He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - REST APIs use standard HTTP methods like GET (read), POST (create), PUT (replace), PATCH (partially update), and DELETE to manage network resources. - A critical exam trap is the difference between PUT, which replaces an entire resource, and PATCH, which performs a more efficient partial update. - HTTP status codes signal the outcome of an API request, such as 200 for success, 201 for resource creation, 401 for authentication failure, and 404 for a resource not found. - REST APIs are stateless, meaning every request must contain all necessary information, including an authentication token in the header. - Data payloads in modern network automation are typically formatted in JSON, a lightweight, human-readable key-value pair format.
