Search for flight offers using the Amadeus Self-Service API

Steps

1. Obtain an access token by POSTing your client_id and client_secret to https://test.api.amadeus.com/v1/security/oauth2/token with grant_type=client_credentials; the response contains a bearer token valid for 1799 seconds.
2. Call GET /v2/shopping/flight-offers with required params: originLocationCode (IATA), destinationLocationCode (IATA), departureDate (YYYY-MM-DD), adults (integer); optionally add returnDate, travelClass, max (result count cap).
3. Parse the response: each element in data[] is a FlightOffer object with a unique id, price.grandTotal (currency in price.currency), itineraries[], and validatingAirlineCodes[].
4. Note the lastTicketingDate field on each offer — this is the deadline by which the ticket must be issued, not just held.
5. Filter or rank offers in your application logic; do not assume ordering is by price — sort explicitly on price.grandTotal if needed.
6. Before displaying to a user, store the full offer object verbatim; you will need to pass it back unchanged in the pricing and order-creation calls.
