Answer 1

What I did was two extra steps:

1. convert the json to a string (usually a method called json.stringify or something similar depending on the language you program in)
2. convert the result of step 1 to hexadecimal
3. store the hexadecimal data in the stream through the publish call.

if you're doing all this in your terminal you need to use a different tool to first convert your json to a string, and then your string to hexadecimal

Answer 2

At the moment you can't store plain json in a stream, though I believe it's a feature planned for the 2.0 version. What you need to do is convert your json to hexadecimal data, and use the publish function to store it in a stream, look up the how this command works here, in the  "Publishing stream items" section.
