Messaging: How do you read custom data?

[nijakobius]

When scheduling a Firebase Messaging campaign, you can optionally pass custom data to be read in the app (see attached screen shot).

Any idea how to read that data from within the app?

I've tried all of this plugin's functions and event listeners (like notificationReceived) and none of them worked. I've also tried Capcitor's App plugin's functions and event listeners (like the appUrlOpen).

Or is there an alternative way for the app to know which it is opened from?

This is the UI for in-app messaging and not messaging. An in-app messaging plugin does not exist yet, see #129.

I am wondering is capacitor's push notifications plugin won't work? or are they not compatible?

What do you mean exactly?

No, this is the notifications UI. The one you get from Firebase > Messaging > New Campaign > Notifications (not In-app messaging) > Additional options (optional) > Custom data.

(Or am I misunderstanding what you meant?)

Okay, this should work. Have you tried the following?

import { FirebaseMessaging } from '@capacitor-firebase/messaging';

const addNotificationReceivedListener = async () => {
  await FirebaseMessaging.addListener('notificationReceived', event => {
    console.log(event.notification.data);
  });
};

That's it! I'm pretty sure I had tried that but maybe I did a mistake. This time round it worked - thanks! :)

this listener isn't working for me on iOS (haven't tested it on Android), is there a bug on 5.1.0?

"@capacitor-firebase/messaging": "^5.1.0"

Ok my issue was this one #267 (comment)
Should have read the docs with more attention
