Formatting Encrypted Payment Data

This section shows you how to format encrypted payment data using these procedures:

Configuring Google Pay

You must provide your Cybersource merchant ID to Google in order to ensure proper encryption of the Google Pay payload and authenticity of the request.

For a Google Pay tutorial, see Google Pay for Payments.

Set the gateway and gateway merchant ID to the appropriate indicators. The following code examples show how to configure the

PaymentMethodTokenizationParameters

object using Cybersource as the gateway.

Example: Java Code

.setPaymentMethodTokenizationType(WalletConstants.PAYMENT_METHOD_TOKENIZATION_TYPE_PAYMENT_GATEWAY)
     .addParameter("gateway", "")
     .addParameter("gatewayMerchantId", "[yourCybersourceMID]")

Example: JavaScript Code

tokenizationType: 'PAYMENT_GATEWAY',
     parameters: {
     gateway: 'cybersource',
          gatewayMerchantId: '[yourCybersourceMID]'

Formatting Payment Blobs

IMPORTANT

This section is only applicable if you are using the Cybersource decryption method.

To prepare the Google Pay payload for submission to Cybersource, you must extract the token data element from the Google Pay payload and encode the token data element using Base64.

These samples can be used to Base64-encode payment responses:

JavaScript

let token = paymentData.paymentMethodData.tokenizationData.token;
console.log(token);
var enc=window.btoa(token);

Android with Java

This sample uses the Android Studio Base64 utility.

public static <outputString> encodeToString (byte[] <inputToken>, int DEFAULT)

Apple iPhone with Swift 3

This sample requires the Foundation utility.

extension String {
     func base64Encoded() -> <outputString>
          if let data = self.dat(using:.utf8) {
               return data.base64EncodedString()
          }
          return nil
}
