The workflow runs **AI Damage Analysis (GPT-4o)** to generate a structured report.\n3. The bot then asks the operator to **send a photo of the pallet barcode**.\n4. **AI Barcode Reader (GPT-4o Mini)** extracts the pallet ID from it\n5. Both results (damage report + pallet number) are stored temporarily.\n6. The workflow generates an **HTML report**.\n7. The report is emailed automatically to the quality team.\n\n### Setup\n- [ ] Connect your **Telegram Bot API** to receive images.\n- [ ] Add your **OpenAI API Key** to the Vision nodes.\n- [ ] Connect your **Gmail** credentials.\n- [ ] Update the **recipient email address** in the \u201cSend Report by Email\u201d node. \n\n### Customize\n- **Branding:** update logo, colors and bot name\n- **Damage Analysis**: enrich the report generated by the AI node\n\n"
