DIY Setup Guide: Automated Social Media Content Publishing Workflow
Want to save time posting across LinkedIn, Facebook, Instagram, X (Twitter), Threads, and YouTube Shorts?
This workflow turns your ideas into ready-to-publish content with images, hashtags, and calls-to-action — all in one place.
Follow these steps to set it up yourself:
🔧 Step 1: Install n8n
- Go to n8n.io and install n8n on your machine, cloud, or Docker.
- Create a free n8n account if you want to use the hosted version.
- Once installed, log in to your n8n editor at
http://localhost:5678(or your cloud workspace).
📂 Step 2: Import the Workflow
- Download the JSON workflow file provided in the members area.
- In your n8n dashboard, click Import → From File.
- Upload the JSON file and you’ll see the workflow canvas with all preconfigured nodes.
⚙️ Step 3: Connect Your Accounts
The workflow publishes to multiple platforms. Update the credentials for each service:
- X (Twitter) → Add
twitterOAuth2Api. - Facebook & Instagram → Add
facebookGraphApi. - LinkedIn → Add
linkedInOAuth2Api. - YouTube Shorts → Connect via your Google account.
- Gmail (optional) → For approval flows and notifications.

👉 In n8n, go to Credentials, create each connection, and link them to the nodes in the workflow.
🖼 Step 4: Enable Image Creation
This workflow integrates Pollinations.ai to generate AI images.
- No extra setup required, but you’ll need a free API key if you want to save images via imgbb.com or Google Drive.
- Update the
IMGBB_API_KEYin your n8n environment variables if you want image hosting.

- Instagram: short, visual, with emojis.
- Facebook: friendly, community-style.
- X (Twitter): short, punchy, max 150 characters.
