Generate & upload an audio summary of a WordPress (or Woocommerce) article
This workflow automates the process of summarizing or transcribing a WordPress article, converting the text into speech using Eleven Labs API, and uploading the resulting MP3 file back to WordPress.
How It Works
- Trigger – The workflow starts manually when the user clicks “Test Workflow”.
- Retrieve Article – It fetches a WordPress article based on a given post ID.
- Summarize or Transcribe – An LLM (GPT-4o-mini) generates either: • A summary of the article, or • A full transcription, depending on the chosen prompt.
- Generate Speech – The processed text (summary or transcription) is converted into an MP3 audio file using Eleven Labs API.
- Upload MP3 to WordPress – The generated MP3 file is uploaded to WordPress.
- Update WordPress Post – The article is updated with an embedded audio player, allowing users to listen to the summary or transcription.
Set Up Steps 1. WordPress API Credentials • Configure your WordPress API credentials in n8n. 2. Eleven Labs API Key • Obtain an API Key from Eleven Labs and configure it in n8n. 3. Choose Between Summary or Transcription • Modify the AI prompt to either generate a summary or keep the full transcription. 4. Test the Workflow • Run the workflow and ensure the MP3 file is correctly generated and uploaded.
💡 Customization Options • Modify the AI prompt to switch between a summary and a transcription. • Change the voice model in Eleven Labs for different speech styles. • Adjust output format to higher/lower quality MP3.
🚀 This automation improves content accessibility and engagement by allowing users to listen to a summarized or full version of the article.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
