# app_account_token

The UUID that an app optionally generates to map a customer’s in-app purchase with its resulting App Store transaction.

## Declaration

```data
string app_account_token
```

## Discussion

Discussion When a customer initiates an in-app purchase, you can optionally generate an appAccountToken(_:) and send it to the App Store. The App Store returns the same value in appAccountToken in the transaction information after the customer completes the purchase. If you’re using the Original API for In-App Purchase and provide a UUID in the applicationUsername property, then the app_account_token field contains that value.
