Create your GCM Sender ID and Server Key for Chrome Push easily

Before we talk how to generate your GCM Sender ID and GCM Server Key, let us take a quick shot at answering these questions.

What Is GCM Service?

Google Cloud Messaging is a free service that enables developers to send messages between GCM servers and client apps. This includes downstream messages from GCM servers to client's app, and upstream messages from client apps to GCM servers. Starting May, Google Cloud Messaging Platform is being replaced by Firebase Cloud Messaging.

Before 2014, GCM could only be used to send downstream messages (cloud-to-device) via HTTP. A GCM message sent with the HTTP API can be sent up to 1000 users, requiring multiple messages for large numbers of users. The new API offers an alternate method using XMPP, the GCM Cloud Connection Server. The CCS allows for a constant connection to Google's GCM servers and messages to be sent at the max wire speed. Google throttles this speed to be 4,000 messages per second at maximum, per connection; with a 10-connection maximum. When using all 10 connections you can send 40,000 messages per second. A key difference is that messages sent using Google's CCS is one message per device, rather than messages with multiple recipients.

Some key features of this Google Cloud Messaging Server are-

  • Versatile Messaging Target
  • Downstream Messaging
  • Upstream Messaging

What is Firebase Cloud Messaging?

Firebase Cloud Messaging is the new and evolved version of GCM. Firebase comes with lot of new features along with the obvious reliability and scalable GCM infrastructure. Read more about Firebase here.

What is the use of Server Key?

Server Key is the key saved on the app server that provides the app server authorized access to Google services. As a recommended practice, you should never include the API key anywhere in your client code.

What is the difference between GCM sender ID and FCM sender ID?

Google Cloud Messaging (GCM) Sender ID: A unique numerical value which is created when you configure your Project  in the Google Developers Console/ Google Cloud Console. The Project Number is GCM Sender ID and this is used in the registration process to identify an app server that is permitted to send messages to the client app.

Firebase Cloud Messaging / FCM Sender ID: Equivalent of Google Cloud Messaging (GCM) Sender ID. Accessible under the Firebase > Project > Settings > Cloud Messaging tab.

What are chrome push notifications?

Chrome web push notifications are clickable messages that are sent to Chrome browser  on your user's device. These modifications can only be sent to your subscribed users. In order to get these notifications, the subscribers do not have to be on your website. your users can easily subscribe to these notifications on mobile, desktop and tablet.
