It creates posts in two languages, links them as translations through a custom WPML endpoint, generates a featured image, uploads it to WordPress, and assigns the image to both language versions.\n\n### Setup steps\n\n- Configure OpenAI credentials for the article-generation chain and featured-image node.\n- Replace all `https://YOUR_URL` placeholders with the target WordPress site URL.\n- Configure WordPress REST API authentication for the post, media upload, and featured image update HTTP Request nodes.\n- Ensure WPML is installed and that the custom `/wp-json/custom/v1/link...` endpoint exists and can link translated posts.\n- Adjust the prompt in the Set context node to define the article topic, languages, structure, and output fields expected by the structured parser.\n\n### Customization\n\nModify the Set context prompt and structured output schema to change article format, target languages, tone, categories, tags, or image prompt behavior."
