HTTP methods

GET: Retrieve data from a server only

HTTP GET won’t have payload or request body, just send URL only, it simply retrieves data

POST: Add data (create a new object) on the server

PUT: Update an existing object or resource in a server

DELETE: Delete data from a server

Remove is NOT an HTTP verb
