I am developing a Java Desktop Program(No UI). I have few questions: 1. Whenever I run my app, I manually go to https://kite.trade/connect/login?api_key=xyz and get the request token everytime. I don't think I am doing it correctly, because its a tedious task to fetch it everytime I run it. How to reuse the tokens or is there any better way of doing it? 2. I want to reuse the token so that I watch an FnO instrument ticker at an interval of 5 sec. 3. How frequently the instrument Id changes?
