Hi, I have couple of questions related to Access Token. 1) Can we get Refresh Token by passing Access Token because I've created automated system and everyday i need to Login to KiteApi for getting access token. So, instead of that can i get refresh token that way i don't need to log in to system again and again. Meaning i can automate the whole login process instead entering password manually. 2) What is Default Expiry time for access token ?
