💡 Pro Tip — If you’ve run into Facebook’s Graph API permission restrictions, ScraperNode is a community node that scrapes pages, groups, posts, and comments directly — no app review needed.
Description
What Problem Does It Solve?
Customers often ask product questions or prices in comments.
Businesses waste time replying manually, leading to delays.
Some comments only need a short thank-you reply, while others need a detailed private response.
This workflow solves these by:
Replying with a friendly public comment.
Sending a private message with details when needed.
Handling compliments, complaints, and unclear comments in a consistent way.
How to Configure It
Facebook Setup
Connect your Facebook Page credentials in n8n.
Add the webhook URL from this workflow to your Facebook App/Webhook settings.
AI Setup
Add your Google Gemini API key (or swap for OpenAI/Claude).
The included prompt is generic — you can edit it to match your brand tone.
Optional Logging
If you want to track processed messages, connect a Notion database or another CRM.
How It Works
Webhook catches new Facebook comments.
AI Agent analyzes the comment and categorizes it (question, compliment, complaint, unclear, spam).
Replying:
For questions/requests → public reply + private message with full details.
For compliments → short thank-you reply.
For complaints → apology reply + private message for clarification.
For unclear comments → ask politely if they need help.
For spam/offensive → ignored (no reply).
Replies and messages are sent instantly via the Facebook Graph API.
Customization Ideas
Change the AI prompt to match your brand voice.
Add forwarding to Slack/Email if a human should review certain replies.
Log conversations in Notion, Google Sheets, or a CRM for reporting.
Expand to Instagram or WhatsApp with small adjustments.
