What is NDC and why do I need an aggregator?

NDC (New Distribution Capability) is IATA's XML messaging standard for selling airline products. Every airline implements it differently. An aggregator gives you one integration that handles all those quirks.

How does pricing work?

You pay per request for data lookups (€0.01/request, first 50 free each month) and transaction fees when bookings, seats, or ancillaries are completed.

Servicing endpoints in development

The Servicing API endpoints are currently under active development. Request/response shapes may change.

Servicing

Assign seats

Pick seats for passengers after booking — update anytime before departure.

POST/v1/orders/{orderID}/seatsRequires X-API-Key

Assign or change seats for passengers on specific flight segments. This is the post-booking equivalent of the pre-booking seat map.Use cases:
- Traveler wants to choose seats after booking
- Traveler wants to change a previously selected seat
- Assign seats for multiple passengers at onceEach assignment pairs a seat_id (from the seat map) with a passenger_id. The response returns the updated order with all assigned seats.Timing: Most airlines allow seat changes up until online check-in closes (typically 2–24 hours before departure). Some airlines charge a change fee for seat modifications after the initial selection.
