Parameters

Name

Type

Description

api_version

integer

The version of the API of this request.

start_date

string

The check-in date of the traveler using the hotel's time zone. The date is required to be in ISO8601 full-date format (YYYY-MM-DD).

end_date

string

The check-out date of the traveler using the hotel's time zone. The date is required to be in ISO8601 full-date format (YYYY-MM-DD).

party

array

Array of JSON objects representing number of adults and children traveling.

key	description	type
adults	The number of adults staying in the room.	integer
children	[Optional] The ages of any children staying in the room. If no children are requested Tripadvisor may send an empty children array. For example: "party":[{“adults": 2}{children:[]}]. Or no children at all. Both variants should be accepted.	integer array

Each Party object represents a request for a separate room. For example, "party":[{“adults": 2}] is a request for 1 room that accommodates 2 adults, or "party":[{"adults": 3},{"adults": 2, "children": [9,5]}] is a request for 1 room for 3 adults and 1 room for 2 adults and 2 children for a total of 2 rooms.

language

string

Language code (see Supported Languages). Language codes are a combination of the ISO 639-1 language codes and the ISO 3166-1 country codes. When used in an AvailabilityRequest, this is the language that Tripadvisor would prefer that the partner return with. When used in an AvailabilityResponse, this is the language that the partner is responding with.

If the partner does not have the language of the request, they can return a less specific language. e.g. If the request is asking for de_AT, then the response can be de.

query_key

string

String useful for debugging. It is recommended for this value to be logged.

currency

string

ISO 4217 currency code.

user_country

string

ISO 3166-1 alpha-2 country code.

device_type

string

Identifies the user’s device type. Takes values “Desktop”, “Mobile” or “Tablet”. This value is required if pricing differs by device type.

query_key

string

String useful for debugging. It is recommended for this value to be logged.

availability_id

string

Identifier primarily used for internal purposes. Partners implementing the API may ignore this parameter.

requested_payload

array

Each of these flags correspond to particular sets of information in the response. Currently Tripadvisor will always set the requested flag as False in Hotel Availability search. You are free to return whichever content you would like however at this time only Free Cancellation, Pay at Stay and Breakfast Included information is used in Hotel Availability. Additional content beyond that is displayed only for Instant Booking.

At this time Tripadvisor requests that partners only return a False flag, irrespective of the content you return, as a result you can ignore the below information.

In the request, this signifies that these pieces of information are required. In the response, these flags indicate this information has been given to the best of your ability, there is not another call which will provide better information.

Scenario	Requested Flag	Acceptable Response Flag	Explanation and expectations
1	False	False	Partner is responding with the exact set of data being requested.
2	False	True	Partner is capable of responding with more data than what was asked in the request. This may be useful in case a Partner's system does not allow you split content per the Tripadvisor requirements.
3	True	True	Partner is providing the required pieces of information to the best of their knowledge. Best case, Partner provides all the content requested.
4	True	False	Partner cannot provide this information at this time, either due to an error in the partner's system / load capabilities. Tripadvisor may be unable to display the rest of your content.

Example: in a single hotel request with all flags set to false - i.e TA is requesting at least one room-rate to be returned (assuming there is availability for that hotel). Potential response options:

At minimum we expect to receive a single room-rate with the response flags set to all be false.
However, for the same request, a Partner is permitted to send TA more information. For example, Partner can potentially send all room-rates (instead of just one) for that hotel. Here a Partner is expected to set the "multiple_room_rates_included" to "true"

Example: the request has flags for "room_type_details" and "photos" set to "true. Acceptable responses where Partner sets "room_type_details" and "photos" flag to "true"

Partner provides photos for each room type
It is possible that the partner just does not have access to / full coverage for the content being requested. It is expected that the response flags for "photos" and "room_type_details" are set to "true" but the payload returned may not contain any photos. Partner is indicating that they understand the requested fields, are trying to provide that data to us, and there is no better content available in a separate call or otherwise

Responses should include as much extra information as they can without incurring significant costs in time the call takes or rate of calls supported. If any of these fields are missing they will be interpreted as false. New flags may be added in the future in which case they should either not be returned or returned as false.

Response

The below represents the minimum amount of information you can provide in order to be displayed in Tripadvisor's Hotel Availability search.

Currently Tripadvisor will always set the requested flag as False in Hotel Availability search. You are free to return whichever content you would like however at this time only Free Cancellation, Pay at Stay and Breakfast Included information is used in Hotel Availability. Additional content beyond that is displayed only for Instant Booking.

Properties

Field	Type	Description
api_version	integer	The version of the API of this response.
language	string	Language code (see Supported Languages). Language codes are a combination of the ISO 639-1 language codes and the ISO 3166-1 country codes. When used in an AvailabilityRequest, this is the language that Tripadvisor would prefer that the partner return with. When used in an AvailabilityResponse, this is the language that the partner is responding with. If the partner does not have the language of the request, they can return a less specific language. e.g. If the request is asking for de_AT, then the response can be de.
availability_request	array	The request parameters.
response_payload	array	The response parameters.
hotels	hotels map	Map of partner_hotel_code to SingleHotelResponse entries. See below.

Hotels

Map of partner_hotel_code to SingleHotelResponse entries. Each key must match a corresponding partner_hotel_code in the request's hotel array. Note that each hotel may have a different response_type. This Map must be the same size as the list of the hotels in the request to be considered a valid response.

Field	Type	Description
response_type	string	The type of response returned for a hotel. Must be one of "available", "unavailable" or "error"
available	SingleHotel map	Representation of an individual hotel. Only if response_type is "available".
error	Error object	Only if response_type is "error". See Error.

RoomTypes

Field	Type	Description
room_types	RoomType map	Affected when all flags below are true: multiple_room_rates A map from room type keys to room types. At minimum, there must exist a room type entry for every unique room_type_key used in room_rates RoomRate objects.

Field Type Description

persistent_room_type_code

string

This code identifies unique room types. We expect that this code persists across future availability calls. The combination of persistent_room_type_code and partner_hotel_code must be unique.

name

string

The name of this room type. Room names must summarize 1-2 significant selling points for the room, ideally in less than 50 characters. For example, you can include the bed type configuration information and the room view in the name (e.g. “One Bedroom Suite, One King Bed”, “Courtyard King”, “Garden View Room, King”, “King Studio”); or simply match the room name to brand.com

If a room name consists of only numbers and symbols, or is shorter than 4 characters, it will be blocked from Instant Booking.

description

string

Provide when all flags below are true:

room_type_details
text

Longer room description. This will be displayed to end users, and should be in the language indicated by the lang parameter. Ideal room descriptions are 250-400 characters in length. They are written in third person voice and highlight selling point for the room. For example, "This one-bedroom suite has a king bed. This corner suite also features a separate living room with a sofa bed, a well-equipped kitchen with complimentary grocery delivery services, and Paul Mitchell bath products."

Language specific requirements will be applied. For example, if a room description in English consists of only numbers and symbols, or is shorter than 4 characters, it may be blocked. See supported HTML tags.

photos

Photo array

Provide when all flags below are true:

room_type_details
photos

List of photos of the room.

Image file type should be able to render on modern web browsers (JPG, PNG, GIF) (TIFF is not supported). Photos should support https.

room_amenities

object

Provide when all flags below are true:

room_type_details

Array of number codes. Each code corresponds to an amenity for the OpenTravel Hotel Amenity Code List. A map of the standard room amenities is listed under the Supported Amenities section. Hotel and room amenities are provided in separate parts of the response, and should not overlap. For example, amenities that have no bearing on the room (e.g. “free parking”) should not be included as a room amenity, but rather as a hotel amenity. We recommend rooms offer a minimum of 10 amenities.

The standard amenities will be returned as an integer array. If an amenity does not exist in the Supported Amenities list, then the Connectivity Partner may provide their own values. Return "custom":[ ] if no custom list exists.

Example:
{ "standard": [1 ,2, 5, 20, 60,], "custom": ["myamenity1", "myamenity2"] }

max_occupancy

map of string:int

Provide when all flags below are true:

room_type_details

Maximum number of guests permitted in the room. {"number_of_adults": <num_adult>, "number_of_children": <num_child>}.

Example: {"number_of_adults": 3, "number_of_children": 2 }.

room_size

map of string:int

Provide when all flags below are true:

room_type_details

Area of room in given units. If given, both value and unit are required.

Example: {"value":500, "unit": "square_feet" }

bed_configurations

object

Provide when all flags below are true:

room_type_details

A list of one or more possible configurations.

In order for a bed configuration to be valid, at least one element must exist in either the standard array or custom array.
Two or more configurations mean that the room could be configured to contain either (any) of these set ups.

For example, the following snippet illustrates how to represent two bed configurations, either one king bed OR two double beds:

"bed_configurations": [
  { "standard": [ { "count": 1, "code": 3 } ] },
  { "standard": [ { "count": 2, "code": 1 } ] }
]

The following snippet illustrates how to represent one bed configuration, with a crib AND a custom bunk bed:

"bed_configurations": [
  { "standard": [ { "count": 1, "code": 900302 } ],
    "custom": [ { "count": 1, "name": "Bunk bed"} ] }
]

Specify the bed types for a room, and if needed multiple bed configurations available. The type of bed provided is based on OpenTravel BED code table:

1	Double
2	Futon
3	King
4	Murphy Bed
5	Queen
6	Sofa Bed
7	Tatami Mats
8	Twin
9	Single
10	Full
11	Run of the House
12	Dorm Bed
900301	Roll-Away Bed
900302	Crib
900303	Unspecified Bed

extra_bed_configurations

In order for an extra bed configuration to be valid, at least one element must exist in either the standard array or custom array.
Two or more configurations mean that the room could be configured to contain either (any) of these set ups.

For examples, see bed_configurations.

Multiple Rooms

This example demonstrates how to work with multiple parties and multiple rooms.

The availability response is exactly the same whether a single room (single object in the ' party' array) or multiple rooms (multiple objects in the ' party' array) are in the availability request.

There are, however, some considerations as follows.

Using this as an example party array in the request: [{"adults": 3},{"adults": 2}], you can follow these guidelines when constructing the response:

When we request multiple rooms you should send all rooms that can accommodate the largest party.
In this case, you should respond with all available rooms that can accommodate 3 adults or more.
You should not send rooms that can accommodate only 2 adults or less.
You should also send only the room types that have available a number of rooms equal or greater than the number of parties. In this case there are two parties.
The prices should be the total for the number of days and party. We will then divide it and come up with the price per night and per guest.

Another example party array might look as follows: [{"adults": 1},{"adults": 2},{"adults": 4}]
You should return all the room types that can accommodate the maximum number of adults (in this case 4) and have available at least the same number as the number of rooms requested (in this case 3).

Suppose that a hotel has a room type called “Double suite” that can accommodate 4 adults and a room type called “Large Double suite” that can accommodate 6. Both these room types could be returned in the response if the hotel has at least 3 rooms available of each.

All room types that can accommodate 1 or 2 adults maximum have to be excluded, and all room types that have less than 3 rooms available also have to be excluded.

No availability

So for no availability, Tripadvisor would expect to see:

...
"response_type": "unavailable"
...

Merchandising

The below describes the implementation of 'Free Cancellation', 'Pay At Stay' and 'Breakfast Included' merchandising shown on Tripadvisor Hotel Availability search. Please note that the information below is only applicable for Hotel Availability response. Merchandising will only be shown if your cheapest rate is free to cancel and/or pay at stay and/or breakfast included. There is currently no merchandising for non-refundable or partially-refundable rates. Information must be correct on the partner's landing page. Partners should only support this feature if it has minimal to no impact on their response time. You should continue to return "requested_payload" flags as false as well as sending "persistent_room_type_code" and "persistent_rate_plan_code". For merchandising to be eligible it is required that "persistent_room_type_code" and "persistent_rate_plan_code" be populated and not be returned empty.

Free Cancellation

To be eligible for 'Free Cancellation' merchandising your Hotel Availability response should return cancellation_policy in RatePlans. Not all objects in cancellation_policy are required, to reduce complexity it is recommended that you only send the following:

cancellation_policy

object

"cancellation_policy": {
  "cancellation_summary": {
    "refundable": "full",
    "cancellation_deadline": "2019-06-15T00:00:00Z"

Must be one of:

none - "no refund provided if cancelled"
full - "There exists a time between time of booking and time of arrival where the reservation may be cancelled without any charge to the user. Reservations whose free cancellation expires within N days of time of arrival may still be marked fully refundable unless time of booking is within N days of time of arrival"

Note: These fields are case sensitive and should be set as displayed above, they should not be for example 'Full' or 'None'.

cancellation_deadline

string

Pay at Stay

To be eligible for 'Pay At Stay' merchandising your Hotel Availability response should return "paid_at_checkout" : true for all LineItems:

            "line_items": [
              {
                "price": {
                  "requested_currency_price": {
                    "amount": 220,
                    "currency": "USD"
                  }
                },

                }
            ]
          },

Breakfast Included

Partners can indicate which meals are included in the quoted price via the "meal_plan" object in the associated rate plan. For partner offers to be eligible for “Breakfast included” offer-level merchandising, you will need to return a standard meal_plan code that represents a breakfast inclusion:

Code	Meaning
3	Bed & breakfast
4	Buffet breakfast
5	Caribbean breakfast
6	Continental breakfast
7	English breakfast
11	Full breakfast
19	Breakfast

            },
