Automating AI-Generated Ideas & Post to Blog/Social with n8n – Part 3

Part 3 – Automating AI Posts to Blog and Social Media

This part automates posting AI-generated content to blogs and social media platforms. The workflow includes:

1. Fetching content from Supabase.
2. Looping through multiple content entries (remove if you post one content).
3. Generating relevant images using an AI image generator (Fal.ai).
4. Publishing to a blog (WordPress).
5. Posting to multiple social media platforms (Facebook pages, X, LinkedIn, etc.).

Step-by-Step Implementation

1. Retrieve Content from Supabase

• Use Edit Fields and Split Out node if you process multiple type of contents.
• Add a Loop Over Items node to process each content entry individually for multiple contents.
• Use the Postgres (Select) node to fetch AI-generated content from Supabase.
• Apply filters to retrieve only unpublished or new content.

2. Generate Relevant Images

• Use the Basic LLM Chain to generate an image prompt based on the content.
• Add a HTTP Request node (Fal.ai) to create relevant images.
• Implement a Wait node to check the image generation status (optional).
• Retrieve the generated image URL and download the image to your Google Drive folders (remember to enable edit permission).

4. Post to Blog (WordPress)

• Use a WordPress (Create a Post) node to post content, create slug and select your desired options.
• To upload featured image, use HTTP Request nodes to download from Google Drive folder and upload to WordPress.

5. Post to Facebook Pages

• Use Google Drive node to download image.
• Use the Facebook Graph API to post content and upload the image from previous node.
• Optionally, add automated comments for engagement.
• Remove the image since the content has been posted successfully on Blog and Social Platforms.

6. Logging

• Add Telegram (Create a text message) node to catch log/failures in any stage (e.g., image generation, blog posting, social media posting).
