Activity Logging connected to an API

[tepid lagoon]

After creating the code, it still doesn't work even though the url and API are correct, can you help me to turn it around somehow?

local Timers = {}
Players.PlayerAdded:Connect(function(Player)
    Timers[Player.UserId] = {
        Start = os.time()
    }
end)

Players.PlayerRemoving:Connect(function(Player)
    Timers[Player.UserId].End = os.time()

    local TotalTime = Timers[Player.UserId].End - Timers[Player.UserId].Start
    
end)

local HttpService = game:GetService("HttpService")

local BASE_URL = "url"
local API_KEY = "1234567890"

local function sendMessage(message)
    local url = string.format("%s", BASE_URL, message)
    local headers = {["X-API-Key"] = API_KEY}
    local success, response = pcall(function()
        return HttpService:PostAsync(url, "", Enum.HttpContentType.ApplicationJson, false, headers)
    end)
    if success then
        local result = HttpService:JSONDecode(response)
        if result.success then
            print(result)
            
        else
            warn("API Error:", result.error or "Unknown error")
        end
    else
        warn("Request failed:", response)
    end
end

str(TotalTime)```

I don't understand how to fix it, but whatever I try it doesn't respond or it tells me Error 400 (Bad Request)

RequestAsync requires a few more parameters, but it allows you to get the response message so you can get an actual reason it's giving you the 400 error

How can I turn it?

Fix

https://create.roblox.com/docs/reference/engine/classes/HttpService#RequestAsync

you give this function a dictionary containing similar stuff to what you put directly into the PostAsync

Thanks, I set this as Solved.

This won't magically fix it, but it will give you more in the response so you can see the actual issue
