I'm using the following: /api/index.php?/Tickets/TicketCount/GetList&apikey='.$apiKey.'&salt='.$salt.'&signature='.$encodedSignature ...and that returns data for every department. I tried changing to: /api/index.php?/Tickets/TicketCount/Get?department%20id[]=1&department%20id[]=2&apikey='.$apiKey.'&salt='.$salt.'&signature='.$encodedSignature and I get a fusion error. The API docs don't have any good samples so any help would be appreciated =)
There is no way to get only a specific department statistics. You must analyze the output of GET /Tickets/TicketCount to find department which interests you.
