# Ad network install-validation keys

Specify key values that validate and associate an app installation with an ad campaign.

## Overview

Overview Ad networks use these keys when calling the product view controller’s loadProduct(withParameters:completionBlock:) method. These keys describe an ad impression in an advertising campaign. The information they contain associates an app installation with an ad campaign. The SKStoreProductParameterITunesItemIdentifier key identifies the advertised app. Include all the required validation keys in the parameter dictionary for the SKAdNetwork version you’re using. You also use the values of these keys to generate a signature for the ad impression. For more information, see Generating the signature to validate StoreKit-rendered ads.
