Chatbots & Messaging API
Automatic replies, Flex Messages and notifications sent from your own systems into the chat.
LINE chatbot developmentLINE development
We build on the LINE platform for Thai businesses: LINE Official Accounts that do real work, chatbots on the Messaging API, LIFF apps and LINE MINI Apps, connected to the systems you already run. Our own products, FoxConnect and TellSell, run on LINE every day.
What we build
Everything your customers do in LINE.
Most projects combine several of these. Each of the first three has its own page.
LIFF apps
Booking forms, member cards and catalogues that open inside LINE, with the customer already signed in.
LIFF app developmentLINE MINI Apps
A full service inside LINE with no app to install, listed and searchable in LINE once verified.
LINE MINI App developmentLINE Official Account set-up
Account structure, rich menu, greeting and auto-replies, built as part of the project so the menu opens your own pages and flows.
LINE Login
Sign-in with LINE on your website or app, linked to the customer record in your own system.
CRM & system integration
Every follow, chat, booking and purchase from LINE lands in your CRM, ERP or POS, matched by LINE user ID with consent.

Questions we get asked.
Do you set up LINE Official Accounts?
Yes, as part of a build: account structure, rich menu, greeting and auto-replies, connected to the Messaging API so the account works with your own systems. If you only need ready-made booking and CRM in LINE without custom development, Tellfox (tellfox.app) is a ready-made option.
What is the difference between LIFF and a LINE MINI App?
Both are web apps that open inside LINE. A LINE MINI App has its own channel and, once verified, appears in LINE search. As of October 2026, LINE recommends creating new LIFF apps as LINE MINI Apps.
Can LINE connect to our CRM or ERP?
Yes. The Messaging API sends every event (a follow, a message, a button tap) to a webhook on your server, which can save it against the customer record in your CRM or ERP.
What happened to LINE Notify?
LINE Notify closed on 31 March 2025. LINE recommends the Messaging API for sending notifications; we move LINE Notify alerts over to it.
Do you only build on LINE?
No. We also build web applications, APIs and websites, often as the system behind a LINE project.
