Read notes from potential

Read notes from potential

Hi,
I just started with Zoho API so bare with me if this is obvious.

I want to be able to read notes from Potential object. 
I use this API  https://crm.zoho.com/crm/private/json/Potentials/getRecordById 
with selectColumn=All
It looks like API returns only top level fields.
Is there a way to get notes from the Potential and also is there a way to post a new note with API ?

Thanks
Albert
