description: 'Symmetry provides webhook notifications for two product areas: Guides (tax change updates) and I‑9 (employment eligibility). The
  Guides webhook does not list specific event names, only that a webhook fires when a new tax or tax rate is published. The I‑9 webhook surface
  lists the following event keys:'
events:
- event: employee.i9Complete
  description: Notifies you when an employee's I‑9 is complete and Section 2 is countersigned.
- event: employee.everifyCaseUpdate
  description: Triggered when an employee’s E‑Verify case is updated.
- event: employee.profileUpdated
  description: Notifies you when an employee's profile is updated (e.g., social security number added).
- event: employee.upcomingExpiration
  description: Triggers for Employment Authorization Documents and Passport receipts 30 days before expiration, or immediately upon I‑9 submission
    if within 30 days.
- event: employee.i9Restarted
  description: Notifies you when an employee restarts the Form I‑9 process.

delivery:
  content_type: application/json
note: The Guides webhook documentation does not specify a signature header or authentication mechanism; it only states that a JSON notification
  is sent when a new tax or tax rate is published. The I‑9 webhook documentation similarly does not mention a signature header or authentication
  method; it describes the POST payload format only.
