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.

GetSubscriptionProductInfoAsync

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.
Paramètres
The ID of the subscription to check.
Retours
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 |

Note that IsSubscribed will be true only when a user has purchased the subscription and the payment has been successfully processed.

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.
