I can't get timesheet formlinkname.

I need to get it for integrating with  a API using something like this :

https://people.zoho.com/people/api/forms/P_timesheet/records?authtoken= <token> &xmlData=<Request><Record><field name='JobName'>Client : ABC</field><field name='Hours'>6</field></Record></Request>

I used this : https://people.zoho.com/people/api/forms?authtoken=<token>

  "isVisible": "true",

                    "displayName": "Employee",

                    "componentId": "0000",

                    "iscustom": "false",

                    "formLinkName": "P_Employee"

                },

                {

                    "isVisible": "true",

                    "displayName": "Department",

                    "componentId": "0000",

                    "iscustom": "false",
