How to extract FX rates from DSS using Rest or SOAP

anilsumanth.yakkali

Hi,

I am looking to find a method or URL to extract the FX rates from TR DSS. Can anyone provide the WSDL location or Rest API Link which contains any method to extract FX rates from DSS. There is no clear blog available on this.

Thanks in Advance!

Regards,

Anil

What's your integration plan?

• FX list?
• Input data format? CSV or JSON?
  
• Which fields do you want? Rate/Last price only?
• The frequency of update? Daily?

The easiest solution would be writing a console application that fetches DSS's FX rate and updates exchange rates with SAP SDK. Then use Windows Task Scheduler to execute your program.

DSS has .NET SDK, and there are tutorials on DSS portal. You can follow the .Net SDK Tutorial 5 and change extraction request to IntradayPricingExtractionRequest and change fields to "Last Price".

You also need the RICs (Reuters Instrument Codes) of FXs that you want. You can use RIC search tool here.

For REST API, you can download DSS postman sample collections from here.

Then try tutorial 3b: request intraday data.

You can use FX RIC such as EUR= or JPY=

This is my sample request:

    "ContentFieldNames": [
      "RIC",
      "Ask Price",
      "Asset Type",
      "Bid Price",

      "Instrument ID",
      "Instrument ID Type",
      "Low Price",
      "Open Price",
      "Previous Close Date",
      "Previous Close Price",
      "Security Description",
      "Settlement Price",
      "Trade Date",
      "User Defined Identifier",
      "Volume"
    ],
    "IdentifierList": {
      "@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",  
      "InstrumentIdentifiers": [{
        "Identifier": "JPY=",
        "IdentifierType": "Ric"
      },{
        "Identifier": "EUR=",
        "IdentifierType": "Ric"
      }]
    },
    "Condition": {
    "ScalableCurrency": true
    }
  }
}

And this is the sample result:

For WSDL, you can find more information from this document.

However, it is advisable to use REST API.

Hello Warat,

Thanks for the reply.

My Integration plan is to fetch the FX rates from TR DSS and update in SAP. About frequency we are not yet finalized but planning to work with REST approach. For achieving this using REST I need the below points fulfilled:

1.What is the endpoint URL for fetching FX rates?

2. What is the request content format and where can I get that?

3.Any certificates need to be installed for SSL handshake?

4.What is the time limit for token expiry.

Thanks in advance!

Regards,

Anil

1. The endpoint URL is
   https://hosted.datascopeapi.reuters.com/RestApi/v1/Extractions/Extract
   But please do check out the tutorials first.
2. The request formats of every requests can be found here: DSS API Reference Tree. You need DSS account to login.
3. No SSL certificates needed.
4. 24 hours.
