# AppTransactionIdNotFoundError

An error that indicates the app transaction identifier wasn’t found.

```
object AppTransactionIdNotFoundError
```

## Discussion

A request returns this error if you call the [`Claim Seat`](/documentation/AppStoreServerAPI/Claim-Seat) or [`Associate Seat`](/documentation/AppStoreServerAPI/Associate-Seat) endpoint with an [`appTransactionId`](/documentation/AppStoreServerAPI/appTransactionId) that the App Store can’t find. Check that the value is the customer’s app transaction identifier for your app, in the same environment as the request.
