Notification Channel for Android O

[mdgagne]

• Operating System version: Ubuntu 16.04
• Firebase SDK version: 5.12
• Library version: 5.12
• Firebase Product: messaging

I want to send a push notification to a specific android notification channel, as described here:
https://developer.android.com/guide/topics/ui/notifiers/notifications.html#ManageChannels

Steps to reproduce:

Error: Invalid JSON payload received. Unknown name "android_channel_id" when calling admin.messaging ().send () with the following payload

let pushMessage = {
    notification: {
      title: title,
      body: body,
    },
    android: {
      "notification": {
        "title": title,
        "body": body,
        "sound": "mysound",
        "tag": "alerts",
        "icon": "myicon",
        "android_channel_id": "myalertchannel",
      }
    }

I've tried putting android_channel_id in several different objects of the payload and received the same error. I know that channels are supported because you can set the channel in the firebase console and I've confirmed my phone receive the notification. Am I missing something?

This is not supported in the backend REST API: https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages#AndroidConfig

SDK cannot support it until it's exposed in the REST interface. I have an internal bug tracking this request with the FCM team.

So what is the official way now to go about sending messages via node admin SDK now then?

We need to target API Level 26 and from what I understand, for notifications to be displayed, they need a set channel. Does anyone here have this working? How do I set the channel? Do I need to pin to an older version of the SDK that still allowed arbitrary keys (as suggested here)? Or what's the best way to make this work for now?

@hiranya911 are there any updates on the channel id? It looks like the legacy api has support for the channel_id(https://firebase.google.com/docs/cloud-messaging/http-server-ref), any reason why the new api doesn't?

I'd love a solution to this. We are using admin.messaging.sendToDevice and from what I can see we don't have a way to set a channel.

@skabber if you're using sendToDevice and set android_channel_id it works

Thanks @rstims android_channel_id does work when putting it in the notification part of the payload. I wonder why iOS payload doesn't support thread-id.

@hiranya911 Any internal updates?

[hiranya911]

This has been implemented. Will be included in the next release.

Thanks @rstims android_channel_id does work when putting it in the notification part of the payload. I wonder why iOS payload doesn't support thread-id.

Can you help me with a payload
I am using below payload for customizing the sound
{"notification":{"title":"YOUR TITLE","body":"YOUR BODY" , "android_channel_id": "homeapp1"} }
