Hi kuzmany ,  
  
  
  
i saw a reply of yours to a user asking about how to check if a guest is already a contact :  
  
  
  
you had replied :

Quote:

If you have mautic on same domain like website, you are able to get lead id from cookie.  
$sessionId = $\_COOKIE;  
$leadId = $\_COOKIE[$sessionId];

  
Can you please explain a bit more . My mautic installation is under the same domain but when i copy-paste this code and echo $leadid i get no reply . Any hint ? Should i activate or pre-install anything before fetching this data?  
  
Thank you for your time !  
  
PS: the website is in WP and i use the wp-mautic tracking pixel.

Thanks for the quick reply ! I’m working in firefox and open the chrome for mautic . I had this conflict in previous step when i couldnt track my own moves .

Is there any other possible mistake i do ? I just copy-paste and use these two lines of code ?? no other API configuration etc ?

Thanks for your time and interrest

PS : i wrap them within a visual-composer div as raw php \<?php code ?\>
