Overview of Channel Manager Events and Response Mechanisms
Introduction
Goal
Learn about the different channel manager events and the mechanisms through which they are broadcasted and responded to.
Background
CMS users perform operations on publication channels using the Channel Manager. Some operations may require additional validation and/or processing in a delivery tier implementation. For this purpose, certain channel 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 channel 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.
Overview of Events and Mechanisms
There are seven different channel manager events that get broadcasted using two different mechanisms.
The table below shows which events are broadcasted through which mechanism and provides links to detailed instructions and examples:
