Product Purchase Finish Not Working

Help and Feedback Scripting Support

#1

Hello and good evening developers,

I am currently working on a script that prompts the player with my developer product for a sword. When it is done, it is supposed to check if the purchase was a success and if so, give the player the sword. The player is prompted with the developer product purchase, but the function does not work to check. Nothing happens when I cancel and when I purchase. Any help is appreciated. Thanks!

Script:

--D00MED_S0ULL
local plr = game.Players.LocalPlayer
local Click = game.StarterGui.GUIClick
local gamepassId = 1207843619 -- All you have to do is change this to the right gamepass
local PromptCashPurchase = game.ReplicatedStorage.PromptCashPurhcase
local MarketplaceService = game:GetService("MarketplaceService")
local Sword = game.ReplicatedStorage.Tools.AzureSword

script.Parent.MouseButton1Click:Connect(function()
	Click:Play()
	MarketplaceService:PromptProductPurchase(plr, gamepassId)
	MarketplaceService.PromptPurchaseFinished:Connect(function(player, assetId, success)
		if success then
			if assetId == gamepassId then
				local Clone = Sword:Clone()
				Clone.Parent = player:WaitForChild("Backpack")
			end
		end
	end)
end)

Success returns a bool value so you would check if its true or false:

local plr = game.Players.LocalPlayer
local Click = game.StarterGui.GUIClick
local gamepassId = 1207843619
local PromptCashPurchase = game.ReplicatedStorage.PromptCashPurhcase
local MarketplaceService = game:GetService("MarketplaceService")
local Sword = game.ReplicatedStorage.Tools.AzureSword

script.Parent.MouseButton1Click:Connect(function()
	Click:Play()
	MarketplaceService:PromptProductPurchase(plr, gamepassId)
	MarketplaceService.PromptPurchaseFinished:Connect(function(player, assetId, success)
		if success == true then
			if assetId == gamepassId then
				local Clone = Sword:Clone()
				Clone.Parent = player:WaitForChild("Backpack")
			end
		end
	end)
end)

Doesn’t “if success then” imply a check for true automatically?

#4

This didn’t work. Like I said below, true is already implied.

#5

Second thought, assetIds and gamepassIds aren’t the same thing, so it should work if you remove the check.

#6

So just the first two parameters?

#7

Yes.

if success then
local Clone = Sword:Clone()
Clone.Parent = player:WaitForChild("Backpack")
end
#8

You just said get rid of success. Can you revise this into my script please?

As it is a developer product, you must use ProcessReceipt as this tutorial indicates.

local script 
local plr = game:GetService("Players").LocalPlayer
local Click = game:GetService("StarterGui").GUIClick

script.Parent.MouseButton1Click:Connect(function()
	Click:Play()
	game:GetService("MarketplaceService"):PromptProductPurchase(plr, 1207843619)
end)
script must be in ServerScriptService. 
local PromptCashPurchase = game:GetService("ReplicatedStorage").PromptCashPurhcase
local Sword = game:GetService("ReplicatedStorage").Tools.AzureSword

local Functions = {}
Functions[1207843619] = function(receiptInfo)
	local Player = game:GetService("Players"):GetPlayerByUserId(receiptInfo.PlayerId)
	if not Player then		return 		end
	Sword:Clone().Parent = Player:WaitForChild("Backpack")
	return true
end

game:GetService("MarketplaceService").ProcessReceipt = function(receiptInfo)
	local Product = receiptInfo.ProductId
	
	local Success, Completed = pcall(Functions[Product], receiptInfo)
	if not Success or not Completed then
		warn("Error:", Completed)
		return Enum.ProductPurchaseDecision.NotProcessedYet
	end
	
	return Enum.ProductPurchaseDecision.PurchaseGranted
end

keep in mind if you add more products, they should all be as in table Functions and it should be like this

Functions[Id] = function(receiptInfo)
	-- code
end)

if you have multiple accessing ProcessReceipt it may not work
