Hey @monty_dabas ,

Here is the request structure for fetching the option chain data:

Option Chain
dhan.option_chain(
under_security_id=13, # Nifty
under_exchange_segment=“IDX_I”,
expiry=“2025-09-30”
)

You may also refer our library: GitHub - dhan-oss/DhanHQ-py: The official Python client for communicating with the Dhan API.

Additionally to fetch security id you may use https://images.dhan.co/api-data/api-scrip-master-detailed.csv
