Data service SOAP operation has one parameter. How do I pass this parameter to the callout mediator?

Callout source code:

<?xml version="1.0" encoding="UTF-8"?>
<callout action="urn:getVendorsOperation"
    serviceURL="http://...:8280/services/myService/" xmlns="http://ws.apache.org/ns/synapse">
    <source type="envelope"/>
    <target key="response"/>
</callout>

the parameter:

<?xml version="1.0" encoding="UTF-8"?>
<property expression="get-property('uri.var.filterQuery')"
    name="filterQuery" scope="default" type="STRING" xmlns="http://ws.apache.org/ns/synapse"/>

UPD: WSDL FILE: http://...:8280/services/myService?wsdl https://drive.google.com/file/d/1JLpIhHO_Jbk2bSWNodudnyG_X8fXUuCy/view?usp=sharing

When you have Data Services - it creates webservice for which you should create appropriate request. In body / payload you use that parameter to get data back from request. What should the request look like? You can see by using wsdl. http://...:8280/services/myService?wsdl and there can be handy tool like SoapUI for generate body of that request. If you are using WSO2EI i recommend use DSS in local transport, it has better performance and not exposing it through http.

The documentation is not recommend using calloutMediator and it say is better to use callMediator.
