should i have something like this, if i want to parse with ArduinoJson library?
or like this:

how can i get "char json[]" in arduino ide skech?
i've tried to do it like in StringExample, but i have a lot of errors with libraries.

I think you did over-complexify your code. Also I'm seeing some undefined code not present in WiFiClient class, such as client.setTimeout() and client.find(). Where this code comes from ? Where are you getting the client.response ?
