n8n Watch Repair Triage: Gemini Estimate, Gmail & HighLevel

Automatically triage watch repair requests—using Sightengine photo checks and Google Gemini estimates—then send updates via Gmail and GoHighLevel.

This n8n workflow, n8n Watch Repair Triage: Gemini Estimate, Gmail & HighLevel, turns incoming watch repair form submissions into structured repair tickets with an estimated price/turnaround and customer-ready email drafts—while logging everything to Google Sheets.

What this workflow does

• Receives a new repair request from an n8n form submission, including a required uploaded watch photo.
• Syncs customer details with GoHighLevel: normalizes the submitted information, then looks up the contact and creates/updates it if needed.
• Processes the photo: reattaches the upload as binary data, extracts basic image metadata, and generates a unique repair ticket ID with a submission timestamp.
• Checks photo authenticity using Sightengine to score whether the photo appears AI-generated, then labels the request with an authenticity status.
• Generates a structured estimate with Google Gemini (AI agent with structured output): classifies the issue, determines a price range and turnaround, flags whether manual review is needed, and drafts a short customer email.
• Logs the full ticket (AI outputs, review flags, and details) into a Google Sheets “Repair Tickets” worksheet.
• Sends emails via Gmail:
  • If manual review is required: emails the shop to review and acknowledges the customer.
  • Otherwise: emails the AI-generated estimate to the customer and notifies the shop the estimate was sent.

Use cases

• Watch repair shops that want automated triage from customer submissions.
• Automation engineers building an n8n form → AI estimate → CRM sync pipeline.
• SaaS operators needing reliable workflows with photo verification, structured AI outputs, and audit logs in Google Sheets.
