Implement interstitial ads in Unity

Implement interstitial ads in your Unity project. Load ad content and display it through C# scripts between gameplay moments or app transitions.
Read time 1 minuteLast updated 4 hours ago
To display a full-screen interstitial ad using the 
Advertisements API
, initialize the SDK, then use the 
Load
 function to load ad content to an ad unit and the 
Show
 function to show the ad. In SDK versions 3.7.0 and later, you can use the 
IUnityAdsLoadListener
 and 
IUnityAdsShowListener
 callbacks to implement logic for when content succeeds or fails to load or show respectively. 
using UnityEngine;
using UnityEngine.Advertisements;
 
public class InterstitialAdExample : MonoBehaviour, IUnityAdsLoadListener, IUnityAdsShowListener
{
  [SerializeField] string _androidAdUnitId = "Interstitial_Android";
  [SerializeField] string _iOSAdUnitId = "Interstitial_iOS";
  string _adUnitId;
 
  void Awake()
  {
    // Get the Ad Unit ID for the current platform:
    _adUnitId = (Application.platform == RuntimePlatform.IPhonePlayer)
    ? _iOSAdUnitId
    : _androidAdUnitId;
  }
 
  // Load content to the Ad Unit:
  public void LoadAd()
  {
    // IMPORTANT! Only load content AFTER initialization (in this example, initialization is handled in a different script).
    Debug.Log("Loading Ad: " + _adUnitId);
    Advertisement.Load(_adUnitId, this);
  }
 
  // Show the loaded content in the Ad Unit:
  public void ShowAd()
  {
    // Note that if the ad content wasn't previously loaded, this method will fail
    Debug.Log("Showing Ad: " + _adUnitId);
    Advertisement.Show(_adUnitId, this);
  }
 
  // Implement Load Listener and Show Listener interface methods: 
  public void OnUnityAdsAdLoaded(string adUnitId)
  {
    // Optionally execute code if the Ad Unit successfully loads content.
  }
 
  public void OnUnityAdsFailedToLoad(string _adUnitId, UnityAdsLoadError error, string message)
  {
    Debug.Log($"Error loading Ad Unit: {_adUnitId} - {error.ToString()} - {message}");
    // Optionally execute code if the Ad Unit fails to load, such as attempting to try again.
  }
 
  public void OnUnityAdsShowFailure(string _adUnitId, UnityAdsShowError error, string message)
  {
    Debug.Log($"Error showing Ad Unit {_adUnitId}: {error.ToString()} - {message}");
    // Optionally execute code if the Ad Unit fails to show, such as loading another ad.
  }
 
  public void OnUnityAdsShowStart(string _adUnitId) { }
  public void OnUnityAdsShowClick(string _adUnitId) { }
  public void OnUnityAdsShowComplete(string _adUnitId, UnityAdsShowCompletionState showCompletionState) { }
}
