Error DH-905 on option chain or historical option endpoints usually triggers when the request payload is missing one of the mandatory contract parameters (like expiryCode, strike, or drvOptionType) or when an expired contract securityId is passed.

Check that you are passing the exact numeric securityId from the latest daily scrip master CSV along with exchangeSegment set to NSE_FNO. Which specific API endpoint are you calling here?

Hi @Basavraj_Advitot ,

We have made improvements to the handling and processing of expired options data to ensure more reliable data retrieval and efficient request processing. Please note that you can now fetch up to 1 day of data per API request.

To retrieve data for multiple days, please iterate over the required date range and make a separate API request for each day, while adhering to the applicable rate limits.

Kindly re-generate your access token and retry the request.
