5.4.2

[5.4.2] - 2026-07-24

Added

• Payment Providers - IPaymentProvidersExtendedPurchaseService.SetCustomReferenceId(string?) — sets the CustomReferenceId sent on new Payment Provider orders, echoed back on the order and its webhooks so you can reconcile IAP orders with your own internal system.
• Payment Providers - IPaymentProvidersExtendedPurchaseService.SetCustomMetadata(IReadOnlyDictionary<string, string>?) — sets an arbitrary string key/value dictionary sent as Metadata on new Payment Provider orders.
• Payment Providers - IPaymentProvidersOrderInfo — Payment-Provider-specific order details accessible via order.Info.PaymentProviders. Exposes CustomReferenceId (the value set via SetCustomReferenceId) and Metadata (the value set via SetCustomMetadata).
• Authoring - Deploy auto-creates any webshop categories referenced by catalog items but missing from the categories document. Existing categories are left untouched.

Changed

• Package description - Corrected the setup instructions to point to Services > In-App Purchasing > Configure, replacing the outdated Window > General > Services path.
• Purchasing - Purchases with a store specific id not found in the current catalog will attempt to find the matching uSku in the Remote Catalog
• Purchase Options UI - Replace "Google Pay" and "Apple Pay" assets with appropriate "Google Play" and "In-App Purchase" assets.

Fixed

• GooglePlay - A failed purchases query (non-OK billing result) was indistinguishable from a user owning no purchases, so a lapsed subscription could not be reliably detected.
  • FetchPurchases now invokes OnPurchasesFetchFailed on failure with the billing response code instead of OnPurchasesFetched with an empty list.
  • CheckEntitlement now reports EntitlementStatus.Unknown on failure instead of EntitlementStatus.NotEntitled when the purchases query fails.
• Apple (StoreKit 2) - FetchPurchases no longer reports expired subscriptions as pending purchases via OnPurchasePending.
• Apple (StoreKit 2) - Purchase failures were reported with the wrong PurchaseFailureReason. Unknown errors were surfaced as either ValidationFailure or SignatureInvalid.
• Apple (StoreKit 2) - Purchase failures that have a specific PurchaseFailureReason are now more accurately reported instead of being Unknown.
• Apple (StoreKit 2) - confirm success (OnPurchaseConfirmed) is now reported only after the native Transaction.finish call has completed, instead of unconditionally before it ran. A finish that does not find a matching unfinished transaction now reports a DuplicateTransaction confirm failure, as the transaction has likely already been finished.
• Apple - Added missing tvOS 18.1 availability check, causing 'ExternalPurchaseCustomLink' is only available in tvOS 18.1 or newer build failure.

5.4.1

[5.4.1] - 2026-07-07

Changed

5.3.1

[5.3.1] - 2026-05-27

Added

• Xbox - Added purchase verification support through the Microsoft Store Collections service. See In-app purchases for Xbox games for more details.

Fixed

• Fixed compile errors caused by naming collisions when a project imports a third-party package that exposes a top-level UnityUtil namespace.
• Google - Fixed a race condition where purchases could be silently lost when FetchPurchases completed before FetchProducts populated the product details cache. Missing product details are now pre-fetched before purchases are built.
• Google - Fixed a NullReferenceException when constructing a GooglePurchase for an owned purchase whose AccountIdentifiers are null (test purchases or apps that don't call SetObfuscatedAccountId).
• Google - Fixed a NullReferenceException in ProductDetailsConverter.BuildProductDescription when a product has no subscription offer details (returned as null by Google Play for non-subscription products).
• Google - Fixed a NullReferenceException where Purchase references received from QueryPurchasesAsync could become invalid across an async boundary. The references are now cloned to long-lived global JNI references inside the billing-client callback.

5.3.0

• Apple - Fixed InvalidPublicKeyException exception being thrown when creating a CrossPlatformValidator.
