Login without using username & password

[Hemanand]

Could you share how to implement login flow without using username, password & TOTP.. So more using oauth 2 kinda flow.

From doc, could see for oauth login url would be https://smartapi.angelbroking.com/publisher-login?api_key=xxx

which then redirects to the url mentioned in the app with auth_token & feed_token as query parameters.

As part of generate token api, we need refreshToken api as request paylod but how to get that ?

Could you share detailed steps how to implement this login flow ? Or smart api does not support such login flow ?
