POST lead Identify params with Remote Asset Download URL

Hi

I am using Mautic with a custom CMS which handles its own assets.

Leads are added with mautic API

In order to track lead asset downloads, I added my assets to mautic as “remote url asset” and I’m making a request to the “remote url” in my custom CMS pages,

problem is:

How can I identify an authenticated user in CMS to match a lead in “remote url”?

As I understand Mautic uses a cookie to identify users, can I fetch the identitiy token for a user and append it with my request headers?
