Facebook Lead Qualifier Agent
Comment webhooks analyzed, scored, and replied — with manager alerts for hot leads.
Overview
An n8n agent that listens to Facebook Page comment webhooks, classifies each comment for sentiment and lead quality, auto-replies when safe, and emails managers when a high-priority lead or negative comment needs a human.
Problem
Social comments mix greetings, spam, complaints, and real buying intent. Teams cannot read every thread instantly, and replying late — or missing a hot lead — costs conversions.
Solution
Built a webhook pipeline that validates Meta payloads, structures comment data, runs GPT analysis for sentiment, category, lead quality, and reply text, posts public replies via Graph API when appropriate, and routes payment-related or high-priority leads to Gmail alerts.
Architecture
n8n workflow with Meta webhook verification, conditional routing on comment events, OpenAI for structured JSON analysis, HTTP Request for Facebook reply API, and Gmail nodes for manager notifications on negative sentiment or qualified leads.
Workflow
- 01 Facebook comment webhook hits n8n
- 02 Filter valid new comments and map fields
- 03 OpenAI scores sentiment, lead quality, and draft reply
- 04 Auto-reply on Graph API when requires_reply is true
- 05 Email manager on negative comments or priority leads
Results
- · Comments classified before a human opens Facebook
- · Public replies sent for safe, on-brand interactions
- · High-priority leads surfaced to inbox immediately
- · Negative comments flagged instead of auto-replied
