Can I use multiple calendarID's with the google calendar api?

function listUpcomingEvents() {
        gapi.client.calendar.events.list({
          'calendarId': 'calenderID',
          'timeMin': (new Date()).toISOString(),
          'showDeleted': false,
          'singleEvents': true,
          'maxResults': 10,
          'orderBy': 'startTime'
        }).then(function(response) {
          var events = response.result.items;
          appendPre('Afspraken:');

          if (events.length > 0) {
            for (i = 0; i < events.length; i++) {
              var event = events[i];
              var when = event.start.dateTime;
              if (!when) {
                when = event.start.date;
              }
              appendPre(event.summary + ' (' + when + ')')
            }
          } else {
            appendPre('Geen afspraken vandaag');
          }
        });
      }
