Couple questions I have about Trello and its usages?

Ok. So I am trying to make a trello system that creates a card when you like get 1000 points in a game. But I am fairly new to Trello and I haven't found any good tutorials that actually tell me how to connect it to the website.

local HttpService = game:GetService("HttpService")

local API 	= "https://trello.com/b/8DigitCode"
local Token = "ThisWasAVeryLongToken"

local T= {}

HttpService.HttpEnabled = true;

function T(x, y, z)
	
	local Data			= {
		Name 			= x;
		Description 	= y;
		IdList 			= z;
		URLSource		= nil;
	}
	
	HttpService:PostAsync(API .. Token, HttpService:JSONEncode(Data)) -- Is the Api .. Token the right thing to do? Idk how to link it there. 
end;

local function PlayerAdd (LocalPlayer) 
	local Folder = LocalPlayer:WaitForChild("leaderstats")
	local Level = Folder.Level
	
	if Level.Value == 1000 then 
		CreateCard(LocalPlayer.Name, "Got 1000 points", Token) -- Token here again?
	end	
end

game.Players.PlayerAdded:Connect(PlayerAdd)

What I am trying to do, (BUT NO IDEA HOW TO DO AND WHAT I AM DOING), is when a player achieves 100 points, it is going to create a card. The title would be the rank and inside would be the some other informations such as who got it.

If someone could tell me what "Token" is and what are some other things I am missing, it would be great!

Sorry if this does not meet the criteria or if this is a really dumb question in general. I hope you are still able to help me out!

Also, is there like a good tutorial for using Trello? All I found in youtube is the freemodels that only require you to write like arguments and stuff. I want to make my own.
