Since the introduction of REST API v2 with eZ Publish 5.0, two authentication methods are supported: session, and basic.

• Session-based authentication is meant to be used for AJAX operations. It will let you re-use the visitor's session to execute operations with their permissions.
• Basic authentication is often used when writing cross-server procedures, when one remote application executes operations on one/several eZ Platform instances (remote publishing, maintenance, etc).

As of eZ Platform the default authentication method is Session-based as this is needed for UI.

Session based authentication

This authentication method requires a Session cookie to be sent with each request.

If this authentication method is used with a web browser, this session cookie is automatically available as soon as your visitor logs in. Add it as a cookie to your REST requests, and the user will be authenticated.

Logging in

It is also possible to create a session for the visitor if they aren't logged in yet. This is done by sending a POST request to /user/sessions. Logging out is done using a DELETE request on the same resource.

HTTP Basic authentication

To enable HTTP Basic authentication, you need to edit app/config/security.yml, and add/uncomment the following block. Note that this is enabled by default.

        ezpublish_rest:
            pattern: ^/api/ezp/v2
            stateless: true
            ezpublish_http_basic:
                realm: eZ Publish REST API

Basic authentication requires the username and password to be sent (username:password), based 64 encoded, with each request, as explained in RFC 2617.

Most HTTP client libraries as well as REST libraries do support this method one way or another.
