how can i pass two interaction ticket number in HPSM rest url

Question

This is my Rest URL:

http://serviceIP:servicePort/SM/9/rest/interactions/TicketNumer1

It will return all information of TicketNumer1. How can i add TicketNumer2 into same URL and fetch both tickets information at same time? According to HPSM service document, I tried by putting comma(,) between tickets number but it didn't work.
