Help and Feedback Scripting Support
#1

Hi,
I wrote a script which would detect when player purchase a thing but events MarketplaceService.PromptGamePassPurchaseFinished and MarketplaceService.PromptPurchaseFinished are not working I checked by printing

Script in ServerScriptService

local MarketplaceService = game:GetService("MarketplaceService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")

local ShowPurchaseCompletedScreen = ReplicatedStorage:WaitForChild('ShowPurchaseCompletedScreen')

MarketplaceService.PromptGamePassPurchaseFinished:Connect(function(player: Instance, assetId: number, isPurchased: boolean)
	if isPurchased then
		local ProductInfo = MarketplaceService:GetProductInfo()
		if player:GetAttribute("RobuxSpent") then
			player:SetAttribute("RobuxSpent", player:GetAttribute("RobuxSpent") + ProductInfo.PriceInRobux)
		end
		
		ShowPurchaseCompletedScreen:FireClient(player, assetId)
	end
end)

MarketplaceService.PromptPurchaseFinished:Connect(function(player: Instance, assetId: number, isPurchased: boolean)
	if isPurchased then
		local ProductInfo = MarketplaceService:GetProductInfo()
		if player:GetAttribute("RobuxSpent") then
			player:SetAttribute("RobuxSpent", player:GetAttribute("RobuxSpent") + ProductInfo.PriceInRobux)
		end

		ShowPurchaseCompletedScreen:FireClient(player, assetId)
	end
end)
