Seeing JDATA is missing or invalid errors below are two methods I tried using

Method 1:

def get_positions(susertoken, actid):    url = base_url +"PositionBook"    data = {"uid": "TEST18","actid": actid    }    payload = {"jData": json.dumps(data),"jKey": susertoken    }    headers = {'Content-Type': 'application/x-www-form-urlencoded'    }    response = requests.post(url, headers=headers, data=payload)    response_text = response.text    print(response_text)

Method 2:

def get_positions(susertoken, actid):    url = base_url+"PositionBook"    data = {"jData": '{"uid":"TEST18", "actid":"'+ actid +'"}',"jKey": susertoken    }    payload = "jData="+json.dumps(data)    headers = {'Content-Type': 'application/json'    }    response = requests.request("POST", url, headers=headers, data=payload)    response_json = response.json()    print(response_json)

API, I am using is here - https://shoonya.com/api-documentation#positions-booklogin is successful and susertoken and actid are correct.
