We need a solution that will:

- to keep certain cookies of the user who entered the site
- immediately redirect the user to another page with unique tags in the link (ClickID)
- to bind the received data is user-specific cookies to ClickID
- to upload the data (leads and their cost) from the program (via the API), and using ClickID compare them with those cookies users

The end result is a table with two columns: the value of the cookies, the cost of lead.

Desirable implementation on Wordpress.

The desired complexity estimate, willing to consider suggestions.
