Configure Mediation

Test Mode

The Mediation SDK includes a Test Mode method that will allow you to test your partner integrations and get their test ads. To enable Test Mode, simply set the following method to true after starting the Mediation SDK. Remember to remove it or set the method to false before releasing your app.


Privacy Methods

The following privacy methods are used to set different privacy settings:



// or
// or
  • By sending setSubjectToCoppa(true), you indicate that you want your content treated as child-directed for purposes of COPPA. We will take steps to disable interest-based advertising for such ad requests.
  • By sending setSubjectToCoppa(false), you indicate that you don't want your content treated as child-directed for purposes of COPPA. You represent and warrant that your applications and services are not directed towards children and that you will not provide any information to Mediation from a user under the age of 13.



// or
// or
  • By sending setSubjectToGDPR(true), you indicate that GDPR is applied to this user from your application.
  • By sending setSubjectToGDPR(false), you indicate that GDPR is not applied to this user from your application.


// or
// or
  • By sending setUserHasGivenConsent(true), you indicate that this user from your application has given consent to share personal data for behavior-targeted advertising.
  • By sending setUserHasGivenConsent(false), you indicate that this user from your application has not given consent to use its personal data for behavior-targeted advertising, so only contextual advertising is allowed.



// or
// or
  • By sending setCCPAConsent(true), you indicate that this user from your application has given consent to share personal data for behavior-targeted advertising under CCPA regulation.
  • By sending setCCPAConsent(false), you indicate that this user from your application has not given consent to allow sharing personal data for behavior-targeted advertising under CCPA regulation.



The Mediation SDK will send CCPA information to the bidding networks via the mediation adapters, where the information is stored.


Starting in version 2.9.0, the Mediation SDK introduces keywordsโ€”key-value pairs that can be set to enable real-time targeting of line items.

Set Keywords

To set keywords, you will need to first create a Mediation ad object. Then, use the set() method to add key-value keywords pair. The set method returns a boolean indicating whether or not the keyword has been successfully set.

// Create a Helium ad object.
val interstitialAd = HeliumInterstitialAd(placementName, heliumInterstitialAdListener)
val rewardedAd = HeliumRewardedAd(placementName, heliumRewardedAdListener)
val bannerAd = HeliumBannerAd(context, placementName, bannerSize, heliumBannerAdListener)
interstitialAd.keywords["i12_keyword1"] = "i12_value1"
rewardedAd.keywords["rwd_keyword1"] = "rwd_value1"
bannerAd.keywords["bnr_keyword1"] = "bnr_value1"
// Create a Helium ad object.
HeliumInterstitialAd interstitialAd = new HeliumInterstitialAd(placementName, heliumInterstitialAdListener);
HeliumRewardedAd rewardedAd = new HeliumRewardedAd(placementName, heliumRewardedAdListener);
HeliumBannerAd bannerAd = new HeliumBannerAd(context, placementName, bannerSize, heliumBannerAdListener);

interstitialAd.getKeywords().set("i12_keyword1", "i12_value1");
rewardedAd.getKeywords().set("rwd_keyword1", "rwd_value1");
bannerAd.getKeywords().set("bnr_keyword1", "bnr_value1");

Remove Keywords

To remove keywords that have been set, simply use the remove() method and pass in the key whose value you would like to remove. The remove method returns the value of the key removed.

// Remove keyword
// Remove keyword



The keywords API has restrictions for setting keys and values. The maximum number of characters allowed for each key name is 64 characters. For values, it is 256 characters.

Impression Level Revenue Data (ILRD)

Impression Level Revenue Data (ILRD) is data we already collect on the server side and store in our database today. This feature allows publishers to get access to this data.

An ILRD event occurs every time an impression is tracked. The fields that a publisher is interested in are broken down as follows:

ILRD KeyValueILRD Description
"ad_revenue"DoubleDouble-precision floating point
"currency_type"StringAlways USD
"country"StringThree-letter country code ISO_3166-1_alpha-3 (ex. "USA")
"line_item_name"StringMediation line item name
"line_item_id"StringMediation line item id
"network_name"StringNetwork Name
"network_placement_id"StringPartner placement name
"network_type"StringEither bidding or mediation
"placement_name"StringMediation placement name
"placement_type"StringAd type:
- interstitial
- rewarded
- banner
"precision"StringOne of the following:
- estimated
- exact
- publisher_defined
- undisclosed
 "ad_revenue": 0.055,
 "currency_type": "USD",
 "country": "USA",
 "impression_id": "ae112f3dccf90c705f2d3b1324605e9d16687725",
 "line_item_name": "helium_rv_T1_tapjoy_high",
 "line_item_id": "33f6b0ca-1b3c-4e69-80dd-b57db13db159",
 "network_name": "tapjoy",
 "network_placement_id": "tapjoy_RV_0_25",
 "network_type": "mediation",
 "placement_name": "heliumTapjoyTest",
 "placement_type": "rewarded",
 "precision": "publisher_defined"

Publishers can receive ILRD data in two ways:

  1. On Android, we provide a global notification that gives publishers access to ILRD data on each impression event shown in real time.
  2. For API access, we can provide an ILRD reporting API where publishers can request a custom report (CSV) of all their ILRD data filtered by appId, min_date, max_date.

Publishers can use ILRD data in several ways:

  • You can listen to the data via SDK notifications in real-time and ship it to your own servers or to other MMPs such as AppsFlyer or Adjust.
  • You can manually request a report via the API endpoint and analyze it at your convenience.


Note: Meta Audience Network Ad Revenue

  • Unlike other networks, Meta prohibits Mediation from sharing the real ad_revenue value of Meta Audience Network impressions with publishers.
  • Instead, Mediation is only allowed to share the average of aggregated eCPMs of Meta Audience Network line items.

Rewarded Callbacks

Setting the User ID and Custom Data through the SDK.

Setting User Identifier

The user identifier property is found on the HeliumSdk object. This property may be set anytime after SDK initialization.


Setting Custom Data

The custom data property is found on the HeliumRewardedAd instance, and has a maximum character limit of 1000 characters. In the event that the limit is exceeded, the customData property will be set to null.

Custom data may be set at any time before calling show().

It is recommended to base 64 encode the custom data!

val rewardedAd: HeliumRewardedAd = // create your HeliumRewardedAd

// load ad

val base64EncodedCustomData = "Y3VzdG9tIGRhdGE="
rewarded.customData = base64EncodedCustomData
// show ad

See: Mediation SDK: Manage Placement's Rewarded Callbacks for configuration setup


Create a HeliumIlrdObserver object and implement its onImpression method. Then, pass the object to the HeliumSdk.subscribe and HeliumSdk.unsubscribe methods.

val ilrdObserver = object: HeliumIlrdObserver {
  override fun onImpression(impData: HeliumImpressionData) {
      // Placement name
      val placement = impData.placementId
      // JSON
      val json = impData.ilrdInfo

override fun onCreate(savedInstanceState: Bundle?) {
  // Subscribe to ILRD on app startup, e.g. in onCreate()

override fun onDestroy() {
  // Unsubscribe from ILRD on app terminations, e.g. in onDestroy()
HeliumIlrdObserver ilrdObserver = new HeliumIlrdObserver() {
    public void onImpression(@NonNull HeliumImpressionData heliumImpressionData) {
        // Placement name
        String placementId = heliumImpressionData.getPlacementId();
        // JSON
        JSONObject json = heliumImpressionData.getIlrdInfo();

protected void onCreate(Bundle savedInstanceState) {
  // Subscribe to ILRD on app startup, e.g. in onCreate()

protected void onDestroy() {
  // Unsubscribe from ILRD on app terminations, e.g. in onDestroy()
