Please always double-check snippets, that RapidAPI is generating for you. They are not always correct. In particular, they encode colon symbols in the URL, although this should not happen in fragment part of the URL. E.g.: https://aerodatabox.p.rapidapi.com/flights/airports/icao/KSFO/2019-09-16T06%3A00/2019-09-16T12%3A00 should be https://aerodatabox.p.rapidapi.com/flights/airports/icao/KSFO/2019-09-16T06:00/2019-09-16T12:00 You also should not follow wrong snippet example: don’t encode time in the request.

Hello everybody.

I confirm that I have the same problem.

The API call “Departures and arrivals (FIDS) by airport ICAO code” works here:
https://rapidapi.com/squawk7000/api/aerodatabox

but it does not work in my web application.

The other calls also work in my interface. I tried the javascript solution (both with fetch and the others).

Hello! It may be that RapidAPI generates a faulty code snipped for you. Could you please specify which endpoint is causing the issue?
