Hi @NITIN_27532851, It seems that the instrument_key query parameter contains incorrect values.
You are currently passing:
instrument_key=INFY
instrument_key=WIPRO
instrument_key=HDFC_BANK
Instead, please use the corresponding valid values:
instrument_key="NSE_EQ|INE009A01021"
instrument_key="NSE_EQ|INE075A01022"
instrument_key="NSE_EQ|INE040A01034"
If you are still facing the same issue, kindly share the cURL request for further investigation
Thanks
