A session is created when you log into a web service and it authenticates you as a user. Such a session can last for any period of time, which - in our case - is typically determined by the payroll system you are connecting with. While the session is still active, the data can be refreshed automatically.
Typically, the Citadel Bridge can keep a session alive for 6 hours. Please reach out to us at email@example.com for any customization requests regarding session alive duration.
