Claude CodeLINE API

Barber shop booking system (LINE Mini App)

A LINE Mini App for booking haircuts, from the booking screen through to confirmation messages via LINE OA. Built by a shop owner who had never written code.

Built by Community member

What this project is

A LINE Mini App that lets customers book their own haircut, pick a barber and an open slot. The system locks the slot automatically and sends a confirmation through LINE OA.

How Claude built it

  1. Described the booking flow to Claude Code in plain language
  2. Had Claude design the screens and the booking database
  3. Connected it to the LINE Messaging API for confirmation messages
  4. Tested and revised until it held up in real use

The result

  • Time spent replying to chat dropped by more than 80%
  • No more double bookings, since slots lock automatically
  • Three days of work, against a two-month quote from an agency

The hardest part was not the code. It was explaining clearly how the business actually works.
