AppsFlyer

Last updated: May 22, 2026

AppsFlyer is a mobile attribution and analytics platform that tracks how users discover and engage with your app. Once connected, it automatically records installs and app opens, and you can log additional custom events from your website using the JavaScript Bridge.

Required Credentials

Dev Key

Your AppsFlyer Dev Key uniquely identifies your account and links the app to your AppsFlyer dashboard.

Where to find it:

  1. Log in to your AppsFlyer Dashboard.

  2. Go to your app's Settings page.
  3. Copy the Dev Key.

App ID

Your app's identifier in AppsFlyer.

  • iOS: Use only the numeric part of your App Store ID. If your App Store URL contains id123456789, enter 123456789.

  • Android: Use your package name, for example com.example.myapp.

What Gets Tracked Automatically

Once the Dev Key and App ID are entered, AppsFlyer automatically tracks:

  • App installs (first open after installation)

  • App sessions (each time the app is opened)
  • Re-engagement (returning users from campaigns)

These appear in your AppsFlyer dashboard immediately after the first launch.

Logging Custom Events

To track specific actions in your app — purchases, registrations, content views — use the JavaScript Bridge from your website. See the Logging AppsFlyer Events article for full implementation details and examples.
