# Interstitial Ad

Below are the steps to load and show an Interstitial ad on your app

Before loading ads, have your app initialize Adster Unity Bridge SDK.\
This needs to be done only once, ideally at app launch.

1. Call `LoadInterstitialAd()`method as per below format

<pre class="language-csharp"><code class="lang-csharp"><strong>AdsterBridgeUtil.LoadInterstitialAd("Your_placement_name", "gameobject_name_goes_here");
</strong></code></pre>

2. Declare `OnInterstitialAdEvent()` method as per below format

{% tabs %}
{% tab title="C#" %}

```csharp
public void OnInterstitialAdEvent(string message)
    {
        // Process ad events based on the message
        if (message == "AdLoaded")
        {
            Debug.Log("Interstitial ad successfully loaded.");
        }
        else if (message.StartsWith("AdFailed:"))
        {
            string error = message.Substring("AdFailed:".Length);
            Debug.LogError($"Failed to load interstitial ad: {error}");
        }
        else if (message == "AdOpened")
        {
            Debug.Log("Interstitial ad opened.");
        }
        else if (message == "AdClosed")
        {
            Debug.Log("Interstitial ad closed.");
        }
        else if (message == "AdClicked")
        {
            Debug.Log("Interstitial ad clicked.");
        }
        else if (message == "AdImpression")
        {
            Debug.Log("Interstitial ad impression recorded.");
        }
        else if (message.StartsWith("AdRevenuePaid"))
        {
            Debug.Log(message);
            string[] parts = message.Split('|');
            if (parts.Length == 4)
            {
                string revenue = parts[1];
                string adUnit = parts[2];
                string network = parts[3];
                Debug.Log($"[AdRevenue] Revenue: {revenue}, AdUnit: {adUnit}, Network: {network}");
            
            return;
            }
        }
    }
```

{% endtab %}
{% endtabs %}

3. Inside the `AdLoaded` callback method invoke `ShowInterstitialAd()` method as below to show AdSter interstitial ad above any scene/view.

{% tabs %}
{% tab title="C#" %}

```csharp
AdsterBridgeUtil.ShowInterstitialAd("gameobject_name_goes_here");
```

{% endtab %}
{% endtabs %}
