Wanting to know the most appropriate way to export in game data to the webserver (HTML5 build)

I’m building a simple UE4 game, having said that, I have a requirement to export collected bits of information/stats in-game, to the game server (the game will be a HTML5 build). I am aware there is a JSON Query plugin, that may do the job, and currently I am trying to do this using an external bluprint function, and a mod to the HTML file to call that function (but getting nowhere fast). Are there any better ways of doing this…? Are there any standard methods that developers use to do this…?? Am I on the right or wrong track ??

Please be advised I am a newb to UE4, be gentle please…Many thanks in advance…!!
