You just hit publish on a new article — now you have to tell everyone, on every network, one post at a time. This n8n workflow does it for you: it watches your blog’s RSS feed and, for each new post, builds and schedules a social update with the article’s image across all your connected accounts via Posta. It’s the simplest automation to set up and a great first taste of pairing n8n with Posta.
What it does
- Reads your blog RSS feed and picks up new articles.
- Downloads the article image and uploads it to Posta, which auto-scales it per platform (e.g. 9:16 for TikTok) with face-aware cropping.
- Creates one post across one or many accounts and schedules it for the time you choose.
How it works
- RSS Read — point it at your feed (e.g.
https://getposta.app/feed.xml). - Get many social accounts (Posta) — grab the account IDs you want to post to.
- HTTP Request — download the article image as a file.
- Upload media (Posta) — upload it; per-platform scaling starts automatically.
- Merge — combine the media ID with the article text by position.
- Create a post → Schedule a post (Posta) — set caption, accounts, and a publish time.

Don’t build it by hand — import the ready-made workflow (download the JSON or use n8n’s “Import from URL”), connect your Posta account, and you’re live. Swap the manual trigger for a Schedule Trigger to run it on autopilot. Browse all our n8n templates for more.
