by api, you mean tracking pixel or just the api?  
because i am facing the same issue and it merges the contacts  
[Link to a similar question](https://forum.mautic.org/t/tracking-site-which-one-can-log-out-from/4765)  
what I. want is that I have a normal website where i login and logout and it’s made in javascript.  
so what i do is everytime someone signs up, i use this function call

> mt(“send”, “pageview”, {…properties})

and it saves a cookie by the name mtc\_id and mautic\_device\_id.  
so, suppose i want to logout and sign in from some other id, it will pick the previous cookie and update the previous contact.  
so, i want to delete the cookie from my javascript website, but i am unable to do that because that cookie is set by my server say “panel.bumbl.it”  
so, is there any functionn that removes that cookie? which come from my server.
