grab chainric data through rest api

Hi,
We are trying to pull data associated to a specific chainRic, 0#SPX*.U, using a rest api GET command. We were hoping to pull either the specific identifiers associated to the chain or even better specific fields for each identifier in the chain for a specific date. Can you help us with an example GET command?
We have only been able to get the
https://hosted.datascopeapi.reuters.com/RestApi/v1/Search/HistoricalChainResolution uri to work for the 0#.SPX chainRic, and for some reason the 0#SPX*.U did not work when we swapped it out.
Any help is appreciated!
Thanks,
Will

To retrieve the constituents of the chain RIC, at specific dates, you may try HistoricalReference request:
{
"ExtractionRequest": {
"@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.HistoricalReferenceExtractionRequest",
"ContentFieldNames": [
"RIC",
"CUSIP",
"ISIN",
"SEDOL",
"Issuer OrgID",
"Exchange Code",
"Currency Code",
"Change Date"
],
"IdentifierList": {
"@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",
"InstrumentIdentifiers": [
{
"Identifier": "0#SPX*.U",
"IdentifierType": "ChainRIC"
}
],
"ValidationOptions": {"AllowHistoricalInstruments": true},
"UseUserPreferencesForValidationOptions": false
},
"Condition": {
"StartDate": "2017-09-01T00:00:00.000Z",
"EndDate": "2017-09-01T23:59:59.999Z"
}
}

Thanks for the response @zoya.farberov
I used your example, and the request is accepted but I'm getting an empty file. Here is the request with the headers:
The postsed data is exactly the same as above. Any thoughts as to why the file would return empty?
