The app is on both iOS and Android, for this notification to work on both platforms, I removed notification field from notification json payload. But now iOS does not handle this notification when in background.

This one works on iOS but it has notification field which I do not want.

{
  "registration_ids": [
        "...",
        "..."
    ],
  "priority": "high",
  "notification": {
    "body": "Notification Body.",
    "title": "Notification Title"
  },
  "data": {
    "userId": "11111",
    "badge": 10
  }
}

This one works in android but not working on iOS when in background:

{
  "registration_ids": [
        "...",
        "..."
    ],
  "mutable_content": true,
  "content_available": true,
  "data": {
    "click_action": "AndroidIntent"
    "message": "Notification Body",
    "myDataField": "11",
    "location": "3",
    "imageurl": "http://image.com/13fd.png"
  }
}

The bottom one does not even enter my Notification Service Extension. How do I make sure my Notification Service Extension is called without adding a notification field on my json?

    Did the above one with "notification" key in the payload enters Notification Service Extension? I'm having same problem as well. My Notification Service doesn't get called that's why I cannot create a thumbnail on my notification via FCM. – Jongers Jan 25 '19 at 07:34

I have the same thoughts. I was thinking of receiving data from firebase and push local notification with customized title and body with notification service extention. This idea worked fine in foreground by implementing didReceiveRemoteNotification userInfo: in appDelegate to receive userInfo.

But it didn't work in background mode by enabling content_available. you send notification using APN Servers not Fcm Servers relating to firebase docs. I suggest to have a look in content_available and mutable_content

Remove content_available since this is the property to handle silent notifications.
