I have an issue getting data when app goes in background. I'm using Firebase Cloud functions and I think something I didn't code correctly in NodeJS. I have tried many examples and solutions like putting:
content_available: true and priority: 'high' but nothing seems to work. I have to note that:
Notifications are arriving in background and foreground but I can read data from notification in foreground but data is not fetched in background. So there is NO notifications data in background even it is displayed with sound and alert.
I think I'm doing something wrong in data payload so here is my NodeJS method:
var message = {
token: tokenID,
notification: {
title: 'ChatApplication',
body: `${myUsername} send you a message`,
},
android: {
ttl: 3600 * 1000,
notification: {
icon: 'default',
sound: 'default',
click_action: "com.yupi.chatapplication.messaging"
},
data: {
from_user: user_id,
title: 'ChatApplication',
body: `${myUsername} send you a message`
},
},
apns: {
payload: {
aps: {
alert: {
title: 'ChatApplication',
body: `${myUsername} send you a message`
},
badge: 1,
sound: 'default',
content_available: true,
mutable_content: true,
priority: 'high'
},
},
},
};
return admin.messaging().send(message)
.then((response) => {
// Response is a message ID string.
return console.log('Successfully sent message:', response);
})
.catch((error) => {
return console.log('Error sending message:', error);
});
The right field names for the Node.js SDK should be contentAvailable and mutableContent: https://firebase.google.com/docs/reference/admin/node/admin.messaging.Aps

I am sending data only messages from a Firebase Function to a React Native app.
It works on Android, but it not works on iOS.
As specified here https://rnfirebase.io/messaging/usage#data-only-messages
my code for sending a message is the following:
var payload = {
data: {
//my app data
},
apns: {
payload: {
aps: {
contentAvailable: true,
priority: 'high',
},
},
headers: {
'apns-push-type': 'background',
'apns-priority': '5',
'apns-topic': 'com.xxxx.xxxx', //my app bundle id
},
},
tokens: tokens
};
const response = await admin.messaging().sendMulticast(payload);
The response has success=true, so the code is working.
In my iOS app I have this handler:
const setMessages = useCallback(async (remoteMessage: any) => {
console.log('A new FCM message arrived!', JSON.stringify(remoteMessage));
});
useEffect(() => {
const unsubscribe = messaging().onMessage(setMessages);
return unsubscribe;
}, []);
As I said before, it works on Android. In iOS the callback is never triggered.
I am pretty sure I setup the iOS app correctly:
- I can receive notification-only messages in iOS
- I can generate the fcm token
We are developing with flutter for both android and iOS in a mobile application. We have been on a problem for about 2 months and we could not solve it. The problem is;
When we click on the notification we sent, no action is taken on the iOS side and a black screen appears. This system, which works smoothly on the Android side, does not work on the iOS side. After some research we got here: https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages
We made an edit according to this link, but the notifications still do not work properly on the iOS side.
This is the message code we sent.
const message = {
token: token,
notification: {
title: username,
body: lastMessage,
click_action: "FLUTTER_NOTIFICATION_CLICK",
},
data: {
specificPageRouteId: lastSender.toString(),
chatId: chatId.toString(),
notificationType: "chat",
messageType: messageType,
click_action: "FLUTTER_NOTIFICATION_CLICK",
},
};
There are not working, the above is also not sending the notification correctly. But the main problem is the click problem in the incoming notification.
const message = {
token: token,
notification: {
title: username,
body: lastMessage,
},
data: {
specificPageRouteId: lastSender.toString(),
chatId: chatId.toString(),
notificationType: "chat",
messageType: messageType,
click_action: "FLUTTER_NOTIFICATION_CLICK",
},
};
Is there anyone who can help us with this?
Yes we have resolve this issue. The problem was on the firebase side. It got fixed when we used the new API. I think the new one is not very stable.
admin.messaging().sendToDevice( tokens,
{
notification: {
title: title,
body: body,
},
data: {
click_action: "FLUTTER_NOTIFICATION_CLICK",
notificationType: "TYPE",
},
},
{
content_available: true,
priority: "high",
}
);
This code works.
I'm sending data-only message from Cloud functions
I tried this solution: https://github.com/FirebaseExtended/flutterfire/issues/3395#issuecomment-683973108
Here are the option sendings from Cloud Functions:
{
android: {
priority: "high",
},
apns: {
payload: {
aps: {
contentAvailable: true,
},
},
headers: {
"apns-push-type": "background",
"apns-priority": "5",
"apns-topic": "io.flutter.plugins.firebase.messaging", // bundle identifier
},
},
}
And here the code which handle messages. (I want to create a notification from the client not from the server)
const AndroidNotificationChannel channel = AndroidNotificationChannel(
'high_importance_channel',
'High Importance Notifications',
'This channel is used for important notifications.',
importance: Importance.max,
);
class BackgroundHandler {
static const IOSNotificationDetails iosNotificationDetails =
IOSNotificationDetails(subtitle: 'notification');
static final AndroidNotificationDetails androidNotificationDetails =
AndroidNotificationDetails(channel.id, channel.name, channel.description);
}
FirebaseMessaging.onMessage.listen((RemoteMessage message) {
print('It works');
print(message);
FlutterLocalNotificationsPlugin().show(0, 'notification', 'new notification', NotificationDetails(android: BackgroundHandler.androidNotificationDetails,
iOS: BackgroundHandler.iosNotificationDetails));
NotificationManager.handleNotificationData(message.data);
});
On Android it works perfectly and it works even with notification, but nothing happens with data only messages.
I know this question have been asked many times but none of the answers work for me. Some of the questions dont even have an answer.
I am try to bundle or group similar notifications on ios. I am using FCM Cloud Functions to trigger notifications.
Following are the methods i tried by
const payload = {
notification: {
title: "Your medical history is updated" + Math.random(),
tag: "MedicalHistory",
},
data: {
click_action: "FLUTTER_NOTIFICATION_CLICK",
sound: "default",
status: "done",
},
};
const patchedPayload = Object.assign({}, payload, {
apns: {
headers: {
"apns-collapse-id": "MedicalHistory",
},
},
});
const options = {
priority: "high",
collapseKey: "MedicalHistory",
};
await admin
.messaging()
.sendToDevice("MY_TOKEN", patchedPayload, options);
The above code does not work
const payload = {
notification: {
title: "Your medical history is updated" + Math.random(),
tag: "MedicalHistory",
},
data: {
click_action: "FLUTTER_NOTIFICATION_CLICK",
sound: "default",
status: "done",
},
apns: {
headers: {
"apns-collapse-id": "MedicalHistory",
},
},
};
const options = {
priority: "high",
collapseKey: "MedicalHistory",
};
await admin
.messaging()
.sendToDevice("MY_TOKEN", payload, options);
This does not work as well.
I dont understand where to put the apns-collapse-id. The cloud functions sample also does not show this. Neither i could find doc with code on this
I recommend using the latest send function from the firebase-admin lib, usage described here.
It seems to work fine and somewhat easier to apply.
An example of a message with android/ios specific headers:
// common data for both platforms
const notification = {
title: 'You liked!',
body: 'You really liked something...',
}
const fcmToken = '...'
// android specific headers
const android = {
collapseKey: '0'
}
// ios specific headers
const apns = {
headers: {
"apns-collapse-id": '0'
}
}
// final message
const message = {
token: fcmToken,
notification: notification,
android: android,
apns: apns,
}
// send message
admin.messaging().send(message).catch(err => console.error(err));
I am trying to send notification from Node.js server to an ios application. It seems working if I send notification from Firebase console, but isn't working if try from my node.js server using firebase-admin sdk.
I followed tutorial from https://firebase.google.com/docs/cloud-messaging/admin/send-messages.
One thing I do not understand is the response after sending notification seems working. I get below response.
{
"results": [
{
"messageId": "0:1511109840587284%a63b4c28f9fd7ecd"
}
],
"canonicalRegistrationTokenCount": 0,
"failureCount": 0,
"successCount": 1,
"multicastId": 7436388871122493000
}
Does anyone know what I am doing wrong?
-- Edit
Here is the code that sends the notification. admin is the firebase-admin instance.
router.post('/notify', (req, res) => {
admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
databaseURL: "<database>.firebaseio.com"
});
var registrationTokens = [
'tokenFromIosApp'
];
var payload = {
data : {
body : 'TEST'
}
};
admin.messaging().sendToDevice(registrationTokens, payload)
.then((response) => {
console.log('Sent successfully.\n');
console.log(response);
res.status(statusCodes.Ok);
res.json(response);
})
.catch((error) => {
console.log('Sent failed.\n');
console.log(error);
res.status(statusCodes.InternalServerError);
res.json(error);
});
});
To send a notification, the payload must use the notification key:
var payload = {
notification: {
title: 'My Title',
body : 'TEST'
}
};
