[Plugin: Contact Form 7] Adding website tag

I’m trying to set up contact form in a widget, and everything works so far except if the user enters a website

The widget details are basically

name
email
website

submit

What syntax should I be using for website, so far nothing seems to work, though I receive both the name and email fields.

Thanks
