How To Build An AI Customer Support Agent with n8n (free template)
Bart Slodyczka. The n8n workflow connects to help-desk products, drafts replies from retrieved material, and turns solved tickets into candidate knowledge-base content. Before using that ingestion pattern, add human approval, redact personal data and secrets, preserve the source ticket and content version as provenance, and run retrieval evaluations against a held-out ticket set.
AI Expert note
Kept despite the small channel because it exposes a useful ingestion decision for review: solved tickets should become candidate material, not trusted knowledge, until an authorised reviewer approves a redacted, sourced, versioned entry and retrieval tests pass.
What you should get from this
See how an n8n support workflow drafts retrieval-backed replies and proposes knowledge-base updates, then identify the controls needed before production use.
Watch or know first
Basic n8n familiarity and access to a helpdesk like Zendesk, Gorgias or Freshdesk.

Anthropic Academy
MCP is the protocol that's quietly replacing one-off tool integrations across the AI tooling ecosystem. Learn it from the source. By the end you'll have built and deployed your own MCP server, connected an LLM client to it, and understood why this standard is the closest thing the field has to USB-C.

DeepLearning.AIPractical Multi AI Agents and Advanced Use Cases with crewAI
João Moura (Founder, CrewAI)
Doubles as our sales and customer-support vertical pick and a genuinely practical agent-building course: you build an agentic sales pipeline (lead scoring, personalized outreach) and a customer-support data-insights pipeline as two of the five hands-on projects, taught by CrewAI's own founder. Requires basic Python, so it sits with our other builder-track courses rather than the no-code picks.
