Human-in-the-Loop Automation with n8n — Liam McGarrigle

What does it actually take to build an AI workflow that can do useful work without becoming a black box? This workshop shows how to build secure, human-in-the-loop automations in n8n, using a Gmail and Google Calendar management agent as the concrete example. Liam McGarrigle walks through how to wire it together with n8n's visual automation system and combine chat triggers, tools, credentials, approvals, and access control into a workflow that can actually be observed and controlled. The session also covers how to extend the agent beyond the demo, including Slack-based interaction, scheduled runs, sub-workflows, and specialized subagents for larger real-world automation systems.
