AI Hairstyle Preview Generator with OpenAI and LINE Group Sharing

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.
