Hi @Ketan , @Pradeep_Jaiswar
Tell me one thing who is making these apis?

I am getting this response from your Websocket code “Full” mode.
Where is Market depth in this?

Hello @chapterMurphy,

We recommend using JSON files for fetching instruments to ensure consistency, as CSV files will soon be deprecated. This update is also noted on our Instruments Page | API Documentation.

Thank you.

Hello @chapterMurphy,

The instrument key (NSE_INDEX|Nifty 50) you’re using refers to an index, and indices are not directly traded on the exchange. However, if you provide a contract for this index, you will receive market depth data in the askQ and bidQ fields.

Here is a screenshot of the NSE_FO|58562 instrument key which is represents 26100 CE of 3rd OCT.
