OPTIONS - Shows the available HTTP methods that the server supports. POST - When submitting data from client to server, this method is best used if the data to be passed is huge or if the data to be passed would be a new entry to the server database. GET - Get a specific (or set) of data from server to the client. PUT - Pretty much like POST, except that it is commonly used in updating the items which already exist in the database. DELETE - Method for deleting a data to the server. HEAD - Same as GET but it will only return HTTP Headers and no body.
