# appAccountToken

A UUID that associates the transaction with a customer on your service.

## Declaration

```data
uuid appAccountToken
```

## Mentioned in

App Store Server Notifications changelog

## Discussion

Discussion When a customer initiates an in-app purchase, your app may create 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 appAccountToken field contains that value.
