LINE OA, LIFF or LINE MINI App: which one does your business need?
Three LINE tools that sound alike but solve different problems. Here is how to choose — with examples from booking and membership projects.
Key takeaways
- LINE Official Account is your business account in LINE. Every business on LINE needs one.
- LIFF lets a web page open inside the LINE chat and know who the customer is — ideal for one focused tool like a booking form.
- LINE MINI App is a complete service that lives inside LINE, built on the same web technology, with extra reach once it is verified.
- Most businesses start with an OA plus the Messaging API, then add LIFF or a MINI App when a real customer journey needs it.
Almost every Thai business that sells to consumers ends up on LINE. The harder question comes next: once you have a LINE Official Account, do you also need a LIFF app, or a LINE MINI App? The names overlap, the documentation assumes you are a developer, and agencies tend to recommend whatever they already build.
This guide explains the three in plain language, from a team that runs bookings, reminders and CRM on LINE every day with FoxConnect.
LINE Official Account: your business’s home in LINE
A LINE Official Account (OA) is the business profile customers add as a friend. From it you can chat one-to-one, broadcast messages to followers, set up greetings and auto-replies, and show a rich menu — the grid of buttons at the bottom of the chat.
On its own, an OA is managed by people in the LINE Official Account Manager. Connect it to the Messaging API and it becomes programmable: your systems can send booking confirmations, answer common questions with a chatbot, or push a reminder the day before an appointment.
- Best for: every business that talks to customers on LINE.
- Development needed: setup only — or Messaging API work for automation.
LIFF: web apps that open inside the chat
LIFF (LINE Front-end Framework) lets a normal web page open inside LINE. With the customer’s permission, the page can read their LINE profile, so they never have to type a name or create an account. It can also send a message back into the chat when they finish.
That makes LIFF the right tool for a single, focused task: a booking form, a digital member card, a product catalogue or a survey. FoxConnect’s booking flow works this way — a customer taps “Book” in the rich menu, picks a time and is confirmed without leaving LINE.
LINE MINI App: a full service without an app download
A LINE MINI App is built on the same web technology as LIFF, but it is packaged as a complete service: think ordering, appointments and memberships in one place. Once a MINI App passes LINE’s review and is verified, it gains extra reach inside LINE, such as being found through search and sending notification-style service messages.
LINE has been bringing LIFF and MINI Apps closer together, so check the current LINE Developers documentation before starting a new build — or ask a LINE developer who works with both.
Side-by-side comparison
| LINE OA | LIFF app | LINE MINI App | |
|---|---|---|---|
| What it is | Your business account in LINE | A web page that opens in the chat | A full service that lives in LINE |
| Customers use it to | Chat, get updates, tap the rich menu | Book, fill a form, show a member card | Book, order and manage a membership |
| Development | Setup; Messaging API for automation | A web app plus the LIFF SDK | A web app plus LINE’s review |
| Best for | Every business on LINE | One or two focused tools | A complete customer journey |
Which one should you start with?
- Start with a well-structured OA. A clear rich menu and good auto-replies solve more than most businesses expect.
- Add the Messaging API when people spend time on confirmations, reminders or the same five questions every day.
- Add a LIFF app when customers need to do one thing — usually book — without leaving the chat.
- Consider a MINI App when LINE becomes the main way customers use your service, not just a way to reach you.
Frequently asked questions
Do I need a developer to set up a LINE Official Account?
No. Anyone can create an OA and set up a rich menu. You need a LINE developer when you want it to connect to your own systems — bookings, CRM, orders — through the Messaging API.
Can a LIFF app use my existing website?
Often, yes. A LIFF app is a web page, so parts of an existing site can be adapted. It usually needs a mobile-first layout and the LIFF SDK to read the customer's LINE profile.
Is FoxConnect a LIFF app or a MINI App?
FoxConnect connects to your LINE Official Account and opens its booking flow inside LINE, so customers book without leaving the chat.
