How to correctly specify channel_id in FCM using cloud functions

Unfortunately, no answer yet. I am checking out postman, I hope I can use that to test quicker.
I manage to send a notification through my app, however, the notification always ends up in the silent notification of my phone, no sound, no vibration and no notification icon in the top left of the phone, only a notification in the drawer when I swipe down :(
In an attempt to fix / improve the situation I tried the following:
Create an android notification channel with id: high_importance_channel by using flutter_local_notifications package. The channel was created successful, because requesting an overview of the existing channels, showed the newly created channel (among the other channels). The new channel has importance: 5, enableVibration: true and playSound: true, so that should do the job.
Send a FCM through cloud functions with the following code:
const functions = require("firebase-functions");
const admin = require("firebase-admin");
admin.initializeApp();
exports.chatNotification = functions.firestore
.document('chats/{groupId}/chat/{chatId}')
.onCreate( async (snapshot, context) => {
const message = {
"notification": {
"title": "Message Received",
"body": "Text Message from " + fromUserName,
},
"tokens": registrationTokens,
"android": {
"notification": {
"channel_id": "high_importance_channel",
},
},
};
admin.messaging().sendMulticast(message)
.then((response) => {
console.log(response.successCount + ' messages were sent successfully');
});
}
But so far not luck, the notification still ends up in the silent notifications. What am I doing wrong?

There are 2 ways of doing it. Might work in your case.
Way 1:
var payload = {
notification: {
android_channel_id: 'AppChannel',
/*

*/
title: 'Push Notification Arrived!',
body: 'Using Cloud Functions',
sound: 'default',
},
data: {
route: '/someRoute',
},
};
try {
const response = await admin.messaging().
sendToDevice(deviceTokens, payload);
console.log('Notification sent succesfully.');
} catch (err) {
console.log('Error sending Notifications...');
console.log(err);
}
Way 2:
const message = {
/*
https://firebase.google.com/docs/reference/admin/node/firebase-admin.messaging.basemessage.md#basemessagenotification
*/
notification: {
title: 'Push Notification Arrived!',
body: 'Using Cloud Functions',
},
data: {
route: '/someRoute',
},
android: {
/*
https://firebase.google.com/docs/reference/admin/node/firebase-admin.messaging.androidnotification.md#androidnotificationbodylockey
*/
notification: {
channelId: "AppChannel",
priority: 'max',
defaultSound: 'true',
},
},
token: deviceTokens,
};
// https://firebase.google.com/docs/reference/admin/node/firebase-admin.messaging.messaging.md#messagingsend
admin.messaging().send(message)
.then((response) => {
// Response is a message ID string.
console.log('Successfully sent message:', response);
})
.catch((error) => {
console.log('Error sending message, for LOVEs sake:', error);
});

How to add click action when sending FCM notification from Node.js admin SDK to Flutter app?

I have a cloud function which executes this code to send the notification to the user, I am getting notification correctly but I want to navigate to a particular screen for that I have to add click action something like this.
clickAction: FLUTTER_NOTIFICATION_CLICK
I have tried to put this property in different lines of code but nothing seem to work, can someone please tell where should I put it exactly?
This is my index.js file!
const message = {
token: data['guestFcmToken'],
notification: {
title: `New message from ${data['hostName']}.`,
body: data['type'] === 'image' ? 'Photo' : data['lastMessage'],
},
data: {
showForegroundNotification: 'false',
screen: 'chat'
},
}
console.log('Sending message');
const response = await admin.messaging().send(message);
console.log(response);

You can add clickAction: 'FLUTTER_NOTIFICATION_CLICK' in the following way
message = {
token: data['guestFcmToken'],
notification: {
title: `New message from ${data['hostName']}.`,
body: data['type'] === 'image' ? 'Photo' : data['lastMessage'],
},
data: {
showForegroundNotification: 'false',
screen: 'chat'
},
android: {
notification: {
clickAction: 'FLUTTER_NOTIFICATION_CLICK',
},
}
};

How to add settings for Android in the message

I have a code that prepares and sends a notification to a mobile application
// Create the notification
const payload = {
notification: {
title: "Title",
body: "Body",
},
};
// Options
const options = {
contentAvailable: true,
priority: 'high'
};
admin
.messaging()
.sendToDevice(tokenSnapshot, payload, options)
.then(response => {
console.warn(">> Notification sent successfully: ", response);
return response;
})
.catch(error => {
console.warn(">> Notification sent failed: ", error);
});
I would like to add here information such as:
priority: 'max'
visibility: 'public'
These are features supported in Android
It is mentioned in the documentation that it exists.
But there is nothing mentioned how to use it
Can anyone give advice?
The purpose of this is to display Notifications on your phone when it is in the background

Firebase sending multiple push notifications instead of stacking or replacing

I am trying to have a previous push notification stack with the new one or replace it in the system tray for android.
I am not sure how to do this as the push notification is sending back both data and notification objects, and from what I understand the notification goes directly to the system tray. If so how do I stop the notification from appearing independently. Some users would get 5-10 notifications and it would keep pushing up.
EDIT:
I tried collapse_key but it still does not replace prior notifications with the same key... am I doing it wrong somehow here?
method: 'POST',
uri: 'https://gcm-http.googleapis.com/gcm/send',
headers: {
'Content-Type': 'application/json',
'Authorization': authorize //GOOGLE API KEY
},
body: JSON.stringify({
"registration_ids": [otherUserResult.reg_id],
"collapse_key": "follow",
"data": {
"notifyToUserId": to,
"notifyFromId": from,
"notifyMsg": msg,
"notifyItemPicture": itemPic,
"notifyItemName": itemName,
"notifyFromName": fromName,
"notifyType": type,
"dateNotified": dateNotified
},
"notification": {
"title": fromName,
"body": notifyMsg,
"icon" : "ic_pushnotify"
},
"priority": "high",
"content_available": true

For me worked when I included in my 'notification' 2 lines:
collapse_key: 'your_app_unique_string',
tag: 'your_app_unique_string'
So the full code would be:
var payload = {notification: {
title: "Mensaje de "+message.name,
body: message.text,
sound: "default",
collapse_key: 'charlero',
tag: 'charlero'
}
};

Cannot send push notification via Azure Mobile Service

I have setup a Mobile Service in Azure and connected it to my Android app. Through this app I am calling the Azure API to insert an object into a database table linked to the mobile service.
I have written the script that is executed before it gets inserted. That script is intended to send a push notification to another device.
Now the case is, the object gets inserted into table but no push notification is received. What could be wrong? How can i debug?
Here's my insert script:
function insert(item, user, request) {
var devices = tables.getTable('Devices');
var receiverHandle;
devices.where({userId: item.receiver}).read({
success: populateHandle
});
request.execute({
success: function() {
// Write to the response and then send the notification in the background
request.respond();
console.log(item);
push.gcm.send(item.handle, item, {
success: function(response) {
console.log('Push notification sent: ', response);
}, error: function(error) {
console.log('Error sending push notification: ', error);
}
});
}
});
function populateHandle(results){
receiverHandle = results[0].handle;
}
}
Although logs state successful delivery of push notification. I am not receiving it on my device.
Here is one of the logs:
Push notification sent: { isSuccessful: true, statusCode: 201, body: '', headers: { 'transfer-encoding': 'chunked', 'content-type': 'application/xml; charset=utf-8', server: 'Microsoft-HTTPAPI/2.0', date: 'Sun, 10 Aug 2014 15:01:52 GMT' }, md5: undefined }

Refer to Migrate a Mobile Service to use Notification Hubs.
Microsoft had been upgraded the Mobile Service, to push notifications powered by Notification Hubs. You will not be affected if you created the mobile service before the upgrade.
Base on the response { isSuccessful: true, statusCode: 201, body ... }, it indicate that your Mobile Service is the new version.
If you prefer to send push without Notification Hubs, don't use push.gcm.send, use the following code snippet instead.
var legacyGcm = require('dpush');
legacyGcm.send(your_GCM_APIKEY, regId, item, function (error, response) {
if (!error) {
// success code
} else {
// error handling
}
});
