## Discussion

Discussion Set this property to your ad network ID. Ad networks obtain an ad network identifier during registration. Ad networks must share their ad network identifiers with participating app developers. Apps that display ads must include the ad network ID in their Info.plist to initiate the app install validation process. For more information about acquiring your ad network ID, see Registering an ad network.
