🚀 Automating Facebook Page Posting Using the Meta Graph API (2025 Full Guide)

This guide explains how to automate posting to a Facebook Page using the Meta Graph API, including setup, token generation, posting, deleting posts, and best practices. All sensitive values in this guide use safe placeholders.

🔍 Overview

• Platform: Facebook (Meta)
• API: Graph API v22.0
• Goal: Automate posting to your Facebook Page
• Method: System User (long-lived automation account)
• Difficulty: Easy–Moderate
• Best For: Event posting, affiliate posting, alerts, scheduled content, bots

✅ Requirements

Before you start, you must have:

1. Meta Developer App — https://developers.facebook.com
2. Meta Business Manager account — required for System User tokens
3. A Facebook Page you manage
4. A System User added inside Business Manager
5. Permissions granted to the System User:
   • pages_manage_posts
   • pages_read_engagement
   • pages_show_list
   • public_profile

⭐ Step 1 — Create a System User

1. Go to Business Settings → Users → System Users
2. Click Add System User
3. Choose a name → Role = Admin
4. Assign the System User to:
   • your Facebook Page
   • your Facebook App

This System User is what allows automated posting.

⭐ Step 2 — Generate a System User Token

Inside Business Settings → System Users → Select your system user:

1. Click Generate Token
2. Select your App
3. Enable these scopes:
   • pages_manage_posts
   • pages_read_engagement
   • pages_show_list
   • public_profile

You will receive a 60-day renewable System User Token:

🔒 Keep this private — never store in GitHub.

⭐ Step 3 — Get Your Facebook Page ID

Find it in:

Business Settings → Pages → Select Page

Example:

You need this for every API request.

⭐ Step 4 — Fetch Your Page Access Token

Use the System User Token to request a Page Token:

📌 cURL

curl -X GET \
"https://graph.facebook.com/v22.0/123456789012345?fields=access_token&access_token=1234567890abcdefSYSTEMUSERTOKEN1234567890"

Response:

{
  "access_token": "1234567890abcdefPAGEACCESSTOKEN1234567890",
  "id": "123456789012345"
}

Save the page_access_token. This is the token you actually use to post.

⭐ Step 5 — Post to the Facebook Page

📌 cURL Example

curl -X POST "https://graph.facebook.com/v22.0/123456789012345/feed" \
-F "message=🎉 New events are live this week!" \
-F "link=https://yourdomain.com/events" \
-F "access_token=1234567890abcdefPAGEACCESSTOKEN1234567890"

📌 Python Example

import requests

PAGE_ID = "123456789012345"
PAGE_TOKEN = "1234567890abcdefPAGEACCESSTOKEN1234567890"

def post_to_facebook(message, link=None):
    url = f"https://graph.facebook.com/v22.0/{PAGE_ID}/feed"
    payload = {
        "message": message,
        "access_token": PAGE_TOKEN
    }

    if link:
        payload["link"] = link

    res = requests.post(url, data=payload)
    print(res.json())

post_to_facebook(
    message="📣 Don't miss this week's updates!",
    link="https://yourdomain.com/events"
)

This automatically generates a clickable preview card.

⭐ Step 6 — Delete a Facebook Post

Every successful post returns an ID like:

📌 cURL

curl -X DELETE \
"https://graph.facebook.com/v22.0/123456789012345_987654321098765?access_token=1234567890abcdefPAGEACCESSTOKEN1234567890"

📌 Python

import requests

POST_ID = "123456789012345_987654321098765"
PAGE_TOKEN = "1234567890abcdefPAGEACCESSTOKEN1234567890"

url = f"https://graph.facebook.com/v22.0/{POST_ID}"
res = requests.delete(url, params={"access_token": PAGE_TOKEN})
print(res.json())

⭐ Step 7 — Token Expiration & Refreshing

• Tokens last 60 days
• To renew:
  1. Generate a new System User Token
  2. Fetch a new Page Token using the same API call
• Automate renewal every 55 days to be safe

⭐ Step 8 — Security Best Practices

• Store tokens in environment variables (.env files)
• Never commit tokens to GitHub
• Restrict access to servers that run posting scripts
• Use HTTPS links for best preview rendering

⭐ Step 9 — Common Automation Use Cases

• ✔️ Auto-posting events
• ✔️ Affiliate link previews
• ✔️ Scheduled promotions
• ✔️ Auto-sharing blog posts
• ✔️ Marketplace bots
• ✔️ Ticketing websites
• ✔️ Announcement systems

By using a System User + Page Access Token, you get the most stable, long-lived, automation-friendly way to publish content to Facebook.
