Custom in-game key UI

On your script’s Delivery page, download Key System and edit its Roblox GUI layout, colors, and text. Keep its key submission code intact. For a UI you build from scratch, connect your key button to the public loader as shown below. Replace only YOUR_SCRIPT_ID with the script ID from your dashboard. Point a “Get key” button to your public /gateway/YOUR_SLUG page.

-- Call this from your own key-entry button after reading its TextBox.
local SCRIPT_ID = "YOUR_SCRIPT_ID"
local busy = false

local function submitKey(key)
    if busy then return false end
    key = tostring(key or ""):match("^%s*(.-)%s*$")
    if key == "" then return false end
    busy = true

    local env = (getgenv and getgenv()) or _G
    env.Key = key
    local ok = pcall(function()
        loadstring(game:HttpGet(
            "https://api.nullauth.pro/api/v1/loader/" .. SCRIPT_ID
        ))()
    end)

    busy = false
    return ok
end

-- Example: loadButton.MouseButton1Click:Connect(function()
--     submitKey(keyBox.Text)
-- end)

The script ID and loader URL are public. The entered key is supplied at runtime. Never publish a real customer key, Linkvertise token, API credential, signing secret, build ticket, session token, or protected script source in your UI or documentation. Authorization and ticket checks stay on Null’s server. Any Lua code delivered to a player can be inspected, so a custom UI is presentation, not a secret store.
