3.1 Initiate payment - Web checkout payment
Web Checkout flow
Web checkout flow is the another payment flow similar to Drop flow for collection payments using the Cashfree payment gateway's Android SDK. 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.
We have added this mode for giving access to some features which are only available in the web checkout flow now.
Initiating the payment
To initiate the Web checkout payment in the SDK, follow these steps
- Create a CFSession object.
- Create a CFTheme object.
- Create a Web Checkout Payment object.
- Set payment callback.
- Initiate the payment using the payment object created from [step 4]
Create a session
The payment_session_id
created from Step 2 is used to authenticate the payment. The SDK exposes a class CFSession
class which accepts the payment_session_id
, Environment
and order ID
values.
Cashfree provides two environments, one being the sandbox
environment for developers to test the payment flow and responses and the other being production
environment which gets shipped to production. This environment can be set in this session object.
The values for environment can be either .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()
Set a Theme
CFWebCheckoutTheme cfTheme = new CFWebCheckoutTheme.CFWebCheckoutThemeBuilder()
.setNavigationBarBackgroundColor("#6A3FD3")
.setNavigationBarTextColor("#FFFFFF")
.build();
val cfTheme = CFWebCheckoutThemeBuilder()
.setNavigationBarBackgroundColor("#000000")
.setNavigationBarTextColor("#FFFFFF")
.build()
The CFWebCheckoutThemeBuilder
class used to create CFWebCheckoutTheme
used to set the theming for Web checkout screen.
Create a Web Checkout Payment object
- Code Snippet to create a payment object for Web Checkout (pre-built Web UI SDK)
CFWebCheckoutPayment cfWebCheckoutPayment = new CFWebCheckoutPayment.CFWebCheckoutPaymentBuilder()
.setSession(cfSession)
.setCFWebCheckoutUITheme(cfTheme)
.build();
val cfWebCheckoutPayment = CFWebCheckoutPaymentBuilder()
.setSession(cfSession)
.setCFWebCheckoutUITheme(cfTheme)
.build()
If payment component object is not provided then all the payment modes that are enabled for the merchant account is shown.
Setup Payment Callback
The SDK exposes an interface CFCheckoutResponseCallback
to receive callbacks from the SDK once the payment flow ends.
This protocol comprises of 2 methods:
public void onPaymentVerify(String orderID)
public void onPaymentFailure(CFErrorResponse cfErrorResponse, String orderID)
- Code snippet demonstrating it's usage:
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_web_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 WebCheckoutActivity : 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)
}
...
}
Make sure to set the callback at activity's onCreate as this also handles the activity restart cases.

Verify Payment
As a best practise you should always verify the payment status from your backend. Refer here for details steps on how to verify payment.
