Now I`m trying to build an web api to allow my customer to send the push messages (without accessing the firebase console). Studying the documentation here I realized that I've always to have a "to", meaning a group, topic or device id. My question is: can I send a message to all devices (like I can do in the

问题 I have been working on an Android application and my customer that will use it want to send notifications is there any way to send notifications from a Web UI other than firebase console? 回答1: There is currently no public API to send Firebase Notifications.

I'm using Postman for testing purposes and here's my body of my Postman Request: { "to" : (device token), "data" : { "body" : "great match!", "title" : "Portugal vs. Denmark", "content_available" : true, "priority" : "high", "sound": "default", "time_to_live":"2419200" } } And this is my onMessageReceived()

问题 I do like below in Swift 2. But It's not working in Swift 3. How Can I provide this? If someone explain this It would be great. didFinishLaunchingWithOptions let notificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil) UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings) application.registerForRemoteNotifications() and func application(application: UIApplication, didRegisterUserNotificationSettings

问题 When I send a notification to my Android device through the Firebase web interface, the notification doesn't peek down from the status bar. If I want to see the notification, I must swipe down.

This is not an issue if the notification arrives when the app is open because I can set the priority myself in my FirebaseMessagingService class: public class MyFirebaseMessagingService extends

问题 I'm trying to find out if there are any limitations for the topic names for FCM. Managed to find info about the number of topics (no limitations), but nothing like length of topic name or allowed characters. 回答1: Yes, not all characters are allowed, having space between words is not allowed in topic names.
