    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

      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.
