n8n Chat Helpdesk Workflow: SoterAI Guard + Groq Routing

Guarded, AI-powered helpdesk chat in n8n—prompt injection defense + Groq routing

This n8n Chat Helpdesk Workflow accepts customer chat messages, protects them with SoterAI Guard (blocking unsafe prompts and redacting sensitive content), then routes requests to Groq-powered agents for knowledge-base answers, bug triage, or human escalation—returning a final guarded response.

What this workflow does

• Receives chat input via an n8n Chat Trigger and forwards the user text plus a session ID to SoterAI Input Guard.
• Blocks unsafe requests: if SoterAI flags the message as unsafe, the workflow formats a security incident event and responds that the request was blocked.
• Normalizes and classifies intent: if allowed, it uses the guarded/redacted version when available and classifies the request as bug report, human escalation, or general support.
• Bug reports: uses a Groq chat model to summarize the issue, tag severity, generate a simple bug ticket ID, and send a confirmation message.
• Escalations: uses a Groq chat model to draft an acknowledgement, generate a handoff ticket ID, and prepare a human follow-up message.
• General support: uses a Groq chat model and forces a Pinecone vector-store tool lookup to answer from the knowledge base.
• Redacts outputs: passes the drafted response through SoterAI Output Guard before returning the final message to the chat.

Use cases

• Protect a SaaS helpdesk against prompt injection while handling incoming support chats.
• Auto-triage bug reports with severity tagging and consistent ticket IDs.
• Route complex issues to human support with a structured handoff message.
• Answer FAQs using your Pinecone knowledge base with guarded LLM responses.
