Please check below screenshots.

Please tell me am i missing something?
Or is anything changed? cause i was getting data earlier.
Please advise on this.

Hi @ANIRUDHA_31468087
You are sending the expiry date as 10th July, but Nifty Next 50 does not have an expiry on that day. To find the correct expiry date for Nifty Next 50, please refer to our Option Chain:

You can also check the official NSE website for reference:

Thanks!

Got it. thanks.
but is there any api to get updated weekly and monthly expiry days?
