HTTP Methods

HTTP methods consist of four methods: GET, POST, PUT, and DELETE.

GET

The HTTP GET method retrieves a resource. Provided that there is no error in retrieving the resource, the GET request will return the resource in either a XML or JSON format, along with an HTTP status code of 200. If there is an error, the request will typically return either a 404 (not found) or 400 (bad request) status code.

Put

The HTTP PUT method updates a resource. Once the resource is updated successfully on the server, then a 200 status code is returned. If there is an error, the request will typically return either a 404 (not found) or 400 (bad request) status code.

Post

The HTTP POST method creates a new resource. Once the new resource has been created successfully on the server, a 201 status code is returned in addition to a location header with a link to the new resource. If the new resource can't be created, typically a 400 status code is returned.

Delete

The HTTP DELETE method deletes an existing resource. If the resource has been successfully deleted, either a 200 status code or a 204 status code (no content) will be returned. If the resource can't be deleted, either a 400 or 404 status code will be returned.
