We have a good tutorial by @cam regarding web hooks: Tutorial - How to send a message from Roblox to Discord (webhooks) - Tutorial - Cookie Tech (thecookie.dev)

Something like this should work:

local HttpService = game:GetService("HttpService")
local ReplicatedStorage = game.ReplicatedStorage
local AppUrl = script.AppUrl.Value
local ApiKey = script.ApiKey.Value
local Groupid = script.GroupId.Value
local MinRank = script.MinRank.Value
local prefix = "!"
local WebhookUrl = ""


local function UpdateStatus(status, user)
if status == true then
     local data = {
     ['content'] = user.." got promoted!"}
   httpService:PostAsync(webhookUrl,httpService:JSONEncode(data))
else
        local data = {
     ['content'] = user.." got demoted!"}
   httpService:PostAsync(webhookUrl,httpService:JSONEncode(data))
end


local function FindPlr(plr)
	local foundPlr = nil
	local plrs = game.Players:GetPlayers()
	for i = 1, #plrs do
		local current = plrs[i]
		if string.lower(current.Name):sub(1, #plr) == string.lower(plr) then
			foundPlr = current.Name
			break
		end
	end
	return foundPlr
end


game.Players.PlayerAdded:Connect(function(player)
	player.Chatted:Connect(function(msg)
		if player:GetRankInGroup(Groupid) >= 254 then
			local LowerCaseMessage = string.lower(msg)
			if string.find(LowerCaseMessage, "!promote") then
				local SplitMessage = string.split(msg, " ")
				local full_player = FindPlr(SplitMessage[2])
				if full_player == nil then
					local playerInstance = game.Players:FindFirstChild(player.Name)
					game.ReplicatedStorage.Notify:FireClient(playerInstance, "Error!","We couldn't find the player you wanted to promote!")
				else
					local playerInstance = game.Players:FindFirstChild(player.Name)
					local Url = script.AppUrl.Value.."group/promote?user_name="..full_player.."&key=" ..script.ApiKey.Value.."&groupid="..script.GroupId.Value
					local success, response = pcall(function()
						local response = HttpService:GetAsync(Url)
						local data = HttpService:JSONDecode(response)
					end)
					if success then
                                         UpdateStatus(true, playerInstance )
						game.ReplicatedStorage.Notify:FireClient(playerInstance, "Success!","User has been promoted!")
					else
						game.ReplicatedStorage.Notify:FireClient(playerInstance, "Error!","We ran into some problems.")
					end
				end
			else if string.find(LowerCaseMessage, "!demote") then
					local SplitMessage = string.split(msg, " ")
					local full_player = FindPlr(SplitMessage[2])
					if full_player == nil then
						local playerInstance = game.Players:FindFirstChild(player.Name)
						game.ReplicatedStorage.Notify:FireClient(playerInstance, "Error!","We couldn't find the player you wanted to demote!")
					else
						local playerInstance = game.Players:FindFirstChild(player.Name)
						local Url = script.AppUrl.Value.."group/demote?user_name="..full_player.. "&key=" ..script.ApiKey.Value.. "&groupid=" ..script.GroupId.Value
						local success, response = pcall(function()
							local response = HttpService:GetAsync(Url)
							local data = HttpService:JSONDecode(response)
						end)
						if success then
                                                  UpdateStatus(false, playerInstance )
							game.ReplicatedStorage.Notify:FireClient(playerInstance, "Success!","User has been demoted!")
						else
							game.ReplicatedStorage.Notify:FireClient(playerInstance, "Error!","We ran into some problems.")
						end
					end
				end
			end
		end
	end)
