        "content": "# 🛍️ Automated Product Description Generation for Adobe Commerce (Magento 2)\n\n## Description\nThis n8n template demonstrates how to automatically generate **product descriptions** for items in **Adobe Commerce (Magento 2)** that are missing one.  \n\nThe workflow retrieves product data, converts raw attribute values (like numeric IDs) into **human-readable labels**, and passes the enriched product data to an **LLM** (Azure OpenAI by default). The LLM generates a compelling description, which is then saved back to Magento using the API.  \n\nThis ensures all products have professional descriptions without manual writing effort.\n\n**Use cases include:**  \n- Auto-generating missing descriptions for catalog completeness.  \n- Creating consistent descriptions across large product datasets.  \n- Reducing manual workload for content managers.  \n- Tailoring descriptions for SEO and customer readability.  \n\n---\n\n## Good to know\n- All **attribute options** are resolved to human-readable labels before being sent to the LLM.  \n- The flow uses **Azure OpenAI**, but you can replace it with **OpenAI, Anthropic, Gemini, or other LLM providers**.  \n- The LLM prompt can be **customised** to adjust tone, length, SEO-focus, or specific brand style.  \n- Works out-of-the-box with Adobe Commerce (Magento 2) APIs, but can be adapted for other ecommerce systems.  \n\n---\n\n## How it works\n1. **Get Product from Magento**  \n   - Retrieves a product that has no description.  \n   - Collects all product attributes.\n\n2. **Generate Description with LLM**  \n   - Resolves attribute option IDs into **human-readable values** (e.g. `color_id = 23 → \"Red\"`).  \n   - Passes the readable product attributes to an **Azure OpenAI model**.  \n   - The LLM creates a clear, engaging product description.  \n   - The prompt can be customised (e.g. SEO-optimized, short catalog text, or marketing style).  \n\n3. **Save Description in Magento**  \n   - Updates the product via the **Magento API** with the generated description.  \n   - Ensures product data is enriched and visible in the webshop immediately.  \n\n---\n\n## How to use\n- Configure your **Magento 2 API credentials** in n8n.  \n- Replace the **Azure OpenAI** node with another provider if needed.  \n- Adjust the **prompt** to match your brand’s tone of voice.  \n- Run the workflow to automatically process products missing descriptions.  \n\n---\n\n## Requirements\n- ✅ n8n instance (self-hosted or cloud)  \n- ✅ Adobe Commerce (Magento 2) instance with API access  \n- ✅ Azure OpenAI (or other LLM provider) credentials  \n- (Optional) Prompt customisations for SEO or brand voice  \n\n---\n\n## Customising this workflow\nThis workflow can be adapted for:  \n- **Other attributes**: Include or exclude attributes (e.g. only color & size for apparel).  \n- **Different LLMs**: Swap Azure OpenAI for OpenAI, Anthropic, Gemini, or any supported n8n AI node.  \n- **Prompt tuning**: Adjust instructions to generate shorter, longer, or SEO-rich descriptions.  \n- **Selective updates**: Target only specific categories (e.g. electronics, fashion).  \n- **Multi-language support**: Generate product descriptions in multiple languages for international shops.  \n\n---\n"
