I have the syntax correct. I've been unable to create a new department. For testing on macbook, I've run: -- curl "http://<hostname here>/api/index.php?e=/Base/Department/&title='hi'&app='tickets'&type='public'" -d "title='hi'&app='tickets'&type='public'&apikey=<somthing>&salt=<something>&signature=<something>"; echo "" -- I've post the data in the post and in the URL just to make sure it gets through. No combination of app= and title= and type= has allowed me to create a department. Each time I receive the following: Invalid Module Specified. You can only create departments for tickets and livechat module. Please help!
