Unity plugin V6 integration guide for developers – Help Center

At a glance: Integrate AppsFlyer SDK into iOS/Android games developed with Unity to measure installs, in-app events, media sources, and more.

Unity V6 support for iOS 14

The Unity plugin V6 includes support for iOS 14 and has significant API method changes from previous versions. Migrating to Unity V6 from a previous version causes breaking changes. These changes include new APIs, different classes and package names, and the removal of: com.appsflyer.GetDeepLinkingActivity

To update your plugin from an earlier (V5) version, see our guide on migrating to the V6 beta (requires updating the Unity package).

Note

Unity plugin V4 is deprecated. The V4 integration guide is available for download in PDF format (link below).

Unity plugin V6

The Unity plugin V6 enables the development of iOS and Android apps using the Unity real-time platform. Based on the AppsFlyer mobile SDKs, it implements the same methods and supports the equivalent functionality of the platform-specific (iOS and Android) SDKs. The plugin is open-source and available on GitHub. In this article, the terms plugin and SDK are used interchangeably.

1. Overview—Unity V6

Mobile apps developed on the Unity platform use a common AppsFlyer plugin for both the Android and iOS platforms.

Action list to integrate the Unity plugin into your apps
Tab	Content	Result
[Mandatory] Integration	Add and configure the plugin	App dashboard shows: New organic install New non-organic install
[Recommended] Core APIs	Use the plugin core APIs to: Measure in-app events Measure revenue Perform deep linking Gather conversion data	App dashboard shows: In-app events Revenue Ready to: Perform deep linking
Additional APIs	Implement and use optional APIs for: Uninstall measurements Referrals (user invite attribution) Push notifications	Ready to: Measure uninstalls Referrals User engagements with push notifications Handle user privacy scenarios and more.
API reference	Quick SDK API reference for developers

After you implement and initialize the plugin, the marketer/advertiser will be able to see two installs in the app Overview dashboard—one organic, one non-organic.

2. Add the plugin to your app

Important!

AppsFlyer Unity SDK doesn't support Unity Internal Build System.

2.1 Download the AppsFlyer Unity plugin

Download the latest Unity plugin from GitHub.

2.2 Install the plugin

The External Dependency Manager for Unity (EDM4U) is distributed with the AppsFlyer Unity plugin by default. This eases the integration process by resolving dependency conflicts between your plugin and other plugins in your project.

To install the plugin:

Add appsflyer-unity-plugin.v*.unitypackage to automatically import all the assets required for both the AppsFlyer plugin and the EDM4U.

To install the plugin without the EDM4U:

Import appsflyer-unity-plugin.v*.unitypackage to your project, but make sure to clear the selection of EDM4U dependencies.
Download and add the required Android dependencies to the Assets/Plugins/Android folder:
Download and add the required iOS dependencies to the Assets/Plugins/iOS/AppsFlyer folder:
- iOS SDK as a static library

2.3 Set up Android

To set up the required Android permissions:

Set the following permissions in AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

3. Initialize the plugin

This section describes how to implement and initialize the plugin.

3.1 Retrieve the dev key

The key is unique and identifies the account. It some cases there is an app-level key.
Dev key is mandatory.

To get the dev key:

In AppsFlyer, go to Configuration > App Settings.
Get the dev key.

3.2 Initialize the plugin

To initialize the plugin using the prefab:

Go to Assets > AppsFlyer.
Drag AppsFlyerObject.prefab to your scene.

Set the following fields:

Setting	Remarks
Dev key	Paste the dev key that you retrieved previously.
App ID	iOS: Enter the iOS app ID (no `id` prefix). Android: Leave blank.
Get conversion data	If the app implements AppsFlyer deep linking, set to "True". The default is "False', meaning deep linking by default is NOT implemented.
Is debug	To view debug logs during development: Set to true. Note: Ensure to disable (set to false) before releasing the app to production.

Update the code in Assets > AppsFlyer > AppsFlyerObjectScript.cs with other available APIs.

To integrate manually:

Create a game object and add the following init code:

using AppsFlyerSDK;

public class AppsFlyerObjectScript : MonoBehaviour , IAppsFlyerConversionData
{
    void Start()
    {
        /* AppsFlyer.setDebugLog(true); */
        AppsFlyer.initSDK("devkey", "appID", this);
        AppsFlyer.startSDK();
    }

    public void onConversionDataSuccess(string conversionData)
    {
        AppsFlyer.AFLog("onConversionDataSuccess", conversionData);
        Dictionary<string, object> conversionDataDictionary = AppsFlyer.CallbackStringToDictionary(conversionData);
        // add deferred deeplink logic here
    }

    public void onConversionDataFail(string error)
    {
        AppsFlyer.AFLog("onConversionDataFail", error);
    }

    public void onAppOpenAttribution(string attributionData)
    {
        AppsFlyer.AFLog("onAppOpenAttribution", attributionData);
        Dictionary<string, object> attributionDataDictionary = AppsFlyer.CallbackStringToDictionary(attributionData);
        // add direct deeplink logic here
    }

    public void onAppOpenAttributionFailure(string error)
    {
        AppsFlyer.AFLog("onAppOpenAttributionFailure", error);
    }
}

Note: Make sure not to call destroy on the game object.

4. Test installs

4.1 Allowlist the test device

Allowlist the test device.

4.2 Simulate installs

Simulate organic and non-organic installs.

Simulate an organic install

Organic installs are unattributed installs; they are usually the result of installs made directly via app stores. To simulate an organic install, follow these instructions.

Simulate a non-organic install

Non-organic installs are attributed installs; they are usually the result of an ad engagement. To simulate a non-organic install, follow these instructions.

Recording in-app events and revenue measures the quality of your app users, while deep linking allows you to give app users a better user experience.

In this tab, app developers find relevant instructions. However, app owner/marketer input is essential. The app owner:

Decides the in-app events required to record and measure user quality.
Needs to access the AppsFlyer platform to set up OneLink for deep linking.

5. Record in-app events

Record in-app events to measure KPIs such as revenue, ROI, and LTV (Lifetime Value).

In-app events should be implemented to record user events. Events can be sent in several ways:

[Best practice] Sending events via the app as described in this article.
For additional methods see in-app events overview guide.

For apps that belong to a vertical, for example, travel, gaming, eCommerce, see the list of recommended in-app events per vertical.

5.1 In-app event names and parameters

To send events:

Specify the event name and parameters.
See related lists:
- List of recommended event names and structures
- List found in AFInAppEvents class.

[Best practice] Use event names and parameters for the following reasons:

Standard naming: AppsFlyer can automatically map events to SRNs such as Facebook, Google, and Twitter.
Backward compatibility: No issue arises if AppsFlyer changes an event name or parameter. The implementation is backward compatible.

5.2 Record revenue

Report revenue by adding the af_revenue parameter to in-app events.

Populate af_revenue with numeric values. Negative values are permitted.
The af_revenueparameter populates AppsFlyer revenue counters and raw data fields. Doing so enables marketers to view revenue in the dashboard.
Revenue can be sent using other parameters, but the AppsFlyer platform won't recognize it as revenue. Click here for more details.
Revenue values must not contain comma separators, currency symbols, or text.
Example revenue event: 1234.56

Best practice: Learn about currency settings, display, and currency conversion.

Currency code requirements when sending revenue events

Default currency: USD
Use a 3-character ISO 4217 code (an example follows).
Set the currency code by calling the API:
```
AppsFlyer.setCurrencyCode("ZZZ")
```

Example: In-app purchase event with revenue

This purchase event is for 200.12 Euros. For the revenue to reflect in the dashboard use the following.

System.Collections.Generic.Dictionary<string, string> purchaseEvent = new 
System.Collections.Generic.Dictionary<string, string> ();
purchaseEvent.Add(AFInAppEvents.CURRENCY, "EUR");
purchaseEvent.Add(AFInAppEvents.REVENUE, "200.12");
purchaseEvent.Add(AFInAppEvents.QUANTITY, "1");
purchaseEvent.Add(AFInAppEvents.CONTENT_TYPE, "category_a",);
AppsFlyer.sendEvent ("af_purchase", purchaseEvent);

Record negative revenue

Record negative revenue using a minus sign.

Revenue value is preceded by a minus sign.
The event name has a unique value, "cancel_purchase". This lets you identify negative revenue events in raw data reports and in the Dashboard.

Example: App user receives a refund or cancels a subscription.

System.Collections.Generic.Dictionary<string, string> purchaseEvent = new 
System.Collections.Generic.Dictionary<string, string> ();
purchaseEvent.Add(AFInAppEvents.CURRENCY, "USD");
purchaseEvent.Add(AFInAppEvents.REVENUE, "-200");
purchaseEvent.Add(AFInAppEvents.QUANTITY, "1");
purchaseEvent.Add(AFInAppEvents.CONTENT_TYPE, "category_a");
AppsFlyer.sendEvent ("cancel_purchase", purchaseEvent);

5.3 In-app purchase validation

The plugin provides server verification for in-app purchases.

To validate a purchase, operating system specific instructions:

#if UNITY_ANDROID && !UNITY_EDITOR
 AppsFlyerAndroid.validateAndSendInAppPurchase(
 "publicKey", 
 "signature", 
 "purchaseData", 
 "price", 
 "currency", 
 null, 
 this);
#endif

Ensure you test against the Apple sandbox server call:

#if UNITY_IOS && !UNITY_EDITOR
 AppsFlyeriOS.validateAndSendInAppPurchase(
 "productIdentifier", 
 "price", 
 "currency", 
 "tranactionId", 
 null, 
 this);
#endif

Method parameters

Parameter	Description
String publicKey	Public key from Google Developer Console
String signature	Transaction signature; returned by Google API when a purchase is completed
String purchaseData	Product purchased in JSON format; returned by Google API when a purchase is completed
String revenue	In-app event revenue to be reported to AppsFlyer
String currency	In-app event currency to be reported to AppsFlyer
Dictionary<String, String> additionalParameters	Additional in-app event parameters which appear in the event_value field in in-app event raw data

Parameter	Description
String productIdentifier	Product identifier
String price	In-app event revenue to be reported to AppsFlyer
String currency	In-app event currency to be reported to AppsFlyer
Dictionary<String, String> additionalParameters	Additional in-app event parameters which appear in the event_value field in in-app event raw data

Note

Call validateReceipt to automatically generate an af_purchase in-app event.

Don't send a purchase event after validating the purchase. Doing so results in duplicate event reporting.

5.4 In-app event considerations

Event name: maximum 45 characters
Event value: must not exceed 1000 characters - if longer we can truncate it
Supports non-English characters for in-app events (and other APIs)
Pricing and revenue:
- Only use numbers and decimals such as 5 or 5.2
- Up to 5 numbers after the decimal are permitted. For example, 5.12345

5.5 Examples of recording in-app events

Record in-app events by calling sendEvent and include the event name and value parameters.
See In-app events for more details.

Example: How to record an in-app purchase event

For a comprehensive list of ready-made code snippets per vertical, see our guide for rich in-app events per verticals.

System.Collections.Generic.Dictionary<string, string> purchaseEvent = new 
System.Collections.Generic.Dictionary<string, string> ();
purchaseEvent.Add(AFInAppEvents.CURRENCY, "USD");
purchaseEvent.Add(AFInAppEvents.REVENUE, "200");
purchaseEvent.Add(AFInAppEvents.QUANTITY, "2");
purchaseEvent.Add(AFInAppEvents.CONTENT_TYPE, "category_a");
purchaseEvent.Add(AFInAppEvents.CONTENT_ID, "092");
AppsFlyer.sendEvent (AFInAppEvents.PURCHASE, purchaseEvent);

5.6 Record offline in-app events

Sometimes users generate in-app events, while they have no internet connection. AppsFlyer caches the event and reports when possible.

The plugin sends events to AppsFlyer servers and waits for a response.
If the plugin doesn’t get a 200 response, the event is stored in the cache.
After receiving the next 200 response, the cached event is re-sent to the server.
If the cache holds multiple events, they are sent to the server one after the other.

Note

The cache can store up to 40 events.

Only the first 40 offline events are saved.
All following offline events, up until the next 200 response, are discarded.
In the raw data report,
- Event time = when an event was sent to AppsFlyer after the device is back online.
- It is not the time when the event took place.

6. Deep-link with OneLink

AppsFlyer OneLink is the solution for multi-platform attribution: redirection and deep linking.

6.1 Device detection and redirection

OneLink:

Detects the device type (Android and iOS, desktop, etc.) when a user clicks, then
Redirects the user to the correct destination: Google Play, iOS app store, out-of-store markets, or web pages.

To implement multi-platform attribution links and review the basics of deep linking, see the OneLink redirection guide.

6.2 Deep linking

Use deep linking to direct existing users to specific activities and customized content.

An app owner and a developer must work together to set up deep linking with OneLink:

App owner must access the AppsFlyer dashboard
Developer must access the app

See setting up deep linking with OneLink.

6.3 Deferred deep linking

Deferred deep linking lets you deep link new users to direct them to specific activities and customized content with the first launch after an app install.

Standard deep linking also directs users to specific activities and customized content, but an app must already be installed on the user's device.

To set up deferred deep linking with OneLink:

Developer needs access to the AppsFlyer platform.
AppsFlyer platform setup for deferred and standard deep linking is the same.
Must implement additional logic in the app to deep link users and provide them with customized content after they install and launch the app.

Check deferred deep linking for more information.

6.4 Get deep link data

The plugin provides conversion or engagement data after every install or deep-linking event. Use this data to customize content or the app's programmatic behavior.

To receive deep link data:

Implement callback onAppOpenAttribution(found inIAppsFlyerConversionDataclass); it is called by the AppsFlyer plugin.
Returned OneLink/attribution link parameters trigger an app to open.
Parse the values and apply the logic to trigger the relevant app page.

public void onAppOpenAttribution(string attributionData)
 {
 AppsFlyer.AFLog("onAppOpenAttribution", attributionData);
 Dictionary<string, object> attributionDataDictionary = AppsFlyer.CallbackStringToDictionary(attributionData);
 // add direct deeplink logic here
 }

Check deep linking data for more information.

7. Get conversion data

Access to real-time user attribution data is available for each install. Use this to enhances user engagement by providing:

Personalized content
Sending users to specific activities within an app. See deferred deep linking in this article.

To obtain AppsFlyer conversion data:

Implement the IAppsFlyerConversionDatabase.
Call the initSDK method with this as the last parameter.
Use the onConversionDataSuccess method to redirect the user.

See API reference for onConversionDataSuccess.

using AppsFlyerSDK;

public class AppsFlyerObjectScript : MonoBehaviour , IAppsFlyerConversionData
{
    void Start()
    {
        /* AppsFlyer.setDebugLog(true); */
        AppsFlyer.initSDK("devkey", "appID", this);
        AppsFlyer.startSDK();
    }

    public void onConversionDataSuccess(string conversionData)
    {
        AppsFlyer.AFLog("onConversionDataSuccess", conversionData);
        Dictionary<string, object> conversionDataDictionary = AppsFlyer.CallbackStringToDictionary(conversionData);
        // add deferred deeplink logic here
    }

    public void onConversionDataFail(string error)
    {
        AppsFlyer.AFLog("onConversionDataFail", error);
    }

    public void onAppOpenAttribution(string attributionData)
    {
        AppsFlyer.AFLog("onAppOpenAttribution", attributionData);
        Dictionary<string, object> attributionDataDictionary = AppsFlyer.CallbackStringToDictionary(attributionData);
        // add direct deeplink logic here
    }

    public void onAppOpenAttributionFailure(string error)
    {
        AppsFlyer.AFLog("onAppOpenAttributionFailure", error);
    }
}

8. Attribution

Measure uninstalls

Measure the uninstall rate of users coming from different sources.

To set up uninstall measurement, see the relevant operating system instructions.

Download the Unity Firebase SDK from https://firebase.google.com/docs/unity/setup.
Import FirebaseMessaging.unitypackage into the project.
Import google-services.json into the project (obtained from the Firebase console)

Note

Unity Firebase SDK automatically adds manifest receivers.
Add this code to the Unity class handling the AppsFlyer code:
```
using Firebase.Messaging;
using Firebase.Unity;
```

Add to Start() method:

Firebase.Messaging.FirebaseMessaging.TokenReceived += OnTokenReceived;

Add this method:

public void OnTokenReceived(object sender, Firebase.Messaging.TokenReceivedEventArgs token)
 {
#if UNITY_ANDROID
 AppsFlyerAndroid.updateServerUninstallToken(token.Token);
#endif
 }

Android uninstall guide

Warning

Scenario: Implementing the Unity Firebase SDK.

Requirement: Do not add the following method call to enableUninstallTracking(“SenderID”) if you added the Firebase Unity SDK to your project.

Consequences if added:

Firebase Unity SDK will get the sender ID from the google-services.json file (that was added earlier).
As a result, this may cause a debug warning from Android.

Get your device token from UnityEngine.iOS.NotificationServices.deviceToken.

Call this method when you receive your device token (tab content issues):

AppsFlyer.registerUninstall("device_push_notification_token");

Example:

using AppsFlyerSDK;

public class AppsFlyerObjectScript : MonoBehaviour, IAppsFlyerConversionData
{
    private bool tokenSent;

    void Start()
    {
        AppsFlyer.initSDK("devKey", "appID", this);
        AppsFlyer.startSDK();

#if UNITY_IOS
        UnityEngine.iOS.NotificationServices.RegisterForNotifications(UnityEngine.iOS.NotificationType.Alert | UnityEngine.iOS.NotificationType.Badge | UnityEngine.iOS.NotificationType.Sound);
#endif

    }

    void Update()
    {
#if UNITY_IOS
        if (!tokenSent)
        { 
            byte[] token = UnityEngine.iOS.NotificationServices.deviceToken;
            if (token != null)
            {
                AppsFlyeriOS.registerUninstall(token);
                tokenSent = true;
            }
        }
#endif
    }
}

For more details, see iOS Uninstall Guide

Set additional custom data

To integrate on the plugin level with several external partner platforms (including Segment, Adobe, and Urban Airship), it is necessary to use the setAdditionalData API.

Only use this API if the partner integration article states explicitly the setAdditionalData API is required.

Example: setAdditionalData code

Dictionary<string, string> CustomDataMap = new Dictionary<string, string>();
CustomDataMap.Add("custom_param_1", "value_of_param_1");
AppsFlyer.setAdditionalData(CustomDataMap);

9. Sessions

Custom time between sessions

By default, at least 5 seconds must pass between two app launches for them to count as two separate sessions. To set the minimum time between sessions:

AppsFlyer.setMinTimeBetweenSessions(custom_time_ins_seconds);

Note! If you set a high value for the custom time between launches, this can negatively impact APIs that rely on session data (such as deep linking).

See more about counting app sessions.

Background sessions for utility apps

Not available in Unity.

10. Owned media

Resolve wrapped deep-link URLs

Some 3rd party services (such as email service providers):

Wrap links in emails using their own click recording domains.
Allow you to set your own click-recording domains.

If OneLink is wrapped in such domains, it may limit its functionality. To overcome this:

Call the setResolveDeepLinkURLs API before SDK initialization.
The API gets the OneLink from click domains that launch the app.

Scenario: The click domains redirect to your OneLink at https://mysubdomain.onelink.me/abCD.

Solution:

Use the setResolveDeepLinkURLs API to get the OneLink that is reached after click domains redirect an app user.
This API method receives a list of domains that are resolved by the plugin.
The following code lets you use your click domain but, also, preserve OneLink functionality:
Example
```
AppsFlyer.setResolveDeepLinkURLs("example.com", "click.example.com");
```

Now, use the data from this OneLink to deep-link and customize user content.

Record push notifications

Record push notifications as part of retargeting campaigns.

To record push notifications:

Call the sendPushNotificationData method.
This method is inside the onCreate method of every activity that is launched after clicking this notification:

#if UNITY_ANDROID && !UNITY_EDITOR
 AppsFlyerAndroid.handlePushNotifications();
#endif

For more information, read about push notification measurement.

User invite attribution

If existing app users invite their friends and contacts to become new users, this can be a source of growth.

Attribute and record installs originating from user invites within the app. User invite attribution.

Cross-promotion attribution

Cross-promoting apps can cand drive additional app installs.

Attribute and record installs originating from a cross-promotion campaign: promote one of your apps from within another of your apps already launched by one of your users. Cross-promotion attribution.

11. User identifiers

Get AppsFlyer ID

An AppsFlyer ID is created for each new app install. Use the AppsFlyer ID to:

Send server-to-server in-app events.
Match it to user records in your back-end systems.
Map entries when merging data from pull and push API.

To obtain the unique AppsFlyer ID:

string AppsFlyerUID = AppsFlyer.getAppsFlyerId();

Set customer user ID

Set your own unique customer user ID (CUID) and cross-reference it with the unique AppsFlyer ID.

Unique CUID:

Appear in AppsFlyer raw data CSV reports.
Can be used in postback APIs to cross-reference with internal IDs.

To set the CUID, use:

AppsFlyer.setCustomerUserId("someId");

Good practice! Set the CUID early in the app flow—it is only associated with events reported after its setup.

Call setCustomerUserId before calling startSDK

Recorded events will be associated with the CUID.
Related data will appear in the raw data reports for installs and events.

AppsFlyer.setCustomerUserId("someId");

Get Customer User ID

Check CUID for more information.

Delay plugin init for customerUserID

Set the customer user ID (CUID) and only then initialize the plugin. This is useful if you want your install and event data to contain your CUID.

See the relevant operating system instructions:

Android
iOS

Warning

Only delay setting the CUID if it suits your business logic. If you delay setting the CUID, this can increase the chance for discrepancies and may expose your app to fraud attempts.

Collect OAID

OAID is one of the unique device identifiers that enable attribution.

To collect OAID:

OAID is collected automatically by default. To opt-out, call AppsFlyerAndroid.setCollectOaid(false);.

Download the AAR provided by the MSA alliance.
Add the downloaded aar to the Assets/Plugins/Android folder.
For Huawei devices, add the hms-ads-identifier lib to the Assets/Plugins/Android folder.
Add appsflyer-oaid to your project. This can be done by adding the aar to the Assets/Plugins/Android folder or by adding the following to Assets/AppsFlyer/Editor/AppsFlyerDependencies.xml:

    <androidPackage spec="com.appsflyer:oaid:5.2.0">
    </androidPackage>

12. User privacy

Opt-out

Different scenarios, such as legal and privacy compliance issues, may lead to a decision to opt-out and stop all recording (tracking)

Best practice! Follow the exact instructions for the scenario relevant to your app.

To stop tracking:

Call stopSDK and set to true.
```
AppsFlyer.stopSDK(true);
```
Plugin stops functioning and no longer communicates with AppsFlyer servers.

To reactivate tracking: Call stopSDK and set to false.

Caution

Use the stopSDK API if you want to completely stop tracking a specific app user. Using the API severely impacts attribution, data collection, and the deep linking mechanism.

Anonymize user data

Anonymize specific user identifiers within AppsFlyer analytics to comply with privacy regulations and Facebook data and privacy policies.

To anonymize an app user:

Set the API during SDK initialization
Call anonymizeUserand set to true.
```
AppsFlyer.anonymizeUser(true);
```
App user installs, events, and sessions are anonymized.

To restart tracking: Call anonymizeUser and set to false.

Warning

Anonymizing users severely impacts your attribution information. Only use this option for regions that legally prevent you from collecting user information.

Exclude partners from getting data

In some cases, advertisers may want to stop sharing user-level data with ad networks/partners for specific users. Reasons for this include:

Privacy policies such as CCPA or GDPR
User opt-out mechanisms
Competition with some partners (ad networks, 3rd parties)

AppsFlyer provides two API methods to stop sharing data with some or all partners:

setSharingFilter: Used by advertisers to set some (one or more) networks/integrated partners to exclude from getting data.
setSharingFilterForAllPartners: Used by advertisers to exclude all networks/integrated partners from getting data.

These filtering methods are supported as of SDK V5.4.1.

The filtering method must be called every time the SDK is initialized and affects the whole session. If it takes time to determine whether you must set the sharing filters, then delay the SDK initialization.

When the method is activated before the first startSDK call:

Users from SRNs are attributed as Organic, and their data is not shared with integrated partners.
Users from click ad networks (non-SRNs) are attributed correctly in AppsFlyer, but not shared with the ad networks via postbacks, APIs, raw data reports, or by any other method.

Currently, uninstall data can't be filtered using these methods. However, you can stop sending Uninstall events to partners using their setup pages in AppsFlyer.
