AppsFlyer Destination

AppsFlyer is the world’s leading mobile attribution & marketing analytics platform, helping app marketers around the world make better decisions. Our AppsFlyer destination code is open-source. You can browse the code on GitHub for iOS and Android.

This document was last updated on April 27, 2018. If you notice any gaps, outdated information or simply want to leave some feedback to help us improve our documentation, let us know!

Getting Started

Before you start, make sure AppsFlyer supports the source type and connection mode you’ve chosen to implement. You can learn more about connection modes here.

1. From the Segment web app, click Catalog.
2. Search for “AppsFlyer” in the Catalog, select it, and choose which of your sources to connect the destination to.
3. In the destination settings, enter your AppsFlyer Dev Key, which can be retrieved from the App Settings section of your AppsFlyer account.
4. Follow the instructions in the GitHub repos: iOS SDK and Android SDK.
5. After you build and release to the app store, we start translating and sending your data to AppsFlyer automatically.

Important: If you plan on using the server-side destination for an Android project, make sure to enter your Android App ID. If you are using only the mobile SDK, Android projects only require the AppsFlyer Dev Key. iOS projects always require both the AppsFlyer Dev Key and the Apple App ID. Also, note that if you do use the server-side destination, you will not be able to selectively disable calls sent to AppsFlyer using your Segment dashboard.

Additional device-mode set up for iOS 14 support

Segment updated the AppsFlyer iOS SDK to use version 6.0 beta to prepare for tracking changes in iOS 14. The SDK beta version is compatible with the beta version of iOS 14 released by Apple, and supports both AppsFlyer’s aggregate attribution, and Apple’s AppTrackingTransperancy framework, and more. See the AppsFlyer blog post about AppsFlyer’s new privacy-centric attribution model.

To use the latest AppsFlyer SDK to collect IDFAs, do the following:

1. Upgrade to use Xcode12.
2. Update your Segment AppsFlyer SDK to version 6.0.2 or later.
3. Import and implement the AppTrackingTransparency (ATT) Framework.
   • Navigate to your project Info.plist and add a “Privacy - Tracking Usage Description”. This description appears in a popup when the application initializes in iOS 14. Users are prompted to indicate whether or not they want to allow tracking.

4. Add and customize the following code in your AppDelegate.m file on didFinishLaunchingWithOptions to allow AppsFlyer collect IDFAs.

   // The following block is for applications wishing to collect IDFA.
   // for iOS 14 and later - The user will be prompted for permission to collect IDFA.
   // If permission granted, the IDFA will be collected by the SDK.
   // for iOS 13 and earlier - The IDFA will be collected by the SDK. The user will NOT be prompted for permission.
   if #available(iOS 14, *) {
       // Set a timeout for the SDK to wait for the IDFA collection before handling app launch
       AppsFlyerLib.shared().waitForAdvertisingIdentifier(withTimeoutInterval: 60)
       // Show the user the Apple IDFA consent dialog (AppTrackingTransparency)
       // Can be called in any place
       ATTrackingManager.requestTrackingAuthorization { (status) in
       }
   }
   

5. Follow Segment’s guide for collecting IDFA

Additional iOS Cloud Mode Set up for iOS 14

With the release of Segment’s latest Analytics-iOS SDK, which includes support for upcoming iOS 14 tracking changes, you must decide if you need to collect the user’s IDFA or not. If you do not need to collect IDFA, you can update your Analytics-iOS SDK to the next version, and Segment sets device.adTrackingEnabled to false, and starts deleting the device.advertisingId from the context object in your payloads. If you do need to collect the IDFA, you must import the IDFA closure as a config to the library, or import the Ad Tracking Transparency framework from Apple.

If you have the Can Omit AppsFlyerID setting enabled, but aren’t sending an IDFA (either because you aren’t passing one, or the user denied permission to collect it), AppsFlyer rejects the event.

To prevent this, you can enable the new Fallback to send IDFV when advertisingId key not present setting in your AppsFlyer destination settings. With this enabled, when you send data using cloud-mode (through the Segment servers), Segment sends the user’s IDFV (the device.id) when device.advertisingId is missing or blank AND “Can Omit AppsFlyerID” is enabled.

Server

AppsFlyer offers an augmentative server-side HTTP API intended for use along side the AppsFlyer mobile SDK. Use the cloud-mode destination with the mobile SDK to link out-of-app events (such as website or offline purchases) with attributed users and devices.

Important: The cloud-mode destination is not meant to replace the device-mode destination, and you should not use the cloud-mode destination by itself. AppsFlyer requires that you bundle the mobile SDK to correctly attribute user actions. Remember that if you pass in an appsFlyerId on cloud-mode calls, you cannot prevent events from sending to AppsFlyer from the Segment app.

If you want to use AppsFlyer server-side only, contact your AppsFlyer representative, as this is an Enterprise Customer Feature.

Identify

If you’re not familiar with the Segment Specs, take a look to understand what the Identify method does. An example iOS call would look like:

[[SEGAnalytics sharedAnalytics] identify:@"12091906-01011992"
                                traits:@{ @"email": @"john.doe@example.com" }];

When you call .identify(), we will use AppsFlyer’s setCustomerUserID to send the userId that was passed in.

Note: identify calls are not supported using AppsFlyer’s HTTP API at the moment. You can only send .identify calls if you have the AppsFlyer SDK bundled.

Track

If you’re not familiar with the Segment Specs, take a look to understand what the Track method does. An example iOS call would look like:

[[SEGAnalytics sharedAnalytics] track:@"Article Completed"
                           properties:@{ @"title": @"How to Create a Tracking Plan", @"course": @"Intro to Analytics" }];

When you call track, Segment translates it automatically and sends the event to AppsFlyer.

We include all the event properties as callback parameters on the AppsFlyer event, and automatically translate properties.revenue to the appropriate AppsFlyer purchase event properties based on our spec’d properties.

Finally, we automatically use AppsFlyer’s transactionId deduplication when you send an an orderId (see the e-commerce spec).

Server

If you’d like to attribute offline events with a certain user or device, the server-side destination may be employed.

AppsFlyer requires the following properties for this attribution:

AppsFlyer Device ID

Send the AppsFlyer Device ID with each event at integrations.AppsFlyer.appsFlyerId, see example below. This identifier is unique to each device and can be retrieved using the AppsFlyer SDK. It is a good idea to store this value in an external database where it may be easily accessible by a server or website environments.

Device Type

AppsFlyer requires the user’s device type as either 'ios' or 'android', passed at context.device.type object, see example below.

Advertising ID

AppsFlyer requires the passing of an Advertising ID (referred to as IDFA on iOS and Advertising ID on Android) at context.device.advertisingId, see example below:

// node.js library example
analytics.track({
  event: 'Membership Upgraded',
  userId: '97234974',
  context: {
    device: {
      type: 'ios',
      advertisingId: '159358'
    }
  },
  integrations: {
    AppsFlyer: {
      appsFlyerId: '1415211453000-6513894'
    }
  }
});

Check your specific serverside library docs for specifics on how to format the method properly.

Finally, the serverside component will look for the following properties and handle them specially:

• ip (this should be the ip of your customer–this is not collected by Segment’s libraries out-of-the-box)
• timestamp (refer to AppsFlyer’s docs on how they process timestamps. Since our libraries generate a timestamp, we will always set this value)
• currency (defaults to "USD")
• revenue (For Order Completed events, precedence is given to total, falling back to properties.revenue)

All other properties will be sent to AppsFlyer as custom properties inside eventValue.

Note: Be sure to calibrate/update the time window in AppsFlyer’s dashboard to see your events!

Install Attributed

Client

Segment will automatically trigger an Install Attributed event if you have trackAttributionData enabled in your settings, and the Segment-AppsFlyer integration installed in your app. The event payload will adhere to our Install Attributed event specification documented here and will propagate to your other downstream destinations.

Server

If you are tracking events server-side, AppsFlyer can still send attribution postbacks but you will need to configure this functionality in your AppsFlyer account. To enable this, navigate to your AppsFlyer app and on the sidebar of the main screen click on Integrated Partners and search for Segment. You will be prompted with a couple of configuration options and asked to input your Segment Write Key. Once enabled, successfully attributed app installs will begin showing up as Install Attributed events similar to the client side behavior documented above.

If you are sending in the attribution data yourself, for iOS be sure the following properties are sent in within the campaign object on the Install Attributed or Application Opened event so Appsflyer can correctly attribute it as an Apple Search Ad event. These values should be returned by the Apple Search Ads API:

"campaign": {
        "content": "keyword1keyword2",
        "ad_creative": "OrgName",
        "conversion_date": "2018-03-07T04:05:50Z",
        "ad_group": "US-iOS-campaign-Exact",
        "id": "123",
        "ad_group_id": "456",
        "name": "US-iOS-campaign",
        "click_date": "2018-03-06T04:05:50Z",
        "lineitem_id":"789",
        "attribution":"true",
        "lineitem_name":"US-iOS-campaign-Name"
      }

For example, an attribution event coming from an attribution partner would look like:

[[SEGAnalytics sharedAnalytics] track:@"Install Attributed", properties: @{
    @"provider" : @"Appsflyer/Tune/Kochava/Branch",
    @"campaign" : @{
        @"source" : @"Network/FB/AdWords/MoPub/Source",
        @"name" : @"Campaign Name",
        @"content" : @"Organic Content Title",
        @"ad_creative" : @"Red Hello World Ad",
        @"ad_group" : @"Red Ones",
        @"conversion_date": @"2018-03-07T04:05:50Z",
        @"id": @"123",
        @"ad_group_id": @"456",
        @"click_date": @"2018-03-06T04:05:50Z",
        @"lineitem_id":@"789",
        @"attribution":@"true",
        @"lineitem_name":@"US-iOS-campaign-Name"
    }
}];

Other Features

Revenue Tracking

The destination automatically recognizes spec’d revenue property and translates them to AppsFlyer’s revenue tracking method.

Transaction De-duplication

The destination automatically recognizes the spec’d orderId property, and sends it as the Transaction ID to AppsFlyer for revenue de-duplication.

In-App Purchase Receipts

The destination does not currently support in-app purchase receipts. If this is important to you, email support@appsflyer.com.

Deeplinking

The destination does not automatically support out-of-the-box deeplinking (you need to write code here regardless!).

Therefore, you can use AppsFlyer’s OneLink integration which is a single, smart, tracking link that can be used to track on both Android and iOS. OneLink tracking links can launch your app when it is already installed instead of redirecting the user to the app store.

For more details, review the AppsFlyer OneLink set up Guide. More information is available in the AppsFlyer SDK Integration Guides (iOS, Android) and Segment’s mobile FAQs (iOS, Android).

Personas

You can send computed traits and audiences generated using Segment Personas to this destination as a user property. To learn more about Personas, contact us for a demo.

For user-property destinations, an identify call is sent to the destination for each user being added and removed. The property name is the snake_cased version of the audience name, with a true/false value to indicate membership. For example, when a user first completes an order in the last 30 days, Personas sends an Identify call with the property order_completed_last_30days: true. When the user no longer satisfies this condition (for example, it’s been more than 30 days since their last order), Personas sets that value to false.

When you first create an audience, Personas sends an Identify call for every user in that audience. Later audience syncs only send updates for users whose membership has changed since the last sync.

Settings

Segment lets you change these destination settings from the Segment app without having to touch any code.

Android App ID

Your Android App’s ID. Find this in your AppsFlyer’s ‘My App’ dashboard. It should look something like ‘com.appsflyer.myapp’. This is required for Android projects if you want to send events using the server side integration.

Apple App ID (iOS)

Your App’s ID, which is accessible from iTunes or in AppsFlyer’s ‘My App’ dashboard. This is optional for Android projects, and only required for iOS projects.

AppsFlyer Dev Key

Your unique developer ID from AppsFlyer, which is accessible from your AppsFlyer account.

Can Omit AppsFlyerId

Only applicable for Appsflyer’s Business Tiers customers using server-side or cloud mode destination. Please contact your AppsFlyer representative for more information. This setting allows to use the advertising ID as appsflyer ID.

Enable HTTP fallback (Android)

If selected, HTTPS calls will fallback on HTTP

Fallback to send IDFV when advertisingId key not present (Server-Side Only)

With the update to use analytics-ios v4.x SDK if adTrackingEnabled is set to false, the advertisingId key will be deleted from the event. If you have the setting enabled “Can Omit AppsFlyerId”, these events will fail when sent to AppsFlyer API. To prevent these event failures in this scenario enable this send the IDFV instead. When the “Can Omit AppsFlyerId” setting is enabled if the IDFA is zeroed out, we will also send an IDFV when this setting is enabled.

Roku App ID

IMPORTANT: In order to send Roku data, you must contact your AppsFlyer representative as this type of data stream requires a full server to server integration which is available but is gated as a AppsFlyer Enterprise Customer feature. Without AppsFlyer’s consent we are unable to forward your Roku data. Your Roku App’s ID. Find this in your AppsFlyer’s ‘My App’ dashboard. This is required for Roku projects if you want to send events using the server side integration.

Track Attribution Data

Send attribution data to Segment and other tools as a track call (mobile libraries only).
