This proposal outlines a system for automating posts to Facebook Groups using a GitHub-verified workflow. This approach ensures code integrity and secure execution using GitHub Actions. System Architecture: GitHub to Facebook Auto-Poster
n8n is a workflow automation tool that has a native Facebook Graph API node. Self-host it on a VPS or locally.
⚠️ Important: Facebook strictly forbids unauthorized automation. Many “auto-poster” tools get accounts banned. However, Facebook provides an official Graph API with limited group posting capabilities for verified apps.
Solution: Your Long-Lived token expired (usually after 60 days). Verified scripts usually have a "refresh token" feature—configure it.
If you cannot get API approval, community-developed scripts on GitHub use browser simulation. These carry a higher risk of being flagged as "bot behavior" by Facebook.
When searching GitHub for facebook-auto-post, use this checklist to ensure the tool is safe:
GitHub Actions can be configured to trigger these posts automatically (e.g., when you push code or on a schedule): Create a Facebook App : You must register a new app via Meta for Developers Verify Permissions : To post to groups, your app needs the publish_to_groups permission. For production use, Meta requires App Review
