Hotels and NDC coming soon

The Hotel API and NDC API are in development. Both will use the same API user, authentication, base URL and wallet as Flights.
Flights
Flight API v1.0

First release

  • International flights, one-way and round-trip, in Economy, PremiumEconomy, Business and First.
  • Nine endpoints: authenticate, search, details, fare-brands, change-options, create order, issue, order status and cancel-hold.
  • A compact offer object: flat price, journeys and segments, IATA codes, local date-times, and price breakdown and baggage limited to the passenger types searched.
  • A dictionaries block with carrier and airport names on search, details and change-options.
  • Two-step purchase: create order (nothing booked or paid), then issue, which books the seats, charges the wallet and tickets in one call.
  • Fare families where the airline sells them, applied by brand code.
  • On-hold bookings with holdOnly, an explicit hold deadline, and release with cancel-hold.
  • Payment from the agency wallet in USD.
Not yet included: multi-destination itineraries, fare rules (refund and change conditions), cancellation, refund and void of issued tickets, and passenger changes.
