The original transaction identifier of a purchase.

## Declaration

```swift
let originalID: UInt64
```

## Discussion

Discussion The original transaction identifier, originalID, is identical to id except when the user restores a purchase or renews a transaction. You can use this value to: Identify one or more renewals for the same subscription. Differentiate a purchase transaction from a restore or a renewal transaction. For restore and renewal transactions, the original transaction identifier, originalID, and transaction identifier, id, differ. Match a transaction in the app with a transaction you receive on your server in an App Store Server Notifications event.
