AppsFlyer iOS

Send iOS app events and conversions to AppsFlyer server-to-server for mobile attribution, SKAdNetwork support, and campaign analytics.

⚠️

This blueprint is currently alpha — schema and behaviour may change before GA.

Prerequisites

Complete these steps in the AppsFlyer dashboard and App Store Connect before configuring Signal.

Create an AppsFlyer account

Sign up at appsflyer.com and log in to the AppsFlyer dashboard.

Register your iOS app

Click Add App in the dashboard, select iOS, and enter your app’s Apple App ID or search by name. The app must be live on the App Store or registered in App Store Connect.

Find your Dev Key

Navigate to Configuration > App Settings in the left sidebar. Your Dev Key is displayed at the top of the page. Copy this value.

Generate an API token

Go to Security Center (accessible from the top-right user menu or under Configuration). Generate a V2 API Token. This token authenticates all server-to-server event calls.

Find your Apple App ID

Log in to App Store Connect, open your app, and locate the numeric Apple ID on the App Information page (e.g. 123456789). This is required for SKAdNetwork attribution.

Note your AppsFlyer App ID

Your AppsFlyer App ID for iOS is typically in the format id123456789 (the id prefix followed by your Apple App ID).

Configuration

FieldTypeRequiredDescription
app_idstringYesThe AppsFlyer app ID for your iOS app (e.g. id123456789).

Signal Setup

Quick Setup

  1. Navigate to Integrations in the sidebar.
  2. Open the Integration Library tab.
  3. Find AppsFlyer iOS or filter by Attribution.
  4. Click Install, select a variant if available, and fill in the required fields.
  5. Click Install Integration to create the integration with a ready-to-use default blueprint.

API Setup

curl -X POST http://localhost:8084/v1/admin/integration-catalog/appsflyer_ios/install \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "AppsFlyer iOS",
    "variant": "default",
    "config": {
      "app_id": "id123456789",
      "dev_key": "AbCdEfGhIjKlMnOpQrSt",
      "api_token": "your_api_token",
      "apple_app_id": "123456789"
    },
    "delivery_mode": "server_side"
  }'

Event Mapping

The Retail variant maps the following Datafly events to AppsFlyer in-app event names:

Datafly EventAppsFlyer EventNotes
Product Viewedaf_content_viewProduct details map to af_content_id, af_price, af_currency
Product Addedaf_add_to_cartProduct details map to af_content_id, af_price, af_currency
Order Completedaf_purchaseRequires af_revenue, af_currency, af_order_id
Custom eventsPassed throughAdd the AppsFlyer event name in the blueprint event map

Identity

The default blueprint forwards the following identifiers to AppsFlyer:

SourceAppsFlyer field
vendor_ids.appsflyer_idappsflyer_id
vendor_ids.idfaidfa (when available)
vendor_ids.idfvidfv
context.ipip
context.user_agentuser_agent

Capture appsflyer_id from the AppsFlyer iOS SDK at app start and pass it via the Datafly mobile SDK — every S2S event requires it. idfa (iOS only, post-ATT consent) improves attribution accuracy when present.

Default consent category: advertising. Gate behind advertising consent in your CMP, and only forward idfa when the user has granted App Tracking Transparency.

AppsFlyer requires the appsflyer_id device identifier on every S2S event. For iOS, the idfa (Identifier for Advertisers) is also recommended when available for improved attribution accuracy.

Verify it’s working

  1. Install your iOS app on a test device and trigger the events you want to track.
  2. In the Signal Management UI, open your AppsFlyer iOS integration and watch the Live Events stream.
  3. In the AppsFlyer dashboard, navigate to Activity > Event Timeline and filter by your test device.
  4. Verify the event name, revenue, and custom parameters match expectations.
  5. Confirm 200 responses in Signal’s Live Events log.
