Today is 16th September and my App apikey subscription exipres on 19th September. I have not yet subscribed for Historical API. At this time, If i subscribe for Historical API with 2000/- does it mean that i need to renew within 3 days once again for Historical API?
Only base subscription will expire. You will have to renew base subscription to use historical data API. The historical data API just requires base subscription to use but has independent subscription cycle.
