I made a donate button and my friend tested it out. He payed and lost the robux but nothing shoed up in my account. It has been 17 hours, here is the code I am using:

1MPS = game:GetService("MarketplaceService")
2id = 1138688305
3local player = game.Players.LocalPlayer
4 
5script.Parent.MouseButton1Click:Connect(function()
6    MPS:PromptProductPurchase(player, id)
7end)

Why are you doing this on the client? This is the most ineffective way to get any user a gamepass, or an item for that matter. Prompt the purchase on the server. DeceptiveCaster 3761 — 4y

erm mate, you did not get the robux you mean? Read this article, you need to wait 3-7 days: https://devforum.roblox.com/t/incoming-adjustment-to-pending-sales-waiting-period/832724 imKirda 4491 — 4y

i see your script. if youre using a gamepass:

1local productId = 1138688305
2game.Players.PlayerAdded:Connect(function(player)
3    Game:GetService("MarketplaceService"):PromptProductPurchase(player, productId)
4end)

if its a devproduct:

01local MarketplaceService = game:GetService("MarketplaceService")
02local Players = game:GetService("Players")
03 
04local productID =  1138688305 -- Change this to your developer product ID
05 
06-- Function to prompt purchase of the developer product
07local function promptPurchase()
08    local player = Players.LocalPlayer
09    MarketplaceService:PromptProductPurchase(player, productID)
10end

after that you need to insert another script in serverscriptservice if youre using a devproduct to get the robux... you forgot that. but you have to add a benifit for that donation. how about 1 gold(lol)?

01local MarketplaceService = game:GetService("MarketplaceService")
02local DataStoreService = game:GetService("DataStoreService")
03local Players = game:GetService("Players")
04 
05-- Data store for tracking purchases that were successfully processed
06local purchaseHistoryStore = DataStoreService:GetDataStore("PurchaseHistory")
07 
08-- Table setup containing product IDs and functions for handling purchases
09local productFunctions = {}
10-- ProductId 1138688305 for 
11productFunctions[1138688305] = function(receipt, player)
12    --we do this because there has to be some benefit in a devproduct.
13    local stats = player:FindFirstChild("leaderstats")
14    local gold = stats and stats:FindFirstChild("Gold")
15    if gold then
16        gold.Value = gold.Value + 1
17        -- Indicate a successful purchase
18        return true
19    end
20end
21 --------------------------------------------------------------------------------------------------------------------------
22--DO NOT TOUCH THIS SCRIPT FROM NOW ON OR ELSE YOU WILL NOT GET ROBUX!!!
23-- The core 'ProcessReceipt' callback function
24local function processReceipt(receiptInfo)
25 
26    -- Determine if the product was already granted by checking the data store  
27    local playerProductKey = receiptInfo.PlayerId .. "_" .. receiptInfo.PurchaseId
28    local purchased = false
29    local success, errorMessage = pcall(function()
30        purchased = purchaseHistoryStore:GetAsync(playerProductKey)
31    end)
32    -- If purchase was recorded, the product was already granted
33    if success and purchased then
34        return Enum.ProductPurchaseDecision.PurchaseGranted
35    elseif not success then
36        error("Data store error:" .. errorMessage)
37    end
38 
39    -- Find the player who made the purchase in the server
40    local player = Players:GetPlayerByUserId(receiptInfo.PlayerId)
41    if not player then
42        -- The player probably left the game
43        -- If they come back, the callback will be called again
44        return Enum.ProductPurchaseDecision.NotProcessedYet
45    end
46 
47    -- Look up handler function from 'productFunctions' table above
48    local handler = productFunctions[receiptInfo.ProductId]
49 
50    -- Call the handler function and catch any errors
51    local success, result = pcall(handler, receiptInfo, player)
52    if not success or not result then
53        warn("Error occurred while processing a product purchase")
54        print("\nProductId:", receiptInfo.ProductId)
55        print("\nPlayer:", player)
56        return Enum.ProductPurchaseDecision.NotProcessedYet
57    end
58 
59    -- Record transaction in data store so it isn't granted again
60    local success, errorMessage = pcall(function()
61        purchaseHistoryStore:SetAsync(playerProductKey, true)
62    end)
63    if not success then
64        error("Cannot save purchase data: " .. errorMessage)
65    end
66 
67    -- IMPORTANT: Tell Roblox that the game successfully handled the purchase
68    return Enum.ProductPurchaseDecision.PurchaseGranted
69end
70 
71-- Set the callback; this can only be done once by one script on the server! 
72MarketplaceService.ProcessReceipt = processReceipt

note: roblox does not handle these devproduct purchases, so you must NOT alter the core script. you do not need the above script for a gamepass.
