# postbacks

An array of test postbacks you set in the testing environment.

```
var postbacks: [SKAdTestPostback] { get }
```

## Discussion

Use this property to check that your updates to the test postbacks, such as conversion value updates, are working as expected. See [`setPostbacks(_:)`](/documentation/StoreKitTest/SKAdTestSession/setPostbacks(_:)) for information on adding postbacks to the test session.
