beginnerREST Fundamentals
What is the difference between GET and POST in a REST API?
GET requests data and should never change server state — it's safe, idempotent, cacheable, and its parameters typically appear in the URL query string, which limits length and exposes them in logs/browser history. POST sends data in the request body to create a resource or trigger an action, is not idempotent (calling it twice may create two resources), and is not cached by default.
