🔧 How to Create an Automated Facebook Posting Workflow with n8n

This guide walks you through setting up a complete workflow in n8n to:

Automatically refresh your Facebook token
Post content to Facebook Groups, Pages, or your Personal Profile
Optionally leave a comment on the post right after publishing

✅ Prerequisites

Before you begin, make sure you have:

An active Facebook App (with permissions for pages_manage_posts, groups_access_member_info, publish_to_groups, etc.)
A valid Facebook Access Token (User or Page token)
n8n installed (either cloud version or self-hosted)
Basic knowledge of how to use HTTP Request Node in n8n

🔄 Step 1: Automatically Refresh Facebook Token

If you're using short-lived tokens, you should refresh them regularly.

🔹 Node: HTTP Request (Token Refresh)

Method: GET

URL:

  https://graph.facebook.com/oauth/access_token?  
  grant_type=fb_exchange_token&  
  client_id=<YOUR_APP_ID>&  
  client_secret=<YOUR_APP_SECRET>&  
  fb_exchange_token=<YOUR_SHORT_LIVED_TOKEN>

Response: Long-lived token
Store token using a Set or Function node for reuse in next steps.

💡 You can also store tokens in n8n credentials, or use a Webhook + UI to manually refresh tokens periodically.

✍️ Step 2: Prepare Post Content

You can use:

Google Sheets
Airtable
Notion
Static JSON / Set Node

Example using Set Node:

{
  "text": "🎉 New post via n8n! Automate your life 🚀",
  "link": "https://yourwebsite.com",
  "image": "https://yourimageurl.com/image.jpg"
}

🚀 Step 3: Post to Facebook Group / Page / Profile

🔹 Node: HTTP Request (POST)

Method: POST
URL Options:
- Group: https://graph.facebook.com/<GROUP_ID>/feed
- Page: https://graph.facebook.com/<PAGE_ID>/feed
- Profile: https://graph.facebook.com/me/feed
Headers:
- Content-Type: application/x-www-form-urlencoded
Body Parameters:
- message: Your content (from Set node)
- access_token: Use your token
- Optional: link, picture

✔️ Use expressions like {{ $json["text"] }} to dynamically insert data.

💬 Step 4 (Optional): Auto-Comment After Posting

After publishing, use the returned id (post ID) from the previous step to comment.

🔹 Node: HTTP Request (POST)

Method: POST

URL:

  https://graph.facebook.com/{{ $json["id"] }}/comments

Body Parameters:
- message: "Thanks for reading! 🚀"
- access_token: Your valid token

📬 Step 5 (Optional): Send Notification or Log

Send a message to Telegram/Slack/Email confirming that the post was published.

Example:

🔹 Node: Telegram

Text: ✅ Post to Facebook Group successful!

🔁 Step 6: Automate with a Schedule or Webhook

Add a Cron node to run it daily/hourly, or use a Webhook trigger to run it manually.

🎁 Bonus Tips

Store tokens and post content in variables or external services.
Add error handling with Error Trigger or IF nodes.
Use Wait node if you want to delay comments after post.
