Advanced Options

You can manage this by updating CheckoutSkipCVVMode of CheckoutSettings class:

• CheckoutSkipCVVMode.NEVER - Always request CVV for card payments. This is set by default.
• CheckoutSkipCVVMode.FOR_STORED_CARDS - Skip CVV check only for payments by stored cards.
• CheckoutSkipCVVMode.ALWAYS - Always skip CVV check. CVV field won't be displayed in card payment forms.

CheckoutSettings checkoutSettings = new CheckoutSettings(checkoutId, paymentBrands, providerMode);
checkoutSettings.setSkipCVVMode(CheckoutSkipCVVMode.FOR_STORED_CARDS);

CheckoutSettings checkoutSettings = new CheckoutSettings(checkoutId, paymentBrands, providerMode);
checkoutSettings.setCardHolderVisible(false);

Protect payments with device authentication

You can provide additional security for your shoppers by enabling payment confirmation with device authentication.
To complete payment shopper will have to provide their credentials (Pattern, PIN, Password or Fingerprint if available).

It's recommended to enable this protection for tokens (stored cards and back account information).
Protection with device authentication can be configured for any payment brands as well.

1. Never CheckoutSecurityPolicyMode.DEVICE_AUTH_NOT_REQUIRED
Device authentication is disabled.
2. If available CheckoutSecurityPolicyMode.DEVICE_AUTH_REQUIRED_IF_AVAILABLE
App requires device authentication only if it is set by user.
3. Always CheckoutSecurityPolicyMode.DEVICE_AUTH_REQUIRED
Device authentication is required to complete payment. Payment brand won't be available if device is not secured, i.e. Pattern, PIN, Password or Fingerprint is not set.

You can configure device authentication per payment brand. For example:

Set<String> paymentBrands = new LinkedHashSet<String>();

paymentBrands.add("VISA");
paymentBrands.add("MASTER");
paymentBrands.add("DIRECTDEBIT_SEPA");

CheckoutSettings checkoutSettings = new CheckoutSettings(checkoutId, paymentBrands, providerMode);

checkoutSettings.setSecurityPolicyModeForBrand("VISA", CheckoutSecurityPolicyMode.DEVICE_AUTH_REQUIRED);
checkoutSettings.setSecurityPolicyModeForBrand("MASTER", CheckoutSecurityPolicyMode.DEVICE_AUTH_REQUIRED_IF_AVAILABLE);

Set device authentication for tokens:

checkoutSettings.setSecurityPolicyModeForTokens(CheckoutSecurityPolicyMode.DEVICE_AUTH_REQUIRED);

By default total amount is not shown in ready-to-use UI. Since version 2.23.0 you can enable this option by setting boolean property isTotalAmountRequired of CheckoutSettings class.

CheckoutSettings checkoutSettings = new CheckoutSettings(checkoutId, paymentBrands, providerMode);
checkoutSettings.setTotalAmountRequired(true);

Implement IPaymentFormListener listener to catch payment form events and pass it to the CheckoutSettings.
Listener also should implement Parcelable interface as it will be passed through intent.

// Create your listener to override holder validation
public class CustomFormListener implements IPaymentFormListener {
    public CustomFormListener() {}
    
    @Override
    public CheckoutValidationResult onCardHolderValidate(String holder) {
        // Your intenal validation here
        if (isHolderValid(holder)) {
            return CheckoutValidationResult.VALID;
        } else {
            return CheckoutValidationResult.NOT_VALID;
        }
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel parcel, int i) {}
    
    private CustomFormListener(Parcel in) {}

    public static final Creator<CustomFormListener> CREATOR = new Creator<CustomFormListener>() {
        @Override
        public CustomFormListener createFromParcel(Parcel in) {
            return new CustomFormListener(in);
        }

        @Override
        public CustomFormListener[] newArray(int size) {
            return new CustomFormListener[size];
        }
    };
}

Pass created listener to the CheckoutSettings.

CheckoutSettings checkoutSettings = new CheckoutSettings(checkoutId, paymentBrands, providerMode);

CustomFormListener listener = new CustomFormListener();
checkoutSettings.setPaymentFormListener(listener);

To display installment options configure CheckoutSettings in the following way:

• Enable installment payments
• Set your list of options if needed. Default is 1, 3, 5.

CheckoutSettings checkoutSettings = new CheckoutSettings(
        checkoutId, paymentBrands, providerMode);

checkoutSettings.setInstallmentEnabled(true);
checkoutSettings.setInstallmentOptions(new Integer[] { 1, 2, 3 });

Summary page

It is possible to use Mobile SDK to temporarily store the payment information after submission, rather than executing it straight away. This can be useful if you want to display an order summary page before committing the payment. For this purpose, you should implement your broadcast receiver to listen the intents from CheckoutActivity and use CheckoutActivity.ACTION_ON_BEFORE_SUBMIT callback to display the summary page.

public class CheckoutBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();

        if (CheckoutActivity.ACTION_ON_BEFORE_SUBMIT.equals(action)) {
            String checkoutId = intent.getStringExtra(CheckoutActivity.EXTRA_CHECKOUT_ID);
            ComponentName senderComponentName = intent.getParcelableExtra(
                    CheckoutActivity.EXTRA_SENDER_COMPONENT_NAME);
            
            /* Display the summary page. */
            Intent summaryPageIntent = new Intent(context, SummaryPageActivity.class);
            summaryPageIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            summaryPageIntent.putExtra(OrderReviewActivity.EXTRA_CHECKOUT_ID, checkoutId);
            summaryPageIntent.putExtra(OrderReviewActivity.EXTRA_SENDER, senderComponent);
            context.startActivity(summaryPageIntent);
        }
    }
}

The summary page should consist of at least two actions:

1. Confirm payment. You should just return control back to the CheckoutActivity to submit the payment.

intent = new Intent(CheckoutActivity.ACTION_ON_BEFORE_SUBMIT);
intent.setComponent(senderComponentName);
intent.setPackage(senderComponentName.getPackageName());
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(CheckoutActivity.EXTRA_CHECKOUT_ID, checkoutId);
startActivity(intent);

2. Cancel payment. In this case the CheckoutActivity should be started with CheckoutActivity.EXTRA_TRANSACTION_ABORTED flag. Then checkout will be closed with ErrorCode.ERROR_CODE_TRANSACTION_ABORTED code.

intent.putExtra(CheckoutActivity.EXTRA_TRANSACTION_ABORTED, true);
startActivity(intent);
