History with actions introduction

You can retrieve messages and the associated message actions. You can also just retrieve the message actions that were written in the given time interval. This can be used to retrieve all actions posted since the app went offline. Getting a list of message actions in a channel returns a list of actions sorted by the message action's timetoken from the oldest to the latest.

For more information, refer to Message Actions.

Message Actions vs. Message Reactions

Message Actions is the flexible, low-level API for adding any metadata to messages (read receipts, delivery confirmations, custom data), while Message Reactions specifically refers to using Message Actions for emoji/social reactions. In PubNub Core and Chat SDKs, the same underlying Message Actions API is referred to as Message Reactions when used for emoji reactions - it is the same functionality, just different terminology depending on the use case.
