MarketplaceService
MarketplaceService is responsible for in-experience transactions. The most notable methods are PromptProductPurchase and PromptPurchase, as well as the callback ProcessReceipt which must be defined so that transactions do not fail.
MarketplaceService also has methods that fetch information about developer products (GetProductInfo and GetDeveloperProductsAsync), passes (UserOwnsGamePassAsync), and other assets (PlayerOwnsAsset, PlayerOwnsBundle).
Understanding MarketplaceService is the first step towards learning to monetize an experience on Roblox, as well as DataStoreService which is responsible for saving and loading data related to purchases.

GetProductInfo
This method provides information about an asset, developer product, or pass given its asset ID and the Enum.InfoType. If no such item exists with the given ID, this method will throw an error. Information about the queried item is provided in a dictionary with the following keys. Note that not all information is provided or necessarily relevant for the kind of product you're querying.

local ASSET_ID = 125378389
local asset = MarketplaceService:GetProductInfo(ASSET_ID)
print(asset.Name .. " :: " .. asset.Description)
GetSubscriptionProductInfoAsync
Note: Because it returns a localized price, you can only call this method from a Script with Enum.RunContext.Client.
Returns the product information of a subscription for the given subscriptionId.
Key | Type | Description |

ExpirationDetails | table | Table containing the details of the subscription expiration. This field will be nil if the subscription is not in the Expired state. If populated, the table contains a ExpirationReason key of type Enum.SubscriptionExpirationReason describing why the subscription is expired. |
Note that this method can only be called from a Script with RunContext of Server. If you only need to determine the IsSubscribed status of a user, it's recommended to use GetUserSubscriptionStatusAsync() as it is faster and more efficient for that particular purpose.
パラメータ
The ID of the subscription to check.
戻り値
GetUserSubscriptionPaymentHistoryAsync
Note: You can only call this method from a Script with Enum.RunContext.Server.
Returns an Array that contains up to one year of the user's subscription payment history for the given subscriptionId, sorted from the most recent status to the least recent.
Each entry in the payment history Array contains the following keys:
Key | Type | Description |
---|---|---|
CycleStartTime | DateTime | DateTime at the start of this particular subscription period. |
CycleEndTime | DateTime | DateTime at the end of this particular subscription period. |
PaymentStatus | Enum.SubscriptionPaymentStatus | Enum.SubscriptionPaymentStatus.Paid if the user paid for this particular subscription period. Enum.SubscriptionPaymentStatus.Refunded if the user refunded this particular subscription period. |
Payment History Length
Only creators affiliated with the subscription product can access up to one year worth of the user's subscription payment history. Non-associated creators can only get the user's current subscription payment status or an empty Array if the user has no active subscription.
Grace Period
Subscription renewal payments can have some processing time. Payment history doesn't return a table for this period. However, in order to preserve a user's subscription experience during the processing period, GetUserSubscriptionStatusAsync() returns IsSubscribed: true for the given user. Don't grant durable items or currency type subscription benefits to the user until after payment has been confirmed for the current cycle.
For example, on August 31, 2023, User A's Subscription B is up for renewal. On September 1, 2023, the payment has yet to be processed. If you call GetUserSubscriptionPaymentHistoryAsync() on September 1, 2023 on User A for Subscription B, the first entry of the return value is:
Key | Value |
---|---|
CycleStartTime | ... |
CycleEndTime | August 31, 2023 |
PaymentStatus | Enum.SubscriptionPaymentStatus.Paid |
Note that since the user is within the grace period, the cycle they have yet to pay for (September 1, 2023) does not appear in the return value at all. This field only populates after the payment has been received and processed.
At the same time, GetUserSubscriptionStatusAsync returns the following result until the renewal payment process fails or the user cancels:
Key | Return |
---|---|
IsSubscribed | True |
IsRenewing | True |

GetUserSubscriptionStatusAsync
Returns a table that contains the subscription status of the user for the given subscriptionId. The table contains the following keys:
Key | Type | Description |
---|---|---|
IsSubscribed | boolean | True if the user's subscription is active. |
IsRenewing | boolean | True if the user is set to renew this subscription after the current subscription period ends. |
Note that IsSubscribed will be true only when a user has purchased the subscription and the payment has been successfully processed. If the payment for a user's initial subscription purchase is still processing or has failed, IsSubscribed returns false. To understand when a user's subscription status has changed, see the Players.UserSubscriptionStatusChanged event.

PlayerOwnsAsset
Returns whether the inventory of the given player contains an asset, given its ID. In the case that a query fails, this method will throw an error, so it's recommended to wrap calls to this method in pcall().
- This method should not be used for passes since they use a separate ID system. Legacy passes that still depend on an asset ID should use UserOwnsGamePassAsync() instead of this method.
- This method cannot be used to check for developer products since they can be purchased multiple times but not owned themselves. Instead, use a data store to save when a player has bought a developer product.

UserOwnsGamePassAsync
Returns true if the player with the given UserId owns the pass with the given gamePassId, not to be confused with an asset ID.
Caching Behavior
Results of this function are remembered so that repeated calls will return quicker. This function will always return true if the player owns the pass upon first entering a server after having purchased the pass. If the pass is purchased in-experience through PromptGamePassPurchase(), this function may return false due to the caching behavior. Conversely, if the player deletes the pass from their inventory, this function may return true despite the player not owning the pass.
パラメータ
Pass ID to check, not to be confused with an asset ID.

PromptBulkPurchaseFinished
Returns when a bulk purchase prompt for avatar items is closed. This fires right as the dialog closes, when the player presses "Cancel" at the prompt or "OK" at the success/error message.
Note: This is not a trusted event from the client. To check if the user owns the items purchased, MarketplaceService.PlayerOwnsAsset or MarketplaceService.PlayerOwnsBundle can be used.

- id: The ID of the asset or bundle (string).
- status: The Enum.MarketplaceItemPurchaseStatus of the purchase (Enum)
PromptGamePassPurchaseFinished

PromptProductPurchaseFinished
Fires when a purchase prompt closes for a developer product, right as the dialog closes when the player presses "Cancel" at the prompt or "OK" at the success/error message.
