# latest(for:) Gets the customer’s most recent transaction for an In-App Purchase. ``` static func latest(for productID: String) async -> VerificationResult? ``` ## Parameters `productID` The product identifier that the method uses to look up the most recent transaction. ## Return Value A [`VerificationResult`](/documentation/StoreKit/VerificationResult) with a single [`Transaction`](/documentation/StoreKit/Transaction), or `nil` if the customer hasn’t purchased the product. ## Discussion Call this method for any type of In-App Purchase. The following code example illustrates requesting the most recent transaction to determine whether the customer purchased the product indicated by the string `productIdentifier`: ```swift guard let verificationResult = await Transaction.latest(for: productIdentifier) else { // The customer hasn't purchased this product. return } switch verificationResult { case .verified(let transaction): // Check the transaction and give the customer access to purchased // content as appropriate. ... case .unverified(let transaction, let verificationError): // Handle unverified transactions based // on your business model. ... } ``` By default, when the property list key is `false`, this method excludes finished consumable in-app purchases unless they are refunded or revoked. If you set the property list key to `true`, this method returns all transactions, including consumable In-App Purchases that your app marked as finished ([`finish()`](/documentation/StoreKit/Transaction/finish())). --- Copyright © 2026 Apple Inc.
