AppsFlyer

Step-by-step guide to send event data from RudderStack to AppsFlyer

AppsFlyer is an industry-leading mobile attribution and marketing analytics platform, provided as a Software-as-a-Service (SaaS). It offers intuitive dashboards, real-time data reports, and a unique deep linking technology to understand your customers better.

RudderStack supports AppsFlyer as a destination to which you can seamlessly send your customer data.

Find the open-source transformer code for this destination in our GitHub repository.

Getting started

Before configuring AppsFlyer as a destination in RudderStack, verify if the source platform is supported by AppsFlyer by referring to the table below:

Connection Mode	Web	Mobile	Server
Device mode	-	Supported	-
Cloud mode	Supported	Supported	Supported

To know more about the difference between the cloud mode and device mode in RudderStack, refer to the RudderStack Connection Modes guide.

We recommend using the the cloud mode to send events to AppsFlyer in the following scenarios:

If you want to use RudderStack's Transformations feature
If you want to send server-side events

Once you have confirmed that the platform supports sending events to AppsFlyer, perform the steps below:

From your RudderStack dashboard, add the source. From the list of destinations, select AppsFlyer.

Refer to the Adding a Source and Destination in RudderStack guide for more information.

Assign a name to the destination and click on Next. You should then see the following screen:

Connection settings

The following connection settings are required to configure AppsFlyer as a destination in RudderStack:

AppsFlyer Dev Key: Enter your AppsFlyer Dev key here.

Refer to the FAQs section below for more information on obtaining the AppsFlyer dev key.

App ID: Enter your Apple or Android app ID.
- Android App ID: This the application ID used in your app/build.gradle file.
- Apple App ID: This is the iTunes Application ID and it is mandatory for the iOS applications.

If you are connecting a source other than Android or the Apple (iOS, watchOS, iPadOS, tvOS), you need to add a user transformation that adds the OS information required in the events.

Refer to the Connecting AppsFlyer to non-Android/iOS sources section below for more information.

Sharing Filter: By default, the value for this setting is set to all. You can use this setting to meet any regulatory requirements like GDPR and CCPA, complying with user opt-out mechanisms, and for any other business use-case.

For more information on this field, refer to the AppsFlyer Help Center page.

Client-side Event Filtering: This setting is applicable only if you are sending events to AppsFlyer via the device mode.

Refer to the Client-side Event Filtering guide for more information on this setting.

Use native SDK to send events: By default, this setting is enabled. To send events via the cloud mode or device mode, you can toggle this setting on or off.

This setting is not applicable for the JavaScript (web) source as RudderStack does not support sending events to AppsFlyer via the web device mode. Refer to the connection modes table in the Getting started section above for more information.

Finally, click on Next to complete the configuration. AppsFlyer will be added and enabled as a destination in RudderStack.

Adding AppsFlyer to your project

Depending on your integration platform , follow the steps to add AppsFlyer to your project:

To add AppsFlyer to your iOS project:

Add the following line to your CocoaPods Podfile:
```
pod 'Rudder-Appsflyer'
```
After adding the dependency, you must register the RudderAppsflyerFactory with your RudderClient initialization as a factory of RudderConfig. To do this, run the following command to import the RudderAppsflyerFactory.h file in your AppDelegate.m file:
```
#import <Rudder-Appsflyer/RudderAppsflyerFactory.h>
```

Then, change the SDK initialization to the following:

RSConfigBuilder *builder = [[RSConfigBuilder alloc] init];
[builder withDataPlaneUrl:DATA_PLANE_URL];
[builder withTrackLifecycleEvens:YES];
[builder withRecordScreenViews:YES];
[builder withFactory:[RudderAppsflyerFactory instance]];
[builder withLoglevel:RSLogLevelDebug];
[RSClient getInstance:WRITE_KEY config:[builder build]];

To add AppsFlyer to your Android project:

Add the repository as shown:
```
repositories {
    mavenCentral()
}
```

Then, add the following line to your app/build.gradle file under dependencies section:

implementation 'com.rudderstack.android.sdk:core:1.+'
implementation 'com.rudderstack.android.integration:appsflyer:1.+'

implementation 'com.appsflyer:af-android-sdk:6.+'
implementation 'com.android.installreferrer:installreferrer:2.+'

Finally, change the initialization of your RudderClient in your Application class, as shown:

val rudderClient: RudderClient = RudderClient.getInstance(
    this,
    WRITE_KEY,
    RudderConfig.Builder()
        .withDataPlaneUrl(DATA_PLANE_URL)
        .withFactory(AppsFlyerIntegrationFactory.FACTORY)
        .build()
)

To add AppsFlyer to your React Native project:

Add the RudderStack-AppsFlyer module to your app using the following command:

npm install @rudderstack/rudder-integration-appsflyer-react-native
// OR //
yarn add @rudderstack/rudder-integration-appsflyer-react-native

Then, import the module you added above and add it to your SDK initialization code as shown:

import rudderClient from "@rudderstack/rudder-sdk-react-native"
import appsflyer from "@rudderstack/rudder-integration-appsflyer-react-native"
const config = {
  dataPlaneUrl: DATA_PLANE_URL,
  trackAppLifecycleEvents: true,
  withFactories: [appsflyer],
}
rudderClient.setup(WRITE_KEY, config)

To add AppsFlyer to your Cordova project, follow these steps:

Navigate to the root folder of your application and run the following command:
```
cordova plugin add rudder-integration-appsflyer-cordova
```

Add the platforms that you want to target for your app:

cordova platform add ios
cordova platform add android

Run the following command to build the project for all the platforms:
```
cordova build
```
Finally, add the following code in the onDeviceReady() function of your home page to initialize the SDK, as shown:
```
RudderClient.initialize(WRITE_KEY , {
  dataPlaneUrl: DATA_PLANE_URL,
  factories: [RudderAppsflyerFactory]
})
```
Make sure to use the await keyword with the initialize call.

Connecting AppsFlyer to non-Android/iOS sources

AppsFlyer supports all the RudderStack sources in addition to Android and iOS. However, you will need to add a transformation to the destination by following these steps:

Go to your RudderStack dashboard.
In the left navigation bar, select Transformations followed by New transformation.
In the Transformation Settings window, assign a Name and Description for the transformation.
Then, add the following function:

export function transformEvent(event, metadata) {
  event.context.os = {
    name: "android",
    version: "8.1.0"
  };
  return event;
}

Click on Save to save the transformation.
Finally, configure your AppsFlyer destination and connect it to the transformation in the Choose an existing transformation window, as shown:

AppsFlyer transformation settings in RudderStack

If you have already configured your AppsFlyer destination, navigate to the Transformation option, as shown:

Transformation settings after adding destination

Click on Add a transformation and select the transformation you created above.

Sending events via the RudderStack cloud mode

We recommend sending events to AppsFlyer via the cloud mode only in the following two scenarios:

To use RudderStack's Transformations feature to transform your events
To send server-side events

To send events to AppsFlyer, you need the AppsFlyer ID generated by the Appsflyer SDK that is integrated with your app.

Refer to the Obtaining the AppsFlyer ID section below for more information.

Once you obtain the AppsFlyer ID, you can send events to AppsFlyer via the cloud mode by including the externalId key within your events' context. The format of externalId is as shown:

"externalId": [
  {
    "id": "AppsFlyer_ID",
    "type": "appsflyerExternalId"
  }
]

The following table lists the externalId fields:

Field	Description
`id`	Your AppsFlyer ID.
`type`	The type of `externalId`. This must always be set to `appsFlyerExternalId`.

Obtaining the AppsFlyer ID

As mentioned above, the AppsFlyer ID is generated by the Appsflyer SDK integrated with your app.

If the AppsFlyer SDK is directly loaded on your app, refer to this AppsFlyer documentation to obtain the AppsFlyer ID.
If your AppsFlyer SDK is loaded through RudderStack (device mode integration), then you can obtain the AppsFlyer ID by including the code snippet in your app, depending on your platform of integration:

#import <AppsFlyerLib/AppsFlyerLib.h>
NSString *appsflyerId = [AppsFlyerLib shared].getAppsFlyerUID;

import com.appsflyer.AppsFlyerLib;
String appsFlyerId = AppsFlyerLib.getInstance().getAppsFlyerUID(this);

import AppsFlyerIntegrationFactory from "@rudderstack/rudder-integration-appsflyer-react-native/src/bridge"
const appsFlyerId = await AppsFlyerIntegrationFactory.getAppsFlyerId()

Identify

The identify call sets userId through the setCustomerUserId method of AppsFlyerLib.

RudderStack supports the identify calls only in the device mode.

RudderStack sets email from the event traits to AppsFlyer using the native SDK's setUserEmails method, as shown:

[[RSClient sharedInstance] identify:@"developer_user_id"
                                 traits:@{@"email": @"bar@foo.com"}];

Track

RudderStack's track call is mapped to the standard AppsFlyer events wherever possible.

The following table lists the event mapping from RudderStack to AppsFlyer:

RudderStack event	AppsFlyer event
`Products Searched`	`af_search`
`Product Viewed`	`af_content_view`
`Product List Viewed`	`af_list_view`
`Product Added to Wishlist`	`af_add_to_wishlist`
`Product Added`	`af_add_to_cart`
`Checkout Started`	`af_initiated_checkout`
`Order Completed`	`af_purchase`
`Product Removed`	`remove_from_cart`

For any event not present in the above table, RudderStack makes the following changes to the event name before sending it to AppsFlyer via the native SDK:

Converting the entire event name to lower case
Replacing any space with an underscore

Along with the above event mapping, RudderStack also maps the event properties to the corresponding AppsFlyer event properties, as shown below:

RudderStack property name	AppsFlyer property name
`query`	`af_search_string`
`price`	`af_price`
`product_id`	`af_content_id`
`category`	`af_content_type`
`currency`	`af_currency`
`products`	RudderStack formulates this list as per the List View specification and passes it to the property `af_content_list`.
`quantity`	`af_quantity`
`order_id`	`af_receipt_id`
`revenue`	`af_revenue`

A sample track call for an iOS app is shown below:

[[RSClient sharedInstance] track:@"Accepted Terms of Service"
                          properties:@{
                                  @"foo": @"bar",
                              @"foo_int": @134
}];

Screen

For all the screen calls sent from the SDK, RudderStack calls AppsFlyer's trackEvent method with screen as the event name. All the event properties are passed to AppsFlyer without any modification.

For the automatically recorded screen calls, RudderStack obtains a Boolean property called automatic.

Advertising ID

RudderStack utilizes the advertising ID for the AppsFlyer destination if it is set as per the following specifications:

For iOS: Advertisement ID documentation
For Android: Advertisement ID documentation

You can find the advertising ID in your event's context.device.advertisementId.

ATTrackingManager

If the ATTrackingManager.trackingAuthorizationStatus is passed according to ATTrackingManager authorization consent, RudderStack will utilize it for the AppsFlyer destination.

You can find trackingAuthorizationStatus in your event's context.device.attTrackingStatus.

Error messages

This section covers some of the possible error messages you may encounter while using this integration.

Invalid platform / required androidAppId / appleAppId missing

This error occurs when either the OS Name or your respective App ID is not set.

You can set the App ID in your settings.

The SDK automatically sets the OS Name and it can be found in context.os.name.

Appsflyer ID is not set. Rejecting the event.

This error occurs when the appsflyerExternalId is not set. Refer to the Sending events via the RudderStack cloud mode section for more information on setting the appsflyerExternalId.

Debugging

RudderStack sets the logLevel in AppsFlyer based on the logLevel set for the RudderClient. If it is set to DEBUG or more, RudderStack sets the logLevel to VERBOSE for AppsFlyer.

For anything below that, RudderStack sets the logLevel to NONE for AppsFlyer.

FAQs

Where do I get the AppsFlyer dev key?

You can find the AppsFlyer Dev Key by logging into your AppsFlyer account and navigating to the Apps Settings page in your dashboard. For more information, refer to this AppsFlyer Help Center page.

I get an error saying "Build input file cannot be found" for iOS device mode. What should I do?

The latest AppsFlyer SDK requires XCode 12. Make sure you meet this requirement. You may have to downgrade your AppsFlyer SDK to build with a lower version of XCode.

You can declare the pod version in your Podfile as shown:

pod 'Rudder-Appsflyer',' 1.0.0'

How do I get the AppsFlyer ID to send events from my mobile sources via the RudderStack cloud mode?

To send events to AppsFlyer via the cloud mode, you first need to obtain the AppsFlyer ID generated by the Appsflyer SDK.

You can get this ID by either directly loading the native AppsFlyer SDK on your app, or loading it via RudderStack (device mode integration).

In case of a device mode integration, include the following code snippet (depending on your platform of integration) in your app to get the AppsFlyer ID:

#import <AppsFlyerLib/AppsFlyerLib.h>
NSString *appsflyerId = [AppsFlyerLib shared].getAppsFlyerUID;

import com.appsflyer.AppsFlyerLib;
String appsFlyerId = AppsFlyerLib.getInstance().getAppsFlyerUID(this);

import AppsFlyerIntegrationFactory from "@rudderstack/rudder-integration-appsflyer-react-native/src/bridge"
const appsFlyerId = await AppsFlyerIntegrationFactory.getAppsFlyerId()

Once you obtain the AppsFlyer ID, you can send events via the cloud mode by by including the externalId key within your events' context. For more information, refer to the Sending events via the RudderStack cloud mode section above.
