• An n8n instance (Cloud or self-hosted).
• OpenAI API Key with access to GPT-4 models (e.g., gpt-4-1106-preview, gpt-4-0125-preview) and DALL-E image generation capabilities.
• WordPress site credentials that n8n can use (e.g., Application Password for REST API access).
• The base URL of your WordPress installation.

1. Download the n8n workflow JSON file.
2. Import the workflow into your n8n instance.
3. Configure Credentials:
   • In the 'Create post title and structure', 'Create chapters text', and 'Generate featured image' OpenAI nodes, select or create your OpenAI API credentials.
   • In the 'Post on Wordpress', 'Upload media', and 'Set image ID for the post' nodes, select or create your WordPress credentials.
4. Configure Settings Node:
   • Open the 'Settings' node.
   • Update the wordpress_url variable with the full base URL of your WordPress site (e.g., https://yourblog.com/).
5. Verify WordPress Endpoint URLs:
   • Open the 'Upload media' (HTTP Request) node. Ensure its URL parameter correctly points to your WordPress media endpoint. It should ideally use the wordpress_url variable like this: {{ $('Settings').item.json.wordpress_url }}wp-json/wp/v2/media. Adjust if it's hardcoded to a demo URL.
   • Open the 'Set image ID for the post' (HTTP Request) node. Ensure its URL parameter correctly points to your WordPress posts endpoint. It should ideally use the wordpress_url variable and the dynamic post ID like this: {{ $('Settings').item.json.wordpress_url }}wp-json/wp/v2/posts/{{ $('Post on Wordpress').item.json.id }}. Adjust if necessary.
6. Customize Prompts (Optional):
   • Review the prompts within the 'Create post title and structure' and 'Create chapters text' OpenAI nodes to fine-tune the AI's output style, tone, or specific instructions.
7. Activate Workflow: Save any changes and activate the workflow.
8. Trigger the Agent: Access the URL provided by the 'Form' trigger node (e.g., your-n8n-instance-url/webhook/create-wordpress-post) in your browser. Fill in the keywords, number of chapters, and max word count to generate your first AI-powered WordPress post.
