Unity V4 Message Actions API Reference for Realtime Apps

Add or remove actions on published messages to build features like receipts, reactions, or to associate custom metadata to messages. Clients can subscribe to a channel to receive message action events on that channel. They can also fetch past message actions from PubNub Storage independently or when they fetch original messages.
