AppsFlyer is the market leader in mobile advertising attribution and analytics, helping marketers to pinpoint their targeting, optimize their ad spend and boost their ROI (Return on Investment).

AppsFlyer allows users to monitor and track application installations, downloads, and conversions. The AppsFlyer API allows developers to access and integrate the functionality of AppsFlyer with other applications.


In order to enable AppsFlyer to start tracking your app, you are required to have the following two information such as:

  1. devKey: Your application devKey provided by AppsFlyer.
  2. appId: (For iOS only) Your iOS app ID in the App Store.

Adding AppsFlyer to Monaca Project

  1. For Monaca Cloud IDE, go to Configure → Service Integration Settings .

  2. Click on Details button of AppsFlyer service.

  3. Then, click Install button to add it into your project.

  4. You will be asked to confirm the setup. Click OK to start the installation.


Add the following lines to your code to initialize the tracking with your own AppsFlyer devKey and appId:

document.addEventListener("deviceready", function(){

    var options = {
        devKey:  'xxXXXXXxXxXXXXxXXxxxx8'  // your AppsFlyer devKey

    var userAgent = window.navigator.userAgent.toLowerCase();

    if (/iphone|ipad|ipod/.test(userAgent)) {
        options.appId = "123456789";       // your ios app id in app store


}, false);


SDK Initialization

Initialize the SDK.

initSdk(options, onSuccess, onError): void


Name Type Description
options Object SDK configuration (please refer to the options object table below)
onSuccess (message: string) => void (optional) Success callback: called after a successfull SDK initialization.
onError (message: string) => void (optional) Error callback: called when error occurs during initialization.

options object

function onError(err) {
    // handle error

var options = {
    devKey:  'd3Ac9qPardVYZxfWmCspwL',
    appId: '123456789',
    isDebug: false,
    onInstallConversionDataListener: true

window.plugins.appsFlyer.initSdk(options, onSuccess, onError);

In-App Events Tracking API

Allow you to send in-app events to AppsFlyer analytics. This method allows you to add events dynamically by adding them directly to the application code. These in-app events help you track how loyal users discover your app, and attribute them to specific campaigns/media-sources. Please take the time to define the event(s) you want to measure to allow you to track ROI (Return on Investment) and LTV (Lifetime Value).

trackEvent(eventName, eventValues): void (optional)


Name Type Description
eventName String Custom event name, is presented in your dashboard.
eventValue Object Event details


The following snippet shows how to use trackEvent() function:

var eventName = "af_add_to_cart";
