200-301 - Automation and Programmability - Section 6.5

Describe characteristics of REST-based APIs (CRUD, HTTP verbs, and data encoding) and recognise the components of JSON-encoded data.

Describe a REST API as stateless HTTP calls that map CRUD operations to the GET, POST, PUT/PATCH, and DELETE verbs and return status codes signalling success or error. Recognise JSON structure - objects of key/value pairs, arrays, strings, numbers, booleans, and null - and parse a small JSON payload to read the value of a given key, the most common data-encoding format in network APIs.
