func getUsers(success: (SuccessHandler)? = nil,
                error: (ErrorHandler)? = nil,
                finished: (FinishedHandler)? = nil) {
    // Do stuff
  }

func getUser(success: (SuccessHandler)? = nil,
                error: (ErrorHandler)? = nil,
                finished: (FinishedHandler)? = nil) {
    // Do stuff
  }

func getInvitations(user: User, success: (SuccessHandler)? = nil,
               error: (ErrorHandler)? = nil,
               finished: (FinishedHandler)? = nil) {
    // Do stuff
  }
