Social media automation in n8n with the Hookpost node

What the node can do

Six operations. This is the complete list.

Create Post

Schedule a post, publish it now, or save it as a draft. The channel dropdown lists the channels you have connected in Hookpost. Leave Date empty on a scheduled post and the node asks Hookpost for the next free slot in your posting schedule.

List Posts

Return every post between a start date and an end date.

Delete Post

Delete a post by its id.

List Channels

Return your connected channels with their ids.

Find Free Slot

Return the next free slot in your posting schedule for one channel.

Upload From URL

Pull an image or video from a public URL into your Hookpost media library. The result has a path you can pass to Create Post.

Create Post also takes two optional fields. Image URLs is a comma-separated list of media already in Hookpost, usually the path returned by Upload From URL. Channel Settings (JSON) carries the extra fields some networks need. YouTube, for example, needs a title and a visibility:

{
  "__type": "youtube",
  "title": "My video",
  "type": "private",
  "selfDeclaredMadeForKids": "no"
}

There is no trigger node. To start a workflow when a post goes live, add a webhook in Hookpost under Settings → Webhooks pointing at an n8n Webhook node. Hookpost sends the post as JSON after it publishes, and you can limit a webhook to specific channels.

Example: blog RSS to LinkedIn and X

A three-node workflow that queues every new blog post for LinkedIn and X in your next free slots.

1. RSS Feed Trigger (built into n8n), pointed at your blog's feed.
2. Hookpost → Create Post. Channel: your LinkedIn profile. When: Schedule. Date: empty, so it takes the next free slot. Content:

   New on the blog: {{ $json.title }}
   
   {{ $json.link }}

3. Hookpost → Create Post, connected to the same trigger. Channel: your X account. When: Schedule. Content:

   {{ $json.title }} {{ $json.link }}

Hookpost checks each post against the network's rules before queueing it, so a title that pushes the X post past 280 characters fails at the node with a readable error rather than at publish time. Turn on Continue On Fail and the error is passed downstream as { "error": "..." }, which you can route to Slack or email.

To attach an image, put Upload From URL before Create Post and set Image URLs to {{ $json.path }}.

Channels the node can publish to today

• X (Twitter)
• LinkedIn
• YouTube
• Facebook Pages
• Bluesky
• Discord
• Slack
• Telegram
• WordPress
• Hashnode
• Dev.to
• Lemmy
• Nostr
• Listmonk

Instagram and Threads are built but waiting on Meta app approval, so new accounts cannot connect them yet. Pinterest can be connected but cannot publish yet. Medium stopped issuing new API tokens, so only accounts with an older token can connect.

Coming from the Postiz node?

n8n-nodes-postiz is built for Postiz accounts, and it is on n8n's verified list, so it runs on n8n Cloud. n8n-nodes-hookpost is for Hookpost accounts and, for now, needs self-hosted n8n. Which one you want depends on where your account lives. Hookpost charges one flat price per plan rather than per channel, with rupee billing and UPI Autopay in India. See the Postiz comparison.
