  description: pmsXchange is SiteMinder's integration API for property management systems (PMS), revenue management systems
    (RMS), and central reservation systems (CRS) that need to synchronize rooms, rates, availability, restrictions, reservations,
    and payment data with SiteMinder's distribution network. Built on OpenTravel Alliance message schemas, pmsXchange handles
    two-way exchange of hotel inventory and bookings between the property's system of record and SiteMinder's channel manager,
    supporting push, pull, upload, and import patterns for reservation processing. Certified pmsXchange partners gain access
    to SiteMinder's Hotel App Store and distribution across more than 47,000 connected properties.

  description: SiteConnect is SiteMinder's integration API for booking channels such as online travel agencies, wholesalers,
    global distribution systems, and metasearch partners that contract directly with hotels. The API uses OpenTravel Alliance
    message schemas (OTA_HotelAvailNotifRQ, OTA_HotelRateAmountNotifRQ, OTA_HotelResNotifRQ) and is organized into four resource
    areas - Rooms and Rates, Availability and Restrictions, Rates, and Reservations - exchanged through both pull and push
    patterns over global endpoints. SiteConnect partners must complete SiteMinder's testing and certification program before
    gaining production access and become eligible for distribution to properties via individually-negotiated channel contracts.

  description: Channels Plus is SiteMinder's REST and JSON booking channel API that lets partners connect to many SiteMinder
    properties through a single integration without negotiating individual hotel contracts. It exposes property search, real-time
    shopping for rates and availability, and a full reservation lifecycle - lock, confirm, modify, cancel, list, and detail
    - alongside a companion Model Context Protocol (MCP) server that gives AI agents access to the same shopping and booking
    surface. Partner onboarding is automated through a dedicated portal where channels manage deals, invoicing, cancellations,
    and the Net Rates Program for wholesale-style distribution.

  description: The Direct Booking API is a REST and JSON service that lets hotel groups on SiteMinder's Multi-Property platform
    power custom direct booking flows on their own websites and mobile apps. It exposes property listings, individual property
    detail, room types, room rates, and quote generation so developers can build branded availability search, shopping, and
    pricing experiences that pull live data from SiteMinder. API access is gated by per-tenant API keys generated and managed
    through the SiteMinder dashboard; the API is not available to groups on the classic SiteMinder Channel Manager.
