Transient Tokens

The response to a successful customer interaction with
Unified Checkout
is a transient token. This is returned in the response from the
unifiedPayment.show()
function. The transient token is a reference to the payment data collected on your behalf. Tokens allow secure card payments to occur without risk of exposure to sensitive payment information. The transient token is a short-term token that expires after 15 minutes. This reduces your PCI burden/responsibility and ensures that sensitive information is not exposed to your back-end systems.
Transient tokens can be included requests sent to the Payment Details and Payment Credentials APIs in exchange for the customer payment data that is collected. This data can include the payment account number (PAN) or tokenized credentials.
