Change Log
# New Features
For technical details, such as sample output for each feature, please view the [technical documentation](chttps://developers.booking.com/api/technical.html?).
# For all versions:
## 🔴 **Starting from 01-08-2023** 🔴
As part of our ongoing efforts to enhance the stability and reduce latency in accessing our static and dynamic content,
we are performing a migration in our network infrastructure.
This transition will provide several benefits, including improved performance and faster response times for your API requests.
**As per the migration, following limitations will apply to all API users;**
- a maximum URL limit of 8192 characters apply to all versions. Consumers of /hotels and /hotelAvailability endpoints are advised to limit number of hotel_ids sent as input to not exceed the URL limit.
- HTTP GET requests may not contain a request body.
In both cases, violations will result in an HTTP 403 error code.

},
```
* Added **"additional_policies"** in **"hotel_data"** for children and extra bed policies. Sample:

"price": 0,
"rate_type": "existing_bed"
}
],
"children_allowed": "true"
}
```

"max_children": 2,

},
```
* Within **"room_info"**, the **"max_persons"** and **"children_policy"** output parameters have both been deprecated.

"price": 322
}
],
```
* Added **"max_adults"** inside the **"block"** object to indicate the maximum number of adults allowable for the block.
___Note___: while allocating guests to the room, make sure the constraint: ( number of children + number of adults = **"max_occupancy"** ) must be met. In the following sample, this room allows a combination of *3 adults*, or *2 adults 1 child*, or *1 adult 2 children*. Sample:
```
"max_adults": 3,
"max_occupancy": 3,
"max_children_free_age": 17,
"max_children_free": 2,
```
* Added new child blocks as output parameters. The only noticeable difference is with **"block_id"**, where the last section is non-zero. Sample:
```
"block_id": "6506324_275664888_3_1_6047313952768",
```
* Removed the **"bed_configurations"** parameter from the **"block"** object as the information returned is inaccurate.
## /bookingDetails

* Changed **"guest_city"** to **"booker_city"** as an output parameter.
* Added **"guest_name"** that returns all names of guests in a booking (if available).
* Added **"smoking_preference"** as an output parameter; can be 'undefined', 'smoking' or 'non-smoking'.

* Added **"nr_guests"** that returns number of guests for each room of a booking.
* Added **"guest_email"** that returns email of guest(s).
* Added **"user_device"** with possible values of "Computer", "Mobile", "Tablet", or "Unknown".
* Added **"extra_charges_breakdown"** that provides all extra charges relevant to a booking. Sample:
```
extra_charges_breakdown":{
"extra_charge":[
{
"amount": 26.34,
"charge_amount": 9,
"charge_price_mode": 5,
"currency": "EUR",
"excluded": false,
"name": "VAT",
"name_id": 21
},
{
"amount": 20.49,
"charge_amount": 7,
"charge_price_mode": 5,
"currency": "EUR",
"excluded": false,
"name": "City tax",
"name_id": 22
}
]
```
* Added **"mealplan"** that provides meal inclusion to a booking. Sample:
```
"mealplan": {
"dinner": {
"price_per_person_per_night": "4.29",
"number_of_persons": 2,
"included": true,
"number_of_nights": 3
},
"lunch": {
"price_per_person_per_night": "4.29",
"number_of_persons": 2,
"included": true,
"number_of_nights": 3
},
"breakfast": {

}
```

```
{
meta: {
ruid: "UmFuxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
has_more: 1
},
result: [
```
## /processBooking
* Added the **"room1"** input to indicate the specific number of adults and children in each room. *room1=A,3* refers to 1 adult and 1 child of 3-year-old. **_Note_**: This conflicts with **"guest_quantities"** (in that these parameters cannot be used together). If child blocks are used then room (number) needs to be used. Otherwise **"guest_quantities"** can be used but child blocks cannot be specified.
* Added validation when both **Online Payments** and **Payment Instructions** are used in the same call. If a partner uses both **"pay_now=1"** and **"vc_company_for_auth_form"** in the same call they will receive the error message. Sample:
```
"errors": [
{
"code": 1009,
"message": "Validation errors: Argument pay_now is exclusive with vc_company_for_auth_form, but vc_company_for_auth_form was defined.; Argument vc_company_for_auth_form is exclusive with pay_now, but pay_now was defined.",
"ruid": "UmFuxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}
]
```
# Version 2.6

Sample:
```

"max_allowed": 1,
"min_age": 2
}
```
**"max_allowed"** is equivalent to **"max_children_free"** parameter and **"max_age"** is equivalent to **"max_children_free_age"** parameter that can be found on **/blockAvailability** endpoint.
## /hotelAvailability
* **"guest_country"** is now a required input parameter.
* It is now possible to limit the results based on the property's facility types by passing the **"hotel_facility_type_ids"** parameter in the request. The full list of the facility type ids can be found in **/hotelFacilityTypes** endpoint.
* Added an output parameter **"platform"** inside **"deal_tagging"** structure on two availability endpoints: **/hotelAvailability** and **/blockAvailability**. The parameter can have two values:
**"Web"** - the price is for mobile web users.
**"App"** - the price is for mobile app users.
## /blockAvailability
* **"guest_cc"** and **"guest_qty"** or **"room1"** are now required input parameters.

Possible values for **"type"** are `mile, point, cash, voucher_money, voucher_subscription` and `voucher_percentage`. Possible values for **"fulfillment"** are `partner` and `booking.com`.
Sample:
```
"loyalty": {
"rewards": [
{
"fulfillment_at_utc": "2020-02-10 00:00:00 UTC",
"currency": "KRW",
"payout_after": 64,
"amount": 119907,
"fulfillment": "partner",
"loyalty_member_data": [
{
"field_value": "abc@gmail.com",
"field_name": "Email"
}
],
"is_eligible": 1,
"type": "mile"
}
]
},
```
* In case of Payments by Booking.com, new output parameters were added: cancellation fee and payment information on the response. Each of them requires a partner setting to be set appropriately in order for those to show.
Output parameters:
**"cancellation_fee"**
**"direct_payment_info"**
* More detailed information about cancellation reason, namely about whether the cancellation was performed by the property or the guest, can be obtained by passing **"extras=status_details"**.
## /processBooking

Input parameters:
**"vc_company_vat_number_for_invoices"**
**"vc_invoice"**
**"vc_invoice_email"**
**"vc_invoice_to_guest"**
* Fixed bug with **"pay_now"** parameter. **/processBooking** will enforce the transaction to be in the Pay Now model when the **"pay_now"** parameter is added. An error message: **_"The requester tried to prepay for a hotel, and the hotel does not accept prepayments."_** will return in the response if the property does not in the Pay Now model.
# Version 2.5
(release date: September 10, 2019)

This feature enables an identifier in the output of availability endpoints. This identifier specifies the public price (the non-discounted rack rate), the discount percentage, and the name of the deal. Sample:
```
