[[overview]]
= Overview
[[overview-http-verbs]]
== HTTP verbs
RESTful notes tries to adhere as closely as possible to standard HTTP and REST conventions in its
use of HTTP verbs.
|===
| Verb | Usage
| `GET`
| Used to retrieve a resource
| `POST`
| Used to create a new resource
| `PATCH`
| Used to update an existing resource, including partial updates
| `DELETE`
| Used to delete an existing resource
|===
RESTful notes tries to adhere as closely as possible to standard HTTP and REST conventions in its
use of HTTP status codes.
|===
| Status code | Usage
| `200 OK`
| The request completed successfully
| `201 Created`
| A new resource has been created successfully. The resource's URI is available from the response's
`Location` header
| `204 No Content`
| An update to an existing resource has been applied successfully
| `400 Bad Request`
| The request was malformed. The response body will include an error providing further information
| `404 Not Found`
| The requested resource did not exist
|===
[[overview-headers]]
== Headers
Every response has the following header(s):
include::{snippets}/headers-example/response-headers.adoc[]
[[overview-hypermedia]]
== Hypermedia
RESTful Notes uses hypermedia and resources include links to other resources in their
responses. Responses are in http://stateless.co/hal_specification.html[Hypertext Application
from resource to resource.
Language (HAL)] format. Links can be found beneath the `_links` key. Users of the API should
not create URIs themselves, instead they should use the above-described links to navigate
[[resources]]
= Resources
[[resources-index]]
== Index
The index provides the entry point into the service.
[[resources-index-access]]
=== Accessing the index
