SKOverlay

Implement Apple’s SKOverlay feature in Unity Exchange ads to display App Store overlays that promote app installs within the iOS environment.
Read time 1 minuteLast updated 4 hours ago
SKOverlay is a dynamic ad format resembling a native banner at the bottom of the screen. It prompts users to download offered apps instantly without redirection to the App Store or Storekit page, enhancing ad performance and increasing impressions per mille (IPM) for supporting publishers with updated SDKs. SKOverlay also supports SKAdNetwork postbacks.

Bid Request

Unity flags in the bid request if SKOverlay is allowed for each specific session, since some publishers disable the SKOverlay feature for their app. If SKOverlay is allowed, Unity sends a single extension to flag: 
bidRequest.imp.ext.skadn.skoverlay: 1
.

Bid Response

For sessions that are sent with 
bidRequest.imp.ext.skadn.skoverlay: 1
, Unity allows the DSP to control if they would like to enable the feature or not. Unity expects to read your bid response that either enables or disables a SKOverlay in your app, as follows:
