Automate Instagram & Facebook Posting with Meta Graph API

Automate Instagram & Facebook Posting with the Meta Graph API

This n8n workflow template automates publishing content to Instagram Business and Facebook Pages using the Meta Graph API, including secure handling of short-lived and long-lived access tokens for reliable, ongoing social media automation.

What this workflow does

• Publishes to Instagram by using the Meta Graph API endpoints /media and /media_publish.
• Posts to Facebook Pages via the Meta Graph API /photos endpoint.
• Supports both short-lived and long-lived tokens so you can start quickly and then move to a more stable setup.
• Enables long-lived token automation using Meta Business System User credentials for dependable scheduled posting.
• Handles token refresh logic by using staticData in n8n, helping reduce interruptions as tokens expire.
• Includes inline sticky note instructions to guide authentication and explain how to wire the requests correctly.

Use cases

• Schedule and publish branded social content without manual logins to Instagram or Facebook.
• Automate marketing workflows where content is prepared in a system (e.g., CRM) and then synced to Meta channels.
• Empower internal teams or clients to post with fewer steps by reusing the same n8n automation setup.
