Line for 3DS

Discord channel : https://discord.gg/Zmx7Euf

Dead link in SETUP.md has been fixed, so version number in links were changed to v2.0.0.1.
Software (source code) is identical to v2.0.0

From v2.0.0, setup instructions have been moved to github.
You can find the link below.

v2.0.0
  • Line
    • Significant changes for internal code, so you need to setup your Google Apps Script again.
    • Setup instructions are updated.
    • 3DS
      • Chat log wrapping feature has been improved a lot.
      • Auto update feature (for chat logs) are removed temporary.
      • Clear cache feature (for downloaded files) are removed temporary.
    • Google Apps Script
      • Self tests are added so that it is much easier to trouble shoot.
  • Camera
    • Supported QR code scan (currently, only for Google Apps Script setup).
  • Video player
  • Overall
    • Application folder has been changed from /Line/ to /3ds/Line/ (old folder won't be deleted automatically, but you can delete it if you don't need it).
    • Sub application icon has been added.

Back to Line Messaging API
Find Webhook URL and click edit.

⁂ DO NOT TYPE SHORT URL HERE ⁂
Type your Google apps script URL and click Update

And turn on Use webhook
5dc4172fb531eacaf26757aa3fdb1b64.png

Click verify to check webhook works fine.
Check result and if "success" wasn't displayed, double check your Google apps script URL..
(delete whole url once and retyping is also good idea)

Please open https://free-url-shortener.rb.gy/ , https://tiny.cc/ or https://tinyurl.com/
Then shorten your Google apps script URL.
Your URL should be
http://tinyurl.com/****** or http://tiny.cc/****** or http://rb.gy/******
This short URL is needed by next section.
Then go to (Guide) How to setup (3DS).

If you have any problems fell free to ask me on this discord server.

Download this

Set your password (if you don't want use password, enter as empty).

For ver 1.5.0～1.7.0


  1. This guide compatible with ver 1.5.0～1.7.0

    Next step there are 2 methods
    Press L + R button (or tap Change main URL (short)) and type your short url
    You MUST type short URL with http:// NOT https:// (I don't know why but https:// won't work.)

    I do NOT recommend this method because it is hell ;(
    if you want to type whole URL, press X button (or tap Change main URL) and type your google apps script URL.

Then go to (Guide)How to add friend.

I don't know how Line works, but it feels like it shouldn't be impossible :) What happens in the 3DS if you send a stamp or picture from the phone?
Click to expand...

Send from 3DS
3DS -> Google server -> LINE server -> line app
Send from line app
line app -> LINE server -> Google server -> save to message log google server -> 3DS(Request data to google and receive data)

I will write tutorial how to use line on 3DS. But it will write a little later.

If you send picture, video, sound, or stamp. 3DS will be displayed "undefined".

This looks awesome!

How'd you do this?

I'd be interested to see if something similar could be done w/ Discord, but this is genuinely awesome this is what homebrew this community needs.
