Rewarded interstitial

Select platform: Android iOS Unity Flutter

Rewarded interstitial is a type of incentivized ad format that allows you offer rewards for ads that appear automatically during natural app transitions. Unlike rewarded ads, users aren't required to opt-in to view a rewarded interstitial.

Prerequisites

Complete the Get started guide .

Implementation

The primary steps to integrate rewarded interstitial ads are as follows:

Load an ad
[Optional] Validate SSV callbacks
Register for callbacks
Display the ad and handle the reward event

Load an ad

Loading an ad is accomplished using the load(adUnitID:request) method on the GADRewardedInterstitialAd class.

Swift

  func 
  
 loadAdManagerRewardedInterstitialAd 
 () 
  
 async 
  
 { 
  
 do 
  
 { 
  
 rewardedInterstitialAd 
  
 = 
  
 try 
  
 await 
  
 RewardedInterstitialAd 
 . 
 load 
 ( 
  
 // Replace this ad unit ID with your own ad unit ID. 
  
 with 
 : 
  
 " adUnitID 
" 
 , 
  
 request 
 : 
  
 AdManagerRequest 
 ()) 
  
 rewardedInterstitialAd 
 ?. 
 fullScreenContentDelegate 
  
 = 
  
 self 
  
 } 
  
 catch 
  
 { 
  
 print 
 ( 
 "Rewarded ad failed to load with error: 
 \( 
 error 
 . 
 localizedDescription 
 ) 
 " 
 ) 
  
 } 
 }

Replace adUnitID with your ad unit ID.

[Optional] Validate server-side verification (SSV) callbacks

Apps that require extra data in server-side verification callbacks should use the custom data feature of rewarded ads. Any string value set on a rewarded ad object is passed to the custom_data query parameter of the SSV callback. If no custom data value is set, the custom_data query parameter value won't be present in the SSV callback.

The following code sample demonstrates how to set custom data on a rewarded interstitial ad object before requesting an ad.

Swift

  private 
  
 func 
  
 validateAdManagerServerSideVerification 
 () 
  
 async 
  
 { 
  
 do 
  
 { 
  
 rewardedInterstitialAd 
  
 = 
  
 try 
  
 await 
  
 RewardedInterstitialAd 
 . 
 load 
 ( 
  
 // Replace this ad unit ID with your own ad unit ID. 
  
 with 
 : 
  
 " adUnitID 
" 
 , 
  
 request 
 : 
  
 AdManagerRequest 
 ()) 
  
 let 
  
 options 
  
 = 
  
 ServerSideVerificationOptions 
 () 
  
 options 
 . 
 customRewardText 
  
 = 
  
 "" 
  SAMPLE_CUSTOM_DATA_STRING 
 
 "" 
  
 rewardedInterstitialAd 
 ?. 
 serverSideVerificationOptions 
  
 = 
  
 options 
  
 } 
  
 catch 
  
 { 
  
 print 
 ( 
 "Rewarded ad failed to load with error: 
 \( 
 error 
 . 
 localizedDescription 
 ) 
 " 
 ) 
  
 } 
 } 
   RewardedInterstitialAdSnippets 
 . 
 swift

Objective-C

  - 
 ( 
 void 
 ) 
 validateAdManagerServerSideVerification 
  
 { 
  
 // Replace this ad unit ID with your own ad unit ID. 
  
 [ 
 GADRewardedInterstitialAd 
  
 loadWithAdUnitID

 " adUnitID

 { 
  
 if

   RewardedInterstitialAdSnippets

Replace SAMPLE_CUSTOM_DATA_STRING with your custom data.

Register for callbacks

To receive notifications for presentation events, you must assign the GADFullScreenContentDelegate to the fullScreenContentDelegate property of the returned ad:

Swift

  rewardedInterstitialAd 
 ?. 
 fullScreenContentDelegate 
  
 = 
  
 self  RewardedInterstitialAdSnippets 
 
 
 . 
 swift

func adDidRecordImpression ( _ ad : FullScreenPresentingAd ) { print ( " \( #function ) called." ) } func adDidRecordClick ( _ ad : FullScreenPresentingAd ) { print ( " \( #function ) called." ) } func adWillPresentFullScreenContent ( _ ad : FullScreenPresentingAd ) { print ( " \( #function ) called." ) } func adWillDismissFullScreenContent ( _ ad : FullScreenPresentingAd ) { print ( " \( #function ) called." ) } func adDidDismissFullScreenContent ( _ ad : FullScreenPresentingAd ) { print ( " \( #function ) called." ) // Clear the rewarded interstitial ad. rewardedInterstitialAd = nil } func ad ( _ ad : FullScreenPresentingAd , didFailToPresentFullScreenContentWithError error : Error ) { print ( " \( #function ) called with error: \( error . localizedDescription ) ." ) } RewardedInterstitialAdSnippets . swift

func adDidRecordImpression ( _ ad : FullScreenPresentingAd ) { print ( " \( #function ) called" ) } func adDidRecordClick ( _ ad : FullScreenPresentingAd ) { print ( " \( #function ) called" ) } func ad ( _ ad : FullScreenPresentingAd , didFailToPresentFullScreenContentWithError error : Error ) { print ( " \( #function ) called" ) } func adWillPresentFullScreenContent ( _ ad : FullScreenPresentingAd ) { print ( " \( #function ) called" ) } func adWillDismissFullScreenContent ( _ ad : FullScreenPresentingAd ) { print ( " \( #function ) called" ) } func adDidDismissFullScreenContent ( _ ad : FullScreenPresentingAd ) { print ( " \( #function ) called" ) // Clear the rewarded interstitial ad. rewardedInterstitialAd = nil } RewardedInterstitialViewModel . swift

- ( void ) adDidRecordImpression: ( id<GADFullScreenPresentingAd> ) ad { NSLog ( @"%s called" , __PRETTY_FUNCTION__ ); } - ( void ) adDidRecordClick: ( id<GADFullScreenPresentingAd> ) ad { NSLog ( @"%s called" , __PRETTY_FUNCTION__ ); } - ( void ) adWillPresentFullScreenContent: ( id<GADFullScreenPresentingAd> ) ad { NSLog ( @"%s called" , __PRETTY_FUNCTION__ ); } - ( void ) adWillDismissFullScreenContent: ( id<GADFullScreenPresentingAd> ) ad { NSLog ( @"%s called" , __PRETTY_FUNCTION__ ); } - ( void ) adDidDismissFullScreenContent: ( id<GADFullScreenPresentingAd> ) ad { NSLog ( @"%s called" , __PRETTY_FUNCTION__ ); // Clear the rewarded interstitial ad. self . rewardedInterstitialAd = nil ; } - ( void ) ad: ( id ) ad didFailToPresentFullScreenContentWithError: ( NSError * ) error { NSLog ( @"%s called with error: %@" , __PRETTY_FUNCTION__ , error . localizedDescription ); } RewardedInterstitialAdSnippets . m

func showRewardedInterstitialAd () { guard let rewardedInterstitialAd = rewardedInterstitialAd else { return print ( "Ad wasn't ready." ) } // The UIViewController parameter is an optional. rewardedInterstitialAd . present ( from : nil ) { let reward = rewardedInterstitialAd . adReward print ( "Reward received with currency \( reward . amount ) , amount \( reward . amount . doubleValue ) " ) // TODO: Reward the user. } } RewardedInterstitialAdSnippets . swift

var rewardedInterstitialBody : some View { // ... } . onChange ( of : showAd , perform : { newValue in if newValue { viewModel . showAd () } } ) RewardedInterstitialContentView . swift

func showAd () { guard let rewardedInterstitialAd = rewardedInterstitialAd else { return print ( "Ad wasn't ready." ) } rewardedInterstitialAd . present ( from : nil ) { let reward = rewardedInterstitialAd . adReward print ( "Reward amount: \( reward . amount ) " ) self . addCoins ( reward . amount . intValue ) } } RewardedInterstitialViewModel . swift

- ( void ) showRewardedInterstitialAd { [ self . rewardedInterstitialAd presentFromRootViewController : self userDidEarnRewardHandler : ^ { GADAdReward * reward = self . rewardedInterstitialAd . adReward ; NSString * rewardMessage = [ NSString stringWithFormat : @"Reward received with " @"currency %@ , amount %ld" , reward . type , [ reward . amount longValue ]]; NSLog ( @"%@" , rewardMessage ); // TODO: Reward the user. }]; } RewardedInterstitialAdSnippets . m
