When integrating Google Pay via Cybersource, you will need to specify Cybersource as the payment gateway as in the below:
const tokenizationSpecification = {
type: 'PAYMENT_GATEWAY',
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.
