How to get futures RIC and chain RIC by REST API

Hello @tao.su,

In addition to guidance from @gareth.teage ,

You may wish to create InstrumentList as empty per DSS .NET SDK examples:

var instrumentList = new InstrumentList { Name = "Instrument List Name" };
extractionsContext.InstrumentListOperations.Create(instrumentList);

And then append the identifiers to it:

IEnumerable<InstrumentIdentifier> appendIdentifiers = new[]
{
     new InstrumentIdentifier
    {
        Identifier = "SAGc1",
        IdentifierType = IdentifierType.Ric,
        UserDefinedIdentifier = "UserIdent5A"
    },
     new InstrumentIdentifier
    {
        Identifier = "0#SAG:",
        IdentifierType = IdentifierType.ChainRIC,
        UserDefinedIdentifier = "UserIdent5A"
    }
};
extractionsContext.InstrumentListOperations.AppendIdentifiers(instrumentList, appendIdentifiers, true);

Let us know how this works on your side?
