Create sessions to pay with a card and CVC

SDK v3
Last updated January 2024

Use our Android SDK to secure your customer's payment details by creating separate sessions for the card details and CVC.

Full sample integration: You can see an example of the session generationhere.

Set your views

When you create your checkout form, you must set the views that your customers use to enter their card details and set unique identifiers for each of them.

As part of our SDK, we provide a UI Component dedicated to capturing your customer's card details to minimize your exposure to PCI Data.

You must use this component if you want to qualify for the lowest level of PCI compliance (SAQ-A).

Here's an example of how you would set your view configurations.

Copied!
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="match_parent" >

    <!-- layout style attributes omitted -->
    <AccessCheckoutEditText android:id="@+id/pan" />

    <!-- layout style attributes omitted -->
    <AccessCheckoutEditText android:id="@+id/expiryDate" />

    <!-- layout style attributes omitted -->
    <AccessCheckoutEditText android:id="@+id/cvc" />

    <!-- layout style attributes omitted -->
    <Button android:id="@+id/submit_button" />

</LinearLayout>

Reference your views

You must now reference your view configurations. Use the same unique view identifiersas above.

Here's an example of how you would reference your view configurations.

        val cvcAccessCheckoutView: AccessCheckoutEditText = findViewById<AccessCheckoutEditText>(R.id.card_flow_text_cvc)
        val expiryDateAccessCheckoutView: AccessCheckoutEditText = findViewById<AccessCheckoutEditText>(R.id.card_flow_text_expiryDate)
        val submit: Button = findViewById<Button>(R.id.submit_button)
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        AccessCheckoutEditText panAccessCheckoutView = findViewById<AccessCheckoutEditText>(R.id.card_flow_text_pan);;
        AccessCheckoutEditText cvcAccessCheckoutView = findViewById<AccessCheckoutEditText>(R.id.card_flow_text_cvc);
        AccessCheckoutEditText expiryDateAccessCheckoutView = findViewById<AccessCheckoutEditText>(R.id.card_flow_text_expiryDate);
        Button submit = findViewById<Button>(R.id.submit_button);
    }

}

Validate card details

You can optionally validate your customer's card details. See our instructionshere.

Create CARD session and CVC session

Implementing callbacks

The SDK converts the customer's card details entered within the UI Components. It then creates the CARD session and CVC session and invokes a callback to the implementation class of the SessionResponseListener interface.

You must create a class that implements our SessionResponseListener interface.

Your implementation receives notifications once the session request is complete.

You get the session as a Map<SessionType, String> or the exception as a AccessCheckoutException in case of an error.

Here is an example implementation of the SessionResponseListener interface.

package com.worldpay.access.checkout.sample.code

import com.worldpay.access.checkout.client.api.exception.AccessCheckoutException
import com.worldpay.access.checkout.client.session.listener.SessionResponseListener
import com.worldpay.access.checkout.client.session.model.SessionType

class MySessionResponseListener: SessionResponseListener {

    override fun onSuccess(sessionResponseMap: Map<SessionType, String>) {
        //TODO: handle the session response here
    }

    override fun onError(error: AccessCheckoutException) {
        //TODO: handle the exception here
    }

}
package com.worldpay.access.checkout.sample.code

import com.worldpay.access.checkout.client.api.exception.AccessCheckoutException;
import com.worldpay.access.checkout.client.session.listener.SessionResponseListener;
import com.worldpay.access.checkout.client.session.model.SessionType;

public class MySessionResponseListener implements SessionResponseListener {

    @Override
    public void onSuccess(Map<SessionType, String> sessionResponseMap) {
        //TODO: handle the session response here
    }

    @Override
    public void onError(AccessCheckoutException error) {
        //TODO: handle the exception here
    }

}

Initialize the AccessCheckoutClient

You must now initialize the AccessCheckoutClient using the AccessCheckoutClientBuilder.

To do this, you must provide your baseUrl, checkoutID and other parameters. See the table below for more information.

Here's an example of how you would initialize the SDK with the mandatory parameters and configurations.

    private val baseUrl = "TARGET_BASE_URL"
    private val checkoutId = "YOUR_CHECKOUT_ID"

    override fun onCreate(savedInstanceState: Bundle?) {

                .lifecycleOwner(this)
                .build()
    }

public class MainActivity extends AppCompatActivity {

    private String baseUrl = "TARGET_BASE_URL";
    private String checkoutId = "YOUR_CHECKOUT_ID";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // reference views code ommited

        SessionResponseListener sessionResponseListener = new MySessionResponseListener();

        final AccessCheckoutClient accessCheckoutClient = new AccessCheckoutClientBuilder()
                .baseUrl(baseUrl)
                .checkoutId(checkoutId)
                .context(this)

                .lifecycleOwner(this)
                .build();
    }

}

Important: When using the SDK with AndroidX Lifecycle 2.3.0 and above, the call to build() must be done on the main UI thread. This is due to changes to the LifecycleRegistry class used by the SDK which now enforces this constraint.

Mandatory parameters

Generate CARD session and CVC session

You must pass references to the UI Components as well as the SessionType.CARD and SessionType.CVC enums to the generateSessions method on the AccessCheckoutClient instance.

Here's an example of what you should do when your customer clicks the submit button.

        });
    }

}

Caution: Do not validate the structure or length of the session resources. We follow HATEOS standard to allow us the flexibility to extend our APIs with non-breaking changes.

Create a verified token

Once you've received a CARD session you must create averified tokentotake a payment.

Important: The CARD session has a lifespan of one minute and you can use it only once. If you do not create a token within that time, you must create a new CARD session value.

Take a payment

Use the value of the CVC session and the verified token in our card/checkout paymentInstrument to take a card on file payment.

Important: The CVC session has a lifespan of 15 minutes and you can use it only once. If you do not take a payment within that time, you must create a new CVC session value. You can do this with ourCVC only SDK.

This paymentInstrument can be used in ourCard Payments API endpoint.


Need to create a session for CVC only? Take a look at our integration example below:

Create a session for CVC only

Full sample integration: You can see an example of the session generationhere.

Set your views

When you create your checkout form, you must add the views that your customers use to enter their card details and set unique identifiers for each of them.

As part of our SDK, we provide a UI Component dedicated to capturing your customer's card details to minimize your exposure to PCI Data.

You must use this component if you want to qualify for the lowest level of PCI compliance (SAQ-A).

    }

}

Validate CVC details

You can optionally validate your customer's CVC. You can find instructionshere.

Create a CVC session

Implementing callbacks

The SDK retrieves the customers card details from the UI Components. The SDK then creates the session and invokes a callback to the implementation class of the SessionResponseListener interface.

You must create a class that implements our SessionResponseListener interface.

Your implementation receives notifications once the session request is complete.

You get the session as a Map<SessionType, String> or the exception as a AccessCheckoutException in the case of an error.

Here is an example implementation of the SessionResponseListener interface.

Initialize the AccessCheckoutClient

You must now initialize the AccessCheckoutClient using the AccessCheckoutClientBuilder.

To do this, you must provide your baseUrl, checkoutId and other parameters. See the table below for more information.

Caution: Do not validate the structure or length of the session resources. We follow HATEOS standard to allow us the flexibility to extend our APIs with non-breaking changes.

Take a payment

Use the value of the CVC session and your stored verified token in our card/checkout paymentInstrument to take a card on file payment.

Important: The CVC session has a lifespan of 15 minutes and you can use it only once. If you do not take a payment within that time, you must create a new CVC session value.

This paymentInstrument can be used in ourCard Payments API endpoint.
