Problems with opening INSTANT (QUOTE) order.

Hello, I have a problem with opening INSTANT (QUOTE) order on CFD account. Request (version:2), which I tried to open INSTANT order is pair EUR / USD :
{
"epic": "CS.D.EURUSD.CFD.IP",
"expiry": "DFB",
"direction": "SELL",
"size": "1",
"orderType": "QUOTE",
"level": "1.09911",
"guaranteedStop": "false",
"stopLevel": null,
"stopDistance": null,
"trailingStop": "false",
"trailingStopIncrement": null,
"forceOpen": "true",
"limitLevel": null,
"limitDistance": null,
"quoteId": "L1:CS.D.EURUSD.CFD.IP",
"currencyCode": "USD"
}

Get an error:
HTTP 400
status: error

{
"errorCode": "invalid.input"
}

I have a suspicion that I filled in the field not properly "quoteId": " L1: CS.D.EURUSD.CFD.IP " (Lightstreamer price quote identifier)
There is not written anywhere in the documentation where I can get the value of this field. I tried options: «EURUSD», «L1: CS.D.EURUSD.CFD.IP», «CS.D.EURUSD.CFD.IP». But the result is still an error.
Please write where I can learn what values should be written in the «quoteId». Or if you can give me an example of a request to open INSTANT order.
