1.1 What is LINE OA?

LINE Official Account (LINE OA) is a business messaging platform inside the LINE app. It lets brands, businesses, and organizations communicate with their customers through chat — similar to Facebook Messenger for Business or WhatsApp Business, but deeply integrated into LINE's ecosystem.

Unlike a personal LINE account, an OA has special features:

  • Broadcast messages — Send messages to all your followers at once
  • Rich Menu — A persistent menu bar below the chat
  • Auto-reply & Greeting messages — Automated responses
  • Rich Media — Flex Messages, carousels, imagemaps, videos
  • Integration via Messaging API — Programmatic control through webhooks
  • LINE Login & LIFF — Web apps that run inside LINE
  • Analytics & Insights — Followers demographics, message performance
🇪🇩 Thailand Context
LINE is the dominant messaging platform in Thailand with 56M+ monthly active users. LINE OA is used by nearly every major brand — from banks (SCB, KBank) to retailers (Central, 7-Eleven) to restaurants (MK, Sizzler). If your customers are in Thailand, LINE OA is essential.

1.3 LINE OA Plans & Pricing (THB)

Your plan determines how many broadcast/push messages you can send per month. Reply messages (responses to user actions within 5 minutes) are always free.

PlanPrice / monthFree MessagesExtra Message CostBest for
Free฿0300N/ATesting, very small businesses
Basic฿1,28015,000฿0.10/msgSmall-medium business
Pro฿1,78035,000฿0.06/msgGrowing business + CRM

Key rule: Messages are counted per recipient. A broadcast to 10,000 followers costs 10,000 messages from your quota.

💡 Tip: Use Narrowcast (targeted audience segments) instead of broadcast. You'll send fewer messages, save money, and get higher engagement.

1.4 OA Manager GUI — A Quick Tour

LINE OA Manager (manager.line.biz) is the web dashboard. Key sections:

1.5 Messaging API vs OA Manager

You have two ways to control your OA:

ApproachHow it worksWhen to use
OA Manager (GUI)Point-and-click web interfaceManual operations, simple auto-reply, non-developers
Messaging APIYour server + LINE's API via webhooksAutomated bots, custom logic, complex flows, LIFF
BothUse both simultaneouslyMost common. GUI for simple config, API for core logic

This curriculum focuses on the Messaging API + LIFF + LINE Login approach, which gives you maximum control and professional capabilities.

1.6 The 4 Pillars of LINE OA Development

To build a professional LINE OA, master these four areas:

  1. Messaging API — Send and receive messages programmatically
  2. Rich Menu — Persistent navigation for your users
  3. Flex Messages — Rich, interactive UI components
  4. LIFF + LINE Login — Web applications integrated with LINE identity

The remaining modules (Audience, Beacon, MyShop, CRM, Ads) add power on top of these four pillars.

1.7 What You Will Build

By the end of this curriculum, you will be able to build:

  • An automated customer service bot with rich menus and Flex responses
  • An e-commerce experience with MyShop or custom LIFF app
  • A membership/loyalty program with targeted campaigns
  • An integrated marketing system using LINE Ads + Audience segments
  • A proximity-triggered in-store experience with LINE Beacon
