I am using RA Web Service Rest action and getting JSON response.
I am able to successfully parse and fetch my output.

But I wonder if we can pass VARA object value to JSON expression because every time I have to fetch value based on the value sits in VARA object.

I have tried passing the value via Promt Sets, still no luck.
