@abinayakj Currently, api key cannot be changed or deleted, however app details can be modified.

@loki your API request snippet must be sending some incorrect data.

@subhash_indian No. Order book is flushed before the start of the next trading day. Behaviour is similar to the orders page you see on the app.

@deeeepak Unfortunately, we cannot help you in the debugging / improvement of the code.
Request you to take help from a professional developer for the same.

@virendramatic There has been no issue with the historical data api in recent past. Can you share your api request snippet for analysis?

@raman12 You can use market data API to get LTP.
Feed token is used in websocket and not in standard APIs.

@bhushank Secret key is created along with API key. You need to create an API key to get a secret key.

@deeeepak Some more details

@rathodjatin76 @archana If you want to get the data for the NIFTY 50 token, you can get the OLHCV of the index.
If you are wanting the data of the Nifty 50 futures, you unfortunately might not get it, as the data of expired contracts is not stored.

Symbol token for NIFTY 50 index = 99926000
