Our context for discussion are APIs using HTTP protocol and using the infamous REST which is the software architecture design built to serve < b>network applications.

The most common application of REST is the World Wide Web itself, which used REST as the basis for the development of HTTP 1.1.

REST was first mentioned in the year 2000 by Roy Fielding in his PhD thesis in which he describes a software architecture design built to serve networked applications.

Mid 2000 to 2014 we can say that we had the first generation of APIs being applied on a large scale in various scenarios and technology sectors.

In 2009 one of the most popular tools for organizing and managing APIs was born, it was born as a unified Hub and in 2015 the open source project called Kong was finally launched and in 2019 it acquired nothing more, nothing less than the Insomnia API testing platform.
