Apple Ad Attribution

AdNetworksID

To ensure proper ad attribution and maximize revenue performance, you must configure both SKAdNetworkItems and AdAttributionKit identifiers in your app’s Info.plist.

Proper configuration ensures that your app can attribute installs and in-app conversions correctly under Apple’s privacy framework:

  • Ensures full attribution coverage
  • Unlocks optimized campaign bidding
  • Improves fill rate and competition
  • Increases eCPM
  • Prevents revenue loss

From a monetization standpoint, missing SKAdNetwork or AdAttributionKit identifiers directly impacts your ability to compete in privacy-safe performance campaigns.

We strongly recommend validating this configuration before every production release.

Failure to properly configure these values may result in:

  • Lost attribution data
  • Lower campaign performance visibility
  • Reduced eCPM and monetization efficiency
  • Inability to measure post-install performance

SKAdNetwork

SKAdNetwork is Apple’s privacy-preserving attribution framework introduced in iOS 14 to replace traditional device-level attribution.

It allows ad networks to measure app installs and post-install events without accessing user-level identifiers (IDFA).

Official Apple documentation about SKAdNetwork

Each ad network participating in SKAdNetwork must register its unique SKAdNetwork ID. To receive attribution postbacks, your app must include these IDs in Info.plist SKAdNetworkItems

AdAttributionKit

AdAttributionKit is Apple’s next-generation attribution framework introduced in iOS 17.4 that extends and evolves SKAdNetwork. It provides more advanced attribution capabilities and improved privacy-preserving reporting.

Official Apple documentation about AdAttributionKit

AdAttributionKit identifiers must also be declared in your Info.plist to enable proper attribution for supported campaigns.

Automated Integration

To simplify the integration process and eliminate manual errors, we provide a Ruby script to CAS.AI Automatically configure project.

This script will automatically inject required SKAdNetworkItems and AdNetworkIdentifiers identifiers into your Info.plist.

Manual Integration

An up-to-date list of SKAdNetworkItems and AdAttributionKit partners can be found in the repository.

  1. Open your project in Info.plist as Source Code.
  2. Copy the <key>SKAdNetworkItems</key><array>...</array> tags from the SKAdNetworkItems.xml.
  3. Paste the content inside SKAdNetworkItems <array> tag or at the end of the file before </dict></plist>
  4. Copy the <key>AdNetworkIdentifiers</key><array>...</array> tags from the AdNetworkIdentifiers.xml.
  5. Paste the content inside AdNetworkIdentifiers <array> tag or at the end of the file before </dict></plist>

Additional SKAdNetworkItems and AdNetworkIdentifiers values may be added in the future. We recommend checking back on this page for updates.

Best Practices

  • Keep identifiers updated — Apple and ad networks may introduce new ones.
  • Re-run the Ruby script when updating the SDK.
  • Validate configuration before App Store submission.
  • Monitor attribution performance after release.
