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",

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 '{

      {"value": "backend-tag-id", "label": "Backend"}
    ]
  }' \
  -i "hashnode-id,devto-id"
