The response will contain a complete list of dishes, with detailed information on each of them.

In case of an error, the XML document will not contain the RK7Reference nodes, the RK7QueryResult.ErrorText attribute will contain the error text.
To optimize lookup the reference caching, use the RK7QueryResult.XMLVersion attribute.

If there have been any changes in the menu guide reference since the previous request, the value of this attribute will be different from the previous one.

In response to the request, an XML document of the following form will be returned:

<RK7QueryResult ServerVersion="7.6.0.81" XmlVersion="243" NetName="CONF_MIDSERVER" Status="Ok" CMD="GetOrderMenu"
ErrorText="" DateTime="2019-12-30T11:37:25" WorkTime="0" Processed="1">
<PriceScale id="3" code="1" name="Основная"/>
<TradeGroup id="7" code="1" name="По умолчанию"/>
<Dishes>
<Item Ident="1000189" Price="100" quantity="3000"/>

<Item Ident="2003" ID="2003" Price="0"/>
<Item Ident="1000378" ID="1000378" Price="0"/>
</Modifiers>
</RK7QueryResult>

Error handling should work similar to the previous request.

For each of the positions, the cost per item in kopecks will be returned in the Price attribute. Price="100" - one — one ruble.
For the positions that have quantity restrictions, the quantity attribute will also be returned, indicating the remainder of the dish in thousandths. That is: quantity = "1000" - One — One serving.
To display a list of dishes available for order, you must select from the dish directory - reference (the first request, ) only those dishes that are in the order menu - (the second request).
