Fetching BSE NSE Stock prices without personal user login

We are trying to create an internal application for live stock prices of BSE and NSE stocks. But we are not able to get the data without user web login. Is there any way we can get this data without personal user web login?

To access live stock data, you need to generate an access token as a valid Upstox customer, which involves a web login process.

Please refer to this document for detailed instructions: Upstox API Authentication.
