SDK Integration

1. Download the latest Unity SDK from here.

2. Import the TenjinUnityPackage.unitypackage into your project: Assets -> Import Package.

Google Play

By default, unspecified is the default App Store. Update the app store value to googleplay, if you distribute your app on Google Play Store.

Set your App Store Type value to googleplay:

BaseTenjin instance = Tenjin.getInstance("<SDK_KEY>");

instance.SetAppStoreType(AppStoreType.googleplay);

The Tenjin SDK requires the following permissions:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <!-- Required to get network connectivity (i.e. wifi vs. mobile) -->

Google Play Services requires all API level 32 (Android 13) apps using the advertising_id(Android Advertising ID (AAID)) to declare the Google Play Services AD_ID permission (shown below) in their manifest file. You are required to update the tenjin-android-sdk to version 1.12.8 in order to use the below permission.

<uses-permission android:name="com.google.android.gms.permission.AD_ID"/>

Android Advertising ID (AAID) and Install Referrer

Add Android Advertising ID (AAID) and Install Referrer libraries, add it to your build.gradle file.

dependencies {
  implementation 'com.google.android.gms:play-services-ads-identifier:{version}'
  implementation 'com.android.installreferrer:installreferrer:{version}'
}

To be able to collect Meta's Install Referrer, add these queries to your Android Manifest:

<queries>
  <package android:name="com.facebook.katana" />
</queries>

<queries>
  <package android:name="com.instagram.android" />
</queries>

If you haven't set up Facebook's SDK (Meta) yet, add the following to your strings.xml file:

<string name="facebook_app_id" translatable="false">YOUR_APP_ID</string>

Amazon store

By default, unspecified is the default App Store. Update the app store value to amazon, if you distribute your app on Amazon store.

Set your App Store Type value to amazon:

BaseTenjin instance = Tenjin.getInstance("<SDK_KEY>");

instance.SetAppStoreType(AppStoreType.amazon);

OAID and other Android App Stores

Tenjin supports promoting your app on other Android App Stores using the Android OAID. We have the following requirements for integrating OAID libraries. If you plan to release your app outside of Google Play, make sure to implement these OAID libraries.

MSA OAID

MSA OAID is an advertising ID for devices manufactured in China that the MSA (Mobile Security Alliance) provides. For integration with the MSA library, download the following oaid_sdk_1.0.25.aar.

Place the oaid_sdk_1.0.25.aar file in your project's Android libs directory: /Assets/Plugins/Android

Set your App Store Type value to other:

BaseTenjin instance = Tenjin.getInstance("<SDK_KEY>");

instance.SetAppStoreType(AppStoreType.other);

Huawei OAID

For outside of China, you can collect OAID using the library provided by Huawei. For integration with the Huawei OAID library, download the following Huawei AAR file: huawei-ads-identifier.aar. If your app is in the Huawei App Gallery, download and add the Huawei Install Referrer file: huawei-ads-installreferrer.aar.

Place the Huawei files in your project's Android libs directory: /Assets/Plugins/Android

Set your App Store Type value to other:

BaseTenjin instance = Tenjin.getInstance("<SDK_KEY>");

instance.SetAppStoreType(AppStoreType.other);

Proguard Settings

-keep class com.tenjin.** { *; }
-keep public class com.google.android.gms.ads.identifier.** { *; }
-keep public class com.google.android.gms.common.** { *; }
-keep public class com.android.installreferrer.** { *; }
-keep class * extends java.util.ListResourceBundle {
    protected java.lang.Object[][] getContents();
}
-keepattributes *Annotation*

If you are using Huawei libraries, you can to use these settings:

-keep class com.huawei.hms.ads.** { *; }
-keep interface com.huawei.hms.ads.** { *; }

App Initialization

1. Get your SDK_KEY from your app page. Note: SDK_KEY is unique for each of your app. You can create up to 3 keys for the same app.

   

2. In your project's first Start() method, add the following line of code. Also add to OnApplicationPause() if you want to send sessions data when a user resumes using the app from the background.

using UnityEngine;
using System.Collections;

public class TenjinExampleScript : MonoBehaviour {

  void Start() {
    TenjinConnect();
  }

  void OnApplicationPause(bool pauseStatus) {
    if (!pauseStatus) {
      TenjinConnect();
    }
  }

  public void TenjinConnect() {
    BaseTenjin instance = Tenjin.getInstance("<SDK_KEY>");

    // Sends install/open event to Tenjin
    instance.Connect();
  }
}

NOTE: Please ensure you implement this code on every Start() and OnApplicationPause(), not only on the first app open of the app. If we notice that you don't follow our recommendation, we can't give you the proper support or your account might be suspended.

App Store

We support three app store options,

1. googleplay
2. amazon
3. other

By default, unspecified is the default App Store. If you are publishing in a specific App Store, update the app store value to the appropriate app store value. The app store value other is used for Huawei AppGallery and other app stores:

1. AndroidManifest.xml:

<meta-data
    android:name="TENJIN_APP_STORE"
    android:value="{{SET_APP_STORE_TYPE_VALUE}}" />

2. SetAppStoreType():

BaseTenjin instance = Tenjin.getInstance("<SDK_KEY>");

instance.SetAppStoreType(AppStoreType.{{SET_APP_STORE_TYPE_VALUE}});

ATTrackingManager (iOS)

• Starting with iOS 14, you have the option to show the initial ATTrackingManager permissions prompt and selection to opt in/opt out users.

• If the device doesn't accept tracking permission, IDFA will become zero. If the device accepts tracking permission, the Connect() method will send the IDFA to our servers.

• You can also still call Tenjin connect(), without using ATTrackingManager. ATTrackingManager permissions prompt is not obligatory until the early spring of 2021.

using UnityEngine;
using System.Collections;
using UnityEngine.iOS;

public class TenjinExampleScript : MonoBehaviour {

    void Start() {
      TenjinConnect();
    }

    void OnApplicationPause(bool pauseStatus) {
      if (!pauseStatus) {
        TenjinConnect();
      }
    }

    public void TenjinConnect() {
      BaseTenjin instance = Tenjin.getInstance("SDK_KEY");

#if UNITY_IOS
      if (new Version(Device.systemVersion).CompareTo(new Version("14.0")) >= 0) {
        // Tenjin wrapper for requestTrackingAuthorization
        instance.RequestTrackingAuthorizationWithCompletionHandler((status) => {
          Debug.Log("===> App Tracking Transparency Authorization Status: " + status);

          // Sends install/open event to Tenjin
          instance.Connect();

        });
      }
      else {
          instance.Connect();
      }
#elif UNITY_ANDROID

      // Sends install/open event to Tenjin
      instance.Connect();

#endif
    }
}

Displaying an ATT permission prompt

To comply with Apple’s ATT guidelines, you must provide a description for the ATT permission prompt, then implement the permission request in your application.

Note: You must implement the permission request before serving ads in your game.

Configuring a user tracking description

Apple requires a description for the ATT permission prompt. You need to set the description with the NSUserTrackingUsageDescription key in the Info.plist file of your Xcode project. You have to provide a message that informs the user why you are requesting permission to use device tracking data:

• In your Xcode project navigator, open the Info.plist file.
• Click the add button (+) beside any key in the property list editor to create a new property key.
• Enter the key name NSUserTrackingUsageDescription.
• Select a string value type.
• Enter the app tracking transparency message in the value field. Some examples include:
  • "We will use your data to provide a better and personalized ad experience."
  • "We try to show ads for apps and products that will be most interesting to you based on the apps you use, the device you are on, and the country you are in."
  • "We try to show ads for apps and products that will be most interesting to you based on the apps you use."

Note: Apple provides specific app store guidelines that define acceptable use and messaging for all end-user facing privacy-related features. Tenjin does not provide legal advice. Therefore, the information on this page is not a substitute for seeking your own legal counsel to determine the legal requirements of your business and processes, and how to address them.

SKAdNetwork and Conversion Values

As part of SKAdNetwork, we created wrapper method for updatePostbackConversionValue(_:). Our method will register the equivalent SKAdNetwork methods and also send the conversion values to our servers.

updatePostbackConversionValue(_:) 6 bit value should correspond to the in-app event and shouldn't be entered as binary representation but 0-63 integer. Our server will reject any invalid values.

As of iOS 16.1, which supports SKAdNetwork 4.0, you can now send coarseValue (String, with possible variants being "low", "medium" or "high") and lockWindow (Boolean) as parameters on the update postback method:

updatePostbackConversionValue(conversionValue: Integer, coarseValue: String)

updatePostbackConversionValue(conversionValue: Integer, coarseValue: String, lockWindow: Bool)

• For iOS version 16.1+ which supports SKAdNetwork 4.0, you can call this method as many times as you want and can make the conversion value lower or higher than the previous value.

• For iOS versions lower than 16.1 supporting SKAdnetWork versions lower than 4.0, you can call this method and our SDK will automatically detect the iOS version and update conversionValue only.

using UnityEngine;
using System.Collections;

public class TenjinExampleScript : MonoBehaviour {

    void Start() {
      TenjinConnect();
    }

    void OnApplicationPause(bool pauseStatus) {
      if (!pauseStatus) {
        TenjinConnect();
      }
    }

    public void TenjinConnect() {
      BaseTenjin instance = Tenjin.getInstance("SDK_KEY");

#if UNITY_IOS

      // Sends install/open event to Tenjin
      instance.Connect();

      // Sets SKAdNetwork Conversion Value
      // You will need to use a value between 0-63
      instance.updatePostbackConversionValue(<Integer between 0 and 63>);
      
      // For iOS 16.1+ (SKAN 4.0)
      instance.updatePostbackConversionValue(<Integer between 0 and 63>, "medium");
      instance.updatePostbackConversionValue(<Integer between 0 and 63>, "medium", true);

#elif UNITY_ANDROID

      // Sends install/open event to Tenjin
      instance.Connect();

#endif
    }
}

SKAdNetwork and iOS 15+ Advertiser Postbacks

To specify Tenjin as the destination for your SK Ad Network postbacks, do the following:

1. Select Info.plist in the Project navigator in Xcode.
2. Click the Add button (+) beside a key in the property list editor and press Return.
3. Type the key name NSAdvertisingAttributionReportEndpoint.
4. Choose String from the pop-up menu in the Type column.
5. Enter https://tenjin-skan.com

These steps are adapted from Apple's instructions at https://developer.apple.com/documentation/storekit/skadnetwork/configuring_an_advertised_app.

GDPR

As part of GDPR compliance, with Tenjin's SDK you can opt-in, opt-out devices/users, or select which specific device-related params to opt-in or opt-out. OptOut() will not send any API requests to Tenjin, and we will not process any events.

To opt-in/opt-out:

void Start () {

  BaseTenjin instance = Tenjin.getInstance("SDK_KEY");

  boolean userOptIn = CheckOptInValue();

  if (userOptIn) {
    instance.OptIn();
  }
  else {
    instance.OptOut();
  }

  instance.Connect();
}

boolean CheckOptInValue()
{
  // check opt-in value
  // return true; // if user opted-in
  return false;
}

• To opt-in/opt-out specific device-related parameters, you can use the OptInParams() or OptOutParams().

• OptInParams() will only send device-related parameters that are specified. OptOutParams() will send all device-related parameters except ones that are specified.

• Kindly note that we require the following parameters to properly track devices in Tenjin's system. If one of these mandatory parameters is missing, the event will not be processed or recorded.

  • For Android,
    • advertising_id
  • For iOS
    • developer_device_id

• If you are targeting IMEI and/or OAID Ad Networks for Android, add:

  • imei
  • oaid

• If you intend to use Google Ad Words, you will also need to add:

  • platform
  • os_version
  • app_version
  • locale
  • device_model
  • build_id

If you want to only get specific device-related parameters, use OptInParams(). In example below, we will only these device-related parameters: ip_address, advertising_id, developer_device_id, limit_ad_tracking, referrer, and iad:

BaseTenjin instance = Tenjin.getInstance("SDK_KEY");

List<string> optInParams = new List<string> {"ip_address", "advertising_id", "developer_device_id", "limit_ad_tracking", "referrer", "iad"};
instance.OptInParams(optInParams);

instance.Connect();

If you want to send ALL parameters except specific device-related parameters, use OptOutParams(). In the example below, we will send ALL device-related parameters except: locale, timezone, and build_id parameters.

BaseTenjin instance = Tenjin.getInstance("SDK_KEY");

List<string> optOutParams = new List<string> {"locale", "timezone", "build_id"};
instance.OptOutParams(optOutParams);

instance.Connect();

Opt in/out using CMP

You can automatically opt in or opt out using your CMP consents (purpose 1) which are already saved in the user's device. The method returns a boolean to let you know if it's opted in or out.

OptInOutUsingCMP()

BaseTenjin instance = Tenjin.getInstance("<SDK_KEY>");
optInOut = instance.OptInOutUsingCMP(); 

Device-Related Parameters

Purchase Events

iOS IAP Validation

iOS receipt validation requires transactionId and receipt (signature will be set to null). For receipt, be sure to send the receipt Payload(the base64 encoded ASN.1 receipt) from Unity.

IMPORTANT: If you have subscription IAP, you will need to add your app's public key in the Tenjin dashboard. You can retrieve your iOS App-Specific Shared Secret from the iTunes Connect Console > Select your app > App Information > App-Specific Shared Secret.

Android IAP Validation

Google Play App Store

Google Play receipt validation requires receipt and signature are required (transactionId is set to null).

IMPORTANT: You will need to add your app's public key in the Tenjin dashboard (under the app 'edit' page). You can retrieve your Base64-encoded RSA public key from the Google Play Developer Console > Select your app > Monetize > Monetization setup > Google Play Billing > Licensing: Base64-encoded RSA public key. Please note that for Android, we currently only support IAP transactions from Google Play.

Amazon AppStore

Amazon AppStore receipt validation requires receiptId and userId parameters.

IMPORTANT: You will need to add your Amazon app's Shared Key in the Tenjin dashboard. The shared secret can be found on the Shared Key in your developer account with the Amazon Appstore account

iOS and Android IAP Example

In the example below, we are using the widely used MiniJSON library for JSON deserializing.

  public static void OnProcessPurchase(PurchaseEventArgs purchaseEventArgs) {
    var price = purchaseEventArgs.purchasedProduct.metadata.localizedPrice;
    double lPrice = decimal.ToDouble(price);
    var currencyCode = purchaseEventArgs.purchasedProduct.metadata.isoCurrencyCode;

    var wrapper = Json.Deserialize(purchaseEventArgs.purchasedProduct.receipt) as Dictionary<string, object>;  // https://gist.github.com/darktable/1411710
    if (null == wrapper) {
        return;
    }

    var store     = (string)wrapper["Store"]; // GooglePlay, AmazonAppStore, AppleAppStore, etc.
    var payload   = (string)wrapper["Payload"]; // For Apple this will be the base64 encoded ASN.1 receipt. For Android, it is the raw JSON receipt.
    var productId = purchaseEventArgs.purchasedProduct.definition.id;

#if UNITY_ANDROID

  if (store.Equals("GooglePlay")) {
    var googleDetails = Json.Deserialize(payload) as Dictionary<string, object>;
    var googleJson    = (string)googleDetails["json"];
    var googleSig     = (string)googleDetails["signature"];

    CompletedAndroidPurchase(productId, currencyCode, 1, lPrice, googleJson, googleSig);
  }

  if (store.Equals("AmazonApps")) {
    var amazonDetails   = Json.Deserialize(payload) as Dictionary<string, object>;
    var amazonReceiptId = (string)amazonDetails["receiptId"];
    var amazonUserId    = (string)amazonDetails["userId"];

    CompletedAmazonPurchase(productId, currencyCode, 1, lPrice, amazonReceiptId, amazonUserId);
  }

#elif UNITY_IOS

  var transactionId = purchaseEventArgs.purchasedProduct.transactionID;

  CompletedIosPurchase(productId, currencyCode, 1, lPrice , transactionId, payload);

#endif

  }

  private static void CompletedAndroidPurchase(string ProductId, string CurrencyCode, int Quantity, double UnitPrice, string Receipt, string Signature)
  {
    BaseTenjin instance = Tenjin.getInstance("SDK_KEY");
    instance.Transaction(ProductId, CurrencyCode, Quantity, UnitPrice, null, Receipt, Signature);
  }

  private static void CompletedIosPurchase(string ProductId, string CurrencyCode, int Quantity, double UnitPrice, string TransactionId, string Receipt)
  {
    BaseTenjin instance = Tenjin.getInstance("SDK_KEY");
    instance.Transaction(ProductId, CurrencyCode, Quantity, UnitPrice, TransactionId, Receipt, null);
  }

  private static void CompletedAmazonPurchase(string ProductId, string CurrencyCode, int Quantity, double UnitPrice, string ReceiptId, string UserId)
  {
    BaseTenjin instance = Tenjin.getInstance("SDK_KEY");
    instance.TransactionAndroid(ProductId, CurrencyCode, Quantity, UnitPrice, ReceiptId, UserId);
  }

Disclaimer: If you are implementing purchase events on Tenjin for the first time, make sure to verify the data with other tools you’re using before you start scaling up your user acquisition campaigns using purchase data.

Subscription IAP

• You are responsible to send a subscription transaction one time during each subscription interval (i.e., For example, for a monthly subscription, you will need to send us 1 transaction per month). In the example timeline below, a transaction event should only be sent at the "First Charge" and "Renewal" events. During the trial period, do not send Tenjin the transaction event.

  

• Tenjin does not de-dupe duplicate transactions.

• If you have iOS subscription IAP, you will need to add your app's public key in the Tenjin dashboard. You can retrieve your iOS App-Specific Shared Secret from the iTunes Connect Console > Select your app > Features > In-App Purchases > App-Specific Shared Secret.

• For more information on iOS subscriptions, please see: Apple documentation on Working with Subscriptions

• For more information on Android subscriptions, please see: Google Play Billing subscriptions documentation

Custom Events

IMPORTANT: Limit custom event names to less than 80 characters. Do not exceed 500 unique custom event names.

• Include the Assets folder in your Unity project
• In your projects' method for the custom event, write the following for a named event: Tenjin.getInstance("<SDK_KEY>").SendEvent("name") and the following for a named event with an integer value: Tenjin.getInstance("<SDK_KEY>").SendEvent("nameWithValue","value")
• Make sure value passed is an integer. If value is not an integer, your event will not be passed.

Here's an example of the code:

void MethodWithCustomEvent(){
    //event with name
    BaseTenjin instance = Tenjin.getInstance ("SDK_KEY");
    instance.SendEvent("name");

    //event with name and integer value
    instance.SendEvent("nameWithValue", "value");
}

.SendEvent("name") is for events that are static markers or milestones. This would include things like tutorial_complete, registration, or level_1.

.SendEvent("name", "value") is for events that you want to do math on a property of that event. For example, ("coins_purchased", "100") will let you analyze a sum or average of the coins that are purchased for that event.

Server-to-server integration

Tenjin offers server-to-server integration. This allows you to send your install and post-install events directly from your servers to Tenjin servers without needing an SDK integration. If you want to access to the documentation, please send email to support@tenjin.com.

App Subversion parameter for A/B Testing (requires DataVault)

If you are running A/B tests and want to report the differences, we can append a numeric value to your app version using the AppendAppSubversion() method. For example, if your app version 1.0.1, and set AppendAppSubversion(8888), it will report app version as 1.0.1.8888.

This data will appear within DataVault, where you will be able to run reports using the app subversion values.

BaseTenjin instance = Tenjin.getInstance("<API KEY>");
instance.AppendAppSubversion(8888);
instance.Connect();

LiveOps Campaigns

Tenjin supports retrieving of user attribution information, like sourcing ad network and campaign, from the SDK. This will allow developers to collect and analyze user-level attribution data in real-time. Here are the possible use cases using Tenjin LiveOps Campaigns:

• If you have your own data anlytics tool, custom callback will allow you to tie the attribution data to your in-game data per device level.
• Show different app content depending on where the user comes from. For example, if user A is attributed to organic and user B is attributed to Facebook and user B is likely to be more engaged with your app, then you want to show a special in-game offer after the user installs the app. If you want to discuss more specific use cases, please write to support@tenjin.com.

Customer User ID

You can set and get customer user id to send as a parameter on events.

.SetCustomerUserId("user_id")

.GetCustomerUserId()

BaseTenjin instance = Tenjin.getInstance("<SDK_KEY>");
instance.SetCustomerUserId("user_id");
string userId = instance.GetCustomerUserId(); 

Analytics Installation ID

You can get the analytics id which is generated randomly and saved in the local storage of the device.
GetAnalyticsInstallationId()

BaseTenjin instance = Tenjin.getInstance("<SDK_KEY>");
analyticsId = instance.GetAnalyticsInstallationId; 

Retry/cache events and IAP

You can enable/disable retrying and caching events and IAP when requests fail or users don't have internet connection. These events will be sent after a new event has been added to the queue and user has recovered connection.

.SetCacheEventSetting(true)

BaseTenjin instance = Tenjin.getInstance("<SDK_KEY>");
instance.SetCacheEventSetting(true); 

Google DMA Parameters

If you already have a CMP integrated, Google DMA parameters will be automatically collected by the Tenjin SDK. There’s nothing to implement in the Tenjin SDK if you have a CMP integrated. If you want to override your CMP, or simply want to build your own consent mechanisms, you can use the following:

SetGoogleDMAParameters(bool, bool)

BaseTenjin instance = Tenjin.getInstance("<SDK_KEY>");
instance.SetGoogleDMAParameters(adPersonalization, adUserData); 

To explicitly manage the collection of Google DMA parameters, you have the flexibility to opt in or opt out at any time. While the default setting is to opt in, you can easily adjust your preferences using the OptInGoogleDMA or OptOutGoogleDMA methods, ensuring full control over your data privacy settings:

instance.OptInGoogleDMA(); 
instance.OptOutGoogleDMA(); 

Impression Level Ad Revenue Integration

Tenjin supports the ability to integrate with the Impression Level Ad Revenue (ILRD) feature from,

• AppLovin
• Unity LevelPlay
• HyperBid
• AdMob
• TopOn
• CAS
• TradPlus

This feature allows you to receive events which correspond to your ad revenue which is affected by each advertisement shown to a user. To enable this feature, follow the below instructions.

Testing

You can verify if the integration is working correctly with our Live Test Device Data Tool. Add your advertising_id or IDFA/GAID to the list of test devices. You can find this under Support -> Test Devices. Go to the SDK Live page and send the test events from your app. You should see live events come in:
