Hi @suraj_kulkarni,

The best resource to direct content-related questions is to the Thomson Reuters Helpdesk, which you can reach by either calling the Helpdesk number in your country, or following the link below: https://mytr.thomsonreuters.com/content/mytr/en/signin.html?

When using a market data API, you simply specify the instrument as part of the request. If you are planning on new development, you will need to use the strategic Elektron APIs which include quickstart and how to tutorials to request for data. The legacy SFC APIs are quite old and are only provided for care and maintenance for existing legacy projects.
