# :StopListening

Stops listening for updates for a specific `realKey`. This informs the server to stop sending updates for this key to this client and cleans up all local resources (cache entry and signals) associated with it.

It's a crucial practice to call this when a piece of UI is destroyed or a system no longer needs the data to prevent memory leaks and unnecessary network traffic.

**`DataReplicator:StopListening(realKey: string)`**

```lua
local scoreboardFrame = script.Parent
local TEAM_SCORE_KEY = "Public_TeamScore_Blue"

-- Start listening when the scoreboard is created.
local teamScoreSignal = DataReplicator:Listen(TEAM_SCORE_KEY)
local connection = teamScoreSignal:Connect(function(score)
	-- ... update UI ...
end)

-- When the scoreboard is destroyed, stop listening to free up resources.
scoreboardFrame.Destroying:Connect(function()
	connection:Disconnect()
	DataReplicator:StopListening(TEAM_SCORE_KEY)
	print("Stopped listening to team score updates.")
end)
