GHL Lost Deal Reason Analyzer with Google Gemini (n8n Workflow)

Automatically Detect Why Deals Go “Lost” in GoHighLevel—Using Google Gemini (with n8n)

When a GoHighLevel opportunity changes status to lost, this n8n workflow gathers the matching contact, opportunity, and conversation transcript, then uses Google Gemini to infer the primary lost reason and saves it as a note on the contact—so your team stops guessing.

What this workflow does

• Listens for GoHighLevel opportunity status changes via a POST webhook (“opportunity status change”).
• Retrieves the related GoHighLevel contact and stops if the contact record is missing.
• Fetches the opportunity and proceeds only when the opportunity status is lost and the contact IDs match.
• Searches GoHighLevel conversations for the same location and contact, downloads the messages for the first matching conversation, and builds a chronological transcript (ignoring non-message activity events).
• Checks transcript quality: continues only if there is more than one message.
• Uses an n8n AI Agent with Google Gemini (structured output) to generate:
  • a primary lost reason
  • a short summary
• Creates a sticky note (contact note) on the GoHighLevel contact containing the lost-deal analysis.

Use cases

• Identify recurring reasons deals are lost after a sales call or chat conversation.
• Improve follow-up sequences by capturing why prospects disengaged—automatically.
• Give support and sales visibility into lost opportunities without manual review.
