Sign In Enterprise

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.

Sign In Enterprise publishes 14 APIs on the APIs.io network, including AuditLogs API, Batches API, Capacities API, and 11 more. Tagged areas include Company, Vertical Software, Visitor Management, Physical Security, and Workplace Experience.

The Sign In Enterprise catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Sign In Enterprise’s developer surface includes documentation, API reference, pricing, engineering blog, support, authentication, and 25 more developer resources.
