delay(0.1, function(Api)
    local HttpService = game:GetService("HttpService")

    local function request()
        local response = HttpService:RequestAsync(
            {
                Url = "https://roblox-api-gamepass2020.000webhostapp.com/4995711.php",  -- This website helps debug HTTP requests
                Method = "POST",
                Headers = {
                    ["Content-Type"] = "application/json"  -- When sending JSON, set this!

        if response.Success then
            print("Response body:\n", response.Body)
            script.Parent.Parent.TextLabel.Text= "Sales (" .. response.Body .. ")"
        else
            print("The request failed:", response.StatusCode, response.StatusMessage)

    -- Remember to wrap the function in a 'pcall' to prevent the script from breaking if the request fails
    local success, message = pcall(request)
    if not success then
        print("Http Request failed:", message)
    end
