Section Number and Name: 
Chapter 2. General API Information

Describe the issue: 
Due to a security issue with ruby [0], updates were applied that now require an 'Accept' header in the http requests. It also sometimes will require a 'content-type' to be included. Without this, the curl will not return anything.

Work with Operations/Engineering to determine examples for the documentation.
