Jetstar API
The Jetstar API is Jetstar's direct-connect distribution channel for Registered Travel Agents and partners. It is a Navitaire New Skies (NSK) SOAP / WCF web service, not a REST product and not IATA NDC. Jetstar's own partner FAQ publishes the environments as NSK 4.6 with production at https://jqapi.navitaire.com and test at https://soapapir4y.test.jq.navitaire.com, and documents WCF services such as UtilitiesManager.svc alongside session-signature authentication. Operations named in Jetstar's published partner documentation include GetAvailability, GetTripAvailabilityWithSSR, PriceItinerary, GetItineraryPrice, GetSSRAvailability, GetStationList, AddPaymentToBooking, BookingCommit, GetBooking and UpdatePassengers. Documentation, registration, an API Products page and a Download Centre live at apiblog.jetstar.com behind a partner login; no OpenAPI, WSDL or machine-readable contract is published publicly. Access requires IATA accreditation plus separate Jetstar approval, and the service endpoints refuse connections from non-allow-listed clients.
