• Then click Publish > Deploy as web app using the following settings:
  • Project version - New.
  • Execute the app as - Me (***@gmail.com).
  • Who has access to the app - Anyone, even anonymous.
• Finally click Deploy.
• Next click Review permissions and select your google account.
• (If "This app isn't verified/You should avoid this app" shown, click Advanced > Go to Line main (unsafe) > Allow.)
• Copy this URL and save.

• Back to Line Messaging API.
• Find Webhook URL and click edit.
• Do NOT type short url here.
• Type your Google apps script URL, click Update.
• Turn on Use webhook, 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 re-typing is also good idea.)

• Go to https://free-url-shortener.rb.gy or 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 - How to setup 3DS.

How to setup 3DS

• Start the application and select Line.
• Set your password (if you don't want use password, enter as empty).
• Press L+R button (or tap Change main URL (short)) and type your short url.
• You MUST type short URL with http:// NOT https:// (don't know why but https:// won't work.).
• This method is compatiable with Ver 1.5.0～1.7.0.

How to add friend

• On PC or phone (or android emulator):
  • Find Bot information and scan your bot's QR code or search friends by BOT basic ID.

• On 3DS (this guide compatible with Ver 1.6.0～1.7.0):
  • Press Y button (or tap Add new ID) and type IDs.
  • Select IDs > Tap Receive and press B button (or tap log update).

• If you get No such sheet error:
  • Send "getid" to your 3DS account from your phone/PC account.
  • Then try again.
  • You'll see touch to add this ID and tap it.
