# ILRD

With **Impression Level revenue data (ILRD)**, you can track and collect ad data.

#|
||

**Parent class**

|

**Method**

||
||

InterstitialAdEventListener

|

`onAdImpression`

||
||

AppOpenAdEventListener

|

`onAdImpression`

||
||

RewardedAdEventListener

|

`onAdImpression`

||
||

BannerAd

|

`onImpression`

||
|#

Each of these methods has the `ImpressionData` parameter with a single method, `getRawData`. This method returns a JSON string with ILRD (see the [table below](#data)).

{% note info %}

The `onAdImpression / onImpression` method is triggered only after the ad impression is recorded.

{% endnote %}

```C#
void _setAdEventListener(RewardedAd ad) {
  ad.setAdEventListener(
    eventListener: RewardedAdEventListener(
      // ... other methods


      onAdImpression: (ImpressionData impressionData) {
        final rawData = impressionData.getRawData();
        debugPrint('[ILRD] Raw: $rawData');

        try {
          final json = jsonDecode(rawData) as Map<String, dynamic>;

          debugPrint('[ILRD] ad_unit_id: ${json['ad_unit_id']}');
          debugPrint('[ILRD] adType: ${json['adType']}');
          debugPrint('[ILRD] currency: ${json['currency']}');
          debugPrint('[ILRD] revenue: ${json['revenue']}');
          debugPrint('[ILRD] revenueUSD: ${json['revenueUSD']}');
          debugPrint('[ILRD] precision: ${json['precision']}');

          final network = json['network'] as Map<String, dynamic>?;
          if (network != null) {
            debugPrint('[ILRD] network.name: ${network['name']}');
            debugPrint('[ILRD] network.ad_unit_id: ${network['ad_unit_id']}');
          }
        } catch (e) {
          debugPrint('[ILRD] Parse error: $e');
        }
      },
    ),
  );
}

```
