Deep Linking Types

Since users may or may not have the mobile app installed, there are 2 types of deep linking:

Deferred Deep Linking - Serving personalized content to new or former users, directly after the installation.
Direct Deep Linking - Directly serving personalized content to existing users, which already have the mobile app installed.

For more info please check out the OneLink™ Deep Linking Guide.

The set up for deferred deep linking and direct deeplinking is the same for UE4:

Create a new Actor object.
Click Add Component and and the AppsFlyer SDKCallback Component.
You can now add the required callbacks.

Now you are ready to implement Deeplinking!

Deferred Deep Linking

Check out the deferred deeplinkg guide from the AppFlyer knowledge base here

Code Sample to handle the conversion data:

Direct Deeplinking

When a deeplink is clicked on the device the AppsFlyer SDK will return the link in the onAppOpenAttribution method.

Android Deeplink Setup

URI Scheme

In your app’s manifest add the following intent-filter to your relevant activity:

<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="your unique scheme" />
</intent-filter>

iOS Deeplink Setup

For more on Universal Links check out the guide here.

Essentially, the Universal Links method links between an iOS mobile app and an associate website/domain, such as AppsFlyer’s OneLink domain (xxx.onelink.me). To do so, it is required to:

Configure OneLink sub-domain and link to mobile app (by hosting the ‘apple-app-site-association’ file - AppsFlyer takes care of this part in the onelink setup on your dashboard)
Configure the mobile app to register approved domains:
