Dear Author of the Zoho_Invoice Gem:
I am a very happy user of this gem -- thanks so much for making it available!
I hope you can help me with this question. Our Invoice records utilize Custom Fields, and I was trying to retrieve the values of these Custom Fields via the zoho_invoice gem utilities; however, I have not been able to figure out how to do that. Is there a way to do so? If yes, could you please share it with me? Or is this the limitation of the underlying Zoho Invoice XML API itself? I have sent an inquiry to their support, but have not heard back yet.
Thank you for your help.
Sincerely,
--Alex Sherstinsky
