Repurpose a Blog Post or Video into Social Media Posts

You wrote a blog post. Or recorded a YouTube video. Or published a newsletter. Now you need to turn that content into posts for LinkedIn, Twitter, Instagram, TikTok, and Threads. Manually rewriting the same content six different ways takes hours.

This is one of the most common automation requests on the n8n forum and Make.com forum. Users build workflows that scrape a URL, extract the text, feed it into ChatGPT, and then wrestle with each platform's API to publish. The scraping step breaks on paywalled sites. The AI step needs careful prompting per platform. The publishing step requires separate OAuth setups for each social network.

Here is a three-step workflow that handles all of it.

The three-step pipeline

1. Ingest: Give Blotato a URL. It extracts the content (article text, YouTube transcript, TikTok transcript, PDF text, or audio transcription).

2. Transform: Blotato's AI rewrites the extracted content for each platform using custom instructions you provide.

3. Publish: Send the transformed content to each platform with one API call per platform.

Step 1: Extract content from a URL

Use the Create Source endpoint. Pass the URL and tell Blotato what type of content it is:

{
  "source": {
    "sourceType": "article",
    "url": "https://example.com/my-blog-post"
  },
  "customInstructions": "Summarize this article in 3 key takeaways. Write in first person."
}

For a YouTube video:

{
  "source": {
    "sourceType": "youtube",
    "url": "https://www.youtube.com/watch?v=VIDEO_ID"
  },
  "customInstructions": "Extract the 5 most actionable tips from this video."
}

Supported source types: article, youtube, tiktok, pdf, audio, twitter, text, and perplexity-query.

The response returns an id. Poll the Get Source endpoint with that ID until the status is completed. The response includes the extracted and transformed text.

Step 2: Publish to each platform

Take the extracted text and pass it to the Publish Post endpoint for each platform. One API call per platform.

LinkedIn example:

{
  "post": {
    "accountId": "your-linkedin-account-id",
    "content": {
      "text": "3 takeaways from my latest blog post:\n\n1. First point...\n2. Second point...\n3. Third point...\n\nRead the full post: https://example.com/my-blog-post",
      "mediaUrls": [],
      "platform": "linkedin"
    },
    "target": {
      "targetType": "linkedin"
    }
  }
}

Twitter example (same content, different platform):

{
  "post": {
    "accountId": "your-twitter-account-id",
    "content": {
      "text": "3 takeaways from my latest blog post (thread):",
      "mediaUrls": [],
      "platform": "twitter",
      "additionalPosts": [
        { "text": "1. First point...", "mediaUrls": [] },
        { "text": "2. Second point...", "mediaUrls": [] },
        { "text": "3. Third point...\n\nFull post: https://example.com/my-blog-post", "mediaUrls": [] }
      ]
    },
    "target": {
      "targetType": "twitter"
    }
  }
}

Step-by-step: n8n workflow

1. Install the Blotato community node in n8n (Settings > Community Nodes > search "Blotato").

2. Add a trigger node. Use a webhook (so you fire it when you publish a new post), a Google Sheets trigger (add URLs to a spreadsheet), or a schedule (check an RSS feed on a timer).

3. Add a Blotato Create Source node. Set the source type to article (or youtube, depending on your content). Pass the URL from the trigger. Add custom instructions describing how you want the content summarized.

4. Add a Blotato Get Source node. Connect it to the Create Source node. Pass the source ID. Enable polling until status is completed.

5. Add one Blotato Publish Post node per platform. Connect them in parallel from the Get Source node.

6. Map the extracted text into each Publish Post node's text field. Adjust the text per platform if needed (shorter for Twitter, longer for LinkedIn).

7. Activate the workflow.

Step-by-step: Make.com scenario

1. Add a trigger module (webhook, Google Sheets, or RSS).

2. Add an HTTP module to call POST https://backend.blotato.com/v2/source-resolutions-v3 with the blotato-api-key header and your source type and URL in the body.

3. Add a second HTTP module to poll GET https://backend.blotato.com/v2/source-resolutions-v3/{id} until status is completed. Use Make's built-in repeater or sleep module for polling.

4. Add a Router module after the source is complete.

5. Add one HTTP module per platform route, each calling POST https://backend.blotato.com/v2/posts with the platform-specific request body.

6. Activate the scenario.

What you feed in vs. what comes out

Input	Source type	Output
Blog post URL	article	Extracted article text, transformed by your custom instructions
YouTube video URL	youtube	Full transcript, transformed by your custom instructions
TikTok video URL	tiktok	Transcript from the video
PDF URL	pdf	Extracted text from the document
Audio file URL	audio	Transcription of the audio
Raw text	text	Your text, transformed by custom instructions
Search query	perplexity-query	AI-researched answer to your query

Scheduling repurposed posts

Instead of publishing immediately, stagger your posts across the week. Add scheduledTime or useNextFreeSlot to each publish request:

{
  "post": { ... },
  "scheduledTime": "2026-04-07T09:00:00+00:00"
}

Or let Blotato pick the next open slot in your content calendar:

{
  "post": { ... },
  "useNextFreeSlot": true
}

See Build a Social Media Scheduler for a full scheduling walkthrough.
