Set up messages

All PubNub-powered applications use messages, whether that’s a chat message, device sensor readings, GPS coordinates, or other type of data. All messages are sent in channels, and for a device or user to receive that message, they must join that channel by subscribing.

As well as receiving messages, you can also use channels for sending, retrieving, securing, deleting, augmenting, and more.
