Part 3. Communication
One of the important aspects of many workflow solutions is the communication that occurs between applications, between clients and servers, and between the workflow and the host application. In this section, you'll learn how to use workflow activities to simplify and coordinate the various communication scenarios.

The same application will both send a request to another branch as well as respond to requests from other branches.
