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

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.

SOC 2 Type II

December 4, 2017 – PubNub, the company behind the world’s leading realtime Data Stream Network (DSN), today announced that it has successfully completed the Service Organization Control (SOC) 2 Type II audit, for privacy, confidentiality, security and availability, conducted by Frank, Rimerman + Co. LLP. This achievement provides customers with even more confidence in how PubNub manages realtime data across the globe.

As companies increasingly use outside vendors to perform activities that are core to their business operations and strategy, there is a need for more trust and transparency into cloud software providers’ operations, processes and results. PubNub received its SOC 2, Type II certification from the AICPA for meeting and adhering to the security, availability, confidentiality, and privacy standards established by its Service Organization Controls (SOC). By communicating the results of this audit, customers can be assured of their reliance on PubNub’s realtime infrastructure.
