Quick overview
This workflow generates an SEO-friendly blog post in Italian and English with OpenAI, publishes both versions to WordPress via the REST API, links them as WPML translations through a custom endpoint, generates a featured image, uploads it to the WordPress media library, and assigns it to both posts.
How it works
- Runs manually when you click “Test workflow” in n8n.
- Sets a topic prompt used to generate the article.
- Uses OpenAI to produce structured output containing an Italian and English title and HTML article content.
- Creates the Italian WordPress post and then creates the English WordPress post via the WordPress REST API.
- Calls a custom WordPress REST endpoint to link the two posts as WPML translations.
- Generates a realistic cover image with OpenAI, uploads it to the WordPress media library, and sets it as the featured image for both posts.
Setup
- Add OpenAI credentials for text generation (chat model) and image generation (gpt-image-1).
- Add WordPress API credentials and replace all instances of
YOUR_URL with your WordPress site URL.
- Install and configure WPML with the
it and en language codes (or update the workflow to match your site’s languages).
- Add the provided PHP code to your theme’s
functions.php (or a custom plugin) to expose /wp-json/custom/v1/link-translation, and verify it is reachable.
- Replace
YOUR_PROMPT with your desired topic prompt before running the workflow.
