Resolve the identifier as a CORP

Hi all,

I'm working with Refinitiv DataScope Select (DSS) and encountering a discrepancy between results returned via the DSS UI and those returned via the REST API.

What is working:

  • When I upload a list of ISINs in the DSS UI and run an immediate extraction with Terms & Conditions content fields (which are bond-specific), everything works fine.
  • The UI seems to correctly pick the CORP version of the identifier when needed.

What is failing

  • When I make the same request via the REST API, I sometimes get empty responses for certain identifiers.
  • After investigation, I found this is because some identifiers (like CA01921DAA33) have multiple instrument types, such as EQTY and CORP.
  • The API appears to resolve the identifier as an EQTY instrument by default, which does not have the CORP-specific content fields I'm requesting.

Is there a way to force the API to resolve the identifier as a CORP instrument in the request?

Here’s how my identifier currently looks in the payload:

{  "Identifier": "CA01921DAA33",  "IdentifierType": "Isin"}

I’ve tried playing around with the ValidationOptions (e.g., AllowPrimaryInstrumentOnly, AllowInactiveInstruments), but I haven’t found anything that solves this ambiguity reliably.

Any advice on how to explicitly target the CORP stream, either via an additional property or a workaround, would be much appreciated.

Thanks in advance!

    Thank you for reaching out to us.

    When using Isin, you can add the source parameter in the identifier. For example:

    { "Identifier": "CA01921DAA33", "IdentifierType": "Isin","Source":"EJV" }

    I tested it by importing this ISIN to DSS and it shows the following.

    It is the same exchange when I used this ISIN with the TermsAndConditionsExtractionRequest. 

    {
    
    "ExtractionRequest": {
    
        "@odata.type": "#DataScope.Select.Api.Extractions.ExtractionRequests.TermsAndConditionsExtractionRequest",
    
        "ContentFieldNames": [
    
            "RIC",
    
            "CUSIP",
    
            "ISIN",
    
            "SEDOL",
    
            "Issuer OrgID",
    
            "Currency Code",
    
            "Exchange Code"
    
        ],
    
        "IdentifierList": {
    
            "@odata.type": "#DataScope.Select.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",
    
            "InstrumentIdentifiers": [
    
                   { "Identifier": "CA01921DAA33", "IdentifierType": "Isin" }
    
            ]
    
        }
    
    }
    
}

     "Contents": [
    
        {
    
            "IdentifierType": "Isin",
    
            "Identifier": "CA01921DAA33",
    
            "RIC": "AAUCdbu.TO",
    
            "CUSIP": "01921DAA3",
    
            "ISIN": "CA01921DAA33",
    
            "SEDOL": "BQBDGK1",
    
            "Issuer OrgID": "122470344",
    
            "Currency Code": "USD",
          "Exchange Code": "TOR"
    
        }
    
    ],

    You may need to check the Source of CA01921DAA33 shown on the DSS Web GUI.

    Please share the full request message of the TermsAndConditionsExtractionRequest.
