Create or update inventory restrictions

Use the OTA_HotelAvailNotif endpoint to update the following elements in the Booking.com system:

  • The number of rooms available per room type and date combination.
  • Restrictions per room type, rate and date combination.

Difference between OTA_HotelAvailNotif endpoint v1.0 and v1.1

The OTA_HotelAvailNotif endpoint has two versions currently. When migrating to the v1.1 OTA_HotelAvailNotif endpoint, you can view whether a room type is closed. For more information, see RestrictionStatus.

Mandatory elements:

OTA_HotelAvailNotifRQ

All the below XML is fixed and mandatory, except:

timestamp: Contains the current time and date.

target: Specifies either Production or, Test(used for test properties).

  Target="Test"
  Version="1.005">

AvailStatusMessages

The AvailStatusMessages element is mandatory for the OTA_HotelAvailNotif request.

<AvailStatusMessages>
  ...
</AvailStatusMessages>

AvailStatusMessage

BookingLimit (optional): Specifies the number of available rooms to sell for a property.

Make sure to omit the Bookinglimit attribute when updating restrictions in the same AvailStatusMessage block, because a RatePlanCode attribute is mandatory in that case and BookingLimit is updated on room level, not rate level.

You can specify a maximum of 254 rooms to sell. Setting a value greater than 255 implies that there are unlimited rooms available, which means that there is no limit to the number of rooms that can be sold until the room type, rate and date combination is closed with a restriction or until the rooms to sell are decreased again. Setting the value of BookingLimit to 256 or higher, results in 254 rooms to sell in the Booking.com system.

LocatorID (required): Contains a unique ID (used as RecordID in OTA_HotelAvailNotifRS)

<AvailStatusMessage BookingLimit="25" LocatorID="1">

StatusApplicationControl

Start / End (required): Specifies the period (end date is inclusive). Please note, you can update for periods in the future and up to two day in the past, in the Central European Time (CET) timezone.

RatePlanCode: Contains the Booking.com rate category ID. Not required when specifying Bookinglimit in AvailStatusMessage, as the availability is updated on room level.

InvTypeCode (required): Contains the Booking.com room ID.

<StatusApplicationControl Start="2023-11-05" End="2023-11-17" InvTypeCode="36745603" RatePlanCode="1278606" />

Optional elements

LengthsOfStay

Is mandatory when specifying element LengthOfStay.

ArrivalDateBased can be set to 0 or 1. If set to 1, then the restriction set has an effect only on the arrival day of a booking. Whereas, setting it to 0 may affect a search for availability or reservation on all the dates that the query covers. The ArrivalDateBased attribute is optional and the default value is 0.

<LengthsOfStay ArrivalDateBased="0">
  <LengthOfStay ... />
</LengthsOfStay>

LengthOfStay

The minimum or maximum stay for the given room for the given date for the given rate category. If a booking takes place on this day a minimum or maximum stay (for the whole booking or arrival based, depending on ArrivalDateBased="0" or ArrivalDateBased="1") of this amount of days is required. Each day in a stay has a room and rate category ID associated with it. Each set of consecutive days with the same rate category ID in a stay, must comply with the minimum or maximum stay setting.

<LengthOfStay Time="2" MinMaxMessageType="SetMinLOS"/>
<LengthOfStay Time="5" MinMaxMessageType="SetMaxLOS"/>

Removing minimum and maximum length-of-stays

To remove an existing length-of-stay restriction you must send a request to update the minimumstay or maximumstay value to 0. You can encounter the following scenarios:

  • Update only Time="0" for MinMaxMessageType="SetMinLOS" if you want to remove the minimum stay restriction.
  • Update only Time="0" for MinMaxMessageType="SetMaxLOS" if you want to remove the maximum stay restriction.
  • Update both if you want to remove minimum and maximum stay restrictions.

To reinstate restrictions, you must send another request with the value representing the desired amount of days for either or both length-of-stay restrictions.

RestrictionStatus

Mandatory attributes:

Status=""

Using the Status attribute, you can:

  • [Only available in version 1.1] Close the specified room type. The room type will not be available for booking for the specified period, irrespective of whether the room has an open room and rate combination. To close the room type you must not include the RatePlanCode in the request.
  • Close the availability for the specified room type and rate combination by specifying the RatePlanCode in the request.

If set to Close (or Open), the room is closed (or opened) for the specified date. When a room is closed, all other information such as Bookinglimit, prices, and so on is preserved.

Optional attributes:

Restriction=""

The restriction attribute may contain Departure or Arrival.

Where a Close for Restriction Arrival doesn't allow a reservation to be made when guests want to arrive at the selected date. When the restriction is set to Open for a certain date, guests are free to make a reservation with arrival on this date whereas a Close will restrict guests to book rooms with this arrival date.

A Close for Restriction Departure doesn't allow a reservation to be made when visitors want to depart on the selected date. When the restriction is set to Open for a certain date, guests are free to make a reservation with departure on this date whereas a Close will restrict guests to book rooms with this departure date.

MinAdvancedBookingOffset=""
MaxAdvancedBookingOffset=""

MinAdvancedBookingOffset means the minimum time before the checkin date guests will be allowed to make a booking. The maximum supported value is 360D.

MaxAdvancedBookingOffset means the maximum time before the checkin date the guests will be allowed to make a booking. The maximum supported value is 360D.

Both have the same format. The search date is counted as one of the days in the restriction length.

Examples:

  • MinAdvancedBookingOffset="4D" means the room must be booked at least 4 days in advance.
  • MinAdvancedBookingOffset="4H" means the room must be booked at least 4 hours in advance.
  • MinAdvancedBookingOffset="4D4H" means the room must be booked at least 4 days and 4 hours in advance.

To set restrictions using MinAdvanceBookingOffset or MaxAdvanceBookingOffset you must pass a RatePlanCode. If a RatePlanCode is not passed, the API returns an error.

<StatusApplicationControl Start="2023-11-05" End="2023-11-17" InvTypeCode="36745603" RatePlanCode="1278606" />
  <RestrictionStatus Restriction="Departure" Status="Open"/>

The Booking.com responses will contain a RUID string, which is an encoded string used by the Booking.com staff to trace back any updates made before. Whenever the Connectivity Partner wishes the XML-Team to look at any logfiles for debugging or the like; the RUID string needs to be provided. This will enable the Booking.com technical staff to provide Connectivity Partners with support.
