Hi,
I am using java library to use kite connect APIs and getting following exception .
Please let me know what is my mistake?

This error comes at following line of code:

User user = kiteConnect.generateSession(REQUEST_TOKEN, API_SECRET);

REQUEST_TOKEN is my request token which i got through below url by giving my api_key:
https://kite.trade/connect/login?v=3&api_key=

and API_SECRET i got from my https://developers.kite.trade/apps section

Can you check what is the java version you are using?
We use java 1.8.0_121.
This doesn't seem like a javakiteconnect error, this is something related to setup.

I have fixed this issue.Sujith, Please let me know how credits works ? it is based on number of APIs hits i make to kite connect? or it is fixed for a month irrespective of the calls i make to Kite connect from my system in a month.

Sujith, I need historical data for 15 min candles for NIFTY50 AND nifty bank for last 2-3 years (whatever duration is available at zerodha) ? is it avaliable? i am using kite connect java library.I want to make sure before subscribing for HISTORICAL data APIs.

@sujith Hi Sujith, Please respond as i have to subscribe for Kite Historical subscription only if NIFTY and BANK NIFTY index 15 min candle data for 2-3 years are available. From the links you had provided i can get to know about API request/response but not about indexes for which i can get data as i have seen in forum for some index it is not avaiable.
So please confirm for NIFTY 50 and NIFTY Bank indexes regarding 15 min candle historical data for 2-3 years.
Please specifiy the indexes for which i will get intraday candle historical data for 2- 3 years.

Yes,NIFTY 50 and NIFTY BANK Index Intraday data is available from 2015. We do provide historical data for major indices.
