Configure Stateless Security Firewalls 

The Symfony framework allows for the creation of stateless firewalls. In this case, the security token is not serialized for a session.

However, when API calls are utilized in AJAX requests from the UI, the user’s token data from the current session must be used instead of the firewall credentials (e.g., WSSE headers). For this purpose, the firewall should have the context parameter with the context name that the system can use to authenticate the user.

For example:

            stateless: true
            context:   main
            # ...
