Inside of the purchase gui:



local buyButton = script.Parent
local productId = 20308410

buyButton.MouseButton1Click:connect(function()
	game:GetService("MarketplaceService"):PromptProductPurchase(game.Players.LocalPlayer, productId)
end)



Inside of the tool that is supposed to be awarded:



local MarketplaceService = Game:GetService("MarketplaceService")
local ds = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")
local productId = 20308410

MarketplaceService.ProcessReceipt = function(receiptInfo)


	for i, player in ipairs(game.Players:GetChildren()) do
		if player.userId == receiptInfo.PlayerId then



			if receiptInfo.ProductId == productId then


				local mk = game.Lighting.Medkit:clone()
				mk.Parent = player.StarterGear
				local h = Instance.new("Hint", game.Workspace)
				h.Text = player.Name .. " has purchased an item, creating more player points!"
			end
		end
	end

	local playerProductKey = "player_" .. receiptInfo.PlayerId .. "_purchase_" .. receiptInfo.PurchaseId
	ds:IncrementAsync(playerProductKey, 1)

	return Enum.ProductPurchaseDecision.PurchaseGranted
end
