Publish Facebook Reels from Video URL (n8n Webhook + Graph API)

Publish Facebook Reels automatically from a public video URL

This n8n workflow exposes a webhook that lets you submit a public video URL and caption, then uses the Facebook Graph API to upload the video as a Facebook Reel—returning the new video_id and a direct Reel link.

What this workflow does

• Receives a POST webhook request with: video_url, caption, optional video_state, and optional scheduled_publish_time.
• Starts a Facebook Reels upload session for the target Facebook Page using the Facebook Graph API (three-phase upload).
• Instructs Facebook to pull the video from your URL (no manual file upload to n8n required).
• Waits briefly for processing to complete after the initial upload steps.
• Finishes the upload by applying the caption and creating the Reel as a draft, scheduled post, or published post (based on video_state).
• Responds with results: the created Reel’s video_id and a link in the format https://www.facebook.com/reel/<video_id>.

Use cases

• Automatically publish marketing Reels from a CMS or media host by sending a public video_url.
• Schedule Reels for a specific time using video_state: "SCHEDULED" and scheduled_publish_time.
• Generate draft Reels for approval workflows before publishing.
• Turn internal automation into a simple API: your app sends JSON to the n8n webhook, and Facebook handles the Reel creation.

Technical details

• n8n nodes/workflow components: webhook, set, code, wait, http request, sticky note.
• Facebook integration: Facebook Page access token via HTTP header Authorization: Bearer <PAGE_ACCESS_TOKEN>.
• Configuration: set YOUR_FACEBOOK_PAGE_ID and ensure your Meta app has the permissions needed to publish Reels.
