Latest Feature Releases

Introducing Firebase Cloud Messaging Support
As Google has announced the deprecation of their “Google Cloud Messaging” (GCM) service, PubNub has switched over to that service's replacement: Firebase Cloud Messaging Service. There is no expected customer impact due to this change. Configuration of the PubNub Push API, to use the new Firebase Cloud Messaging Service, is still done through the PubNub Admin Dashboard and overall feature behavior remains the same.
New Feature Release: Message Counts API
We're excited to announce the release of our new API – Message Counts – enabling the retrieval of message counts, on a per channel basis, and using a single API call, of messages published to multiple channels after a specified timestamp (time-token). This API is available in our REST API platform as well as in the following SDKs: Objective-C, Swift, Java, JavaScript, Go, Unity, Python, PHP. See here for more information.

Major Mobile Push Upgrades

PubNub now supports using the updated interface to the Apple notification service (APNS HTTP/2). We have fully implemented this new service as well as supporting several new features that it enables. You can now use tokens from your developer account instead of push certificates. This vastly simplifies the process of securing the connection - no more need to generate certificates, which is an error prone process. Simply specify your token using cut and paste.

This also provides the ability to send a single message to multiple different apps registered to your Apple developer account. The process to remove a device from the service when a user deletes an app from their device is now much faster, and several other benefits. It will be rolled out shortly to all users, but if you want to use it in the meantime please contact

Server side publishing

We added a new endpoint to reach our services for our large customers sending messages from their servers to be delivered to devices using the PubNub network. This provides a number of features and optimizations specifically for this use case. Contact your customer success team if you want to make use of this endpoint.
