WordPress to LinkedIn, X & Facebook Webhook (n8n Workflow)

Automatically share every new WordPress post to LinkedIn, X (Twitter), and Facebook—using a secure n8n webhook

This n8n workflow listens for a new WordPress post and immediately publishes it to your LinkedIn, X, and Facebook Page. No scheduler to manage—WordPress triggers the workflow once per post via a protected webhook endpoint.

What this workflow does

• Receives a webhook from WordPress with the payload {"post_id": 123} (header authentication keeps the endpoint private).
• Fetches the post details from your site using /wp-json/wp/v2/posts/123?_embed=wp:featuredmedia (published posts are public, so no WordPress credentials are required).
• Extracts post fields in a Code node: it converts the REST response into title, summary, url, and image_url by stripping HTML from the excerpt, decoding entities, and selecting the featured image if available.
• Handles featured images intelligently:
  • If a featured image exists, it publishes with the image on LinkedIn, and uses the page’s Open Graph image for X and Facebook.
  • If no featured image exists, LinkedIn falls back to Publish Link on LinkedIn (link card style).
• Continues even if one network fails: each publish node can proceed independently, so a LinkedIn outage won’t block X or Facebook.

Use cases

• SaaS operators promoting every blog post across social channels without manual copy/paste.
• Automation engineers standardizing a WordPress → social distribution pipeline in n8n.
• Teams using featured images on WordPress to consistently generate richer social previews.
