REST Responses¶
Response code¶
The following list of available HTTP response status codes gives an overview of the meaning of each code. For code details per resource, see the REST API reference.
Code | Message | Description |
---|---|---|
200 |
OK | The resource has been found. |
201 |
Created | The request to create a new item has succeeded. The response Location header indicates where you can find the created item. |
204 |
No Content | The request has succeeded and there is no additional information in the response header or body (for example when publishing or deleting). |
301 |
Moved Permanently | The resource shouldn't be accessed this way. The response Location header indicates the proper way. |
307 |
Temporary Redirect | The resource is available at another URL considered as its main. The response Location header indicates this main URL. |
400 |
Bad Request | The input (payload) doesn't have the proper schema for the resource. |
401 |
Unauthorized | The user doesn't have the permission to make this request. |
403 |
Forbidden | The user has the permission but action can't be performed because of Repository logic (for example, when trying to create an item with an already existing ID or identifier, when attempting to update a version in another state than draft). |
404 |
Not Found | The requested object (or a request data like the parent of a new item) hasn't been found. |
405 |
Method Not Allowed | The requested resource doesn't support the HTTP verb that was used. |
406 |
Not Acceptable | The request's Accept header isn't supported. |
409 |
Conflict | The request is in conflict with another part of the repository (for example, trying to create a new item with an identifier already used). |
415 |
Unsupported Media Type | The request payload media type doesn't match the media type specified in the request header. |
500 |
Internal Server Error | The server encountered an unexpected condition, usually an exception, which prevents it from fulfilling the request, like database down, permissions or configuration error. |
501 |
Not Implemented | Returned when the requested method hasn't yet been implemented. For Ibexa DXP, most of users, user groups, content items, locations and content types have been implemented. Some of their methods, and other features, may return a 501. |
Response headers¶
A resource's response may contain metadata in its HTTP headers.
Note
For information about the Allow
response header, see the OPTIONS
method.
Content-Type header¶
When a response contains an actual HTTP body, the Content-Type
header specifies what the body contains.
The Content-Type
header's value is a media type, like with the request Accept
and Content-Type
headers.
For example, the first following request without an Accept
header returns a default format indicated in the response Content-Type
header, while the second request shows that the response is in the requested format.

Accept-Patch header¶
When available, the Accept-Patch
tells how the received item could be modified with PATCH
.
The following examples also shows that the format (XML or JSON) is adapted:
1 |
|
1 2 3 |
|
1 2 |
|
1 2 3 |
|
Those example Accept-Path
headers above indicate that the content could be modified by sending a ContentUpdateStruct in XML or JSON.
Location header¶
For example, creating content and getting a content item's current version
both send a Location
header to provide you with the requested resource's ID.
Those particular headers generally match a specific list of HTTP response codes.
Location
is mainly sent alongside 201 Created
, 301 Moved permanently
, 307 Temporary redirect responses
.
In the following example, the content item's remote ID 34720ff636e1d4ce512f762dc638e4ac corresponds to the ID 52:
1 |
|
1 2 |
|
In the following example, an erroneous slash has been added to demonstrate the 301 case:
1 |
|
1 2 |
|
cURL can follow those redirections. On CLI, there is the --location
option (or its shorthand -L
).
In PHP, you can achieve the same effect with CURLOPT_FOLLOWLOCATION
.
The following command-line example follows the two redirections above and the Accept
header is propagated:
1 |
|
1 2 |

Cross-origin¶
Cross-Origin Resource Sharing (CORS) can allow the REST API to be reached from a page on another domain.
For more information about CORS, see WHATWG's CORS Protocol specification and Overview of CORS on developer.mozilla.org.
CORS support is provided by the third party nelmio/cors-bundle. You can read more about it in NelmioCorsBundle's README.
Using CORS isn't limited to REST API resources and can be used for any resource of the platform.
The CORS bundle adds an Access-Control-Allow-Origin
header to the response.
Configuration¶
To enable CORS, add regular expression for an allowed domain using the .env
variable CORS_ALLOW_ORIGIN
.
For example, to allow the JS test above to be executed alongside this page, you could add the following to an .env
file (like the .env.local
): CORS_ALLOW_ORIGIN=^https?://doc.ibexa.co
.
To add several domains, filter on URIs, or change the default (like not allowing all the methods), refer to NelmioCorsBundle Configuration Documentation to learn how to edit config/packages/nelmio_cors.yaml
.
Response body¶
The Response body is often a serialization in XML or JSON of an object as it could be retrieved using the Public PHP API.
For example, the resource /content/objects/52
with the Accept: application/vnd.ibexa.api.ContentInfo+xml
header returns a serialized version of a ContentInfo object.

The response body XML can contain two types of nodes:
- Final nodes that fully give an information as a scalar value
- Reference nodes which link to
href
where a new resource of a givenmedia-type
can be explored if you need to know more
