I got the API key (Access Permissions FlightXML Versions: v3) My call “[http://semgep:myAPIkey@flightxml.flightaware.com/json/FlightXML2/FlightInfoEx?ident=AAL174&howMany=25&offset=0](http://semgep:myAPIkey@flightxml.flightaware.com/json/FlightXML2/FlightInfoEx?ident=AAL174&howMany=25&offset=0)” Response: 401 Authentication Required! Where is my problem ? ---

FlightXML actually uses “user name / password” authentication, so you need to use this kind of code: ```auto username = "funkmeister380" apiKey = "xxx" fxmlUrl = "https://flightxml.flightaware.com/json/FlightXML3/" response = requests.get(fxmlUrl + command, params=payload, auth=(username, apiKey)) ``` ---

Thanks! I build an application for Аndroid. Now, on your recommendation, I’m using a call “[https://flightxml.flightaware.com/json/FlightXML3/FlightInfoEx?ident=AAL174&howMany=25&offset=0&auth=(semgep,myAPIkey)](https://flightxml.flightaware.com/json/FlightXML3/FlightInfoEx?ident=AAL174&howMany=25&offset=0&auth=(semgep,myAPIkey))” and again get “Authentication Required”! Perhaps I incorrectly included the username and APIkey in the URL? How to do it in Android (Java) ? ---

You may have to encode the authentication string – base64 if I remember correctly. Google is your friend 🙂 ---

In version 3, there are much fewer functions than in version 2 - for example, there is no FlightInfoEx function. Is it planned to expand the feature set in version 3? What changes are there in version 3? ---

V3 is an incomplete beta product and they’re not offering specifics for when the full feature-set might be available; from what I’ve seen, what is available in V3 is pretty solid, but, you’ll likely need a combination of V2 and V3 at least for the next several months. ---

I got the API key (Access Permissions FlightXML Versions: v3). When I call V2, I get a message “Authentication Required”. What solution to this problem? ---

You must use a separate API key for v2 than your key for v3. You may request another v2 key from [AeroAPI Key Generation - FlightAware](https://flightaware.com/commercial/flightxml/key) ---

You would need a FlightXML 2 key. You can get one at the following link. [https://flightaware.com/commercial/flightxml/key](https://flightaware.com/commercial/flightxml/key). There should be a link to get the V2 key. ---

No, there isn’t, All I see is button to “Add new FlightXML 3 Key” ---

use v3 - you can chain calls to get the required data. this also conforms much better to a programming paradigm. ---

Not true: below that button is a line and link that reads “you can still **request another FlightXML2 key to be added** to your account.” ---

Maybe its changed, or different just for me, Please see the attached screenshot. ![Screenshot at Jan 11 16-29-36](https://us1.discourse-cdn.com/flex019/uploads/flightaware/original/2X/a/a744e68400f086235920c49dd30e0b47a5bcf07d.jpg) ---

As indicated at the bottom, your billing information needs updating before you’ll have the ability add another FlightXML2 key by yourself.
