In-game purchased gamepasses not giving rewards

Help and Feedback Scripting Support
#1

After receiving the prompt, I click Buy and I am able to buy the gamepass but I do not receive the reward/ability after that. I followed the wiki so I am not sure what is wrong, its not printing that I have purchased the gamepass.

Server Code:

local MarketplaceService = game:GetService("MarketplaceService")
 
local gamePassID = 4576507
 
-- Function to handle a completed prompt and purchase
local function onPromptGamePassPurchaseFinished(player, purchasedPassID, purchaseSuccess)
 
    if purchaseSuccess == true and purchasedPassID == gamePassID then
        print(player.Name .. " purchased the game pass with ID " .. gamePassID)

player.CharacterAdded:connect(function(character)
character.Humanoid.WalkSpeed = 32
end)

    end
end
 
-- Connect 'PromptGamePassPurchaseFinished' events to the 'onPromptGamePassPurchaseFinished()' function
MarketplaceService.PromptGamePassPurchaseFinished:Connect(onPromptGamePassPurchaseFinished)

thanks

Client is working fine but here is the code if you want

local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")
 
local gamePassID = 4576507
local gui = script.Parent
-- Function to prompt purchase of the game pass
local function promptPurchase()
 
    local player = Players.LocalPlayer
    local hasPass = false
 
    local success, message = pcall(function()
        hasPass = MarketplaceService:UserOwnsGamePassAsync(player.UserId, gamePassID)
    end)
 
    if not success then
        warn("Error while checking if player has pass: " .. tostring(message))
        return
    end
 
    if hasPass == true then
        print(player.Name.." already has gamepass")
    else
        -- Player does NOT own the game pass; prompt them to purchase
        MarketplaceService:PromptGamePassPurchase(player, gamePassID)
    end
end


gui.MouseEnter:connect(function()
    gui.ImageColor3 = Color3.fromRGB(83, 203, 83)
end)

gui.MouseLeave:connect(function()
    gui.ImageColor3 = Color3.fromRGB(102, 255, 102)
end)

gui.MouseButton1Click:connect(function()

promptPurchase()
end)

I’ve got no problems with it printing that the game pass was purchased, I’m not sure how/if that is happening. But these are 2 possible problems I’ve noticed:

  • When the player purchases the item, their walk speed will only change after resetting because the only place you change it is within the CharacterAdded event.
  • In the CharacterAdded event, you index the Humanoid immediately. I believe that it is not always accessible immediately after the character is added, use :WaitForChild() to be safe.

Addressing these issues results in this code:

local MarketplaceService = game:GetService("MarketplaceService")
 
local gamePassID = 4576507

-- Function to handle a completed prompt and purchase
local function onPromptGamePassPurchaseFinished(player, purchasedPassID, purchaseSuccess)
	if purchaseSuccess == true and purchasedPassID == gamePassID then
		print(player.Name .. " purchased the game pass with ID " .. gamePassID)
		player.CharacterAdded:connect(function(character)
			character:WaitForChild("Humanoid").WalkSpeed = 32
		end)
		if player.Character then
			player.Character:WaitForChild("Humanoid").WalkSpeed = 32
		end
	end
end

-- Connect 'PromptGamePassPurchaseFinished' events to the 'onPromptGamePassPurchaseFinished()' function
MarketplaceService.PromptGamePassPurchaseFinished:Connect(onPromptGamePassPurchaseFinished)

But it’s not printing that I bought it, also tested your code and it still does not work

Are you getting any errors? Have you tried, temporarily, using another purchase function? Do you have the right GamePassId?

There could be small errors you’re overlooking which are leading to the failure of your code.

The IDs are correct, I used the same ID in the gamepass prompt purchase
