Zendesk is currently the only HITL integration. I am not sure if they are planning on adding more right now but it might come at a later point as its not as requested compared to other features.^ If you got some coding knowledge you could try and make your own integration for a free one. You can checkout their GitHub here https://github.com/botpress/botpress/tree/master The Zendesk GitHub here https://github.com/botpress/botpress/tree/master/integrations/zendesk Docs about making an integration here https://botpress.com/docs/developers/howTo/build-integration/ YouTube tutorial on making an integration here I think that is all you should need for making one.
