Justworks Webhooks API

Manage Justworks Partner API webhooks. Justworks signs every request, delivers events at-least-once with automatic retries, and closes a webhook on sustained failures (resumable via API). Event types cover member.profile.*, member.employment_state.termination_*, and department.* lifecycle changes. A Tour-environment simulate endpoint allows partners to validate their listener without real data.
