Publish to Medium from OpenClaw

OpenClaw can publish and schedule Medium articles through the Postiz skill. You send OpenClaw the article or a link to it, and it calls the Postiz CLI to set the title and subtitle, choose a publication, add up to four tags, and attach a canonical URL pointing back to your original post.

How Postiz Becomes an OpenClaw Skill

When you install Postiz Agent globally, OpenClaw automatically discovers it by reading the bundled SKILL.md file. This file tells OpenClaw what commands are available, what environment variables are needed, and how to compose Medium articles with the right settings.

✓Install from ClawHub with one command: openclaw skills install @nevo-david/postiz
✓OpenClaw reads the SKILL.md and learns all Postiz commands
✓Run openclaw skills check to confirm the postiz binary and credentials are in place
✓Skills are loaded on-demand, keeping the agent context clean
✓Works with any LLM backend: Claude, GPT, Gemini, Llama, and more

Install from ClawHub

# Install the Postiz skill from ClawHub
openclaw skills install @nevo-david/postiz

# Or with the skills CLI
npx skills add gitroomhq/postiz-agent

# Sign in with OAuth2 (or set POSTIZ_API_KEY)

Scheduled & Proactive

openclaw automations for recurring content

OpenClaw automations run on cron expressions in an isolated session and can announce results to a chat channel. Create one that drafts and schedules your Medium content through Postiz, so nothing waits on a manual trigger.

openclaw automations (cron)

openclaw automations create "0 9 * * 1-5" \
  "Check ~/content/blog for a new Markdown article, publish it to Medium with a canonical URL to the original and up to four tags, and schedule it for 9am." \
  --name "Medium daily post" \
  --session isolated \
  --announce --channel telegram \
  --to "<your chat id>"

# openclaw cron is an alias for the same command

✓Message from WhatsApp to publish a Medium article — no terminal needed
✓Cron jobs for hands-free weekly publishing schedules
✓Structured JSON output lets OpenClaw verify each step succeeded
✓Canonical URLs applied automatically when cross-posting from your blog
✓Cross-post to Medium + other platforms in a single conversation

Also Works with Claude Code

Postiz works with any AI agent that can run commands or call MCP tools — you ask, the agent does the work. That includes Anthropic's Claude Code, which has its own guide for posting to Medium from Claude Code.

Claude Code

by Anthropic

Claude reads the Postiz skill so it knows what it can do, then autonomously discovers your Medium integration, formats your article, applies tags and publication settings, and publishes the post.

Claude Code

> Publish my API design article to Medium
  under the engineering publication with
  a canonical URL back to my blog

Claude: Done! Scheduled on Medium for
  tomorrow at 9:00 AM.

Medium + Other Platforms

Publish the same article to Medium and other platforms in a single request. Each platform gets its own settings.

Example

> Post "Excited to announce our new feature!" to
  Medium and LinkedIn tomorrow at 9am, then schedule
  a daily tip on Medium every weekday at 10am

OpenClaw: Done! Scheduled:
  - Medium + LinkedIn: tomorrow 9:00 AM
  - Daily tips on Medium: Mon-Fri 10:00 AM

What can you ask OpenClaw to do on Medium?

These are real messages you can send OpenClaw from WhatsApp, Telegram, Slack, or Discord. OpenClaw maps each one to the right Postiz command and Medium settings.

Cross-post with canonical

Send to OpenClaw

> Publish this article to Medium tomorrow at 9am, subtitle "What we learned shipping agents", canonical to the original URL, tags: ai, open source, automation.

Publication

Send to OpenClaw

> Post this piece to our company publication on Medium instead of my profile.

Repurpose

Send to OpenClaw

> Turn my LinkedIn post from Monday into a 600-word Medium article and schedule it for Friday.

Medium rules OpenClaw has to follow

Postiz enforces these Medium constraints when OpenClaw creates a post. Knowing them up front avoids a failed request.

✓Title and subtitle are both required and need at least two characters each. Give OpenClaw a subtitle or it will draft one.
✓Postiz accepts up to four tags per Medium article. Pick the ones that match your niche rather than broad terms.
✓Set canonical when cross-posting from your own blog so search engines credit the original.
✓Publications need a publication ID. Ask OpenClaw to list your Medium publications through Postiz before posting to one.

OpenClaw and Medium: frequently asked questions

How do I publish to Medium from OpenClaw?

Install the Postiz skill in OpenClaw, run postiz auth:login, and connect your Medium account in Postiz. Then send OpenClaw the article with a title, subtitle, tags, and time. OpenClaw runs postiz posts:create with the Medium settings and confirms the scheduled article.

Can OpenClaw set a canonical URL on Medium?

Yes. Medium has a canonical setting in Postiz. Tell OpenClaw the original URL and it passes it along, so Medium marks your blog as the source. That lets you cross-post for reach without competing with your own site in search.

Can OpenClaw publish to a Medium publication?

Yes. Postiz exposes your publications, and OpenClaw can pass a publication ID in the publication setting. Ask "which Medium publications can I post to?" and OpenClaw lists them, then names the one you choose when it schedules the article. Without a publication, it posts to your profile.

Does OpenClaw need a Medium integration token?

No. Postiz holds the Medium connection, and OpenClaw only runs the Postiz CLI. You authenticate OpenClaw with postiz auth:login or a Postiz API key, and there is no Medium token stored in OpenClaw's configuration. Revoke access from Postiz at any time and OpenClaw loses it too.

Can OpenClaw cross-post my blog to Medium automatically?

Yes. Create an OpenClaw automation with a cron expression and a prompt that checks your blog folder or feed, publishes new articles to Medium with a canonical URL, and schedules them. Ask it to create drafts if you want to review before publishing.
