Breeze Airways NDC Gateway
The Breeze Airways NDC gateway is the airline's direct-connect distribution API for accredited travel partners. It speaks IATA Offers and Orders (NDC) 21.3 XML over HTTPS on a Navitaire-hosted gateway, split into three route families: Shopping (AirlineProfile, AirShopping), Selling (Auth, OfferPrice, ServiceList, SeatAvailability, OrderCreate) and Servicing (OrderRetrieve, OrderQuote, OrderReshop, OrderChange, ServiceList, SeatAvailability). Every request carries an Ocp-Apim-Subscription-Key header; all routes except AirShopping additionally require a session bearer token obtained from the Auth endpoint with grant_type=client_credentials. Calling IPs must be explicitly allowlisted by Breeze for the sandbox or production environment.
