How to get airport data

For a while now chrome no longer supports sending user/pass in the AJAX etc so I am looking into altarnatives.
The next best for my use is the XML3 php rest/curl method. As seen here: flightxml3_examples/php/rest/curl at master · flightaware/flightxml3_examples · GitHub

Has any one been able to get this to work with AirportBoards V3? I have had no luck.
Any help is appreciated thanks.
