Overview of Experience Manager Events and Response Mechanisms



Learn about the different Experience manager events and the mechanisms through which they are broadcasted and responded to.


CMS users perform operations on publication channels using the Experience manager. Some operations may require additional validation and/or processing in a delivery tier implementation. For this purpose, certain Experience manager events are broadcasted. A delivery tier implementation can listen for such events and respond to them.

Due to historical reasons, two different mechanisms are used to broadcast and responds to events. This page provides an overview of all available Experience manager events and which event is broadcasted through which mechanism. Detailed instructions and examples are provided on separate pages, which are linked to in the text below.
