Step-by-Step Guide

Complete Workflow

1. Setting Up the Ghost Webhook

Ghost Webhooks
Trigger events when something happens in Ghost using webhooks configured through the Ghost Admin user interface. Find out more on Ghost Docs 👉
Ghost - The Professional Publishing Platform

The first step in this automation process is configuring a webhook in the Ghost blog. Ghost provides built-in support for webhooks, allowing you to trigger external workflows whenever a blog post is published.

  • Navigate to your Ghost admin dashboard.
  • Go to Settings > Integrations and create a new custom integration.
  • In the custom integration settings, add a webhook with the event "Post Published".
  • Set the webhook URL to your n8n instance's webhook node endpoint (e.g., https://your-n8n-instance/webhook/blog-post).

This webhook sends data about the newly published post, including every details you need.

2. Verifying Webhook Security

To ensure that the incoming webhook requests are authentic and have not been tampered with, we use cryptographic verification.

In n8n, this is implemented with a Code Node that validates the request signature provided by Ghost.

Here’s how the verification works:

  • Ghost sends a signature in the x-ghost-signature header. This signature is a hash of the webhook payload and a secret key.
  • In n8n, the payload is re-hashed using the same secret key, and the result is compared to the signature from Ghost.
  • If the values match, the request is considered authentic.

Example signature verification code:

const crypto = require('crypto');

function verifyGhostSignature(items) {
    const item = items[0];
    const headers = item.json.headers;
    const signature = headers['x-ghost-signature'];
    
    if (!signature) {
        return { verified: false, error: 'No signature found' };
    }

    const [sigHash, timeStamp] = signature.split(', ');
    const [, hash] = sigHash.split('=');
    const [, ts] = timeStamp.split('=');

    const secret = {YOUR_SECRET};
    const bodyString = JSON.stringify(item.json.body);
    const message = `${bodyString}${ts}`;

    const hmac = crypto.createHmac('sha256', secret);
    hmac.update(message);
    const computedHash = hmac.digest('hex');

    return {
        verified: computedHash === hash,
        debug: {
            secret: secret,
            signature: signature,
            timestamp: ts,
            computedHash: computedHash
        }
    };
}

return verifyGhostSignature(items);

3. Generating Social Media Content

This is where the magic happens—DeepSeek V3 is used to craft optimized content for each social media platform. In n8n, the blog data captured from the webhook is passed to DeepSeek’s API.

DeepSeek API Docs

In n8n, this can be done by a HTTP Request node:

  1. Set the method as POST.
  2. Set the URL as https://api.deepseek.com/chat/completions.
  3. Set Authentication as Generic Credential Type, Header Auth.
  4. Use Authorization as the name of the header and Bearer $token as the value.
  5. Set the request body with proper prompt.

For example, a prompt to generate a tweet might look like:

{
  "messages": [
    {
      "content": "You are a social media specialist. Create ONE tweet that must be under 240 characters total (including spaces and the URL). Summarize the blog post's key message in a conversational tone with 1-2 relevant emojis. Include the URL at the end. Do not use hashtags. No markdown formatting. Note: Count each character carefully - the tweet must fit Twitter's limit even with the full URL included.",
      "role": "system"
    },
    {
      "content": "Title: {{ encodeURIComponent($json.title) }}, Content: {{ encodeURIComponent($json.html) }}, URL: {{ encodeURIComponent($json.url) }}",
      "role": "user"
    }
  ],
  "model": "deepseek-chat",
  "frequency_penalty": 0,
  "max_tokens": 4096,
  "presence_penalty": 0,
  "response_format": {
    "type": "text"
  },
  "stop": null,
  "stream": false,
  "stream_options": null,
  "temperature": 1,
  "top_p": 1,
  "tools": null,
  "tool_choice": "none",
  "logprobs": false,
  "top_logprobs": null
}

Example outputs:

DeepSeek ensures that each platform gets tailored content optimized for engagement.

4. Posting to Social Media

Posting to social media is the most intricate part of this automation workflow. Each platform has its unique API structure and content requirements, making this step the most dynamic. Below is how the workflow handles posting to each platform, leveraging n8n’s integration capabilities and API flexibility.

a. Posting to X (formerly Twitter)

For X, the workflow utilizes the Twitter OAuth2 API integration in n8n to publish tweets. The generated tweet content from DeepSeek V3 is used as the post text.

You can follow n8n's official guidelines on how to make the X node work properly for creating post.

b. Posting to Bluesky

Bluesky’s API offers a unique way to post updates with metadata and images, and the workflow integrates seamlessly using a custom n8n node. This integration utilizes the Bluesky Nodes for n8n, which can be installed and configured easily.

Installing the Bluesky Node

To set up the Bluesky integration in your n8n instance:

  1. Navigate to Settings → Community Nodes.
  2. Click Install and input the node name: @muench-dev/n8n-nodes-bluesky.
  3. Once installed, the node will be available in your workflows.

The node is maintained on GitHub, where you can find documentation and updates.

Bluesky Nodes for n8n. Contribute to muench-dev/n8n-nodes-bluesky development by creating an account on GitHub.
GitHubmuench-dev

Setting Up Authentication

To authenticate with Bluesky's API, you’ll need to generate an App Password:

  1. Log in to your Bluesky account.
  2. Go to Settings → App Passwords (Direct Link).
  3. Create a new app password and note it down, as it will be used in the node’s credentials configuration.

Steps in the Workflow

  1. Set an extra "Get Feature Image for Bluesky" HTTP Request node fetches the blog post’s featured image as the binary data.
  2. The "Post to Bluesky" node uses the custom integration to create a post with:
    • Text: The Bluesky-optimized content generated by DeepSeek V3.
    • Website Card Metadata: Includes:
      • URI: The blog post URL.
      • Title: The blog title.
      • Description: The blog’s excerpt or summary.
      • Binary Property: The featured image fetched earlier.

c. Posting to LinkedIn

LinkedIn requires a more formal approach. The workflow uses the LinkedIn node in n8n to share posts.

For the integration, you can find out the official documentation here:

d. Posting to Mastodon

Mastodon operates on decentralized instances, each with its own unique API. Since n8n does not have a built-in Mastodon integration, we use the official Mastodon API documentation to implement the functionality using HTTP Request nodes. Specifically, the workflow relies on the /media and /statuses endpoints to upload images and publish status updates.

statuses API methods
Publish, interact, and view information about statuses.
Dotcom-Monitor

Steps in the Workflow

  1. Download the Blog’s Featured Image
    • Set up a "Get Feature Image for Mastodon" node fetches the featured image from the blog post's URL (HTTP Request node).
    • This image is prepared for upload to Mastodon.
  2. Upload the Image to Mastodon
    • Set up a "Upload Image" node sends a POST request to the /media endpoint of the Mastodon API. This uploads the image to the Mastodon instance and returns a media_id that can be used in the status update.

e. Workflow Logic for Success and Failures

After posting to all platforms:

  1. The workflow checks the success of each post using conditional logic.
  2. If all platforms successfully receive their posts, the workflow triggers the "Push Succeed Message" node, notifying you of the success.
  3. If any post fails (e.g., due to API issues, invalid tokens, or image upload errors), the workflow triggers the "Push Failed Message" node with details about the issue.

Conditional Logic Node:

  • Checks whether all social media post nodes return a valid ID or URI.
  • Sends success or failure notifications accordingly.

Benefits and Results

Implementing this automated content distribution system yields significant advantages that extend beyond mere convenience. Let's examine the tangible benefits that make this solution particularly valuable for content creators and organizations.

Quantifiable Time Savings

The automation workflow dramatically reduces the time spent on content distribution:

  • Manual posting across platforms typically takes 30-45 minutes per article
  • With automation, the entire process executes in under 2 minutes
