I recently started using Kite trading API to automate trading. I went through the API documentation. I could understand the need for access token when placing orders and GTT. These operations will be with respect to the current logged in user. When we fetch market quotes and historical data, why we need access token? I am trying to build a system with queries the zerodha API to fetch market quotes periodically in a day. To build this, I need to a manual sign-in and then fetch access token daily. I want to collect data independently without any manual intervention. Could you please help me in this?
