AlpineBits HotelData

AlpineBits HotelData is an interface specification for the exchange of tourism data developed with a special focus on, but not limited to, Alpine tourism and based on OTA (OpenTravel Alliance) 2015A.
The standard is released under the CC-BY-SA licence.

Since 2011, the AlpineBits Alliance has developed and maintained the HotelData standard through regular releases. The latest version, AlpineBits HotelData 2026-10, was officially released on 22nd October 2026.

Data that can be exchanged through the standard includes: room availability, booking requests, reservations/cancellations, rates, images and licence metadata, descriptions and information on room and accommodation categories.

There are currently more than 125 known implementations using the AlpineBits HotelData standard.

In 2020, the standard facilitated the exchange of booking requests and reservations worth over €60 million. In the same year, a single Alliance member exchanged more than 4.5 million messages using the standard.

Important notice AlpineBits HotelData versions prior to 2018-10 are no longer supported. Organisations still using these versions are strongly encouraged to migrate to a supported release to ensure compatibility with the latest standard.
