Unable to pass variable from payload to url in python

I am trying to pass a params named ID in to a python api function from postman which will use the ID to call another api function inside the actual api

 

but the id field remains None in postman output

 

requests.exceptions.HTTPError: 401 Client Error: Unauthorized for url: https://api.xxx.com/api/v1/target/id/None/id?isidRequired=True

 

this is my code

 

@D.route('/Checkcontactinfo/', methods=['GET'])

def checkcontact():

id = request.args.get('id')

ivurl: str = f'{xxx}/id/{id}/id?'

payload: Dict[str, Union[bool, int]] = {'isIDRequired': True,

'id':id}

response = get_iv_response(url=ivurl, payload=payload)

ID_contact_totalresult: int = response.get('totalResults')

return id_contact_totalresult
