You’d have to sort the returned validated purchases by `purchaseTime`, or lookup the specific purchase you’re looking for based on its metadata.

Thanks for your reply, but when I purchased an iap, it saved all previous transactions

</div>

```auto
const sortedPurchases = purchaseIapValidation.validatedPurchases.sort((a: nkruntime.ValidatedPurchase, b: nkruntime.ValidatedPurchase) => b.purchaseTime - a.purchaseTime);

```

```auto
const latestUnseenPurchase = sortedPurchases.find((p) => !p.seenBefore);

```

This is solution for some time, but sometimes error occurs.
