AppsFlyer Analytics & OneLink

AppsFlyer provides comprehensive mobile analytics and attribution tracking. This guide covers both the OneLink deep linking integration and privacy configuration options available in Zapp.

Overview​

OneLink is AppsFlyer's smart deep linking solution that allows you to create a single, universal link that automatically redirects users to the correct app store, landing page, or in-app content.

For more details on OneLink integration, refer to the AppsFlyer support forum.

Privacy & Data Protection​

AppsFlyer offers configurable privacy controls to help you comply with data protection regulations and user consent requirements. These include:

  • Anonymize User & Disable Advertising IDs: Strict privacy mode that anonymizes user data and disables ad tracking identifiers
  • Block 3rd Party Data Sharing: Prevent data sharing with third-party partners while maintaining attribution tracking
  • IDFA/Advertising ID Management: Fine-grained control over advertising identifier collection (requires separate IDFA plugin)

Prerequisites​

  • An AppsFlyer account. Follow the Getting Started Guide.

  • AppsFlyer dev key, available in your dashboard, which is used for SDK integration.

  • Branded OneLink domain setup (for deep linking). This involves:

    • Setting up your custom domain in AppsFlyer.

    • Creating new OneLink URLs using this domain. For detailed instructions, refer to Brand OneLink with your domain.

  • AppsFlyer plugin added to the relevant version.

iOS Configuration​

Basic Setup​

  1. Go to the Plugin Configuration section of your iOS app and fill in the following fields:

    • AppsFlyer Key: Your app's unique identifier from the AppsFlyer dashboard
    • Apple App ID: Found in the App Store (also called Bundle ID)
    • SKAdNetworks: Leave this field blank
    • SKAdNetwork Endpoint: Pre-filled; no changes needed
    • Plugin Enabled: Ensure this is enabled

Deep Linking Setup​

  1. Under the General Settings of your iOS version, add your Universal Links to the Universal Links field:

Android Configuration​

Basic Setup​

  1. Go to the Plugin Configuration section of your Android app and complete the following:

    • AppsFlyer Key: Your app's unique identifier from the AppsFlyer dashboard

Privacy Configuration Options​

Zapp provides two privacy-focused toggles for Android:

Anonymize User & Disable Advertising IDs​

Enables strict privacy mode with the following effects:

  • Anonymizes user data: All user identifiers are anonymized
  • Disables advertising identifiers: Prevents collection of GAID (Google Advertising ID)
  • Disables install attribution: Attribution tracking is disabled
  • When to use: For apps targeting children (COPPA compliance), sensitive content, or regions with strict privacy requirements
note

The effectiveness of advertising ID disabling depends on whether the IDFA and Advertising ID Management plugin is also installed and enabled. With the IDFA plugin installed, you can further control advertising ID collection independently.

For more details, see AppsFlyer Anonymization.

Block 3rd Party Data Sharing​

Prevents AppsFlyer from sharing user data with third-party partners via:

  • Postbacks
  • APIs
  • Raw data reports
info

This setting only affects third-party sharing and does not prevent attribution data collection. AppsFlyer will continue to track installs and user events for your analytics.

Additional Privacy Control: IDFA Plugin​

For granular control over advertising ID collection, add the IDFA and Advertising ID Management plugin. This allows you to:

  • Toggle advertising ID collection on/off independently
  • Customize the ATT (App Tracking Transparency) prompt on iOS
  • Prevent unintended advertising ID collection by third-party SDKs

See the IDFA Control documentation for detailed setup instructions.

Deep Linking Setup​

  1. In the General Settings of your Android version:

    • Add your branded domain to the App Links Hosts field.
    • Add /fake under the App Links Patterns field (required for proper intent filter matching):

Domain Association for Deep Linking​

To enable deep linking with OneLink on Android, your app must be associated with your branded domain using Digital Asset Links.

You can either:

  1. Self-host the file at:

    https://your-domain.com/.well-known/assetlinks.json

  2. Let AppsFlyer host it for you.

    In this case, provide AppsFlyer with:

    • The app's package name
    • The SHA256 fingerprint of your app's signing key
    Tip

    To test on Zapp debug builds, use this key fingerprint: 65:F4:11:CB:1F:EB:5B:45:73:D6:D8:85:55:01:61:88:17:D5:09:65:E9:D9:72:9A:75:9D:68:47:18:F7:87:78

    • For production, find the key in Google Play Console under Release > App Integrity
