+This code is easy to spot in the url of the editor or the live form, for example, `forms.fillout.com/t/foAdHjd1Duus`.
 
 All embed components allow you to pass URL parameters using the optional `parameters` prop, and you can also use `inheritParameters` to make the form inherit the parameters from the host page's url.
