Files API

September, 2020
PubNub’s product team is happy to announce the release of “Files”, to upload and share files (images, videos etc.) with anyone in your app. Before this release, our customers had to build their own integration with Amazon S3 or other cloud hosting services to share files. Now, developers get this feature out-of-the-box so they can ship their product faster to market.
Files adds new functionality to your chat application, allowing your team and your users to share images, videos, and files with others. Now, when you upload a file directly into your application, it'll appear instantly in your chat. Behind the scenes, files are uploaded to an external bucket and the URL is passed to the chat application. PubNub Files messages can also contain a user-defined text portion that can be used to set a caption or placeholder text to display alongside the file. Key Features Sharing Files - users can upload files from their client apps to an external bucket and share them as links with other users in a channel. Users can then download the files locally or display them directly on their apps. Encrypting Files - users can encrypt file data before it is uploaded from the client app so files can be shared privately and are secure. This is required for HIPAA compliance in telemedicine to share patient records and images securely. Triggers for Moderation - file messages trigger before/after functions so you can easily integrate with third-party image moderation services before files are shared with other users and keep chats clean and friendly for everyone. Manage Files - customers can list files, get files and delete files from the external bucket. These operations are protected by PAM to prevent abuse.

Objects 2.0

June, 2020
We’re happy to announce that PubNub has released a new version of Objects that provides easy-to-use and serverless storage for user metadata, channel metadata and channel memberships. Developers can now store data that is common to their applications without having to spin up additional backend infrastructure and services. Manage your data and build innovative, reliable, and scalable applications on PubNub using the new and improved Objects.

APNS2 Improvements

May, 2020
More explicit control of how push notifications are sent over via the Apple API.

We have updated the APNS2 feature to support:

  1. Explicit specification of Push type, e.g. set apns-push-type to background versus alert versus voip, etc. (full Apple spec is here
  2. Relaxation of the rules associated with Apple’s treatment of content-available property (you can read more about that at the same line). There was plenty of chatter out there around the ambiguous statements from Apple around what to do here and we have decided to take a path where we allow customers to construct push payloads that confirm to the yet-to-be-enforced rules, thereby ensuring no issues if and when Apple chooses to enforce the validation that they claim is in place, or to continue without changing, and deciding to do migration to the valid Apple-mandated payload at some point in the future.

NEW FEATURE: Functions On Interval Events

May, 2020
Scheduled periodic serverless functions. Now execute your logic on a periodic basis, for performing batch operations and aggregations. Read more about this at

Enhancement: Chat Typing Indicators

March, 2020
We’ve added now added Typing Indicators to the team chat application. The app shows typing events as users are typing a message in a conversation. These events are shared with all users in that conversation. As part of this release, we have also added support for Signals in the PubNub Redux Framework. Go checkout the new app on the chat docs.
