Auto-Generate Platform-Optimized Social Media Posts from WordPress with Claude & Postiz

This workflow automates the process of **generating and scheduling social media posts using content from a WordPress blog**. It leverages advanced AI (OpenAI & Anthropic Claude), Google Sheets, and the [Postiz](https://postiz.com/?ref=n3witalia) platform to create and publish platform-specific posts across **LinkedIn, Facebook, Instagram, and Twitter (X)**. This system streamlines cross-platform social media publishing, ensuring consistent branding and AI-optimized content. --- ### **Key Features** 1. **Content Source: WordPress** Automatically fetches the content of a WordPress post by its **Post ID**. 2. **Content Transformation via AI** Uses Anthropic Claude and OpenAI to generate unique, optimized captions for each platform: - **LinkedIn**: professional and insight-driven - **Instagram**: creative with emojis and storytelling - **Facebook**: community-oriented and friendly - **Twitter (X)**: concise, hashtag-optimized 3. **Visual Generation (Optional)** Uses OpenAI's DALL·E (via OpenRouter) to generate **custom images** based on the AI-generated Instagram and Facebook/LinkedIn captions. 4. **Post Management with Google Sheets** Uses a Google Sheet as the control panel: - Simply input the WordPress **Post ID** - Marks each post as “done” by updating corresponding columns (TWITTER, FACEBOOK, INSTAGRAM, LINKEDIN) 5. **Publishing via Postiz** Uses the **Postiz API** to schedule or immediately publish posts to your connected social accounts. - Handles image uploads and scheduling time for each platform. --- ### **Benefits** - **Intelligent automation**: Saves time by removing manual copywriting and platform formatting. - **Platform optimization**: Ensures posts are tailored to each platform's audience and algorithm. - **No-code friendly**: Simple setup via Google Sheets + Postiz + WordPress. - **Repeatable & Scalable**: Ideal for agencies or content creators managing multiple posts per week. - **+20 Social Media Platforms**: Easy to start with social integrations. --- ### **How It Works** 1. **Input & Data Fetching**: - The workflow starts with a manual trigger (e.g., test workflow) or scheduled execution. - It retrieves a WordPress post ID from a Google Sheets document, then fetches the full post content (title and body) via the WordPress API. 2. **AI-Powered Content Generation**: - The Social Media Manager node (powered by Claude Opus 4.1) analyzes the post and generates **platform-optimized captions** for: - **Twitter/X**: Concise, hashtag-rich text (≈150 chars). - **Facebook/LinkedIn**: Professional yet engaging copy with CTAs. - **Instagram**: Visual-focused captions with emojis and hashtags. - AI-generated images are created for Instagram (square) and Facebook/LinkedIn (landscape) using OpenAI's image model. 3. **Publishing Automation**: - Captions and images are uploaded to **Postiz**, a social media scheduler. - Postiz publishes the content to connected platforms (Twitter, Facebook, LinkedIn, Instagram) at the specified time. - Google Sheets is updated with status markers (e.g., x in columns like `TWITTER`, `FACEBOOK`) to track published posts. --- ### **Set Up Steps** 1. **Prerequisites**: - **Postiz Account**: Sign up for [Postiz](https://postiz.com/?ref=n3witalia) (free trial available). - **API Keys**: Configure Postiz API credentials in the Postiz and Upload Image nodes. - **Social Channels**: Link your social accounts in Postiz's dashboard and note their `integrationId` values (replace XXX in Postiz nodes). 2. **Google Sheets Setup**: - Clone the [template Sheet](https://docs.google.com/spreadsheets/d/1suPQNdgoAzrklleN4ok2mZnsq0GK1dt59oIHv8JWX5U/edit) and add WordPress post IDs to the POST ID column. 3. **Configure Nodes**: - **WordPress**: Add credentials for your WordPress site in the Get Post node. - **AI Models**: Ensure API keys for Claude (Anthropic) and OpenAI (for images) are valid. - **Postiz Nodes**: Replace placeholder `integrationId` values with your actual Postiz channel IDs. 4. **Test & Deploy**: - Trigger the workflow manually to verify captions, images, and Postiz scheduling. - Activate the workflow for automation (e.g., run daily to publish new WordPress posts). **Note**: This workflow requires **self-hosted n8n** due to community nodes (Postiz, LangChain). --- ### **Need help customizing?** [Contact me](mailto:info@n3w.it) for consulting and support or add me on [Linkedin](https://www.linkedin.com/in/davideboizza/).
