# latest(for:)

Gets the customer’s most recent transaction for an In-App Purchase.

## Declaration

```swift
static func latest(for productID: String) async -> VerificationResult<Transaction>?
```

## Parameters

- `productID`: The product identifier that the method uses to look up the most recent transaction.

## Return Value

Return Value A VerificationResult with a single Transaction, or nil if the customer hasn’t purchased the product.

## Discussion

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: 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 SKIncludeConsumableInAppPurchaseHistory property list key is false, this method excludes finished consumable in-app purchases unless they are refunded or revoked. If you set the SKIncludeConsumableInAppPurchaseHistory property list key to true, this method returns all transactions, including consumable In-App Purchases that your app marked as finished (finish()).
