NameDescription
Parse TokenThe SDK supports Parse Token.
Set TokenThe SDK supports Set Token.

Channel Groups

Channel Groups allows PubNub developers to bundle thousands of channels into a group that can be identified by name. These Channel Groups can then be subscribed to, receiving data from the many backend-channels the channel group contains.
NameDescription
Add ChannelsAdd channel to a channel group.
Remove ChannelsRemove channel from channel group.
Remove Channels GroupsRemove channel groups.
List Channels In Channel GroupList all channels of a channel group.

Notify

Alerts from the SDK.
NameDescription
Request message count exceededWhen the number of messages arrived on a subscribe response are equal to or greater the number set in the init config, a new status message on the status callback, with the category PNRequestMessageCountExceededCategory, will be invoked.

Mobile Push Notifications

Mobile Push Notifications feature enables developers to bridge native PubNub publishing with third-party push notification services including Google Android Firebase Cloud Messaging (FCM) formerly known as Google Cloud Messaging (GCM) and Apple iOS Apple Push Notification Service (APNs).
NameDescription
Add Device To ChannelsEnables push notifications on provided set of channels.
Remove DeviceDisable push notifications from all channels which is registered.
List Channels From DeviceList all channels on which push notification has been enabled.
Remove Device From ChannelsDisable push notifications on provided set of channels.
APNS SupportSDK has support to send notifications using APNS.
APNS2 SupportSDK has support to send notifications using APNS2.
FCM SupportSDK has support to send notifications using FCM.

Presence

PubNub's Channel Presence empowers your applications to Track online and offline status of users and devices in realtime.
NameDescription
Here NowObtain information about the current state of a channel including a list of unique user IDs currently subscribed to the channel and the total occupancy count of the channel.
Where NowObtain information about the current list of a channels to which a UUID is subscribed.
Set StateSet state is used to set key/value pairs specific to a subscriber UUID.
Get StateGet state is used to get the key/value pairs specific to a subscriber UUID.
HeartbeatTimeout events are triggered when the server does not hear a heartbeat from the client within a default timeout time of 280 seconds.
Presence Delta IntervalsAfter a certain amount of occupants on a channel, the presence service stops sending individual join and leave events and instead starts sending interval notifications of people that join or leave. The amount at which delta kicks in is configurable on the admin panel.

Publish

Publish a message on a channel.
NameDescription
Store FlagAbility to skip message from storage.
Publish RAW JSONPublish JSON as is.
Publish with MetadataPublish extra meta with the request used for Message Filtering.
Publish using GET Publish using HTTP GET.
Publish using POSTPublish using HTTP POST.
Publish AsynchronouslyPublish the message asynchronously.
FireFire method used for publishing. When a message is sent using fire, it will not be replicated to other Points of Presence, it will remain at the originating Point of Presence, and is not eligible for archiving via the Message Persistence feature.
Replication FlagControls whether the message should be replicated across stores.
TTL per published messageOffer the ability to set a per message time to live in storage.

Message Persistence

PubNub's Message Persistence feature enables developers to store messages as they are published, and retrieve them at a later time.
NameDescription
Include TimetokenWhether event dates time tokens should be included in response or not.
Start EndTime token delimiting the start/end of time slice (exclusive) to pull messages from.
Count of Messages on ChannelsThe 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.
Fetch messages from storageThis function fetches historical messages from multiple channels.
Delete messages from storageRemoves the messages from the history of a specific channel.
CountSpecifies the number of historical messages to return.
History with metaThe SDK has support to retrieve History with metadata
Fetch messages from storage with metaThis function fetches historical messages from multiple channels with metadata.
Fetch messages from storage with action flagsThis function fetches historical messages from multiple channels with message action flags.

Time

Return a 17 digit precision Unix epoch from the server.
NameDescription
TimeThis function will return a 17 digit precision Unix epoch from the server.

Subscribe

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.
NameDescription
Subscribe to channelsAbility to subscribe to channels.
Subscribe to channel groupsAbility to subscribe to channel groups.
Subscribe to presence channelsAbility to subscribe to presence channels.
Subscribe to presence channel groupsAbility to subscribe to presence channel groups.
Subscribe with timetokenSubscribe with timetoken.
Wildcard subscribeWildcard subscribes allow the client to subscribe to multiple channels using wildcard. E.g., if you subscribe to a.* you will get all messages for a.b, a.c, a.x. The wildcarded * portion refers to any portion of the channel string name after the dot (.).
Filter ExpressionStream 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.
Publisher UUIDHas the publisher UUID of the published message.
Subscribe Message DedupeAutomatically dedupe duplicate messages.
Signal ListenerHas support to listen to Signal messages.
PubSub v2 compatibilityUses PubSub v2 to make subscribe calls.
Signal ListenerHas support to listen to Signal messages.
