Auto-resolve support tickets and escalate the rest

Reported result

The source does not report measured outcomes, success rates, or resolution times. It only claims the workflow is operational and cost-effective at approximately $0.90/month for 50 tickets/day. No data on actual customer satisfaction or error rates is provided.

Human role

The original post does not say how a person stayed involved.

Limitations

Requires n8n, OpenAI API, SMTP, Google Sheets, and Slack credentials. Optional integrations include knowledge base and CRM APIs. The source does not specify error handling for API failures or hallucination safeguards. Human involvement is implied in escalation but not detailed in the workflow logic.

Try it

Act as an automation engineer. I need to replicate the n8n AI support agent workflow described in the source. Inputs: [Replace with your n8n instance URL], [OpenAI API Key], [SMTP Credentials], [Slack Bot Token], [Google Sheets ID], [Knowledge Base API Endpoint], [Order History API Endpoint]. Steps: 1. Create an n8n workflow starting with a Webhook node to receive ticket JSON. 2. Add parallel HTTP Request nodes to fetch data from the Knowledge Base and Order History APIs. 3. Insert an OpenAI node using GPT-4o-mini to classify the ticket (billing, technical, etc.), assign priority, detect sentiment, and draft a response. 4. Add an IF node to check if the AI confidence score is high enough to auto-resolve. 5. If true: Send an HTML email via SMTP, log to Google Sheets, and post to a general Slack channel. 6. If false: Route to specific Slack channels (#billing-support, #tech-support, etc.) including the AI draft and internal notes. Deliverables: A valid n8n workflow JSON file and a setup guide. Quality Check: Run a dry test with 3 sample tickets (one simple, one complex, one security-related). Verify correct routing and email formatting. Do not activate the workflow for live traffic until I confirm the test results.
