How do I send data from a game to a server?

Hi all. I did a quick search for this, but I wasn't sure what keywords to focus on, so I thought I would open up my question to the community.

I would like to make a collection of minigames which, when completed, would send the scores to a server, which would then be added to the players 'account'. Perhaps something like an XBox Live account tied to a Facebook account, if that makes any sense.

I have no idea where to start with this one.

1. What's the best way to handle this on the Construct side? I was thinking that the stats and scores could be held on a JSON array and then, when the play exits, the array is send to the website/server. How might y'all handle doing something like this?

2. What's the best way to handle this on the server side? I am a complete noobie. I barely know how to use construct. I'm looking for something cheap and easy. Something on which the players can make an account/profile, play html games on that website, and then the score data from the game would be logged on their account.

Thanks all! 😊✌️
