AI Hairstyle Preview Generator with OpenAI and LINE Group Sharing

Description

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.
