AI Agent for Facebook Page

Facebook pages miss customer inquiries at night and on weekends. Manual replies are slow, inconsistent, and require constant staffing — leading to lost leads and poor customer experience.

A 9-node n8n workflow that catches every Facebook message via Webhook, filters bot loops, reads a live Google Docs knowledge base, and replies instantly through an OpenAI-powered AI Agent with conversation memory.

1. 1🔗 Webhook — listens for every incoming Facebook Messenger message (GET/POST)
2. 2🔀 IF Node — blocks invalid requests and bot loop traffic on the true branch
3. 3📤 Respond to Webhook — acknowledges valid requests immediately
4. 4🔍 Filter — keeps only genuine customer messages, drops noise
5. 5📄 Get a Document — fetches live knowledge base from Google Docs (no hardcoding)
6. 6🤖 AI Agent — powered by OpenAI, reads the docs, crafts accurate replies
7. 7🧠 Simple Memory — maintains conversation context per user across messages
8. 8🌐 HTTP Request — sends the AI reply back to Facebook Messenger automatically

• 24/7 instant responses — even at 3AM, zero delays
• Zero missed customer inquiries or lost leads
• Knowledge base updated in Google Docs — no code changes needed
• Eliminated need for dedicated support staff for repetitive questions
