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",
