in DSS

I am trying to invoke below REST API and further below is the part Request body, where Identifiers are provided.

https://hosted.datascopeapi.reuters.com/RestApi/v1/Extractions/ExtractWithNotes

I am using template as -

"#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.IntradayPricingExtractionRequest"

I didn't get, what are these Identifiers, what is the meaning of "Ric", is there any standard list and format of these identifiers. Is there any link for such documentation, where I could get such information ?

"IdentifierList": {
"@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",
"InstrumentIdentifiers": [
  {
    "Identifier": "JPYUSD=R",
    "IdentifierType": "Ric",
    "UserDefinedIdentifier" : "JPY To USD Conversion"
  },
  {
    "Identifier": "INRUSD=R",
    "IdentifierType": "Ric",
    "UserDefinedIdentifier" : "Rupee To USD Conversion"
  }
]
},
"Condition": { "ScalableCurrency" : "true" }
}
}

    nikhil_godbole,

    What are identifiers and RICs

    An identifier uniquely identifies a financial instrument. Several naming conventions co-exist, they use different identifiers.

    RIC (Reuters Instrument Code) is one of them. A RIC identifies an instrument as well as the exchange it is traded on.

    Other popular identifiers are the ISIN (International Securities Identification Number), CUSIP, etc. Some of these (like the ISIN) identify an instrument but not the exchange.

    DSS supports several identifiers. To see their list you can use the REST API Reference Tree, use the dropdown for field IdentifierList to select InstrumentIdentifierList and then open up the dropdown for IdentifierType:

    That said, as our databases use the RIC as the main identifier, we usually recommend you convert whatever code you are using to RIC. This is explained in the ISIN to RIC conversion article.

    RIC list

    There is no list of RICs, it would be huge, and as instruments are created and deleted on a regular basis, it would never be up to date !

    You can find RICs using our Eikon product, if you have it.

    As an alternative, you can use the RIC Search tool (just ignore the other information tabs around this, they are for a different API, but the tool also applies to DSS); type in the name of a company and then drill down in the results to find what you are searching.
