Zoho API Error Code 7019 when adding job.

Hello, I am following the documentation found here.

https://www.zoho.com/people/api/timesheet/adding-jobs.html

Regardless of how I try and post the data (including just using the example requests), I receive back the response

{'response': {'message': 'Error occurred', 'uri': '/api/forms/json/P_TimesheetJob/insertRecord', 'errors': {'code': 7019, 'message': 'Missing parameter(s) in the request'}, 'status': 1}}

for example.

header = {"Authorization": f"Zoho-oauthtoken {token}"}
response = requests.post("""https://people.zoho.com/people/api/forms/json/P_TimesheetJob/insertRecord?inputdata={"Job_Name":"Performance Analysis","StartDate":"01-Apr-2019","EndDate":"30Apr2019","Project":"469505000000267333","Assignees":"All","AssigneeHours":"20;20","AssigneeRate":"100;100","departmentIds":"469505000000133001"}""", headers=header).json()

Is the documentation missing something? Am I missing something? What parameter should I be including? The documentation mentions very little.
