Setting Fcm Notification Priority - Azure Notification Hub

问题

I am trying to set High Priority on an Fcm Notification Payload in C# SDK in order to send it the a mobile application from the Back-End. Standing to the Fcm Documentation the Json Paylod should look like this:

{
  "message":{
    "topic":"subscriber-updates",
    "notification":{
      "body" : "This week's edition is now available.",
      "title" : "NewsMagazine.com",
    },
    "data" : {
      "volume" : "3.21.15",
      "contents" : "http://www.news-magazine.com/world-week/21659772"
    },
    "android":{
      "priority":"normal"
    },
    "apns":{
      "headers":{
        "apns-priority":"5"
      }
    },
    "webpush": {
      "headers": {
        "Urgency": "high"
      }
    }
  }
}

Found here

In my code i tried diffent ways to do that with the Azure SDK. 1

var result = await voipClient.SendFcmNativeNotificationAsync(payload, tag);

Putting as payload this json

{
   "data":{
      "key":"value"   
},
   "android":{
      "priority":"high"

}

var notification = new FcmNotification(payload);
notification.Headers.Add("android", "{\"priority\": \"high\"}");

Putting ad payload the one i posted before

In both cases i receive the notification with normal priority.

Do you know where i'm making mistakes?

If you look at Azure Notification Hub documentation you could get confused because it links to FCM documentation: FCM allows different ways to build the payload, Notification Hub is stricter.

You should send the following payload:

{
   "data":{
      "key1":"value1",
      "key2":"value2",

   },
  "priority":"high"
}

The payload you send to Notification Hub is in fact the "android" field inside the Firebase payload.

Note: The priority is set automatically to high by Notification Hub if you set the title inside the notification field as follow:

{
  "notification": {
    "title":"any title"
  }
}
