclassmembers class * { @android.webkit.JavascriptInterface <methods>; } -keepattributes JavascriptInterface -keepattributes *Annotation* -dontwarn com.razorpay.** -keep class com.razorpay.** {*;} -optimizations !method/inlining/* -keepclasseswithmembers class * { public void onPayment*(...); }

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.

API Sample Code🔗

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

Copycurl -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 }'
CopyRazorpayClient razorpay = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]"); 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()); }
Copyimport razorpay client = razorpay.Client(auth=("YOUR_ID", "YOUR_SECRET")) DATA = { "amount": 100, "currency": "INR", "receipt": "receipt#1", "notes": { "key1": "value3", "key2": "value2" } } client.order.create(data=DATA)
Copy$api = new Api($key_id, $secret); $api->order->create(array('receipt' => '123', 'amount' => 100, 'currency' => 'INR', 'notes'=> array('key1'=> 'value3','key2'=> 'value2')));
CopyRazorpayClient client = new RazorpayClient(your_key_id, your_secret); Dictionary<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);
Copyrequire "razorpay" Razorpay.setup('YOUR_KEY_ID', 'YOUR_SECRET') options = amount: 50000, currency: 'INR', receipt: '<order_rcptid_11>' order = Razorpay::Order.create
Copyvar instance = new Razorpay({ key_id: 'YOUR_KEY_ID', key_secret: 'YOUR_SECRET' }) instance.orders.create({ amount: 50000, currency: "INR", receipt: "receipt#1", notes: { key1: "value3", key2: "value2" } })
Copyimport ( razorpay "github.com/razorpay/razorpay-go" ) client := razorpay.NewClient("YOUR_KEY_ID", "YOUR_SECRET") data := map[string]interface{}{ "amount": 50000, "currency": "INR", "receipt": "some_receipt_id" } body, err := client.Order.Create(data)
Copy{ "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 }

Request Parameters🔗

Here is the list of parameters for creating an order:

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. Length must be of 3 characters.
receipt optional
string Your receipt id for this order should be passed here. Maximum length 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 ₹7,000 is to be received from the customer in two installments of #1 - ₹5,000, #2 - ₹2,000, then you can set this value as 500000. This parameter should be passed only if partial_payment is true.

Know more about Orders API.

Error Response Parameters🔗

The error response parameters are available in the API Reference Guide.

1.4 Initiate Payment and Display Checkout Form🔗

SDK Integration Check🔗

Call Checkout.sdkCheckIntegration(activity) to check the health of integration. This will also let you know if the SDK version is outdated. This will only appear in debug mode and not in the release.

Preload Checkout🔗

To quickly load the Checkout form, the preload method of Checkout must be called much earlier than the other methods in the payment flow. The loading time of the preload resources can vary depending on your network's bandwidth.

Copypublic class SomeEarlierMerchantActivity extends Activity { // ... @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); /** * Preload payment resources */ Checkout.preload(getApplicationContext()); // ... } // ... }
Copyclass PaymentActivity: Activity(), PaymentResultListener { val TAG:String = PaymentActivity::class.toString() override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_payment) /* * To ensure faster loading of the Checkout form, * call this method as early as possible in your checkout flow * */ Checkout.preload(applicationContext) var button: Button = findViewById(R.id.btn_pay) button.setOnClickListener { startPayment() } }

Initiate a Payment🔗

There are two ways to pass the checkout parameters. You can either use payloadhelper or the JSONObject options. We recommend using payloadhelper as it ensures that the right data types are used for the parameter values.

PayloadHelper🔗

Create a JSONObject to send it to the SDK.

CopyPayloadHelper payloadHelper = new PayloadHelper("INR", 100, "order_"); payloadHelper.setName("Gaurav Kumar"); payloadHelper.setDescription("Test Payload Helper"); payloadHelper.setColor("#000000"); payloadHelper.setRetryEnabled(true); payloadHelper.setRetryMaxCount(1); payloadHelper.setSendSmsHash(true); payloadHelper.setPrefillName("Gaurav Kumar"); payloadHelper.setPrefillContact("9999999999"); payloadHelper.setPrefillEmail("gaurav.kumar@example.com"); JSONObject options = payloadHelper.getJson();
Copyval payloadHelper = PayloadHelper("INR", 100, "order_") payloadHelper.name = "Gaurav Kumar" payloadHelper.description = "Test Payload Helper" payloadHelper.color = "#000000" payloadHelper.retryEnabled = true payloadHelper.retryMaxCount = 1 payloadHelper.sendSmsHash = true payloadHelper.prefillEmail = "gaurav.kumar@example.com" payloadHelper.prefillContact = "9999999999" val options = payloadHelper.getJson()

If you want to create certain options that are not available, add them to the JSONObject we get from payloadHelper.getJson().

You can alternatively use the JSONObject options given below.

Create an instance of the Checkout and pass the payment details and options as a JSONObject. Ensure that you add the order_id generated in Step 3.

Copypublic void startPayment() { checkout.setKeyID("<YOUR_KEY_ID>"); /** * Instantiate Checkout */ Checkout checkout = new Checkout(); /** * Set your logo here */ checkout.setImage(R.drawable.logo); /** * Reference to current activity */ final Activity activity = this; /** * Pass your payment options to the Razorpay Checkout as a JSONObject */ try { JSONObject options = new JSONObject(); options.put("name", "Merchant Name"); options.put("description", "Reference No. #123456"); options.put("image", "https://s3.amazonaws.com/rzp-mobile/images/rzp.jpg"); options.put("order_id", "order_DBJOWzybf0sJbb");//from response of step 3. options.put("theme.color", "#3399cc"); options.put("currency", "INR"); options.put("amount", "50000");//pass amount in currency subunits options.put("prefill.email", "gaurav.kumar@example.com"); options.put("prefill.contact","9988776655"); JSONObject retryObj = new JSONObject(); retryObj.put("enabled", true); retryObj.put("max_count", 4); options.put("retry", retryObj); checkout.open(activity, options); } catch(Exception e) { Log.e(TAG, "Error in starting Razorpay Checkout", e); } }
Copyprivate fun startPayment() { /* * You need to pass current activity in order to let Razorpay create CheckoutActivity * */ val activity:Activity = this val co = Checkout() try { val options = JSONObject() options.put("name","Razorpay Corp") options.put("description","Demoing Charges") //You can omit the image option to fetch the image from dashboard options.put("image","https://s3.amazonaws.com/rzp-mobile/images/rzp.jpg") options.put("theme.color", "#3399cc"); options.put("currency","INR"); options.put("order_id", "order_DBJOWzybf0sJbb"); options.put("amount","50000")//pass amount in currency subunits val retryObj = new JSONObject(); retryObj.put("enabled", true); retryObj.put("max_count", 4); options.put("retry", retryObj); val prefill = JSONObject() prefill.put("email","gaurav.kumar@example.com") prefill.put("contact","9876543210") options.put("prefill",prefill) co.open(activity,options) }catch (e: Exception){ Toast.makeText(activity,"Error in payment: "+ e.message,Toast.LENGTH_LONG).show() e.printStackTrace() } }

Handy Tips
When you paste the checkout options given above, the following error message appears:
'TAG has private access in androidx.fragment.app.FragmentActivity'


You can resolve this by adding the following code:

Copypublic class MainActivity extends AppCompatActivity implements PaymentResultListener { private static final String TAG = MainActivity.class.getSimpleName();

Checkout.open() launches the Checkout form where the customer completes the payment and returns the payment result via appropriate callbacks on the PaymentResultListener.

Payment Options in JSONObject: All available options in the Standard Web Checkout are also available in Android.

Handy Tips
If you call the payment start method from inside a fragment, ensure that the fragment's parent activity implements the PaymentResultListener interface.

1.5 Handle Success and Error Events🔗

You have the option to implement PaymentResultListener or PaymentResultWithDataListener to receive callbacks for the payment result.

  • PaymentResultListener provides only payment_id as the payment result.
  • PaymentResultWithDataListener provides additional payment data such as email and contact of the customer, along with the order_id, payment_id, signature and more.

Sample Code🔗

Use the code given below to import the function in your .java file. This should be added at the beginning of the file.

Copyimport com.razorpay.PaymentResultListener
Copyimport com.razorpay.PaymentResultWithDataListener;

Sample Code🔗

Given below are the sample codes for implementation:

Copypublic class MerchantActivity extends Activity implements PaymentResultListener { // ... @Override public void onPaymentSuccess(String razorpayPaymentID) { /** * Add your logic here for a successful payment response */ } @Override public void onPaymentError(int code, String response) { /** * Add your logic here for a failed payment response */ } }
Copyclass PaymentActivity: Activity(), PaymentResultListener { // ... override fun onPaymentError(errorCode: Int, response: String?) { /** * Add your logic here for a failed payment response */ } override fun onPaymentSuccess(razorpayPaymentId: String?) { /** * Add your logic here for a successful payment response */ }
Copypublic class MerchantActivity extends Activity implements PaymentResultWithDataListener { // ... @Override public void onPaymentSuccess(String razorpayPaymentID, PaymentData paymentData) { /** * Add your logic here for a successful payment response */ } @Override public void onPaymentError(int code, String response) { /** * Add your logic here for a failed payment response */ } }
Copyclass PaymentActivity: Activity(), PaymentResultWithDataListener { // ... override fun onPaymentError(errorCode: Int, response: String?) { /** * Add your logic here for a failed payment response */ } override fun onPaymentSuccess(razorpayPaymentId: String?, PaymentData: PaymentData) { /** * Add your logic here for a successful payment response */ }

Watch Out!

  • Razorpay's payment process takes place in a new activity. Since there are two activities involved, your activity can get corrupted or destroyed if the device is low on memory. These two methods should not depend on any variables not set through your life cycle hooks.
  • It is recommended that you test everything by enabling "Don't Keep Activities" in Developer Options under Settings.

Error Codes🔗

The error codes that are returned in the onPaymentError method:

Error_Code

Description

Checkout.NETWORK_ERROR

There was a network error. For example, loss of internet connectivity.

Checkout.INVALID_OPTIONS

An issue with options passed in checkout.open.

Checkout.PAYMENT_CANCELED

User cancelled the payment.

Checkout.TLS_ERROR

The device does not support TLS v1.1 or TLS v1.2.

Erase User Data from SDK🔗

The SDK stores customer-specific data such as email, contact number, and user-session cookies if the customer wants to make another payment in the same session. You can delete such sensitive information before another customer logs into the app.

To erase customer data from the app, you can call the following method anywhere in your app.

CopyCheckout.clearUserData(Context)

Handy Tips
Contact our Support Team if you have any queries.

1.6 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.

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.

1.7 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:

    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🔗

Given below are the sample codes for payment signature verification.

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' , 'razorpay_order_id' => '12122'); $order = $api->utility->verifyPaymentSignature($attributes)
Copyrequire 'razorpay' Razorpay.setup('key_id', 'key_secret') payment_response = { 'razorpay_order_id': '12122', 'razorpay_payment_id': '332', 'razorpay_signature': '23233' } Razorpay::Utility.verify_payment_signature(payment_response)
Copyimport razorpay client = razorpay.Client(auth=("YOUR_ID", "YOUR_SECRET")) client.utility.verify_payment_signature({ 'razorpay_order_id': razorpay_order_id, 'razorpay_payment_id': razorpay_payment_id, 'razorpay_signature': razorpay_signature })
Copy Dictionary<string, string> attributes = new Dictionary<string, string>(); attributes.Add("razorpay_payment_id", paymentId); attributes.Add("razorpay_order_id", Request.Form["razorpay_order_id"]); attributes.Add("razorpay_signature", Request.Form["razorpay_signature"]); Utils.verifyPaymentSignature(attributes);
Copyvar { validatePaymentVerification } = require('./dist/utils/razorpay-utils'); validatePaymentVerification({"order_id": razorpayOrderId, "payment_id": razorpayPaymentId }, signature, secret);
Copyimport ( "crypto/hmac" "crypto/sha256" "crypto/subtle" "encoding/hex" "fmt" ) func main() { signature := "477d1cdb3f8122a7b0963704b9bcbf294f65a03841a5f1d7a4f3ed8cd1810f9b" secret := "qp3zKxwLZxbMORJgEVWi3Gou" data := "order_J2AeF1ZpvfqRGH|pay_J2AfAxNHgqqBiI" //fmt.Printf("Secret: %s Data: %s\n", secret, data) // Create a new HMAC by defining the hash type and the key (as byte array) h := hmac.New(sha256.New, []byte(secret)) // Write Data to it _, err := h.Write([]byte(data)) if err != nil { panic(err) } // Get result and encode as hexadecimal string sha := hex.EncodeToString(h.Sum(nil)) fmt.Printf("Result: %s\n", sha) if subtle.ConstantTimeCompare([]byte(sha), []byte(signature)) == 1 { fmt.Println("Works") } }

Post Signature Verification🔗

After you have successfully completed the integration, you can set up webhooks, make test payments, replace test key with live key and integrate with other APIs.

1.8 Verify Payment Status🔗

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

Verify Payment Status From Dashboard🔗

  1. Log into 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 Razorpay 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 set up Webhooks.

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.

Poll APIs🔗

Poll Payment APIs to check the payment status.
