Impression Level Data

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, 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 get, this information can be called by two different APIs that refers to different stages at the impression lifetime:

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

Glossary Table

Property Name Type Description Examples
advertiserDomain String (nullable) Advertiser’s domain when available. Used as an identifier for a set of campaigns for the same advertiser
campaignId String (nullable) Campaign ID when available used as an identifier for a specific campaign of a certain advertiser



countryCode String (nullable) Country location of the ad impression(in ISO country code)


creativeId String (nullable) Creative ID when available. Used as an identifier for a specific creative of a certain campaign. This is particularly useful information when a certain creative is found to cause user experience issues 169493819
currency String Currency of the payout USD
demandSource String (nullable) Demand Source name is the name of the buy-side / demand-side entity that purchased the impression. When mediated networks win an impression, you’ll see the mediated network’s name. When a DSP buying through the programmatic marketplace wins the impression, you’ll see the DSP’s name.


Liftoff RTB
Meta Audience bidder
Liftoff Monetize
InMobi Bidder

impressionDepth Integer The amount of impressions in current session for the given Placement Type 1
impressionId String (nullable) A unique identifier for a specific impression 5699232551401720289
jsonString String A JSON representation of the data serialized to a String.  
netPayout String
Net payout for an impression. The value accuracy is returned in the priceAccuracy field. The value is provided in units returned in the currency field. 0.0155
networkInstanceId String (nullable) The mediated ad network’s original Placement/Zone/Location/Ad Unit ID that you created in their dashboard. For ads shown by the DT Exchange the networkInstanceId is the Placement ID you created in the  DT Console. c38b236a7b613dc2
placementType enum The Placement Type for the impression, corresponds to your choice in the DT Console. Types available:
priceAccuracy enum Accuracy of the netPayout value. May return one of the following:

PROGRAMMATIC - When netPayout is the exact and committed value of the impression, available when impressions are won by programmatic buyers.
PREDICTED - When DT’s estimation of the impression value is based on historical data from non-programmatic mediated network’s reporting APIs
* UNDISCLOSED - When the demand source does not agree to disclose the payout of every impression - in such cases the netPayout is ‘0’
renderingSDK String (nullable) Name of the SDK in charge of rendering the ad


DT Exchange

renderingSDKVersion String (nullable) Version of the SDK rendering the ad.
(NOTE: When Google AdMob, Google Bidding or Google Ad Manager renders an impression, the renderingSDKVersion shows the Google Play Services version)
variantId String (Added since 3.11.0) Variant Identifier. When running a multi test experiment, this ID will help you identify which variant was delivered on the device. 123456

Impression Data Upon Showing the Ad

All ad formats (Interstitial, Rewarded and Banner) provide you access to the ImpressionData object through their callback APIs:

public void onShow(@NonNull String placementId, @NonNull ImpressionData impressionData)

public void onShowFailure(@NonNull String placementId,  @NonNull ImpressionData impressionData)

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

Interstitial.setInterstitialListener(new InterstitialListener() {
    public void onShow(@NonNull String placementId, @NonNull ImpressionData impressionData) {
                double netPayout = impressionData.getNetPayout();
                String currency = impressionData.getCurrency();
                ImpressionData.PriceAccuracy priceAccuracy = impressionData.getPriceAccuracy();
								int impressionDepth = impressionData.getImpressionDepth();
                String message = String.format("Placement %s has been shown with a net payout of %f %s with accuracy: %s and impression depth: %s", placementId, netPayout, currency, priceAccuracy, impressionDepth);
                Log.d(TAG, message);

String placementId = "12345";
if (Interstitial.isAvailable(placementId)) {, context);

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

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

Impression Data Before Showing the Ad

Starting on SDK 3.11.0, for Interstitials and Rewarded ads, you can also access the same information before showing the ad.

This information will be available as soon as you have a fill for that placement. If the placement for which you are requesting the impression data does not have a fill, the API will return null.

Calling this API at different moments maybe result in different values for the impression depth field, since impression depth is counted for the ad type, regardless of placement. More information below.


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 will keep increasing throughout the session as more ads get 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.


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

int impressionDepth = Interstitial.getImpressionDepth();

int impressionDepth = Banner.getImpressionDepth();

int impressionDepth = Rewarded.getImpressionDepth();
