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.
