DT FairBid enables you to access detailed information for each impression through the Impressions Callback APIs. The information includes, for example, which demand source served the ad, and the expected or exact revenue associated with it. In addition, it contains granular details to allow you to analyze and ultimately, optimize both your ad monetization and user acquisition strategies. 

To enrich and elaborate the insights you can receive, this information can be called by two different APIs relating to different stages at the impression lifetime:

• Once the ad is shown (OnShow) - starting from DT FairBid 2.3.0
• Before the ad is shown, once there is a Fill – an ad is available to display (OnAvailable) - starting from DT FairBid 3.11.0

void OnShow(string placementId, ImpressionData 
impressionData); 

void OnShowFailure(string placementId, ImpressionData 
impressionData);

The example below showcases how to access these data on an Interstitial integration. The integration for Rewarded and Banners is similar.

Interstitial.SetInterstitialListener(new MyInterstitialListener());

class MyInterstitialListener : InterstitialListener
{
    public void OnShow(string placementId, ImpressionData 
    impressionData)
    {
        string netPayout = impressionData.netPayout;
        string currency = impressionData.currency;
        int impressionDepth = impressionData.impressionDepth;
        ImpressionData.PriceAccuracy priceAccuracy = 
        impressionData.priceAccuracy;
        Debug.Log($"Placement {placementId} has been shown with a 
        net payout of
        {netPayout} {currency} with accuracy: {priceAccuracy} and 
        impression depth:
        {impressionDepth}");
    }
}

string placementId = "12345";
if (Interstitial.IsAvailable(placementId))
{
    Interstitial.Show(placementId);
}

In this example, you can expect the log to appear as:

Placement 12345 has been shown with a net payout of 4.000000 USD 
with accuracy: PREDICTED and impression depth: 1

public void OnAvailable(string placementId) {
    ImpressionData impressionData = 
    Interstitial.GetImpressionData(placementId);
}

public void OnAvailable(string placementId) {
    ImpressionData impressionData = 
    Rewarded.GetImpressionData(placementId);
}

Impression Depth

Impression depth represents the amount of impressions in a given session per ad format (Rewarded, Interstitial and Banner).

Impression depth can be directly accessed from each ad format class (access all code snippets here). Alternatively, it can be accessed through the ImpressionLevelData object as shown in the snippets above.

The impression depth for each ad format continues to increase throughout the session as more ads are displayed.

It is reset only when:

• The session ends (app is killed)
• SDK considers the session has “timed out”

Session Timeout

Session timeout or “session background timeout” represents the amount of time the user needs to spend with the app in the background before we consider them to be back to user engagement levels similar to a fresh new session. At this point, for all ad formats, the impression depth is reset to 0.

The Session timeout value is 30 minutes by default. 

Snippets

The example below illustrates how you can access the impressionDepth value for all ad formats (Rewarded, Interstitial and Banner),

int impressionDepth = Banner.GetImpressionDepth();

int impressionDepth = Interstitial.GetImpressionDepth();

int impressionDepth = Rewarded.GetImpressionDepth();
