A naive script might do this:
Open your ShopServerScript (inside ServerScriptService). This script securely processes the transaction.
By mastering the relationship between LocalScripts and RemoteEvents, you can build complex, secure, and professional interfaces that thrive in the Roblox ecosystem. Intro to GUI - Roblox GUI Tutorial #1 roblox fe gui script
If you want a GUI to show a global countdown, the Server shouldn't try to edit the player's PlayerGui directly. Instead, use a StringValue in ReplicatedStorage and have the LocalScript watch for changes to update its own text.
This script listens for the request from the client. It validates whether the player is actually allowed to perform that action (e.g., checking if they have enough in-game currency) and then executes the change globally. Step-by-Step Tutorial: Creating a Secure Shop GUI
What is your GUI trying to accomplish (shop system, admin panel, stat tracker)? Do you need to pass complex data from the UI to the server? Share public link local remote = Instance
Handles the "truth" of the game (leaderboards, health, inventory).
This public link is valid for 7 days and shares a thread, including any personal information you added. This link or copies made by others cannot be deleted. If you share with third parties, their policies apply. Can’t copy the link right now. Try again later.
In a proper FE system, an "ESP" (Extra-Sensory Perception) script that shows players through walls usually only works for the user running the script. However, more advanced systems can make an ESP feature visible to a team or all players. This is achieved by the GUI, sending a request to the server to create a BillboardGui or highlight effect on a target player, which is then visible to all clients [16†L11-L14]. This script listens for the request from the client
First, open Roblox Studio and find StarterGui in the Explorer. This is where you place GUIs that will appear for every player when they join the game. Create a ScreenGui and then add a TextButton inside it.

Crucial Security Best Practices
The core irony of FE-based exploits is that they don't break FE; they obey it. Instead of directly changing server health, they manipulate what the server trusts from the client. A classic example is the "FE Gun Script":
This article provides an in-depth look at what FE GUI scripts are, how they work, how to create them, and the ethical considerations surrounding their use. 1. What is FE (FilteringEnabled) in Roblox?
