So it's integrated. Now, how on earth can a customer submit a ticket using WhatsApp? I am not able to install this number on my phone. Do they need to log in to Zoho Desk? to interact?
If you have configured the WhatsApp Instant messaging for your portal, the customer can initiate a chat from their own WhatsApp number which will be created as a ticket in Zoho Desk as per the configuration that you have configured.
