MarketPlaceService doesn't print anything?

Asked 201 views1 answers

I'm trying to make a ROBLOX lottery and I need to know when the player buys an asset (Developer product) and It doesn't print anything. FE is on and it's in a serverscript in Workspace. The problem is no output, except for the purchase prompt. Here's the code.

local productId = 31191997
game.Players.PlayerAdded:connect(function(player)

	game:GetService("MarketplaceService").PromptPurchaseFinished:connect(function(player, assetId, isPurchased)
	if isPurchased then
		print(player.Name .. " bought an item with AssetID: " .. assetId)
	else
		print(player.Name .. " didn't buy an item with AssetID: " .. assetId)
	end
end)

	game:GetService("MarketplaceService"):PromptProductPurchase(player, productId)
	

end)

You should record this using ProcessReceipt. Use my Example below:

local MarketplaceService = game:GetService("MarketplaceService")
local ID = 31191997
local PurchaseHistory = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")
 
MarketplaceService.ProcessReceipt = function(receiptInfo) 
    local playerProductKey = receiptInfo.PlayerId .. ":" .. receiptInfo.PurchaseId
    if PurchaseHistory:GetAsync(playerProductKey) then
        return Enum.ProductPurchaseDecision.PurchaseGranted
    end
    for i, player in ipairs(game.Players:GetPlayers()) do
        if player.userId == receiptInfo.PlayerId then
            if receiptInfo.ProductId == ID then
               print("Player has purchased a developer product!")
            end
        end	
    end
    PurchaseHistory:SetAsync(playerProductKey, true)
    return Enum.ProductPurchaseDecision.PurchaseGranted		
end

In the coding above, it recorded the transaction of the developer product if it was bought, if it didn't, nothing happend. Hope this helped! If it did, please Accept me as an answer and we both get reputation!

PS. This is a good source to use if you get stuck again
