Custom Events in RelationKit can be used for a wide variety of things. Most use it to integrate tightly with their applications to send details when important things happen. For example, when a user signs up you can send an event to RelationKit, or when they upgrade or downgrade their billing plan in your app you can send that along with the plan they've moved to so you can see it in your sidebar.
Paired with custom attributes for customers, you can have all that data you need to make informed support decisions right inside RelationKit.
