SmartAPI Group

Hello Team,

Hi,

I am using the Angel One SmartAPI and noticed that the following 25 stocks are missing from the OpenAPIScripMaster file under NFO segment for the 30JUN2026 expiry:

ACC, APOLLOTYRE, ATGL, BALKRISIND, BERGEPAINT, COROMANDEL, ESCORTS, GUJGASLTD, HUDCO, IGL, IRB, IRCTC, JKCEMENT, JSL, LTIM, LTTS, M&MFIN, MRF, POONAWALLA, SJVN, TATACOMM, TATAMOTORS, TATATECH, TORNTPOWER, UBL

All of these are valid NSE F&O stocks, and their option contracts are active for this expiry. Without them in ScripMaster, I am unable to obtain their token IDs for API use.

Could you please look into this and add the missing entries?

Thank you.

@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
