The DSS API Reference Tree shows a wide range of query criteria for Futures and Options Search here: https://hosted.datascopeapi.reuters.com/RestApi.Help/Context/Operation?ctx=Search&opn=FuturesAndOptionsSearch
This gives an example C# and https query and response with JSON, but it doesn't seem to be interactive in any way. So, if I were to use the Ref Tree form to try to create an example, I would like to test valid search criteria values and see the formatted JSON payload to Post to DSS. I cannot get this detail. I also checked the C# example application Dss.Api.Examples.sln from here https://developers.thomsonreuters.com/datascope-select-dss/datascope-select-rest-api/downloads but this does not seem to include the Futures and Options code that is in the API Reference Tree.
Is there a resource that can help me be sure of a correctly constructed query with the large set of criteria that is available?
