Intro

Capacitor provides a native mobile runtime and API layer for web apps. It allows mobile frontend frameworks (such as Ionic Framework) to access native device features.

The Advertising Identifier (IDFA on iOS, AAID on Android) is a device-specific, unique, resettable ID for advertising that allows ddevelopers and marketers to track activity for advertising purposes.

This npm module allows any mobile application that uses Capacitor to access the Advertising ID, following the OS specific definition and user permissions.

The module output in the javascript framework is the following:

interface AdvertisingInfoResponse {
  id: string; // the Advertising ID (or null if not defined/permitted)
  isAdTrackingLimited: boolean; // the user defined permission to track
}

Note

In version 2.0 we switched to Capacitor 3.0 and there are breaking changes, so if you are on Capacitor 2.x don't upgrade or just use version 1.x

Supported platform

• Android
• iOS

Note: the web version always returns null

  AdvertisingInfoResponse,
} from '@sparkfabrik/capacitor-plugin-idfa';

// Get advertising id.
Idfa.getAdvertisingInfo()
  .then((response: AdvertisingInfoResponse) => {
    if (response.isAdTrackingLimited === true) {
      console.error('Ads tracking not allowed by user.');
    }
    console.log(response.id);
  })
