MarketplaceService

Show deprecated

MarketplaceService is the game service that is responsible for in-game transactions.

The most notable functions are MarketplaceService/PromptProductPurchase|PromptProductPurchase and MarketplaceService/PromptPurchase|PromptPurchase, as well as the callback MarketplaceService/ProcessReceipt|ProcessReceipt which must be well defined so that transactions do not fail.

MarketplaceService also has functions that fetch information about developer products (MarketplaceService/GetProductInfo|GetProductInfo and MarketplaceService/GetDeveloperProductsAsync|GetDeveloperProductsAsync), game passes (MarketplaceService/UserOwnsGamePassAsync|UserOwnsGamePassAsync), and other assets (MarketplaceService/PlayerOwnsAsset|PlayerOwnsAsset).

Monetization

Learning to use MarketplaceService is the first step towards learning to monetize a game on Roblox. Another important game service regarding monetization is DataStoreService which is responsible for saving and loading data like that of purchases.

Code Samples

Handling Gamepass Purchase Finished

Below is a screenshot of a game pass purchase prompt. The function in the code sample runs immediately after the player presses “Cancel” or after the player buys the game pass then presses “OK”. Should there be an issue with the purchase, the event also fires.

A game pass purchase prompt

local MarketplaceService = game:GetService("MarketplaceService")

local function gamepassPurchaseFinished(...)
	-- Print all the details of the prompt, for example:
	-- PromptGamePassPurchaseFinished PlayerName 123456 false
	print("PromptGamePassPurchaseFinished", ...)
end

MarketplaceService.PromptGamePassPurchaseFinished:Connect(gamepassPurchaseFinished)
