Social Realtime Events

A topic is a distinct path that must be constructed for each model to which you wish to subscribe in real-time. The SDK provides helper methods to create these topics for each model type. Each topic encompasses an events enum, which developers can select to subscribe to based on their business context and interests.

To subscribe to updates from a community or any content created within that community, the user must have the 'Member' status in that community. Once the user leaves the community, they will no longer receive real-time events.

COMMUNITY - subscription to changes of the community object
POSTS - subscription to changes of post objects in the community
