Availability and Restrictions

HotelRunner will receive updates for availability and restrictions via the OTA_HotelAvailNotifRQ message. HotelRunner will add the updates to their queue to process and respond with the OTA_HotelAvailNotifRS as a receipt of success or failure to add queue the request.


The OTA_HotelAvailNotifRQ message can be used to update the availability and restrictions for one room type for a single property. Specifically:

  • Room availability
  • Stop sell or 'close out' of a room
  • Closed to arrival
  • Closed to departure
  • Minimum stays

Each OTA_HotelAvailNotifRQ message must contain a single AvailStatusMessages element to indicate the property to update using the AvailStatusMessages/@HotelCode attribute. The AvailStatusMessages/AvailStatusMessage elements will contain the updates to process over a date range. There can be several AvailStatusMessage updates per request, however each request must be limited to one property.

The basic structure of the message is as follows:
