VBOX Communication with Line Notify

สำหรับตัวอย่างข้างต้น ก่อนทำการทดสอบต้องทำการสมัคร Line Notify ก่อนนะครับ แล้วจึงนำ Token ของไลน์มาใช้งาน

This example shows how to use the LINE Notify to send message into LINE group. When monitoring bit "@test" changes, it will trigger and send the message. Please replace with your own Token.

สร้าง bit ใน vbox ชื่อ "Test" สำหรับเทส

ส่วนของ Lua Scrips.
