Business roles. What an event means, not its name.
A business role is a small, fixed catalogue of meanings mapped to event definitions. The panel, funnels, ads ROAS and conversion destinations read the role, never the event name; renaming a product’s event breaks no screen.
How to map
Open the event in Data › Event schemas and pick it in the Business role field. An app maps its kayit_tamamlandi event to the signup role, for example; the “New sign-ups” card and the sign-up-to-payment funnel work from that role.
The default conversion roles are marked below; an app can change the set.
