[SOLVED]How do I make a post to discord using HTTPServices?

I am trying to make a script that posts on a discord Channel saying a new item has been added to the game, but I don't know how I would do this, I tried something like the script below, but it didn't work.

local hs = game:GetService("HttpService")
--Posting
local Text = "A new item has been added!"
hs:PostAsync("https://discordapp.com/channels/479495934166827025/479496644703027211",Text)
