[GAS] [PART1] Create and run a bot with LINEnotify that notifies LINE when a specific email arrives at Gmail and marks it as read

Anyway, these days I want to automate various things, but this time it is a method of “notifying LINE when a specific email arrives in Gmail and marking it as read”.

Use LINE Notify

This time, I will try using “LINE Notify”, which has been indebted to me before.

LINE NotifyLINE Notify is a convenient service that allows you to receive notifications from web services such as GitHub, IFTTT, and Mackerel on LINE.

notify-bot.line.me

With this LINE Notify, you can easily create a LINE notification bot. I am very grateful that we are now in an era where anyone can easily create bots.

After logging in with your LINE account, specify a specific group and issue a token. In the case of a group where other people are also participating, everyone will receive a notification, so be careful.

token issuance

A token will be issued. This LINE Notify token will not be displayed again if you close the screen, so be sure to make a copy at this point . If you accidentally close the screen, you will have to start over from scratch.

Prepare variables for tokens

First, let’s put the token we copied earlier into a global variable.

//LINE notify TOKEN
const NOTIFY_TOKEN = "XXXXXXXXXXXXXXXXXXXX";

prepare sendLineMessage() function

After preparing the sendLineMessage() function, set UrlFetchApp.fetch.

function sendLineMessage(){

  const options =
   {
     "method"  : "post",
     "payload" : "message=テスト",
     "headers" : {"Authorization" : "Bearer "+ NOTIFY_TOKEN}
   };
   UrlFetchApp.fetch("https://notify-api.line.me/api/notify",options);
}
