If you would want your emails to contain “Task Transition Labels” like “Accept”, “Reject”. The standard CCI Url provided by IWOV is not sufficient. Based on the CC interface you are allowing the user to transition here are the URL’s to task transition
CC Professional
http://servername/iw-cc/command/iw.ccpro.task_details_transition_task?
done%5fpage=/iw-cc/teamsite/common/refresh%5fparent%5fand%5fclose%5fwindow.html&
transition=Accept&taskid=xxxx&full_redirect=true&do_transition=true
CC Standard
http://servername/iw-cc/command/iw.ccstd.task_details_transition_task?
done%5fpage=/iw-cc/teamsite/common/refresh%5fparent%5fand%5fclose%5fwindow.html&

Hope this helps.
