Re: How to work with Amadeus ?

That's great, it works perfectly (I used my access rights, API Key & API
Secret). Thank you very much.

I got reply from Amadeus (strings altered for posting here ;-)):

...
< Server: Amadeus
<
* Connection #0 to host test.api.amadeus.com left intact

         {
             "type": "amadeusOAuth2Token",
             "username": "name_at_xxx.com",
             "application_name": "Test",
             "client_id": "xF1ywe4wwzDg3aFVAq19WecrgA3jthKx",
             "token_type": "Bearer",
             "access_token": "VLHdm2tTNf6ojlg7J2ZLla5pACNa",
             "expires_in": 1799,
             "state": "approved",
             "scope": ""
         }

Next step is how to parse "access_token" and store its value into
variable for further use (Amadeus API calls).
See description here, Step 4: Make your first call:
https://developers.amadeus.com/get-started/get-started-with-self-service-apis-335

Than how to continue with received token to send the first API inquiry
to Amadeus ?

curl -X GET
'https://test.api.amadeus.com/v1/shopping/flight-destinations?origin=PAR&maxPrice=200'
-H 'Authorization: Bearer {{token}}'

--dr
