- What are the common HTTP methods and status codes, and what does idempotent mean?
GET reads, POST creates or triggers an action, PUT replaces, PATCH partly updates and DELETE removes. A method is idempotent if repeating the same request leaves the server in the same state as doing it once - GET, PUT and DELETE are, POST is not. Status codes are grouped as 2xx success, 3xx redirect, 4xx client error and 5xx server error.
