whmcs ssl on multisite, whmcs integration plugin

Hey guys

I am abit confused on how ssl for whmcs works with plugin. Does the ssl work for all whmcs on all wordpress sites integrated with the whmcs plugin
I have my main website, mysite.com,
I have my whmcs which is on mysite.com/whmcs

I the have a few subdomain subsites that are domain mapped, and the all use whmcs integration plugin. If i add ssl to mysite.com and mysite.com/whmcs how will this affect my subsites wuth regards to whmcs
