REST API Guide¶
The REST API v2 introduced in Ibexa DXP allows you to interact with an Ibexa DXP installation using the HTTP protocol, following a REST interaction model.
REST API reference¶
See REST API reference for detailed information about REST API resources and endpoints.
For more information see a presentation about Ibexa DXP APIs.
Accessing the REST API¶
The REST API is available at the URI
/api/ezp/v2 . HTTPS is available as long as your server is properly configured. Refer to the Getting started with the REST API section below to start using the API.
The API provides a set of URIs, each of them identifying and providing access to operations on a certain resource. For instance, the URI
/content/objects/59 will allow you to interact with the Content item with ID 59, while
/content/types/1 will allow you to interact with the Content Type with ID 1.
It uses HTTP methods (
DELETE , etc.), as well as HTTP headers to specify the type of request. Depending on the used HTTP verb, different actions will be possible. Example:
||Provides you with data about Content item #2|
||Updates the Content item #2's metadata (section, main language, main location...)|
||Deletes Content item #2|
||Creates a copy of this Content|
Caution with custom HTTP verbs
Using custom HTTP verbs, those besides the standard (GET, POST, PUT, DELETE, OPTIONS, TRACE), can cause issues with several HTTP proxies, network firewall/security solutions and simpler web servers. To avoid issues with this REST API allows you to set these using a HTTP header instead using HTTP verb POST. Example:
Media type headers¶
On top of methods, HTTP request headers will allow you to personalize the request's behavior. On every resource, you can use the Accept header to indicate which format you want to communicate in, JSON or XML. This header is also used to specify the response type you want the server to send when multiple ones are available.
Accept: application/vnd.ez.api.Content+xmlto get Content (full data, fields included) as XML
Accept: application/vnd.ez.api.ContentInfo+jsonto get ContentInfo (metadata only) as JSON
Other headers will be used in HTTP requests for specifying: the siteaccess to interact with and authentication credentials.
Responses returned by the API will also use custom headers to indicate information about the executed operation.
Getting started with the REST API¶
No special preparations are necessary to use the REST API. As long as your Ibexa DXP is correctly configured, the REST API is available on your site using the URI
/api/ezp/v2/. If you have installed Ibexa DXP in a subfolder, prepend the path with this subfolder:
Please note that the
/api/ezp/v2 prefix will be used in all REST hrefs, but not in URIs.
As explained in more detail in the authentication page, two authentication methods are currently supported: session and basic. By default, session authentication is the active mode, it uses a session cookie. The alternative, basic auth authentication requires a login / password to be sent using basic HTTP authentication.
To enable basic auth based authentication, you need to edit
config/packages/security.yaml and uncomment the configuration block about REST

Testing the API¶
A standard web browser is not sufficient to fully test the API. You can, however, try opening the root resource with it, using the session authentication:
http://example.com/api/ezp/v2/. Depending on how your browser understands XML, it will either download the XML file, or open it in the browser.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
In order to test it, just save this code to some test.html file in the web folder of your Ibexa DXP installation. If you use the rewrite rules, don't forget to allow this file to be served directly.
If necessary, substitute
59 with the Content item ID of an item from your database. You will get the ContentInfo for item 59 in JSON encoding.
Note that by default, session authentication is used. This means that the session cookie will be transparently sent together with the request, and every AJAX call will have the same permissions as the currently logged in user.
