Session object
A session is the applicant-facing intake container. It stores the signed hosted URL, case type, linked case, answer state, document state, and submission status.

Lifecycle
Create a session from trusted server-side code. Redirect the applicant to the signed URL. Subscribe to webhook events for state changes, and read current state from the API when you need the latest record.
Klarefi also opens a session itself for each request in an email to your connected mailbox, with the email and its files as the case's documents, and when a declined applicant follows an invitation to apply again. Those sessions send the same events and end in the same case package. See Email intake.
