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