This is a legacy article. To find up-to-date information, please read r_keeper 7 XML Interface.

Introduction

There are two ways of using an XML protocol: HTTP transport and win32dll buffers.

From the client’s point of view, the interface is the RK7XML.dll library that provides the following calls:

function CallRK7XMLRPC
function CallRK7XMLRPCToStream
procedure SetUseTempFileLimit
function GetDLLVersion
function CallRK7XMLRPC2
function CallRK7XMLRPCToStream2
function GetLastXMLResult
function GetLastXMLResultToStream
procedure SetCryptKey

See a detailed description in the file rk7xmli.pas

A version number can be checked through GetDLLVersion.

To start working, you should call SetCryptKey and indicate the session encryption key.

The idea is that this library is a transport layer for an XML protocol. It is enough to use one function, for example, CallRK7XMLRPCToStream2 that reads a query from the flow and returns its response to the flow (it is recommended to use the functions having number 2 as they support the extended functionality).

RKeeper 7 Setup to work over the HTTP Protocol

To work with an XML interface over HTTP, you should setup R-Keeper accordingly.

POS Server Setup

  1. Create a right for HTTP in the POS server properties, in the HTTP restrictionssection;
  2. In the HTTP serversection, specify the port through which the connection will be established (POS server ports and directory server ports must be different).

Directory Server Setup

  1. Create a right for HTTP in the POS server properties (or use an existing right) in the HTTP restrictionssection;
  2. In the HTTP serversection, specify the port through which the connection will be established (POS server ports and directory server ports must be different).

User Setup for Connection

  1. Create a user with administrator rights and name that user in Latin characters as Russian ones will not be accepted; 2. In the user’s role properties, check the previously created rule in the Object Privileges section

Starting from version 7.5.3, you can use the HTTPS interface, for example, through the wget:

C:\soft\gnuwin32here\bin\wget.exe --secure-protocol=TLSv1 --no-check-certificate --header="Content-Type: text/xml" --http-user=9006 --http-password=9006 --post-file=reqRestItemRK.xml https://127.0.0.1:777/rk7api/v0/xmlinterface.xml

or curl

curl  -k -u user:7 -i -X  POST -H "Content-Type: text/xml" -d @xml.txt "https://192.168.101.82:3355/rk7api/v0/xmlinterface.xml"

or otherwise. Please do not confuse the ports that connect to correspondent servers.

Making an Exchange

The exchange consists in commands (queries) and responses. Example of such command:

<?xml version="1.0" encoding="windows-1251"?>
<RK7Query>
  <RK7CMD CMD="GetSystemInfo"/>
</RK7Query>

response:

<?xml version="1.0" encoding="utf-8"?>
<RK7QueryResult ServerVersion="7.5.2.34" XmlVersion="66" Status="Ok" CMD="GetSystemInfo" ErrorText="" DateTime="2013-02-15T17:05:33" WorkTime="0" Processed="1">
	<SystemInfo SystemTime="3570109533742" ReqSysVer="2" NetName="TEST_RK7SRV_COUNT"/>
</RK7QueryResult>

Let’s try to obtain something more interesting such as a list of collections:

<?xml version="1.0" encoding="windows-1251"?>
<RK7Query>
<RK7CMD CMD="GetRefList"/>
</RK7Query>

response:

</RK7QueryResult>

Now let’s request a specific collection and look into working with filters through the example of this query.

When making the query:

<?xml version="1.0" encoding="windows-1251"?>
<RK7Query>
<RK7CMD CMD="GetRefData" RefName="AWARDSPENALTIESGROUPS"/>
</RK7Query>

the response will be:

<?xml version="1.0" encoding="utf-8"?>
<RK7QueryResult ServerVersion="7.5.2.34" XmlVersion="66" Status="Ok" CMD="GetRefData" ErrorText="" DateTime="2013-02-15T17:56:04" WorkTime="0" Processed="1">
	<RK7Reference ClassName="TAwardPenaltyGroups" Name="AWARDSPENALTIESGROUPS" MinIdent="1" MaxIdent="0" ViewRight="0" UpdateRight="0" ChildRight="0" DeleteRight="0" XMLExport="True" XMLMask="*" LeafCollectionCount="1">
		<Items>
			<Item Ident="0" ItemIdent="0" SourceIdent="0" GUIDString="{22149C1B-CC53-4EC4-A46C-5A23E512CC7A}" AssignChildsOnServer="False" MainParentIdent="0" ActiveHierarchy="False" Name="Все" AltName="All" Code="0" Status="rsDraft" editRight="0">

				</Childs>
			</Item>
		</Items>
	</RK7Reference>
</RK7QueryResult>

or, for example:

<?xml version="1.0" encoding="utf-8"?>
<RK7Query>
	<RK7CMD CMD="GetRefData" RefName="MenuItems"/>
</RK7Query>

The response will be the Menu Items collection (i. e. the menu directory):

Object Recording

Recording commands are supported only on the directory server.

Below there are minimum allowed sets of object attributes. A relevant directory should be read to obtain the list of all object attributes.

Recording logic is inserting or updating. GUIDString is considered the key attribute. Parent objects are linked through the MainParentGUID attribute. If some attributes are not filled in, they are ignored. If an attribute should have an empty value, please indicate «». Records are deleted by setting the rsDeleted status but in reality they are not deleted from the database.

Getting the Menu

<?xml version="1.0" encoding="utf-8"?>
<RK7Query>
    <RK7CMD CMD="GetRefData" RefName="MenuItems"/>
</RK7Query>

Inserting an Item

<?xml version="1.0" encoding="utf-8"?>

  <Order guid="{577FFA69-348A-41D7-810B-CF0A32489BE1}"/>

</RK7Query>

or by the visit+orderident combination:

 <?xml version="1.0" encoding="UTF-8"?>
<RK7Query>
 <RK7Command CMD="GetOrder">
  <Order visit="543555" ident="256"/>
 </RK7Command>
</RK7Query>

Creation of a New Order

To create a new order, the following query is necessary:

<?xml version="1.0" encoding="UTF-8"?>
<RK7Query>
 <RK7CMD CMD="CreateOrder">
  <Order persistentComment="100500">
   <Table code="1"/>
   <Waiter code="5"/>
   <Station id="15015"/>
   <GuestType id="1"/>
   <Guests>
    <Guest GuestLabel="1"/>
    <Guest GuestLabel="2"/>
    <Guest GuestLabel="3"/>
    <Guest GuestLabel="4"/>
    <Guest GuestLabel="5"/>
   </Guests>
  </Order>
 </RK7CMD>
</RK7Query>

The only mandatory parameter here is the table Parameters: PersistentComment is a savable comment to an order; Table is a table. Access is granted when indicating any of its fields: code, ident or guid. Similarly to all other parameters; Waiter is the waiter on whose behalf an order is created. If the Waiter is not specified, an order is created by the system; Station is the station; GuestType is a guest type; In the <Guests> section you indicate guests and enter their names. Once an empty order is created, the following response is sent:

<?xml version="1.0" encoding="utf-8"?>
<RK7QueryResult ServerVersion="7.5.3.182" XmlVersion="166" Status="Ok" CMD="CreateOrder" VisitID="356255787" OrderID="256" guid="{6002FD3A-68B6-4FC9-8EB1-D53A697C286C}" ErrorText="" DateTime="2014-11-19T18:23:04" WorkTime="30" Processed="1"/>

To continue working, this response must contain either the visit + orderid combination or the guid. In this example we use the visit + orderid key.

To fill an order, the following query is sent:

<?xml version="1.0" encoding="UTF-8"?>
<RK7Query>
 <RK7CMD CMD="SaveOrder">
  <Order visit="356255787" orderIdent="256"/>
  <Session>
   <Station id="15015"/>
   <Dish id="1043439" quantity="1000" price="0"/>
  </Session>
 </RK7CMD>
</RK7Query>

In the example the call is made by the key that is the visit + orderid field combination. The station is not a mandatory parameter so it can be omitted. Dishes are what is most interesting about this query. You can access them by their id, guid or code. The quantity is multiplied by 1000!!! The price is not a mandatory parameter.

To indicate a modifier, the following query is made:

<Dish id="1043439" quantity="1000" price="0">
 <Modi id="100" count="1" price="100"/>
 </Dish>

Access by the id, guid or code. The price is a non-mandatory parameter; count is in measurement units.

Creation of a Banquet Order

1.To create a banquet order, you should use the CreateOrderxml query.

Example of an XML query:

<?xml version="1.0" encoding="UTF-8"?>
<RK7Query>
<RK7CMD CMD="CreateOrder" openTime="2025-04-17T10:00:00" duration="T05:00:00" holder="OOO Plunder and Flee">
       <Table code="44"/>
       <Waiter code = "1"/>
</RK7CMD>
</RK7Query>

2. To get banquet order properties, you use the GetOrder query

<?xml version="1.0" encoding="UTF-8"?>
<RK7Query>
<RK7CMD CMD="GetOrder">
   <Order guid="{871891FB-FFC3-40D7-B2E0-4D30853E88EE}"/>
</RK7CMD>
</RK7Query>

3. To add dishes to an order, you use the SaveOrder query:

<?xml version="1.0" encoding="UTF-8"?>
<RK7Query>
<RK7CMD CMD="SaveOrder">
  <Order guid="{871891FB-FFC3-40D7-B2E0-4D30853E88EE}"/>

If the amount is not enough, an error will be returned because of insufficient funds.
