Log OneSignal Push Notification with Firebase Analytics Event

Question

So my goal is to log event any push notification that comes up on my app. I'm using Firebase Analytics to log any event and I already know how to use it using :

Analytics.logEvent(FirebaseEventName, parameters: [:])

But is it possible to log event a push notification? I'm using OneSignal as my Push Notification service.

Answer 1

I've found my answer. But my method required Backend to be involved. Which I don't have the answer because I don't handle the Backend part. The following answer is only just for iOS part only.

So, the method is using OneSignal method, and it's implemented in

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {

If you're already using OneSignal for iOS you should already write below code in didFinishLaunchingWithOptions

OneSignal.initWithLaunchOptions(launchOptions, appId: ONE_SIGNAL_APPID, handleNotificationReceived: { (notification) in
        let additionalData = notification?.payload.additionalData // Get additional data such as custom flaging from backend
        if additionalData != nil { // A condition to avoid crash if additionalData is empty
            let customFlag:String = additionalData!["tipe"] as! String // Get value of the custom flag, in this case mine is "tipe", and store the value to customFlag
            Analytics.logEvent(customFlag, parameters: [:]) // Send Log Event to Firebase
        }
    }, handleNotificationAction: { (result) in

    }, settings: [kOSSettingsKeyInFocusDisplayOption: OSNotificationDisplayType.none.rawValue,kOSSettingsKeyAutoPrompt : true])

For example, if you print additionalData the value should be looking like

[AnyHashable("tipe"): inbox]

And this value is set/declared in Backend part.
