CTM Portal Host API is published by [Corporate Travel Management](https://apis.io/providers/corporate-travel-management/) on the [APIs.io](https://apis.io/) network. Tagged areas include Corporate Travel, Travel, Booking, and Undocumented. The published artifact set on APIs.io includes authentication docs.

The private back-end API for CTM Portal, CTM's single sign-on customer portal. It is not documented, not announced and not offered to third parties — it was identified from the portal's own client bootstrap, which sets hostApiUrl to https://portal-host.api.ctmsmart.com/api. The host is live (GET / and GET /api return HTTP 200 text/plain "Healthy") and is an ASP.NET Core application that emits RFC 7807-style application/problem+json errors, but every specification path — /openapi.json, /swagger.json, /swagger/v1/swagger.json, /api-docs, /graphql — returns 404, and no /.well-known/oauth-protected-resource metadata is served. Calls are bearer-token protected through CTM's Auth0 tenant (travelctm-au-production.au.auth0.com), whose OIDC discovery document is the only anonymous machine-readable surface CTM operates. Recorded here as an observed, undocumented integration surface, not as an available API: there is no developer sign-up, no documentation, no sandbox and no terms permitting third-party use.
