Marriott TIP Internet Portal API
Partner-facing API used by Marriott's in-hotel internet (TIP) provider integration to generate a guest landing-page URL, validate a guest's room number and last name against the cloud PMS, and post an internet purchase back to the PMS. Bearer and Basic security schemes are declared and an SSO token operation is included. This is not part of any public Marriott developer program; the OpenAPI document is readable on SwaggerHub under the "marriott-api" owner and the only server it names is a Marriott UAT gateway host that is not open to the public.
