n8n Support Ticket Triage: GPT-4o + Pinecone RAG

Auto-triage your support tickets with GPT-4o + Pinecone RAG—then resolve or escalate

With this n8n Support Ticket Triage workflow, incoming support tickets are enriched with CRM context, classified using OpenAI Chat Completions (GPT-4o), searched against a Pinecone knowledge base, and either auto-resolved via your helpdesk API or escalated to Slack with clear status and analytics logging.

What this workflow does

• Receives tickets via webhook: A POST webhook ingests the support ticket payload.
• Normalizes + enriches context: The workflow standardizes incoming fields and retrieves customer history from your CRM over HTTP.
• Classifies the ticket with OpenAI: Uses OpenAI Chat Completions to determine category, urgency, sentiment, and KB-match confidence, then merges results with the ticket context.
• Notifies the team when it’s urgent: Critical/high-urgency tickets are routed to Slack, while the workflow continues for knowledge-base handling.
• Grounded retrieval with Pinecone RAG: Queries Pinecone for top matching knowledge base entries and uses OpenAI to draft a grounded response that states whether the issue can be resolved and at what confidence.
• Resolves or escalates: If the draft confidence is ≥ 0.8, it replies via the helpdesk API and marks the ticket resolved; otherwise it escalates to Slack.
• Updates status + logs analytics: The workflow updates ticket status in the helpdesk system and logs final ticket data to an internal analytics endpoint.

Use cases

• Reduce first-response time by auto-resolving tickets when Pinecone knowledge matches with high confidence.
• Send critical/high urgency alerts to Slack for immediate human attention.
• Improve support consistency by using GPT-4o classification + grounded KB responses.
