Where can I get form_token?

Question

symfony

I display the form through symphony and when sending, I see, in addition to the filter_form [ezxform_token] form fields,
in another place I need to send the same form with Ajax. i do

var form = {
            "filter_form[name]": "blabla",
            "filter_form[type]": 0,
            ....
        };

when I submit $form->getErrors() returns me that the token is missing. where can i get it? display the form through
{{ form_label(form.name) }}
{{ form_errors(form.name) }}
{{ form_widget(form.name) }}
for the Ajax version there is no possibility
and what is its meaning at all if the session cookie is passed in the request
