Hello @xds-support,
To extract all instruments from InstrumentList by list name, please use the two-step approach described in detail in this thread.
Does it work for you, do you run into an issue?
Alternatively, you can obtain the listId via itemId:
{{protocol}}{{host}}{{api}}Extractions/InstrumentListItems('itemId')/InstrumentListĀ
and then do the same step two as discussed in thread
{{protocol}}{{host}}{{api}}Extractions/InstrumentLists('{{listId}}')/ThomsonReuters.Dss.Api.Extractions.InstrumentListGetAllInstrumentsĀ
Is this what you are looking to do?
