WHMCS Integration Host ip url ect..

Is there a way to let someone upgrade to packages or addons that you have created in WHMCS from the Dashboard of there WordPress?

Also I am not sure what to put in the host fields My install is in an addon directory 814media.com/directory and when I hit save it takes the end off... I am getting error when trying to add short code!
