Event Handler (Buisness Logic) When Relationship is updated

How would I manage to track when a relationship on an object has been updated (objects added / removed) through the buisness logic? Is there an event handler like “Before / After update” for relationships?
Thank you in advance

Hi JImmi,

When a related object is added or removed to/from the parent object, it happens on the client side. The business logic can react to the API calls your app makes.

If you need special handling for the use-cases when a relationship is altered, you could use the custom events for that purpose:
