How to reply to thread via API

How to reply to thread via API

We have built a webapp for our customers that uses the Zoho Desk API to enable each customer to view their full list of tickets, view individual tickets and raise new tickets.

The Zoho Desk API doesn't have the ability to reply to a ticket/thread. Replies only seem to be possible via email or social media channels, both of which won't work for us: https://desk.zoho.com/DeskAPIDocument#Threads

Fully integrated support is a key feature of our webapp and without the ability to reply to a tick/thread we are prevented from rolling our webapp out fully.

Has anyone figured a workaround for this? Do Zoho plan to update their API to allow replies via webapps?

Many thanks
