When integrating Google Pay via Cybersource, you will need to specify Cybersource as the payment gateway as in the below:

const tokenizationSpecification = {


  parameters: {

    'gateway': 'cybersource',

    'gatewayMerchantId': 'apexx_merchant_id'



Please reach out to your implementation contact to confirm what your gatewayMerchantId should be.

The Google Pay response then needs to be Base64-encoded. The result of this encoding should then be sent in the encrypted_payment_data field in the request to APEXX.
