Sign In Enterprise (formerly Traction Guest, now part of Sign In Solutions) is an enterprise visitor management system (VMS) used by security-conscious organizations in aerospace and defense, government, manufacturing, pharmaceuticals, and technology. Its REST API — branded "Guest Connect" and published as the Sign In Solutions VMS API — lets developers retrieve and modify visitor and employee sign-in data to extend workflows: managing hosts, invites, sign-ins, registrations, locations, capacities, parking, group visits, watchlists, email templates, and audit logs. The API is REST over JSON, secured with OAuth 2.0 / OpenID Connect scoped access, and supports idempotent writes via an Idempotency-Key header.
