{ "name": "Lumeor | AI ticket triage and routing", "nodes": [ { "parameters": { "content": "## AI ticket triage and routing (Zendesk)\n\nClassifies every new Zendesk ticket with Claude, validates the answer in code, writes tags, custom fields and priority back to the ticket, and posts urgent tickets to Slack.\n\n**Setup**\n1. Credentials: Anthropic API, Zendesk API (email + API token), Google Sheets OAuth2, Slack.\n2. In Zendesk, create a webhook to this workflow's production URL (POST, JSON) and a trigger on *Ticket is Created* with condition *Tags contains none of: ai_triaged*. Use this JSON body:\n`{\"ticket_id\":\"{{ticket.id}}\",\"subject\":\"{{ticket.title}}\",\"description\":\"{{ticket.description}}\",\"requester_email\":\"{{ticket.requester.email}}\",\"organization\":\"{{ticket.organization.name}}\",\"plan_tier\":\"{{ticket.organization.custom_fields.plan_tier}}\",\"tags\":\"{{ticket.tags}}\",\"channel\":\"{{ticket.via}}\"}`\n3. Edit the taxonomy and FIELD_IDS at the top of **Prepare classification** and **Validate and set priority**.\n4. Replace REPLACE_WITH_SHEET_ID and the two REPLACE_WITH_SLACK_CHANNEL_ID values.\n5. Leave SUGGEST_ONLY = true for the first week, then set it to false to let the AI set priority.\n\n`claude-haiku-5-5` is a cheaper option for high-volume, simple classification. Change the model in **Classify with Claude**.\n\nTemplate by Lumeor Studio, https://www.lumeor.studio/guides/ai-ticket-triage-and-routing/", "height": 640, "width": 460 }, "id": "1581fa07-11bc-4e4f-b4c1-101af8189404", "name": "About this template", "type": "n8n-nodes-base.stickyNote", "typeVersion": 1, "position": [ -520, 60 ] }, { "parameters": { "httpMethod": "POST", "path": "lumeor-ticket-triage", "responseMode": "onReceived", "options": {} }, "id": "21cd88d9-c75b-40c4-a8cf-8bd3dfb26f21", "name": "Zendesk ticket created", "type": "n8n-nodes-base.webhook", "typeVersion": 2, "position": [ 0, 300 ], "webhookId": "c7e21101-bdbd-4745-97b0-c07e11b84448" }, { "parameters": { "mode": "runOnceForAllItems", "jsCode": "// Your taxonomy.
