'Then click Publish '-> Deploy as web app and set

'finally click deploy.

Next click Review permissions and select your google account.
If "This app isn't verified or You should avoid this app" shown click Advanced and click "Go to Line main (unsafe)" (⁂It's safe!⁂) and click 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 and click Update


And 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 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).
