How to download JSON files from live feed?

[#1]

I have looked in to the following template by @Matt Burgess, which works fine for storing the data on my machine.

I have tried to save json file from https://thingspeak.com/channels/64519/feed.json.

From InvokeHTTP ---> PutFile is not receiving any data.

I am new to NIFI, i might be missing something.

@Shishir Saxena, I haven't done much. I have just used the code from here https://gist.github.com/mattyb149/6c09608b09ea07639e1a.

Changed the link. I have tried similar to your example as well, it is not working on my machine.
