How n8n saved our Advocacy impact on Social Media!

In a previous article, we explained how to host n8n on Upsun.
Since then, we’ve been using n8n to automate our internal workflows — and one pain point in particular has been solved: promoting our DevCenter technical blogposts!

In the Advocacy team, our mission is to publish high-quality, relevant technical blogposts across a variety of topics — ideally with strong engagement.
But until recently, promotion on social media was a manual process, handled by our wonderful and brilliant teammate Community Manager. 🧠💪

And as with any manual process, miscommunication sometimes occurred:

• Sometimes the Advocacy team forgot to ping our Community Manager with a summary and link.
• Sometimes our Community Manager was too busy and missed the momentum for promotion.

This is now history! 🚀

We’ve built an n8n workflow that automatically sends a Slack message to our marketing team whenever a new blogpost is published.
It extracts key metadata (title, URL, image), uses OpenAI to generate a tweet, and notifies our #marketing Slack channel — complete with a pre-written tweet.

💡 If you’re reading this article because of a tweet — then it worked!

Our old workflow (RIP)

Before this automation, our flow looked like this:

1. Write the article on a new Git branch.
2. Open a Pull Request on the DevCenter GitHub repo.
3. ask teammates to review the online version of the blogpost (or the series) via the Upsun preview environment, which is automatically linked in the Pull Request as a comment.
4. Once merged, manually ping the marketing team with the article and a short summary.
5. The marketing team would write a tweet and schedule it for social media.

Our new workflow 🎉

Here’s how it works now:

1. Write the article and open a PR, as usual.
2. Once merged, n8n detects the new blogpost(s).
3. n8n extracts the title(s), author(s), and image(s).
4. It uses OpenAI to generate a tweet.
5. It automatically pings the #marketing Slack channel with everything the team needs.

Why this automation matters

• ⏱️ Time saved for both teams
  Marketing no longer needs to read every blogpost — they receive a tweet-ready summary instantly.

• ⚡ Increased reactivity
  Blogposts are promoted as soon as they’re live, improving reach and engagement.

• 🤝 Better collaboration
  Automation ensures that nothing falls through the cracks, and that both teams stay aligned.

• 📢 Consistent messaging
  OpenAI-generated summaries keep tone and clarity consistent across posts.

• 📈 Scalable promotion
  As our content production scales, we keep a strong social presence without increasing manual effort.

Behind the scenes: How it works

1. GitHub Webhook Trigger
   The workflow listens for push events on the DevCenter repo.

2. Metadata Extraction
   It extracts new .md files, ignores edits to old posts, and parses frontmatter (title, authors, image).

3. Tweet Generation
   OpenAI creates a short, clear tweet summarizing the article.

4. Slack Notification
   It posts to #marketing with:

   • Article title
   • GitHub authors (linked)
   • Article URL
   • Tweet suggestion
   • Thumbnail image

Final Result: What It Looks Like

Here’s an example of the Slack message sent by the workflow:

Want to build it yourself?

You can grab the exported n8n workflow here.
Once imported into your n8n instance, configure the following:

• 🔑 Credentials: Add OpenAI, GitHub, and Slack credentials from your n8n account.
• 🔗 GitHub Repo: Update the repo URL in the Github Repo DevCenter trigger block.
• 👤 Author Extraction Logic: On our DevCenter, authors are listed with GitHub usernames. Update this logic if yours differs in the Extract Title+authors+image block.

Conclusion

This automation boosted our Advocacy impact by bridging content creation and promotion — instantly and with minimal effort. It keeps both the Advocacy and Marketing teams in sync, and speeds up social sharing of our technical content.

If you’re managing internal content workflows and want to scale your reach without scaling your workload: Try n8n. Add OpenAI. Automate the boring parts.

Happy automating! 🚀
