Transient Token Time Limit

Transient Token Time Limit
The sensitive data associated with the transient token is available for use only for 15 minutes or until one successful authorization occurs. Before the transient token expires, its data is still usable in other non-authorization services. After 15 minutes, you must prompt the customer to restart the checkout flow.
When the customer submits the form,
Microform Integration
securely collects and tokenizes the data in the loaded fields as well as the options supplied to the
function. The month and year are included in the request. If tokenization succeeds, your callback receives the token as its second parameter. Send the token to your server, and use it in place of the PAN when you use supported payment services.
