# SKPaymentTransaction

An object in the payment queue.

```
class SKPaymentTransaction
```

## Overview

A payment transaction is created whenever a payment is added to the payment queue. The system delivers transactions to your app when the App Store finishes processing the payment. Completed transactions provide a receipt and transaction identifier that your app can use to save a permanent record of the processed payment.
