I have been using Market data feeds and orders API successfully since long time. Recently I tried connecting to Margin calculation API, but it gives wrong JSON error every time( bad request). I tried from my code, from CURL (same as given on website with current symbols), from POST MAN. It gives same error from every platform. Can you please forward me a working sample in Node/Javascript. I tried curl sample given here: https://kite.trade/docs/connect/v3/margins/ I tried margins/orders as well as margins/basket paths. Both give same error.
