I have a FME Server web workspace converting a file from SHP to KML, once it runs it outputs a kml file, I need to be able to take this file and drop into my web API google Map. Is there a way to retrieve this temporary file and display in my web map?
Yes with Data Streaming the KML - See 'Stream KML Google Maps'
[fmeserver.com/userweb/sharper/playground/index.html] var ctaLayer = new google.maps.KmlLayer('http://fmeserver.com:80/fmedatastreaming/Samples/austinApartments.fmw?');
is doing the request on the page request (on first load or refresh)
FME Server is running the workspace and delivering the KML back to the map and the KML is drawn on top of the Google Map.
