Event handling in custom modules

You can configure the handling of various system events in a custom module.

Event handler triggers a specific action in the system after an event has occurred. It can be useful when creating complex modules. For example, a handler can start a business process configured within a module when you have changed some fields in an app item.

You can adjust a handler to start a script or a business process, or to send a message about the occurred event to an external microservice.
