REST APIs
"In this video, I explain the fundamentals of REST-based APIs, a key topic in the CCNA 200-301 exam. We start by understanding what an API is and how it enables communication between network devices and applications. Then, we dive into the core principles of RESTful APIs, including CRUD operations (Create, Read, Update, Delete) and HTTP verbs like GET, POST, PUT, and DELETE.
I also cover URI structure, common HTTP response codes, and different authentication methods such as basic authentication and token-based access. Finally, we wrap up with a hands-on demo using Postman, showing how to make an API call and interpret the response — bringing the theory to life in a practical example.
