Message Persistence

PubNub's Message Persistence feature enables developers to store messages as they are published, and retrieve them at a later time.

Name	Description
Include Timetoken	Whether event dates time tokens should be included in response or not.
Count of Messages on Channels	The API is a history based API that simply does a mostly normal history operation but instead of returning the messages in a channel it returns the count of messages. Without actually calling history on those channels this API gives you the ability to say if there are messages in the chat channel you can go look at further.
Reverse	Traverse the timeline in reverse starting with the oldest message first.
Start End	Time token delimiting the start/end of time slice (exclusive) to pull messages from.
Count	Specifies the number of historical messages to return.
History with meta	The SDK has support to retrieve History with metadata
Fetch messages from storage with meta	This function fetches historical messages from multiple channels with metadata.
Fetch messages from storage with action flags	This function fetches historical messages from multiple channels with message action flags.

This function causes the client to create an open TCP socket to the PubNub Real-Time Network and begin listening for messages on a specified channel.

Name	Description
Subscribe to channels	Ability to subscribe to channels.
Subscribe to channel groups	Ability to subscribe to channel groups.
Subscribe to presence channels	Ability to subscribe to presence channels.

Filter Expression	Stream Filter allows a subscriber to apply a filter to only receive messages that satisfy the conditions of the filter. The message filter is set by the subscribing client(s) but it is applied on the server side thus preventing unwanted messages (those that do not meet the conditions of the filter) from reaching the subscriber.

App Context API User events listener	Has support to listen to User Events from App Context API.
App Context API Space events listener	Has support to listen to Space Events from App Context API.
