I've been coding for a while and I've never touched HTTPService. I was looking to see if it was possible to make HTTP Requests to Roblox and check how many players are playing certain games.

I found a website which shows most of the HTTP documentation, but I don't know how to go about implementing it.

https://api.roblox.com/docs?useConsolidatedPage=true

It appears that there are tons of things you can do and I would love to explore them and see what is possible. I just don't even know where to start.

If anyone has some spare time to explain to me how this all works I would greatly appreciate it :)

I was messing around and this is about all I can get... It errors with "Trust Check Failed"

local HTTPService = game:GetService("HttpService")

local Success, Error = pcall(function()
	local Data = HTTPService:JSONDecode(HTTPService:GetAsync("http://roblox.com/v1/games/multiget-place-details"))
end)

print(Success, Error)
