An n8n workflow automation that uses OpenAI to draft customer support replies from incoming Webhook messages. The workflow extracts context and priority, generates an AI-powered response, and routes high-priority tickets to Slack #support-leads for human review. All drafted replies — both standard and escalated — are sent to agents via Gmail and logged to Google Sheets for quality tracking.
