The Cashfree Android SDK allows you to integrate Cashfree Payment Gateway into your application and start collecting payments from your customers. It is designed to minimise the complexity of handling and integrating payments in your application.

The Cashfree Android SDK Integration sample is available at the Github repo.

Watch the video to know how to integrate Cashfree Android SDK with your Android application:

Integration Steps

To integrate Cashfree Android SDK with your Android application,

1. Create an account with Cashfree and get the API keys
2. Integrate the Cashfree SDK into your application
3. Generate Token - From Backend
4. Initiate payment - Invoke a payment API from the Cashfree SDK with the token generated when the customer initiates payment for an order from your application. Cashfree SDK displays appropriate screens to the customer for the payment.
5. Receive and handle response - Cashfree SDK returns the payment result for the order which should be handled in your application.
6. Verify response - It is mandatory to verify the payment response by checking the signature value returned in the payment response. It is also highly recommended to implement webhook notifications to receive a notification from the Cashfree backend to your backend whenever a payment is successful for an order.

Step 1: Create Account and Get API Keys

1. Go to Cashfree website and create an account. Click here for detailed steps on how to create and activate your account.
2. Log in to your Merchant Dashboard using the same credentials.
3. Click Payment Gateway section View Dashboard click Credentials. For security purposes, you need to enter your password for verification.
4. Copy the app ID and the secret key. These values are required to create the order token from your server. Order tokens are used to authenticate the API calls made from Cashfree Android SDK.

Step 2: Integrate SDK

The Cashfree SDK is bundled as an AAR file according to the latest Android standards. We support integration from API level 16. Ensure that the minSdkVersion in the build.gradle of your app is equal to or greater than that.

To integrate the SDK, follow the steps below:

Step 2.1: Add Cashfree maven repository to your module's build.gradle file.
Gradle Script

repositories 
{
    maven 
    { 
      url 'https://maven.cashfree.com/release'
    }
}

Step 2.2: Gradle Changes
Step 2.2.1 Open the build.gradle file of your module and add the Cashfree SDK in the dependency section.

For the android support library version, add the following:

implementation 'com.cashfree.pg:android-support-sdk:1.4.2.2'

For the latest androidX library version, add the following:

implementation 'com.cashfree.pg:android-sdk:1.7.28' 

Step 2.2.2 Add other dependencies
You need to add a few additional dependencies to the build.gradle file depending on the payment type.

Click the links below to know more about what dependencies need to be added:

• Checkout
• Google Pay
• Amazon Pay
• PhonePe
• UPI Intent

Step 2.3: Android Manifest Changes
The Cashfree SDK requires you to add the permissions shown below in your Android Manifest file.

<manifest ...>
  <uses-permission android:name="android.permission.INTERNET" />
  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application ...>

📘

Add android.useAndroidX=true in gradle.properties file.

• Set the tools:node attribute to "merge" in the definition of your application element in the Android Manifest file.
• If the OTP auto-read-submit feature is enabled for your account add the Google Play services version meta-data.

<application
    ...
    tools:node="merge">
    <!--Only add it if you need Auto OTP reading feature is enabled-->
    <meta-data android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />
 </application>

Step 3: Generate Token (From Backend)

The cftoken is used to authenticate the payment requests made from SDK. It has to be generated for every payment attempt made for an order. Pass this token to the SDK while initiating the payment for that order. For generating a cftoken you need to use our token generation API.

Request Description to Generate Token
Production - set the URL to https://api.cashfree.com/api/v2/cftoken/order
Testing - set the action URL to https://test.cashfree.com/api/v2/cftoken/order

You need to send orderId, orderCurrency and orderAmount as a JSON object to the API endpoint and in response, you will receive a token. Please see the description of the request below.

curl -XPOST -H 'Content-Type: application/json'
-H 'x-client-id: <YOUR_APP_ID>'
-H 'x-client-secret: <YOUR_SECRET_KEY>'
-d '{
  "orderId": "<ORDER_ID>",
  "orderAmount":<ORDER_AMOUNT>,
  "orderCurrency": "INR"
}' 'https://test.cashfree.com/api/v2/cftoken/order'

Request Example: Replace YOUR_APP_ID and YOUR_SECRET_KEY with actual values.

curl -XPOST -H 'Content-Type: application/json' -H 'x-client-id: YOUR_APP_ID' -H 'x-client-secret: YOUR_SECRET_KEY' -d '{
  "orderId": "Order0001",
  "orderAmount":1,
  "orderCurrency":"INR"
}' 'https://test.cashfree.com/api/v2/cftoken/order'

Response Example

{
  "status": "OK",
  "message": "Token generated",
  "cftoken": "v79JCN4MzUIJiOicGbhJCLiQ1VKJiOiAXe0Jye.s79BTM0AjNwUDN1EjOiAHelJCLiIlTJJiOik3YuVmcyV3QyVGZy9mIsEjOiQnb19WbBJXZkJ3biwiIxADMwIXZkJ3TiojIklkclRmcvJye.K3NKICVS5DcEzXm2VQUO_ZagtWMIKKXzYOqPZ4x0r2P_N3-PRu2mowm-8UXoyqAgsG"
}

This API should be called from your server (backend) only, and never from your Android application as it uses the secretKey.

Step 4: Initiate Payment

After generating the order token, the payment gets initiated when the payment APIs are called (doPayment, doUPIPayment, doGPayPayment, doAmazonPayment).

For payment, your application passes the order info and the cftoken to the SDK. The relevant payment screen is displayed to the customer where they enter the required information and make the payment. After the payment is complete the customers are redirected to the Android application and a response is received on onActivityResult().

📘

• The order details passed during the token generation and the payment initiation should match. Else, you will get an Invalid order details error.
• Wrong appId and token will result in Unable to authenticate merchant error. The token generated for payment is valid for 5 minutes within which the payment has to be initiated. Else, you will get an Invalid token error.

Step 5. Receive and Handle Response

After the payment is complete you will receive the response on the onActivityResult() function of the invoking activity. In the intent extras, you will receive a set of response parameters which is used to determine if the transaction was successful or not. Request code will always be equal to CFPaymentService.REQ_CODE.

@Override
protected  void  onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        //Same request code for all payment APIs.
        Log.d(TAG, "ReqCode : " + CFPaymentService.REQ_CODE);
        Log.d(TAG, "API Response : ");
        //Prints all extras. Replace with app logic.
        if (data != null) {
            Bundle  bundle = data.getExtras();
            if (bundle != null)
                for (String  key  :  bundle.keySet()) {
                    if (bundle.getString(key) != null) {
                        Log.d(TAG, key + " : " + bundle.getString(key));
                    }
                }
        }
}

Step 6. Verify Response

Once the SDK returns a response to the application, it is mandatory to verify the payment response by verifying the signature value returned in the payment response. It is also highly recommended to implement webhook notification to receive a notification from Cashfree backend to your backend whenever a payment is successful for an order.

Click here to know about the implementation details.

Sample Application

Click here to view the sample application.

Checkout

Checkout is the standard flow for Cashfree Android SDK. In this flow, SDK loads a webview which renders Cashfree's payment page. Customers can fill in the details here and complete the payment.
There are two types of Web Checkout methods. You can select the required method based on your business need.

• Normal - Customer selects the payment mode and enters the payment details within Cashfree's web payment page to complete the payment.
• Seamless - Customer selects the payment mode and enters payment details in your application. These details are then passed on to the Cashfree SDK. Webview is launched only for two-factor authentication.
• Web checkout includes Google pay, Amazon pay, PhonePe and UPI payment modes.
• The difference between web checkout and the other payment APIs (doGPayPayment() etc) is that the web checkout initiates a collect request instead of opening the applications directly for payment.
• In a collect request, after the payment for an order is initialised, a notification is received in that respective application and the user proceeds with the payment.

doPayment

The doPayment method initiates the payment inside a webview. The customer will be taken to the payment page where they can pay through any of the payment methods that is activated for their account. Once the payment is complete the webview will close and the response will be delivered through onActivityResult().

public void doPayment(Context context, Map<String, String> params, String token, String stage)

Parameters:

• context: Context of the calling activity.
• params: A map of all the relevant parameters described here.
• token: The token generated here.
• stage: Value should be either "TEST" for testing server, or "PROD" for production server respectively.

public void doPayment(Context context, Map<String, String> params, String token, String stage, String color1, String color2)

Additional Parameters:

• color1: Toolbar background color.
• color2: Toolbar text and back arrow color.

If you want to hide the order ID, add another parameter hideOrderID as shown below:

public void doPayment(Context context, Map<String, String> params, 
String token, String stage, boolean hideOrderId)

If you want to customise the toolbar colour and also hide the order ID in the toolbar, add the parameters as shown below:

public void doPayment(Context context, Map<String, String> params, 
String token, String stage, String color1, String color2, 
boolean hideOrderId)

Seamless Integration

When you have a requirement for a customised payment flow, you can use seamless integration. You can implement the payment page as per your requirement and then use our SDK to authorise the payment. Once the payment details are collected the OTP or the two-factor authentication page will open in a webview. After the payment is confirmed the webview closes and you will receive a response.

We recommend that you use the Checkout integration method unless you are certain that you require a customised payment flow.

The following sections describe the additional parameters for each of the payment methods:

Credit/Debit Card

Add the following parameters to the params map before invoking the doPayment() method to initiate a seamless card transaction.

params.put(PARAM_PAYMENT_OPTION, "card");
params.put(PARAM_CARD_NUMBER, "4434260000000008");//Replace Card number
params.put(PARAM_CARD_MM, "05"); // Card Expiry Month in MM
params.put(PARAM_CARD_YYYY, "2021"); // Card Expiry Year in YYYY
params.put(PARAM_CARD_HOLDER, "John Doe"); // Card Holder name
params.put(PARAM_CARD_CVV, "123"); // Card CVV

Net Banking

Add the following parameters to the params map before invoking doPayment() method to initiate a seamless net banking transaction. All valid bank codes are available here.

params.put(PARAM_PAYMENT_OPTION, "nb");
params.put(PARAM_BANK_CODE, "3333");// Put correct bank code here

Wallet

Add the following parameters to the params map before invoking doPayment() method to initiate a seamless wallet transaction. All valid wallet codes are available here.

params.put(PARAM_PAYMENT_OPTION, "wallet");
params.put(PARAM_WALLET_CODE, "4001");// Put correct wallet code here

UPI

Add the following parameters to the params map before invoking doPayment() method to initiate a seamless UPI transaction.

params.put(PARAM_PAYMENT_OPTION, "upi");
params.put(PARAM_UPI_VPA, "testsuccess@gocash");// Put correct upi vpa here

Paypal

Add the following parameters to params map before invoking doPayment() method to initiate a seamless Paypal transaction.

params.put(PARAM_PAYMENT_OPTION, "paypal");

Third-Party Validation

The Android SDK also supports Third Party Validation through Seamless Web Checkout.

There is no change in the integration method, the only exception is that you have to send us the pre-registered account number and IFSC code for each of your customers as part of the request parameter.

For TEST credentials and more information about parameters to be sent, visit here

UPI Intent

When the doUPIPayment method is invoked the customer is shown a list of all the installed UPI applications on their phone. After the customer selects their preferred application, the payment confirmation page will open in the application. After payment completion, the response is delivered through onActivityResult().

You also have the option to display the UPI applications in your user interface and send the response to Cashfree to launch the application selected by the customer.

Note: Payments on Test server will go via UPI simulator and will be considered as mock payments. Switch to Production server to do live payments.

Android Manifest Change

If the project's targetSdkVersion is 30, add the following code to the android manifest file.

<manifest package="com.example.game">
<queries>
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="upi" android:host="pay"/>
    </intent>
    <package android:name="com.android.chrome" />
</queries>
    ...
</manifest>

Initiate Payment

public  void  upiPayment(Context context, Map<String, String> params, String token, String stage)

Parameters:

• context: Context object of the calling activity is required for this method. In most cases, this will mean sending the instance of the calling activity (this).
• params: A map of all the relevant parameters described here.
• token: The token generated here
• stage: Value should be either "TEST" or "PROD" for testing server or production server respectively.

Select Upi Client

When initiating the UPI intent the customer is shown a list of all the UPI client applications (BHIM, GPay, PhonePe etc.) on their phone. This allows the customer to select any UPI application they want to pay with. If you want the customer to pay with a particular app you can use the parameter upiClientPackage. After calling this method whenever upiPayment is called the customer will not see the application selection screen, instead will be redirected to the application whose package is provided in the parameters.

public void selectUpiClient(String upiClientPackage)

Parameters:

• upiClientPackage: The string describing the java package of the upi client that is to be selected.

Get UPI Clients

Get the packages of all the UPI Clients installed on the device as a string array. These packages can then be passed to selectUpiClient() method to initiate the payment.

public String[] getUpiClients(Context context)

Get the packages of all the UPI Clients installed on the device as a string array. These packages can then be passed to selectUpiClient() method to initiate payment.

Parameters

• context: Context object of the calling activity is required for this method.

📘

Create a new order ID every time you invoke the UPI payment flow since UPI intent flow can be initiated once per order ID.

Seamless UPI

When you want to show your own customised payment screen with specific UPI payment applications, you can use our seamless UPI integration method. Here customers click on the required application and make the payment. You can implement the payment page as per your requirement and then use our SDK to authorise the payment.

The following section describes the additional parameters required for UPI seamless integration.

... // required params
params.put("appName", "-upi app 'id' here-"); // upi app id the user selected from function

You get the appName value from the id parameter specified in the getUpiClients function.

Direct App Integration

Google Pay

The doGPayPayment API opens the Google Pay application directly for the customer to make the payment. On payment completion, the SDK verifies the payment and the response is delivered through onActivityResult().

Add Dependencies

Add the google maven repository to your project in the top-level build.gradle. Add the following google maven repository to your project at the top level (project) build.gradle only if you are using doGPayPayment() function.

allprojects{
  repositories {
    google()
    ...
  }
}

Add the following dependencies to your module.

dependencies {
    ...
    //Dependencies used by all payment functions
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'com.android.volley:volley:1.1.1'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

    //doGPayPayment  - Also add the google maven repository as shown in the consecutive step
    implementation 'com.cashfree.pg:gpay-sdk:1.0.0'
    implementation 'com.google.android.gms:play-services-tasks:15.0.1'

}

Check if Google Pay is Ready

You need to first check if the Google Pay app is available for payments.
Call the function isGPayReadyForPayment before showing the GPay payment option to the user. It checks if the GPay app is installed in the device and if it is ready for making payments.

public  void  isGPayReadyForPayment(Context context, 
final  GooglePayStatusListener listener)

Parameters:

• context: Context of the calling activity.
• listener: GooglePayStatusListener to receive the result.

public  interface  GooglePayStatusListener {
    void  isReady();
    void  isNotReady();
}

Initiate Payment

public  void  gPayPayment(Context context, Map<String, String> params, String token, String stage)

Parameters:

• context: Context of the calling activity.
• params: A map of all the relevant parameters described here.
• token: The token generated here
• stage: The value should be "TEST" for testing server, or "PROD" for the production server respectively.

Amazon Pay

The doAmazonPayment API initiates the payment inside chrome custom tab (or default browser if it is not available) where the customer is shown the amazon pay payment page. After the payment is complete and the customer closes the chrome tab, the SDK verifies the payment. After the payment is verified, the user is redirected to the application. The response is delivered through onActivityResult().

Add Dependencies

dependencies {
    ...
    //Dependencies used by all payment functions
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'com.android.volley:volley:1.1.1'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    //doAmazonPayment
    implementation 'androidx.browser:browser:1.0.0'
}

Initiate Payment

public  void  doAmazonPayment(Context context, Map<String, String> 
params, String token, String stage)

Parameters:

• context: Context of the calling activity.
• params: A map of all the relevant parameters described here.
• token: The token generated here
• stage: The value should be "TEST" for testing server, or "PROD" for production server respectively.

PhonePe

After the payment is initiated, PhonePe app is opened directly for payment. After the payment is complete, the SDK verifies the payment. The response is delivered through onActivityResult().

📘

Transactions that happen through direct PhonePe integration mode are considered wallet transactions and not UPI transactions.

Add Dependencies

dependencies {
    ...
    //Dependencies used by all payment functions
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'com.android.volley:volley:1.1.1'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
}

Check if PhonePe is Ready

You need to first check if PhonePe App is available for payment.

Call the function doesPhonePeExist before showing PhonePe as a payment option to the user. It checks if the device has a valid version of PhonePe app installed. If it is available then it checks if the app is set up to make payments.

public  boolean  doesPhonePeExist(Context context, String stage)

Parameters:

• context: Context of the calling activity.
• stage: The value should be "TEST" for testing server, or "PROD" for production server respectively.

Initiate Payment

public  void  phonePePayment(Context context, Map<String, String> params, 
String token, String stage)

Parameters:

• context: Context of the calling activity.
• params: A map of all the relevant parameters described here.
• token: The token generated here
• stage: The value should be "TEST" for testing server, or "PROD" for the production server respectively.

Other Common SDK Functions

getUpiClients

This function fetches the list of UPI apps installed in the user device.

public void getUpiClients(Context context, IUPIAppsCallback callback);

Response

Returns a Callback in IUPIAppsCallback with a result as a List of Map containing upi apps installed in the user device or an exception if no UPI applications are found.

Response Parameters:

• displayName: Display name of the app to be used to show in the UI.
• id: UPI app id to be used in UPI seamless Flow (with key appName).
• icon: Icon of the UPI app encoded in Base64 to show in the UI.

Sample response parsed to JSON:

[
   {
      “displayName”: “Gpay”,
      “id”: “com.google.android.apps.nbu.paisa.user”,
      “icon”: “iVBORw0KGgoAAAANSUhEUgAAALQAAAC0CAYAAAA9zQYyAAAAAXNSR0IArs4c6QAA... (in base64)”
      },
   {
      “displayName”: “PHONEPE”,
      “id”: “com.phonepe.app”,
      “icon”: “iVBORw0KGgoAAAANSUhEUgAAALQAAAC0CAYAAAA9zQYyAAAAAXNSR0IArs4c6QAA... (in base64)”
   }
]

SetOrientation

Choose the orientation (portrait or landscape) of the payment page. By default the payment page is shown in portrait orientation.

public void setOrientation(Context context, int val)

Parameters:

• val: If the integer value is zero the orientation will be in portrait mode. Else, it will be landscape mode.
• context: Context of the calling activity.

SetConfirmOnExit

By default, a confirmation dialog is displayed when the users press back in the payment screen. You have the option to disable the confirmation dialog.

public void setConfirmOnExit(Context context, boolean confirmOnExit)

Parameters:

• context: Context of the calling activity.
• confirmOnExit: Value should be true if you want to show a confirmation popup on pressing back in the payment screen.

Verify Response

Once the SDK returns a response to the application, it is mandatory to verify the payment response by verifying the signature value returned in the payment response and it also highly recommended to implement webhook notification.

Webhook Notifications

Webhooks are events that notify you about the payment. We send a notification from Cashfree backend to your backend whenever a payment is successful for an order. The notification will be sent to notifyUrl which is specified during order creation.
To specify notifyUrl, add it with other parameters (orderId, orderAmount etc.) as shown below:

params.put(PARAM_NOTIFY_URL, "https://example.com/path/to/notify/url/")

📘

• Notifications are usually instant but in some rare cases it can take up to a minute to hit your server. Make sure that your URL supports https. Notifications are sent only in the case of successful payments.
• Sometimes you may receive the same notification two or more times. It is recommended to ensure that your implementation of the webhook is idempotent.
• Ensure that you verify the signature in the webhook response.
• This also handles scenarios for users in cases like the internet connection lost after payment, or user closing the application after payments, etc. It helps to reconcile all the successful orders at your end.

The parameters sent in notification are described here.

Verify Signature

Verify the signature value in the payment response to check the authenticity of the transaction response. In every response, we add a digital signature to establish the authenticity of the message. We require you to verify the signature received at your end to ensure that the response has not been tampered. This verification has to be done on your server as involves secretKey which should not be exposed on the client side.
