Hi @Aishwarya.s1

We have a tutorial on the DSS product page.

First, you could request a list of available fields from either /Extractions/GetValidContentFieldTypes or /Extractions/GetValidExtractionFieldNames end point.

GET "https://hosted.datascopeapi.reuters.com/RestApi/v1/Extractions/GetValidContentFieldTypes(ReportTemplateType=ThomsonReuters.Dss.Api.Extractions.ReportTemplates.ReportTemplateTypes'TermsAndConditions')"

GET "https://hosted.datascopeapi.reuters.com/RestApi/v1/Extractions/GetValidExtractionFieldNames(ReportTemplateType=ThomsonReuters.Dss.Api.Extractions.ReportTemplates.ReportTemplateTypes'TermsAndConditions')"

Once you choose the fields you want, you can just use the same IdentifierList from your HistoricalReference request if you want to request the same RIC chains.
