Web-based APIs can, for the most part, be testing using this guide. Some elements are naturally client-side and therefore irrelevant to API testing.

I suggest that we create an article in section 3 or 4.1 that talks about how the guide can be used for API testing.

I further suggest that we review the existing articles to ensure that the language used is appropriate for web app and APIs alike, and determine where any additions might be needed where testing for the same issue on an API involves a different process.
