Getting started
The activity stream service offers developers the ability to log, group, and render activity related to actions taken by site members:
The activity stream data can be retrieved using the $core_v2_activityStory Widget Extension, ActivityStories In-Process API Service, and Activity Story REST Endpoints.
New activity stories can be created by creating plugins implementing the IActivityStoryType Plugin Type interface. Activity story type plugins can define when messages are logged, how they're grouped, and how they're rendered.
