How to use REST with Web Content Manager items | HCL Digital Experience

Different processes are used when items are created and updated by using REST.

Item types

A complete list of supported item types are documented here: REST Item Types.

Content representations

Atom entry documents
Each web content item has an associated Atom entry document. The entry document provides access to the common metadata properties of the item, such as title and description, along with links to related items, and access control information.
The default media type of an entry document is application/atom+xml. However, application/json representations can also be obtained. Entry documents can be retrieved by running an HTTP GET to the entry resource. Entry resource URIs can be obtained from:
  • The service document
  • Links in other entry documents
  • Links in feed documents
  • Using POC to resolve an ID
Example links to entry documents:
<link rel="edit" href="/wps/mycontenthandler/!ut/p/wcmrest/SiteArea/c6b00ee6-d628-4cbd-9e65-15c90f2093a6"/>
<link rel="parent" href="/wps/mycontenthandler/!ut/p/wcmrest/item/ae6a3632-a1b5-456a-866e-e9baab84fe29"/>
<link rel="library" href="/wps/mycontenthandler/!ut/p/wcmrest/item/54a68ca2-c550-4385-966f-b0b612147547"/>
Media resources
In addition to the entry document, most items also have a media resource that is associated with them. The media resource exists to store the content of the item, for example, HTML or an image. The media resource location is found in the edit-media link of an items entry document. Media resource URLs support HTTP GET and PUT.
<link rel="edit-media" type="text/html" 
href="/wps/mycontenthandler/!ut/p/wcmrest/PresentationTemplate/02da6e9d-20ca-4c54-ae4a-f1114fa8e948"/>

Content Negotiation

When a resource supports multiple representations with different content types, clients can use content negotiation to request a specific representation. For example, entry documents are available in application/atom+xml; type=entry and application/json. There are two ways a client can specify the media type that the client can accept:
HTTP Accept header
Accept: application/atom+xml
Request parameter mime-type
GET /wps/mycontenthandler/!ut/p/wcmrest/SiteArea/c6b00ee6-d628-4cbd-9e65-15c90f2093a6?mime-type=application%2Fjson HTTP/1.0
Note: The methods that are used to specify the accept type work for all supported media types as listed in Supported media types.

Item path

The path of a requested item can be included by specifying the options=item-path URL parameter. For example:


HTTP 1.1 GET /wps/mycontenthandler/wcmrest/SiteArea/c0b72020-10b7-4197-a436-62a1d94ce03f?options=item-path
