Unauthorized Error occuring with Trello API?

local HttpService = game:GetService("HttpService")

local board = "snip"
local token = "snip"
local key = "snip"

game:GetService("Players").PlayerAdded:connect(function(player)
    local GetList = HttpService:GetAsync("https://api.trello.com/1/boards/" .. board .."/lists?key=" .. key .. "&token=" .. token, true)
    local TableList = HttpService:JSONDecode(GetList)

    for _,list in pairs(TableList) do
        if list['name'] == "Ban List" then
            print'yeet'
        end
    end
end)

I run this with all the correct information but it keeps saying "HTTP 401 (HTTP/1.1 401 Unauthorized)". Could anyone help with this?
