Hi,
is it possible using DSS rest api to get the constituents of a chain ric, in this case 0#GEM.HK
Can i use HistoricalChainResolution?
at the moment running that i get
"message": "The user does not have permission to perform the requested operation."
So i wish to know if that could list the contituents.
If its not the case please let me know if there are other methods i could explore.
Thanks!

You can use try below and the chain will be expanded to constituents.
https://hosted.datascopeapi.reuters.com/RestApi/v1/Extractions/ExtractWithNotes
{
"ExtractionRequest": {
"@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.TermsAndConditionsExtractionRequest",
"ContentFieldNames": ["RIC"],
"IdentifierList": {
"@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",
"InstrumentIdentifiers": [{"Identifier": "0#GEM.HK","IdentifierType": "ChainRIC"}],
"ValidationOptions": null,
"UseUserPreferencesForValidationOptions": false
}
}
}
Historical Chain expansions are available only for Tick History product users, I assume you are DSS user hence you are getting this error. Please get in touch with your point of contact in Refinitiv to discuss the Tick History offering.
With regards to Tick History product, got it.
Are there any other method to retrieve the chain ric constituents using the DSS API?
Thanks!
