Activity Feeds

Activity feeds show social activity within your app. Set up feed rules to automatically create feed items when users track specific events.

How it works

1. Admin creates feed rules that map engagement events to feed actions
2. When a user tracks a matching event, a feed item is created automatically
3. Users can browse their feed to see friends' activity

Feed rules

A feed rule has:

• source_event — the engagement event that triggers feed item creation
• action — the action string in the feed item (e.g., "reached_streak_milestone")
• target_type — optional target type for context

Example rule

When a user tracks streak_milestone, create a feed item with action reached_streak_milestone:

{
  "source_event": "streak_milestone",
  "action": "reached_streak_milestone",
  "target_type": "streak"
}
