Hi, I had bought kite api 2nd sep and historical api on 14th Sep 2017. 1st October 2017 my subscription has ended for kite api and historical api subscription also ended that day. I have bought again both APIs on 2nd Oct 2017. But Today I am getting subscription renewal alert for historical API. As per my current subscription both should end on 1st Nov 2017. Please Check and do needful.
It seems like you created a new App instead of renewing the old App.
You just got a reminder for renewing historical data subscription for your old App. You can ignore that.
If you had renewed your old App then you didn't have to subscribe for historical data till 14 October.
