I had been using the now deprecated HTTP version of FCM and have switched to the required OAuth version.

We are using Firebase Cloud Messaging API to send Push Notifications to app users.

Due to the Legacy Cloud Messaging API being deprecated, there were some changes made in our Java server in order to use the HTTP V1 API. The main change, since we already had the latest Firebase Admin SDK library, was for the batchImport endpoint (https://iid.googleapis.com/iid/v1:batchImport). We have been using this endpoint for exchanging APN Tokens with FCM Tokens, since many of our iOS apps are sending APN Tokens when registering for push.

I have written code to send push notifications using FCM. The user’s push token is stored in the database, and if the token differs from the app instance’s token, the token in the database is updated. The process works as follows: the token is retrieved from the database, and a POST request is made to:

I am using Firebase to send Web push notificationI have integration BigQuery with my Firebase project. Also created sync to export Web push notification logs into BigQuery dataset. Notification logs are getting synced but only event MESSAGE_DELIVERED is not exported in BigQuery.

I have a notification system that sends RSS feeds to subscribers.

I’m experiencing an issue with the Firebase Console where the Cloud Messaging section is stuck on loading. After inspecting the developer console, I found that an API call to the Identity Toolkit API is returning a 404 error.

I used Firebase cloud messaging before in another project with no issues, on this new project i am facing a strange behavior where the the firebase console essentially hangs in the project settings / cloud messaging tab

I’m using Firebase Cloud Messaging to send Daily notifications to iOS users who have a PWA app installed. I’ve found that for a given token, I can only successfully send 2 notifications. Beyond that the call will return a success (verified in the logs) but the user never gets the notification. Havent tested it on android yet to confirm if this is an iOS specific issue.

I have an react web app. I want to implement Push Notification functionality in it. Since Firebase has migrated from legacy to HTTP v1. I want to know how to implement http v1 api to send web push notification.Since http v1 require oauth access token so how should I achieve this to send notification.
