Resolve the identifier as a CORP

pragazzini

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.
