Does firebase set apns-push-type header automatically?

Question

According to changes in iOS 13 for APNS, silent push notifications require additional header (apns-push-type).

I use Firebase as a mediator between backend and mobile, and I'm wondering if Firebase sets mentioned header automatically when content-available property is set to true.

It is already happening in AWS, as mentioned here.

Can I check somehow in iOS if this header was passed to silent push notification?

I've tested on my devices and everything is working after I updated Firebase dependency to the newest version, even in background. But still I don't have any proof how the header looks like.

Hi @Nominalista, currently fireabase does not provide any documentation regarding iOS 13 update. You can connect their support, I guess they add this header you can check in iOS 13. I will check on my end and update you. – Adim

Thanks, please let me know, when you will find out something. – Marry

After digging around a little bit and checking how some open source projects updated their code, here's an example on how to add apns-push-type to Firebase Admin Node:

(I'm using multicast, so your solution might differ.)

const message = {
  priority: 'high',
  sound: 'default',
  notification: {
    title: 'Message Title',
    body: 'Message Body',
  },
  android: { ... },
  apns: {
    headers: {  // Add these 3 lines
      'apns-push-type': 'alert',
    },
    payload: {
      aps: {
        badge: 1,
        sound: 'default',
      },
    },
  },
  tokens: [ ... ],
};

admin.messaging().sendMulticast(message);

I only had a few notifications failing so I haven't been able to fully confirm that the problem is solved yet.

This is what i'm using to send background notificaions to the ios devices. Notice that im setting "contentAvailable" instead of "content-available", everything needs to be a string.

"apns": {
    "headers": {
      "apns-push-type": "background",
      "apns-priority": "5"
    },
    "payload": {
      "aps":{
        "contentAvailable": true
      }
    }
  }

i'm using sendMulticast() method, full example looks something like this:

var message = {
  "tokens": tokensArray,
  "data": {
    "info":"someInfo"
  },
  "apns": {
    "headers": {
      "apns-push-type": "background",
      "apns-priority": "5"
    },
    "payload": {
      "aps":{
        "contentAvailable": true
      }
    }
  }
};

await messaging.sendMulticast(message)

Firebase support responded on my request.

As of today, Firebase does not automatically set the apns-push-type header if content_available is set. One should set it via the header in ApnsConfig. They also recommend to update to the lastest admin SDK version.

I additionally set the apns-priorityheader. Unfortunately all steps didn't solve my problem.

Have you tried using underscore? Like apns_push_type? Notice that for Apple accepts content-available property and Firebase accepts content_available in contrast. – Marry
