We've implemented our VCC with Freshdesk;
I'm assuming you're talking about this implementation: https://docs.8x8.com/8x8WebHelp/virtual-contact-center-for-zoho-agent/Content/zoho/get-started.htm
We had a little trouble as the integration kept resetting itself (we had been using a dodgy URL) and our agents just stopped using it. We have the correct URL now and it works well; unfortunately the damage to reputation has been done and although all our guides are for logging the agents in via Freshdesk there's still a lot of agents who just don't.
The Zoho integration (in the link) doesn't look quite as smooth as the Freshdesk one but I'd guess that's due to Zoho rather than 8x8.
Generally - I don't like that the agents have to put in the URL and api token (in all the other Freshdesk apps this is handled by admin in app config) this puts an additional load onto agents and is a bit of a liability (if an agent were to misuse the api token)
