Horizon Web Services (HWS)
XML Interface to SITA Hosts Systems
SITA airline customers often have to develop and deploy their own secure in-house apps using data from Reservations, Fares, DCS and Ticketing.
Horizon Web Services (HWS) is a component of the SITA Horizon Passenger Services System (PSS) and provides consistent and reliable access to SITA’s host systems via a standard Application Programming Interface (API) which is based on a set of structured messages. This API enables airline customers to deploy their own reliable, secure and robust applications such as internet booking engines, kiosks and customized reservation agent applications that adhere to industry standards.
HWS is platform independent and is based on the OpenTravel™ Alliance (OTA) XML standards.
