Android Integration

Cashfree’s Integrity Standards

Before proceeding with the SDK integration, please ensure that your application complies with Cashfree’s Integrity. Applications that don’t meet the required integrity standards may be restricted from using production services.For further guidance, refer to the Cashfree Integrity.

Setting Up SDK

implementation 'com.cashfree.pg:api:2.2.8'

Step 1: Creating an Order

The first step in the Cashfree Payment Gateway integration is to create an Order. You need to do this before any payment can be processed. You can add an endpoint to your server which creates this order and is used for communication with your frontend.

Order creation must happen from your backend (as this API uses your secret key). Please do not call this directly from your mobile application.

API Request for Creating an Order

Here’s a sample request for creating an order using your desired backend language. Cashfree offers backend SDKs to simplify the integration process. You can find the SDKs here.

import { Cashfree, CFEnvironment } from "cashfree-pg";

const cashfree = new Cashfree(
	CFEnvironment.PRODUCTION,
	"{Client ID}",
	"{Client Secret Key}"
);

function createOrder() {
	var request = {
		order_amount: "1",
		order_currency: "INR",
		customer_details: {
			customer_id: "node_sdk_test",
			customer_name: "",
			customer_email: "example@gmail.com",
			customer_phone: "9999999999",
		},
		order_meta: {
			return_url:
				"https://test.cashfree.com/pgappsdemos/return.php?order_id=order_123",
		},
		order_note: "",
	};

	cashfree
		.PGCreateOrder(request)
		.then((response) => {
			var a = response.data;
			console.log(a);
		})
		.catch((error) => {
			console.error("Error setting up order request:", error.response.data);
		});
}

After successfully creating an order, you will receive a unique order_id and payment_session_id that you need for subsequent steps. You can view all the complete api request and response for /orders here.

Step 2: Opening the Payment Page

Once the order is created, the next step is to open the payment page so the customer can make the payment. Cashfree Android SDK offer below payment flow.

Web Checkout

In this flow, SDK provides a webview based checkout implementation to facilitate a quick integration with our payment gateway. Your customers can fill in the necessary details in the web page and complete the payment. This mode also handles all the business logic and UI Components to make the payment smooth and easy to use.

UPI Intent Checkout

This flow is for merchants who wants to quickly provide UPI Intent functionality using cashfree’s mobile SDK. In this flow, SDK provides a pre-built native Android screen to facilitate a quick integration with our payment gateway. Your customers will see a list of UPI apps installed in their phone which they can select to initiate payment. This mode handles all the business logic and UI Components to make the payment smooth and easy to use. The SDK allows the merchant to customize the UI in terms of color coding, fonts.

To complete the payment, we can follow the following steps:

Create a CFSession object.
Create a CFTheme object.
Create a CFWebCheckoutPayment/CFUPIIntentCheckoutPayment object.
Set payment callback.
Initiate the payment using the payment object created from [step 3]

We go through these step by step below.

Create a Session

This object contains essential information about the order, including the payment session ID (payment_session_id) and order ID (order_id) obtained from Step 1. It also specifies the environment (sandbox or production).

CFSession cfSession = new CFSession.CFSessionBuilder()
        .setEnvironment(CFSession.Environment.SANDBOX)
        .setPaymentSessionID("paymentSessionID")
        .setOrderId("orderID")
        .build();

val cfSession = CFSessionBuilder()
    .setEnvironment(CFSession.Environment.SANDBOX)
    .setPaymentSessionID("paymentSessionID")
    .setOrderId("orderID")
    .build()

Customize Theme (Optional)

You can customize the appearance of the checkout screen using CFTheme. This step is optional but can help maintain consistency with your app’s design.

Web Checkout

CFWebCheckoutTheme cfTheme = new CFWebCheckoutTheme.CFWebCheckoutThemeBuilder()
    .setNavigationBarBackgroundColor("#6A3FD3")
    .setNavigationBarTextColor("#FFFFFF")
    .build();

val cfTheme = CFWebCheckoutThemeBuilder()
    .setNavigationBarBackgroundColor("#000000")
    .setNavigationBarTextColor("#FFFFFF")
    .build()

UPI Intent Checkout

CFIntentTheme cfTheme = new CFIntentTheme.CFIntentThemeBuilder()
    .setPrimaryTextColor("#000000")
    .setBackgroundColor("#FFFFFF")
    .build();

val cfTheme = CFIntentThemeBuilder()
    .setPrimaryTextColor("#000000")
    .setBackgroundColor("#FFFFFF")
    .build()

Create Checkout Payment Object

Web Checkout

This object combines all the configurations (session, theme) into a single checkout configuration. Finally, call doPayment() to open the Cashfree web checkout screen. This will present the user with the payment options and handle the payment process.

CFWebCheckoutPayment cfWebCheckoutPayment = new CFWebCheckoutPayment.CFWebCheckoutPaymentBuilder()
    .setSession(cfSession)
    .setCFWebCheckoutUITheme(cfTheme)
    .build();

val cfWebCheckoutPayment = CFWebCheckoutPaymentBuilder()
  .setSession(cfSession)
  .setCFWebCheckoutUITheme(cfTheme)
  .build()

UPI Intent Checkout

This flow is for merchants who wants to quickly provide UPI functionality using cashfree’s mobile SDK without handling other modes like Cards or Net banking.

CFUPIIntentCheckout cfupiIntentCheckout = new CFUPIIntentCheckout.CFUPIIntentBuilder()
        // Use either the enum or the application package names to order the UPI apps as per your needed
        // Remove both if you want to use the default order which cashfree provides based on the popularity
        // NOTE - only one is needed setOrder or setOrderUsingPackageName
        .setOrder(Arrays.asList(CFUPIIntentCheckout.CFUPIApps.BHIM, CFUPIIntentCheckout.CFUPIApps.PHONEPE))
        .setOrderUsingPackageName(Arrays.asList("com.dreamplug.androidapp", "in.org.npci.upiapp"))
        .build();

CFUPIIntentCheckoutPayment cfupiIntentCheckoutPayment = new CFUPIIntentCheckoutPayment.CFUPIIntentPaymentBuilder()
        .setSession(cfSession)
        .setCfUPIIntentCheckout(cfupiIntentCheckout)
        .setCfIntentTheme(cfTheme)
        .build();

val cfupiIntentCheckout = CFUPIIntentBuilder() // Use either the enum or the application package names to order the UPI apps as per your needed
        // Remove both if you want to use the default order which cashfree provides based on the popularity
        // NOTE - only one is needed setOrder or setOrderUsingPackageName
        .setOrderUsingPackageName(Arrays.asList("com.dreamplug.androidapp", "in.org.npci.upiapp"))
        .setOrder(Arrays.asList(CFUPIIntentCheckout.CFUPIApps.BHIM, CFUPIIntentCheckout.CFUPIApps.PHONEPE))
        .build()

val cfupiIntentCheckoutPayment = CFUPIIntentPaymentBuilder()
        .setSession(cfSession)
        .setCfUPIIntentCheckout(cfupiIntentCheckout)
        .setCfIntentTheme(cfTheme)
        .build()

Setup payment callback

The SDK exposes an interface CFCheckoutResponseCallback to receive callbacks from the SDK once the payment journey ends. This interface consists of 2 methods:

public void onPaymentVerify(String orderID)
public void onPaymentFailure(CFErrorResponse cfErrorResponse, String orderID)

fun onPaymentVerify(orderID: String)
fun onPaymentFailure(cfErrorResponse: CFErrorResponse, orderID: String) 

Make sure to set the callback at activity’s onCreate as this also handles the activity restart cases.

public class YourActivity extends AppCompatActivity implements CFCheckoutResponseCallback {
    ...
    @Override
    public void onPaymentVerify(String orderID) {

    }

    @Override
    public void onPaymentFailure(CFErrorResponse cfErrorResponse, String orderID) {

    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_upi_intent_checkout);
        try {
          // If you are using a fragment then you need to add this line inside onCreate() of your Fragment
            CFPaymentGatewayService.getInstance().setCheckoutCallback(this);
        } catch (CFException e) {
            e.printStackTrace();
        }
    }
    ...

}

class YourActivity : AppCompatActivity(), CFCheckoutResponseCallback {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_drop_checkout)
        try {
            CFPaymentGatewayService.getInstance().setCheckoutCallback(this)
        } catch (e: CFException) {
            e.printStackTrace()
        }
    }

    override fun onPaymentVerify(orderID: String) {
        Log.d("onPaymentVerify", "verifyPayment triggered")
    }

    override fun onPaymentFailure(cfErrorResponse: CFErrorResponse, orderID: String) {
        Log.e("onPaymentFailure $orderID", cfErrorResponse.message)
    }
...
}

Open Checkout Screen

Finally, call doPayment() to open the Cashfree checkout screen. This will present the user with the payment options and handle the payment process.

Web Checkout

// replace the WebCheckoutActivity class with your class name
CFPaymentGatewayService.getInstance().doPayment(WebCheckoutActivity.this, cfWebCheckoutPayment);

// replace the WebCheckoutActivity class with your class name
CFPaymentGatewayService.getInstance().doPayment(this@WebCheckoutActivity, cfWebCheckoutPayment)

UPI Intent Checkout

// replace the UPIIntentCheckoutActivity class with your class name
CFPaymentGatewayService.getInstance().doPayment(UPIIntentCheckoutActivity.this, cfupiIntentCheckoutPayment);

// replace the UPIIntentCheckoutActivity class with your class name
CFPaymentGatewayService.getInstance().doPayment(this@UPIIntentCheckoutActivity, cfupiIntentCheckoutPayment)

Step 4: Confirming the Payment

After the payment is completed, you need to confirm whether the payment was successful by checking the order status. Once the payment finishes, the user will be redirected back to your activity to your implementation of the CFCheckoutResponseCallback interface.

You must always verify payment status from your backend. Before delivering the goods or services, please ensure you call check the order status from your backend. Ensure you check the order status from your server endpoint.

To verify an order you can call our /pg/orders endpoint from your backend. You can also use our SDK to achieve the same.

version := "2023-08-01"
response, httpResponse, err := cashfree.PGFetchOrder(&version, "<order_id>", nil, nil, nil)
if err != nil {
	fmt.Println(err.Error())
} else {
	fmt.Println(httpResponse.StatusCode)
	fmt.Println(response)
}

cashfree
	.PGFetchOrder("<order_id>")
	.then((response) => {
		console.log("Order fetched successfully:", response.data);
	})
	.catch((error) => {
		console.error("Error:", error.response.data.message);
	});

$x_api_version = "2023-08-01";
try {
    $response = $cashfree->PGFetchOrder($x_api_version, "<order_id>");
    print_r($response);
