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. Be extra mindful when using these features, as failed sales and sale-related bugs can be incredibly frustrating to deal with. Another important game service regarding monetization is DataStoreService which is responsible for saving and loading data like that of purchases. When processing purchases, it is often a good idea to check using data stores that a player hasn’t already been granted a product. Remember: all of the current financial rules of Roblox apply to in-game sales. At the moment, members of Builders Club will earn 70% of the total cost of the transaction and 10% for affiliate gear sales. If you are not a Builders Club member, you instead earn 10% of the total cost of the transaction.

Purchase Prompt

Below is an example of an in-game developer product purchase prompt for a product called “XP Boost”, with a price of R$ 25. The player is presented with the choice “Buy Now” or “Cancel”. Upon confirming the purchase, the MarketplaceService/ProcessReceipt|ProcessReceipt callback will be invoked with information about the purchase so the game may grant the product (in this case, the XP Boost). In studio, purchases will not charge the developer account and will be marked as such in the prompt.

Sale Processing

Processing the sales of developer products is done by setting the MarketplaceService/ProcessReceipt|ProcessReceipt callback once. This callback should grant the bonus associated with a developer product and return Enum.ProductPurchaseDecision.PurchaseGranted.
