Amadeus City and Airports Location API AutoComplete System

Question

I am adding the AutoComplete System to a booking website that I am developing. I understand that the autoComplete system fetches from a pre-populated data.So I am trying to locations/airport codes from https://test.api.amadeus.com/v1/reference-data/locations to view the list of all locations so that I can design the auto-complete system but I get a bad response, my application is missing an important parameter.I am trying to display a list of locations. I hope someone can point out where I have gone wrong.

"use_strict";
function getLocations(){
 let url = "https://test.api.amadeus.com/v1/reference-data/locations";  
 fetch(url,{
     method:"GET",
     headers:{
         "Content-Type":"application/json",
         "Authorization":"Bearer BgRWNa48WGmqPowlRCMvIwHt6a96"
     },
     mode:"cors",
     catch:"default"
 }).then(function(response){
         return response.json();
 }).then(function(data){
     console.log(data);
 }).catch(function(error){
     console.log(error);
 });
}

getLocations();

Answer 1

You are missing the mandatory query parameters. According to the API reference, subType (AIRPORT or CITY) and keyword parameters are needed. For example:

https://test.api.amadeus.com/v1/reference-data/locations?subType=AIRPORT&keyword=LON

will return a list of airports whose name contains the keyword LON (London Heathrow, London Gatwick, London Stansted, etc.)
