# fidelityType

An integer that indicates the type of ad impression, StoreKit-rendered or view-through.

```
var fidelityType: Int { get set }
```

## Discussion

SKAdNetwork versions 2.2 and later require a [`fidelityType`](/documentation/StoreKitTest/SKAdTestPostback/fidelityType) parameter for ad validation signatures. For view-through ads, use a fidelity type value of `0`. For StoreKit-rendered ads, use the value `1`.
