Just wondering, do I even have to add that attribute in the HTML?

With any form element, including hidden type ones, only the name of the element is used to name the posted value.

You have to add the name attribute.

If you have

hidden_field_tag 'token', 'VUBJKB23UIVI1UU1VOBVI@'

in your view, you'll access the value in your controller with

params[:token]

Is that what you're asking?
