Is there a way to Change from ICAO TO IATA Airport Code? Api

Is there a way to get the return airport in IATA(International Air Transport Association ) Airport code instead of getting it in ICAO(International Civil Aviation Organization)?. Example for this is instead of getting KATL, i want to show it as ATL.

Airport IATA, when available, is exposed in FlightXML 3 as the alternate_ident when using AirportInfo or any API call that includes AirportStruct as part of the returned data.

If using FlightXML 2 this conversion will need to be handled in your application.
