  <warnings>
        <warning>We excluded the following rooms from the result, because they have no room-level availability and the request contained room_level=1. room_ids: 12301, 12303</warning>
  </warnings>
</result>

Notes:

  • Booking.com generally handles availability at room level. If you request availability information at rate level for a property with a room level inventory, the response is likely to be inaccurate.
  • If you use room_level=1, the API ignores rooms that have no room-level availability. See the warning in the sample above.

Response body example (room_level = 0)

<result>
    <roomrate
      booked="0"
      cancelled="0"
      closed="0"
      date="2018-09-19"
      rate_id="12345678"
      room_id="12302"
      rooms_to_sell="2"/>
    <!-- More <roomrate> elements would follow here. Skipped for brevity. -->
