Hashnode-Specific Features

📖

Blog Publishing

Publish long-form blog posts with full Markdown support. Code blocks, embeds, and rich formatting work out of the box.

📚

Publication Support

Publish posts under your Hashnode publication. Every post requires a publication ID to target the right blog.

🖼

Cover Images

Upload and attach cover images to make your posts stand out. Eye-catching visuals drive more clicks from the Hashnode feed.

🔗

Canonical URLs

Set canonical URLs for SEO when cross-posting from your original blog. Avoid duplicate content penalties across platforms.

🏷

Required Tagging

Hashnode requires at least one tag per post. Tags use tag IDs for precise categorization and improved discoverability.

📅

Scheduled Publishing

Schedule blog posts for future publication with precise timestamps. Build a consistent publishing cadence effortlessly.

How It Works

Find Your Hashnode Integration

List your connected accounts and grab your Hashnode integration ID. You can also fetch available settings to see what options are supported.

Discovery

# List all integrations
postiz integrations:list

# Filter for Hashnode
postiz integrations:list | jq \
  '.[] | select(.identifier=="hashnode")'

# Get Hashnode settings schema
postiz integrations:settings <hashnode-id>

Prepare Your Content

Write your blog post in Markdown. Hashnode supports rich formatting including headers, code blocks with syntax highlighting, images, and embedded content. Optionally upload a cover image.

Upload

# Upload a cover image (optional)
RESULT=$(postiz upload cover.png)
IMAGE_PATH=$(echo "$RESULT" | jq -r '.path')
IMAGE_ID=$(echo "$RESULT" | jq -r '.id')

echo "Cover: $IMAGE_PATH"
# https://uploads.postiz.com/cover.png

Publish Your Post

Create a post with your content, title, publication, tags, and optional cover image and canonical URL. Remember: publication and at least one tag are required.

Publish

postiz posts:create \
  -c "Article body..." \
  -s "2025-03-01T09:00:00Z" \
  --settings '{
    "title": "Getting Started with Bun",
    "subtitle": "A fast JavaScript runtime",

What is OpenClaw?

OpenClaw is the open-source personal AI agent with 145k+ GitHub stars. It runs locally on your machine, connects through apps you already use, and takes real actions on your behalf.

💬

Works Where You Are

Message OpenClaw from WhatsApp, Telegram, Slack, Discord, Signal, iMessage, or 10+ other platforms. No new app to learn.

🧩

Skill-Based Architecture

OpenClaw extends its abilities through Skills — lightweight plugins defined in Markdown files. Postiz is available as a skill on ClawHub.

⏰

Proactive Automation

Schedule recurring tasks with cron jobs. OpenClaw can publish your Hashnode posts on a schedule without you having to ask each time.

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 Hashnode posts with the right settings.

✓Install from ClawHub with one command: clawhub install nevo-david/postiz
✓OpenClaw reads the SKILL.md and learns all Postiz commands
✓Eligibility is checked automatically — POSTIZ_API_KEY must be set
✓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
clawhub install nevo-david/postiz

# Or install the CLI globally
npm install -g postiz

# Set your API key
export POSTIZ_API_KEY=your_api_key

# Verify OpenClaw sees it
openclaw skills list --eligible

# Output:
# - postiz: Social media automation
#   CLI for scheduling posts
#   across 30+ platforms

Hashnode Publishing with OpenClaw

Message OpenClaw from any platform — it reads the Postiz skill, discovers your Hashnode integration, and handles the entire publishing workflow autonomously.

🦀

From Any Chat App

WhatsApp, Telegram, Slack, Discord...

Send a message to OpenClaw from your favorite chat app. It runs as a persistent daemon on your machine, so it picks up your message, discovers your Hashnode blog via Postiz, formats the post, and publishes it — all while you go about your day.

WhatsApp / Telegram

You: Publish my Bun runtime article
  to Hashnode with a cover image,
  tag it with JavaScript and Bun

OpenClaw: Got it! Here's what I'll do:
  1. Upload cover image to Postiz
  2. Read your draft from ~/drafts/bun.md
  3. Publish to your Hashnode publication

  Done! Your Hashnode post is live.
  Post ID: abc-123

🦀

Scheduled & Proactive

Cron jobs for recurring content

OpenClaw supports cron-based heartbeat tasks. Set up a recurring job that checks a folder for new Markdown drafts and publishes them to Hashnode automatically — no manual trigger needed.

openclaw.json (heartbeat)

{
  "heartbeat": [
    {
      "cron": "0 10 * * 1,4",
      "prompt": "Check ~/blog/pending for
  new .md files. For each one,
  extract the title from front matter,
  upload any cover image, publish to
  Hashnode with my publication ID
  and appropriate tags. Move posted
  files to ~/blog/published."
    }
  ]
}

Why OpenClaw + Postiz for Hashnode

OpenClaw's skill system makes Postiz a natural fit. The agent reads the SKILL.md to understand every available command, then autonomously chains them together for Hashnode workflows.

✓Message from WhatsApp to publish a Hashnode post — no terminal needed
✓Cron jobs for hands-free weekly publishing schedules
✓Structured JSON output lets OpenClaw verify each step succeeded
✓Publication ID and tags resolved automatically from your settings
✓Cross-post to Hashnode + other platforms in a single conversation
✓Model-agnostic — works with Claude, GPT, Gemini, or open-source LLMs

Also Works with Claude Code

Postiz Agent works as a CLI tool with any AI agent that can execute shell commands — including Anthropic's Claude Code.

Claude Code

by Anthropic

Claude reads the SKILL.md file to learn all available Postiz commands, then autonomously discovers your Hashnode integration, uploads your cover image, resolves publication and tag IDs, and publishes the post.

Claude Code

> Publish my Node.js streams guide to
  Hashnode with a cover image and tags

Claude will automatically run:
  postiz integrations:list
  postiz upload ./streams-cover.png
  postiz posts:create \
    -c "$(cat streams-guide.md)" \
    -s "2025-03-02T09:00:00Z" \
    --settings '{"title":
      "Complete Guide to Node.js Streams",
      "publication":"pub-id",
      "main_image":{"id":"...",
        "path":"uploaded-url"},
      "tags":[{"value":"nodejs-id",
        "label":"Node.js"},...]}' \
    -i "hashnode-id"

Hashnode + Other Platforms

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

Terminal

# Cross-post an article to Hashnode and Dev.to
postiz posts:create \
  -c "$(cat article.md)" \
  -s "2025-03-01T09:00:00Z" \
  --settings '{
    "title": "Understanding WebSockets",
    "publication": "my-pub-id",
    "canonical": "https://myblog.dev/websockets",
    "tags": [
      {"value": "websocket-tag-id", "label": "WebSockets"},
      {"value": "backend-tag-id", "label": "Backend"}
    ]
  }' \
  -i "hashnode-id,devto-id"

# Batch schedule a week of Hashnode posts
for day in 1 2 3 4 5; do
  postiz posts:create \
    -c "$(cat posts/day${day}.md)" \
    -s "2025-03-0${day}T10:00:00Z" \
    --settings '{"title":"Day '"$day"' Deep Dive","publication":"my-pub-id","tags":[{"value":"series-tag-id","label":"Series"}]}' \
