Is there a way to add a category in the .json file?

[LoeizD]

Hello

I'm trying to add categories to my product.

The sample product doesn't include a category.
I've tried getting the metadata with curl -n https://api.turbosquid.com/api/drafts/ID of a product where I added a category manually through the web UI, but that json file doesn't show the categories either.

Are categories not supported by the api?
If they are how should I add it in the json to pass to the exe to publish?

Thank you
