Place Bet

PinnacleBotBetting.py

def place_bet(base_url, username, password, bet, stake):
    
    url = base_url + "/v1/bets/place"
    b64str = base64.b64encode("{}:{}".format(username,password).encode('utf-8'))
    headers = {'Content-length' : '1',
               'Content-type' : 'application/json',
               'Authorization' : "Basic " + b64str.decode('utf-8')}

    data = {
            "uniqueRequestId":uuid.uuid4().hex,
            "acceptBetterLine": str(True),
            "stake": str(float(stake)),
            "winRiskStake":"RISK",
            "sportId":str(int(bet['sportId'])),
            "eventId":str(int(bet['eventId'])),            
            "lineId":str(int(bet['lineId'])),
            "periodNumber":str(int(bet['period'])),
            "betType":"MONEYLINE",
            "team":bet['team'],
            "oddsFormat":"DECIMAL"
    }

    req = ulib.Request(url, headers = headers)
    response = ulib.urlopen(req, json.dumps(data).encode("utf-8")).read().decode()
    response = json.loads(response)
    print("Bet status: " + response["status"])

Can you please shed some light on this: what is the difference in winRiskStake between WIN and RISK?
Also, what is the bet['period']? What period are we talking about here?
Since Pinnacle doesn't provide support for their API I'm struggling to find an answer. I hope you can help.
