# AdImpressionResponse

The response you provide that contains a signed payload for a clicked web ad.

```
object AdImpressionResponse
```

## Discussion

This is a response that you provide to the [`Get a Signed Web Ad Impression Payload`](/documentation/SKAdNetworkforWebAds/Get-a-signed-SKAdNetwork-ad-payload-for-a-web-ad.) endpoint. When you create an [`AdImpressionResponse`](/documentation/SKAdNetworkforWebAds/AdImpressionResponse), use the dash-separated string representation of the UUID, which you decode from the `source_nonce` in the [`AdImpressionRequest`](/documentation/SKAdNetworkforWebAds/AdImpressionRequest) that you receive.

> Important:
> The `attributionSourceNonce` in a web ad link, the `source_nonce` in an ``doc://com.apple.skadnetworkforwebads/documentation/SKAdNetworkforWebAds/AdImpressionRequest``, and the `nonce` in this response all represent the same UUID, but the encoding varies.
