Add AI-Generated Headings & Conclusions to WordPress Posts with GPT-4

This n8n workflow automates the process of enriching WordPress posts by generating AI-powered headings and conclusions using OpenAI's GPT-4, and then updating the posts.

What it does

This workflow streamlines content enhancement for WordPress posts through the following steps:

1. Manual Trigger: The workflow is initiated manually, allowing you to control when to process posts.
2. Edit Fields (Set): This node is intentionally left empty in the provided JSON, suggesting it's a placeholder for defining input data or variables if needed before making API calls.
3. HTTP Request (Placeholder): This node is configured as an HTTP Request, likely intended to fetch WordPress post content or interact with another API. However, its specific configuration (URL, method, headers, body) is not present in the provided JSON, indicating it's a placeholder or incomplete.
4. OpenAI (Placeholder): This node is set up for OpenAI, likely intended to interact with the GPT-4 model to generate headings and conclusions. Similar to the HTTP Request node, its specific configuration (model, prompt, API key) is missing from the JSON, suggesting it's a placeholder.
5. Code (Placeholder): This node is a Code node, typically used for custom JavaScript logic. In its current state in the JSON, it's empty, implying it's a placeholder for any custom processing, data manipulation, or integration logic required after AI generation and before updating WordPress.
6. HTTP Request (Placeholder): Another HTTP Request node, likely intended to update the WordPress post with the newly generated content. Its configuration is also missing from the JSON.
7. Sticky Note: A sticky note is present in the workflow, likely for documentation or comments within the n8n editor.

Prerequisites/Requirements

To fully utilize this workflow once configured, you will need:

• WordPress Account: Access to a WordPress site with API capabilities enabled.
• OpenAI API Key: An API key for OpenAI to access GPT-4 or other models for content generation.
• n8n Instance: A running n8n instance to import and execute the workflow.

Setup/Usage

1. Import the workflow: Import the provided JSON into your n8n instance.
2. Configure Credentials:
   • Set up your OpenAI credentials within n8n.
   • Configure any necessary WordPress API credentials (e.g., Basic Auth, OAuth) if the HTTP Request nodes are intended to interact directly with WordPress.
3. Configure Placeholder Nodes:
   • HTTP Request nodes: Update the two "HTTP Request" nodes with the correct URLs, methods (e.g., GET for fetching posts, POST/PUT for updating posts), headers (e.g., for authentication), and body content to interact with your WordPress API.
   • OpenAI node: Configure the "OpenAI" node with the appropriate model (e.g., gpt-4), and a detailed prompt to generate headings and conclusions based on the WordPress post content.
   • Code node: Implement JavaScript logic in the "Code" node to extract relevant content from the WordPress post, format the prompt for OpenAI, parse the AI-generated response, and structure the data for updating the WordPress post.
   • Edit Fields (Set) node: If you need to define specific input data or variables at the start of the workflow, configure this node accordingly.
4. Test the workflow: Run the workflow manually using the "When clicking ‘Execute workflow’" trigger to ensure all steps are correctly executed and the WordPress posts are updated as expected.
