It’s designed for salons or creative teams that need quick, consistent “hair-only” edits and one-click sharing to a staff group.\n\n### Key Features\n\n* Accepts image and free-form instructions via **n8n Forms**\n* Enforces **identity preservation**: face is not altered; **only the hairstyle** is modified\n* Uses **OpenAI Image Edit** to generate the edited image\n* Uploads the output to **Cloudinary** and returns a public URL\n* Sends the final image to a **LINE group** via the **Push API** (no `replyToken` required)\n* Optional safety: store the **groupId** once (via webhook) in n8n **Data Store** and reuse it, avoiding mis-sending to individuals\n\n### Requirements\n\n* OpenAI API key (Image Edit capable model)\n* Cloudinary account with an **unsigned** `upload_preset`\n* LINE Official Account (Messaging API enabled) and the bot **added to the target group** (to capture `groupId` once)\n* n8n with **Forms** enabled and **Data Store** available\n\n### Notes\n\n* Replace placeholders like `CLOUDINARY_CLOUD_NAME`, `CLOUDINARY_UPLOAD_PRESET`, `LINE_CHANNEL_TOKEN`, and `LINE_GROUP_ID` with your values.\n"
