Full Definition
REST APIs are the dominant API style for modern network management. They use standard HTTP methods: GET (read), POST (create), PUT/PATCH (update), DELETE (remove). Data is typically exchanged in JSON or XML format. Cisco platforms like DNA Center, Meraki, and vManage expose REST APIs, allowing network automation scripts and tools to configure and monitor devices programmatically.
Exam Trap — Don't Get Fooled
REST APIs are stateless — each request contains all necessary information. The response status codes matter: 200 OK, 201 Created, 400 Bad Request, 401 Unauthorized, 404 Not Found, 500 Server Error.
