How to detect if a product is purchased instantly

So i am trying to make a purchase system that detects immediately after its purchased and not when you press the OK button, i dont really have a screenshot atm but i want to detect when you click the purchase button and it validates the purchase and not when clicking the OK button right after you purchased it.

i tried everything but couldnt do what i wanted to do

this is so that if a player gets disconnected right after making the purchase they dont get scammed, how can i do this?

how they get scammed if they leave immediately after the purchase , also no one is going to leave the game after purchasing any thing immediately they may get disconnected , you can save the purchase in datastore so if the any player purchase a developer product and then disconnected it will be saved that player purchase that item and did not use it

Not something I work with much right now, but I think pcalls prevent you accidentally giving them an item if they get disconnected immediately after purchase.

no they do not , pcalls just prevent the code from throwing errors

Yes I know, but for purchasing developer products wouldn’t the pcalls success be false with a reason saying player left?

if not then what about the ProcessReceipt thing?

no it will not , it will return false if it failed to prompt the user to buy the product

ProcessReceipt in an event it will fire when a player try to buy a developer product , it gives you a ReceiptInfo table , you need to return an Enum.ProductPurchaseDecision to the event , you do not need to wrap this in a pcall

pcall stands for “Protected Call” all it is job is to do not let the code inside to throw errors

#9

But used to prevent serious failures and usually for API kind of stuff.

yes , in this case it will return false if it failed to prompt the user to purchase the developer product

Possibly PromptProductPurchaseFinished

local MarketplaceService = game:GetService("MarketplaceService")

local function onPromptPurchaseFinished(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

MarketplaceService.PromptPurchaseFinished:Connect(onPromptPurchaseFinished)
