Buy with orderType Quote causes Missing UnderlyingQuote Error

[jekru]

POST https://www.wikifolio.com/api/virtualorder/placeorder has such a payload:

{
  "wikifolioId":"3f7f7343-a0a5-42ed-b038-839b63498c10",
  "underlyingIsin":"US0378331005",
  "amount":1,
  "buysell":"buy",
  "orderType":"quote",
  "limitPrice":null,
  "stopPrice":null,
  "takeProfitLimitPrice":null,
  "stopLossStopPrice":null,
  "stopLossLimitPrice":null,
  "validUntil":null,
  "quoteId":"42b12a32-4df0-4e58-92ae-81addbd7dc59"
}

We are not sending quoteId with the api request. That should be the problem. But where can we get this parameter?
Let's click on "Preis holen" an see what happens.

No new request is made, so there has to be some kind of conection already established because the parameter orderId is not static. Websockets? Yeah!

wss://www.wikifolio.com/de/de/signalr/connect?transport=webSockets&clientProtocol=[clientProtocol]&connectionToken=[connectionToken]&connectionData=[{"name":"livehub"},{"name":"quotehub"}]&tid=[tid]

The websocket message that is being sent looks like this:

{
    "A": [
        "ea8e9c3f-fb36-4a89-8cf9-f1bc3a116868",
        "US0378331005",
        "1",
        910
    ],
    "H": "quotehub",
    "I": 25,
    "M": "GetQuote",
}

A[0]: string := GUID (but not the orderId!)
A[1]: string := ISIN
A[2]: number := AMOUNT
A[3]: number := 910 (BUY) | 920 (SELL)
"I": number := INCREMENTING ID (since the connection was established)

The websocket response looks like this:

[
    {
        "H": "QuoteHub",
        "M": "quoteCallback",
        "A": [
            {
                "QuoteId": "f5fb9ff0-14d9-4c1f-ad38-c88f8c9c949c",
                "WaitForManuelResponse": false,
                "Ask": 122.41,
                "Bid": 122.2,
                "ValidityDuration": 3000,
                "Currency": "EUR"
            }
        ]
    }
]

We finally got the parameter "QuoteId" that we have to add to our json payload with the post request. That was the debugging/reverse engineering part, now the implementing part begins.
