    r = req.body;
    items = JSON.parse(r.items);
    const tradeurl = r.tradeurl;
    let client = new SteamUser();
    let manager = new TradeOfferManager({
        "steam": client, // Polling every 30 seconds is fine since we get notifications from Steam
        "domain": "example.com", // Our domain is example.com
        "language": "en",
        "cancelTime":180000
    });
    let community = new SteamCommunity();
 
    // Steam logon options
    let logOnOptions = {
        "accountName": config.username,
        "password": config.password,
        "twoFactorCode": SteamTotp.getAuthCode(config.sharedSecret)
    };
 
    if (FS.existsSync('polldata.json')) {
        manager.pollData = JSON.parse(FS.readFileSync('polldata.json').toString('utf8'));
    }
 
    client.logOn(logOnOptions);
 
    client.on('loggedOn', function() {
        console.log("Logged into Steam");
    });

                return;
            }
 
            console.log("Got API key: " + manager.apiKey);
 
            // Get our inventory
