    I'm not clear if using the same script on multiple domains or subdomain would mean the customer could initiate a chat on one website, and then browse to another, and keep their session?

    Scenario A: visitor initiates a chat at and then browse to which have the same widget script embedded. Will the session stay alive?

    Scenarion B: visitor initiates a chat at and then browse to  

    As we link our help center at support.<domain> to our main page at <domain>, I'd be curious to hear feedback if this is supported.

    Hi Joel,

    For non-authenticated visitors, Scenario A will work since the visitor cookie is tied to the domain and not the subdomain. 

    For Scenario B, it isn't supported for non-authenticated visitors. If you authenticate visitors server side, you will get cross domain support.

    To learn more about authenticated visitors, read the announcement post here:

    I need to set up 2 different chat widgets on 2 websites, in order to have different agents oversee different business units.


    I do not want top set up a brand new ZD account for the second website.


    Thank you
