Expedia Flights API

Expedia Group publishes a Rapid Flight API for flight shopping, booking, and managing bookings. Access starts with becoming an Expedia Group partner and obtaining approval and credentials. Public documentation alone does not provide production access.

If you need to search flight fares and send users to booking pages, Ignav covers that smaller scope and is easier to start with. It does not give you Expedia inventory or a full Expedia booking stack.

What developers are usually trying to build

Expedia API searches usually come from teams building a travel portal, loyalty product, package flow, internal travel tool, or comparison page. For flights, you often need less: show current route prices, filter itineraries, and send the traveler to a place where the fare can be booked.

Using Ignav for the flight piece

Ignav covers the fare-search and booking-link portion with five endpoints: one-way fares, round-trip fares, flexible search, booking links, and airport search. Fare results include prices, carriers, segments, baggage fields, and an ignav_id. Booking-link lookups return airline and OTA URLs for the chosen itinerary.

Access is self-serve after email verification. You get 1,000 free requests, then pay $2.00 per 1,000 successful requests. Failed requests are not billed, and authenticated API use has no per-account rate limit.

What Ignav does not cover

Ignav does not replace Expedia Rapid, lodging APIs, package booking, payments, post-booking service, or Expedia partner economics. It also does not sell flights, issue tickets, manage orders, or handle traveler changes. Use it when link-out is enough.
