1Common Challenges
Nobody wants another app
Asking customers to download an app for a member card or a booking adds a step many won't take. A LINE MINI App opens from a chat, QR code or rich menu with no install.

LIFF & LINE MINI App development
We build custom web apps that open inside LINE — member cards, booking and queue pages, mobile ordering, sign-up forms — with LINE Login built in. Following LINE's recommendation since February 2025, new projects start as LINE MINI Apps unless LIFF fits better.

Common Challenges
Why businesses want an app inside LINE
Your customers already have LINE open. A separate app download or website sign-up is where they drop off.
2Common Challenges
Forms that forget the customer
Web forms ask for a name and phone number every time. Inside LINE the user is already identified through LINE Login, and verified MINI Apps can offer Common Profile Quick-fill.
3Common Challenges
Two native apps to maintain
iOS and Android each need their own builds, store reviews and updates. A MINI App is one web codebase that runs inside LINE on both — and in ordinary browsers too.
4Common Challenges
LIFF or MINI App?
In February 2025 LINE announced that LIFF will be integrated into the LINE MINI App and recommended building new LIFF apps as MINI Apps. Picking the wrong channel type costs time later.
5Common Challenges
Verification rules differ by country
Since March 2026 anyone permitted can publish an unverified MINI App in Thailand and Taiwan, but verified status there requires a certified provider. Japan has its own review path.
6Common Challenges
Notifications with strict rules
Service messages may only confirm or answer what the user did. Promotions belong in your LINE Official Account.
How It Works
How a LIFF or MINI App project runs
Every project starts with the contact form and is quoted once the scope is clear.
1
Tell us the use case
Contact form: what customers should do in LINE, where they start (rich menu, QR code, chat), which systems are involved, and your service region — Japan, Thailand or Taiwan.
2
Scope, route & quote
We recommend a LINE MINI App or LIFF, verified or not, list LINE's requirements (policy, review, provider status) and send a written scope with the price.
3
Design, build & test in LINE
Screens designed for LINE's in-app browser, built on LIFF SDK v2 with LINE Login, and tested on iOS and Android — inside LINE and in a regular browser.
4
Review & handover
We help prepare the channel settings and, where it applies, the verification submission, then hand over the code and documentation as agreed.
Key Features
What we build as LIFF and LINE MINI Apps
Custom builds on request — none of these are LineBot.pro self-serve features.
Digital member cards
A member card with a QR code or barcode, showing points or tier from your own system, opened from the rich menu.
Booking & queue pages
Pick a slot or take a queue number inside LINE; on verified MINI Apps the confirmation can arrive as a service message.
Mobile ordering
Table or pickup ordering connected to your menu and POS, with payment through the provider that fits your market.
Forms & registrations
Event sign-ups, warranty registrations or surveys, with the LINE user already identified and an optional prompt to add your LINE Official Account as a friend.
Coupons & stamp cards
Digital coupons and stamp cards that follow your own rules and data.
LINE Login built in
Customers are recognised without passwords; verified MINI Apps can also use channel consent simplification and Common Profile Quick-fill.
Connected to your systems
POS, booking software, CRM or e-commerce backend connected through their APIs, so the app shows your real data.
Notifications within LINE's rules
Service messages for confirmations on verified MINI Apps; everything promotional goes through your LINE Official Account.
Works in a browser too
The LINE MINI App Policy requires the endpoint to work in browsers such as Safari and Chrome, and since 1 October 2025 all users can open MINI Apps there.
LIFF vs MINI App
LIFF or LINE MINI App? (October 2026)
The differences that drive the decision, based on LY Corporation's documentation.
| LIFF app (LINE Login channel) | LINE MINI App — unverified | LINE MINI App — verified | |
|---|---|---|---|
| Status | Still supported; LINE plans to integrate LIFF into LINE MINI App | LINE's recommended starting point for new apps | Same, after passing LINE's review |
| Who can publish | Add it to any LINE Login channel | Anyone permitted by the MINI App Policy (Japan since Nov 2024; Taiwan and Thailand since 11 Mar 2026) | After the verification review — in Taiwan and Thailand only for channels under a certified provider |
| Header shows | — | Title + your domain | Title + MINI App name + verified badge |
| Screen size | Full, Tall or Compact | Full | Full |
| Service messages, home-screen shortcut, Custom Path, Quick-fill | — | Not available | Available |
| Found from LINE's Home tab and search | — | No | Yes |

Build it, or use a package?
LineBot.pro's self-serve tools don't include booking, membership, ordering or loyalty features — those are apps we build for your business on request. If a ready-made package already covers your need, we'll tell you — in Japan, LY Corporation lists certified packages on its LINE MINI App site (it also publishes the 28.97M monthly-user figure for Japan).

Contact UsFrequently Asked Questions
Frequently Asked Questions
What's the difference between LIFF and a LINE MINI App?
Both are web apps that run inside LINE. A LIFF app is added to a LINE Login channel and can use the Full, Tall or Compact screen size. A LINE MINI App has its own channel with one Full-size web app and — once verified — extras such as service messages, a home-screen shortcut, Custom Path and discovery from LINE's Home tab and search. In February 2025 LINE announced that LIFF will be integrated into the LINE MINI App and recommended creating new LIFF apps as MINI Apps.
Can businesses in Thailand and Taiwan publish a LINE MINI App?
Yes. Since 11 March 2026, anyone permitted by the LINE MINI App Policy can create a MINI App channel for Thailand or Taiwan and publish it as an unverified MINI App. Applying for verified status there requires a channel under a certified provider. In Japan, permitted businesses have been able to publish since November 2024.
How much does LINE MINI App development cost?
It depends on the screens, the integrations (POS, booking, payments), the languages and whether you aim for verified status, so we quote each project after scoping it. For standard needs a ready-made package can be cheaper — in Japan, LY Corporation lists certified packages — and we'll tell you when that's the better route.
Do customers need to download anything?
No. The app opens inside LINE from a chat link, QR code, rich menu or message. Since 1 October 2025, all users can also use LINE MINI Apps in a regular web browser.
What is a verified MINI App, and do I need one?
It's a MINI App that passed LINE's verification review. Its header shows your MINI App name and a verified badge, and it unlocks service messages, home-screen shortcuts, Custom Path, Common Profile Quick-fill and discovery from LINE's Home tab and search. Unverified apps work too, but the header shows your domain and those features aren't available.
Can a LINE MINI App send notifications?
Verified MINI Apps can send service messages, but only to confirm or respond to something the user did — a booking, for example — never ads or promotions. They appear in a dedicated LINE chat for each region. Promotions go through your LINE Official Account, where messages count toward your plan.
Can a LINE MINI App take payments?
Yes, MINI Apps can integrate payment services, and in Japan an in-app purchase feature for digital content has been officially available since February 2026. The right payment provider depends on your market; we confirm it while scoping.
Is LIFF or MINI App development part of LineBot.pro's self-serve tools?
No. LineBot.pro's tools create rich menus, rich messages and banners and automate replies and campaigns. LIFF and LINE MINI App projects are custom development on request — start with the contact form.
Can you migrate our existing LIFF app to a LINE MINI App?
We can review it and plan the move. LINE has said existing LIFF apps can keep being used, and it announced a way to migrate LIFF apps on LINE Login channels to LINE MINI Apps; we check the options available at the time we scope your project.
