  title: Booking.com Connectivity Rates and Availability API
  description: >-
    The Booking.com Connectivity Rates and Availability API allows Connectivity
    Partners to set room availability, pricing, and restrictions for properties
    on Booking.com. Partners can manage advance booking windows, length of stay
    requirements, and rate plans programmatically. This API is a core component
    of the Connectivity suite, enabling channel managers and property management
    systems to keep inventory and pricing synchronized between their platforms
    and Booking.com without manual extranet updates. Properties should specify
    availability at least 12 months in advance. The API uses XML request and
    response formats following B.XML and OTA specifications.
