How to Publish Blog Posts to Medium, Dev.to, and Ghost with n8n: A Complete Automation Guide

Publishing blog posts consistently across multiple platforms can be a tedious and time-consuming task for marketing teams, especially in startups and fast-moving companies. 🚀 Automating this process not only reduces manual effort but also ensures timely, standardized publication across channels like Medium, Dev.to, and Ghost.

In this comprehensive guide, tailored to startup CTOs, automation engineers, and operations specialists, you’ll learn how to build reliable automation workflows using n8n—a powerful, open-source automation tool. From connecting triggers such as Google Sheets or Gmail to posting blogs on three popular platforms, this article covers practical, step-by-step instructions with examples, error handling, scalability tips, and security considerations. Read on to streamline your content distribution effortlessly and free your marketing team to focus on strategy and growth.

Understanding the Automation Challenge for Publishing Blogs

Marketing departments often struggle with:

• Managing multiple publishing platforms
• Manual data entry and formatting errors
• Lack of centralized content control
• Delays and missed publication deadlines

Automation workflows integrate various services like Google Sheets (content database), Gmail (content approval emails), Slack (notifications), and publishing platforms (Medium, Dev.to, Ghost) — eliminating tedious repetition.

n8n, compared to Zapier and Make, offers flexibility and is self-hostable, making it ideal for scaling startups concerned with data security and customization.

How the Publishing Automation Workflow Works (End-to-End)

Here’s the typical flow we will implement:

1. Trigger: New blog post metadata added to Google Sheets
2. Content gathering: Pull the article content from a cloud source or email
3. Transformation: Format the content payload, enrich metadata
4. Publish actions: Post the content to Medium, Dev.to, and Ghost using their APIs
5. Notifications: Post success/failure alerts to Slack
6. Logging: Record publishing status back in Google Sheets

Tools and Services Integrated

• Google Sheets: Act as the single source of truth for blog metadata and statuses
• Gmail: Receive or send approval emails to trigger content readiness
• Slack: Real-time notifications for the team upon publishing
• Medium API: For posting Medium blogs
• Dev.to API: For posting articles on Dev.to
• Ghost CMS API: To update/manage posts on your Ghost blog

Setting Up the n8n Workflow: Step-by-Step Breakdown

1. Trigger Node: Google Sheets – Detect New Blog Posts

Use the Google Sheets Trigger node to watch the sheet tracking blog posts.

• Sheet name: Blog Posts
• Trigger type: Poll for new rows every 5 minutes (polling is more reliable here)
• Key fields: Title, Author, Content Link, Status (e.g., ‘Draft’, ‘Ready to Publish’)

Set the node to trigger only if Status == 'Ready to Publish' to filter relevant rows.

2. Retrieve Blog Content

Depending on your content storage, you can fetch blog content via:

• HTTP Request Node: Pull content from a URL (e.g., Google Docs published endpoint or markdown in cloud storage)
• Gmail Node: If content approval arrives as email, use Gmail trigger and extract email body

3. Transform Content and Metadata

Use Function Node to clean, format content, and prepare payloads for each platform considering their API requirements:

• Convert markdown where necessary
• Escape special characters
• Populate fields like tags, canonical URLs

Example function snippet to prepare Medium API request body:

{
  "title": items[0].json.title,
  "contentFormat": "markdown",
  "content": items[0].json.content,
  "tags": items[0].json.tags.split(","),
  "publishStatus": "public"
}

4. Medium Publication Node

Use HTTP Request Node to call the Medium API POST /v1/users/{{userId}}/posts.

• Headers: Authorization: Bearer {{your_medium_token}}
• Body (JSON): as prepared from Function Node

Handle rate limits by including retry settings with exponential backoff.

5. Dev.to Publication Node

Similarly, publish to Dev.to with their API endpoint POST /articles.

• Headers: API-Key from your Dev.to account
• Body: title, body_markdown, tags, published field set to true

6. Ghost CMS Publication Node

Publish a post using Ghost Content API or Admin API:

• Auth: Use Admin API key in headers
• Payload: title, html or markdown content, status (published)

7. Slack Notification Node 📢

Post success or failure notifications via Slack to the marketing channel:

• Message includes blog title, platforms published, and status
• Use IF nodes to route success or error messages

8. Update Google Sheets Status

Use Google Sheets Node to update the Status column as Published or log errors.

Error Handling and Robustness

In automation, errors are inevitable. Here are key tips:

• Retries & Backoff: Configure retry on rate-limit or transient errors with exponential delay
• Idempotency: Ensure posting nodes do not duplicate posts by checking if post URL/ID exists before posting
• Logging: Maintain a log file or Google Sheet tab to record process outcomes and error messages
• Alerting: Send alerts to Slack or email when workflow fails repeatedly

Performance and Scaling Strategies

When workflow volume increases:

• Polling vs Webhooks: Use webhooks where APIs support them for immediate trigger instead of polling
• Concurrency: Set concurrent executions thoughtfully to avoid exceeding API rate limits
• Queueing: Integrate queue nodes or storage (Redis, DB) if bursts of posts require throttling
• Modularization: Split workflow into subflows for each platform to isolate failures
• Versioning: Use n8n’s workflow version control for safe deployment of updates

Security and Compliance Considerations

Secure your automation workflow to protect sensitive data:

• API Keys and Tokens: Store credentials securely in n8n’s credential manager, using scoped API keys with least privilege
• PII Handling: Avoid including user PII in logs or messages unless encrypted
• Access Control: Restrict n8n access and audit usage
• SSL/TLS: Ensure all HTTP requests use HTTPS endpoints

Testing and Monitoring Tips

• Use sandbox/test accounts in Medium, Dev.to, and Ghost for initial development
• Run test flows with sample data and verify outputs
• Leverage n8n’s execution history to debug steps
• Set up health checks and alerts on workflow failures
