Things your AI can do in LINE
Your FormWise AI can handle any of these in LINE — on its own, without you needing to click a button.
Create Rich Menu
Create a rich-menu definition and return its ID. Creation alone does not display it: upload an image, then set it as default or link it to a user.
Create Rich Menu with Image
Create a rich-menu definition and upload its JPEG or PNG image in one call. If image upload fails, the newly created definition is deleted automatically. The finished menu must still be set as default or linked to a user to display.
Delete Rich Menu
Permanently delete a rich menu by ID. Delete only a menu the caller owns or explicitly intends to remove.
Download Message Content Preview
Download LINE's reduced-size preview image for a retained image or video message whose contentProvider.type is line.
Get Message Delivery Count
Get the number of reply, push, multicast, or broadcast messages sent on one UTC+9 calendar date. A result can be unready, unavailable_for_privacy, or out_of_service instead of containing a count.
Get Rich Menu
Get one Messaging API rich-menu definition by ID, including its canvas, tappable areas, and actions.
Link or Unlink User Rich Menu
Link or unlink a per-user rich menu. WARNING: LINE can return HTTP 200 even when nothing changed for a nonexistent, deleted, blocked, non-friend, or cross-channel user; success confirms request acceptance, not the assignment effect.
List Chat Member IDs
Return one page of member user IDs for a group or legacy room containing the bot. Requires a verified or premium LINE Official Account; room applies only to legacy multi-person chats.
List Follower IDs
Return one page of user IDs for friends of the LINE Official Account. This endpoint requires a verified or premium LINE Official Account and excludes blockers, deleted users, and users without profile consent.
List Rich Menus
List all rich menus created through the Messaging API. Menus created in LINE Official Account Manager are not included.
Mark Messages as Read
Mark all messages through a webhook-issued read token as read. The token must have been received by this exact bot; this operation cannot be undone.
Set or Clear Default Rich Menu
Set or clear the Messaging API default rich menu. Setting requires an image-backed rich menu; clearing does not delete the menu and does not clear a default managed in LINE Official Account Manager.
Show 1 more thing it can do
Upload Rich Menu Image
Upload a JPEG or PNG image for a rich menu. An image cannot be replaced for the same rich-menu ID; create a new menu to use another image.
Built for the way you actually work
No code, no engineers
Connect in a few clicks and start using your AI right away. If you can use the apps you already love, you can do this.
Sounds like you, not like a bot
Train your AI on your offer, your voice, and the way you actually talk to clients — it picks up where you leave off.
Plugs into the stack you already use
No need to rip out your CRM, your scheduler, or your email tool. Your AI works inside the apps running your business today.
Your data stays yours
Client conversations, lists, and credentials are scoped to your workspace. Nothing gets shared, sold, or used to train anyone else’s AI.
What you can do once LINE is connected
Onboard new clients without lifting a finger
When someone signs up, your AI greets them, sets up their next step in LINE, and keeps the momentum going — even at 2am.
Reply to leads in seconds, not days
Your AI watches LINE for new inquiries, answers questions in your voice, and books the call before they cool off.
Get your weekends back
Hand off the repetitive LINE work — follow-ups, reminders, updates, simple admin — and stop being the bottleneck in your own business.

Questions other LINE users had before signing up
Do I need to know how to code?
Not even a little. If you can use LINE today, you can set this up. You'll connect LINE, tell your AI what it should help with, and you're live. The whole thing is built for coaches, course creators, agencies, and operators — not engineers.
Will my clients know they're talking to an AI?
Only if you want them to. Your FormWise AI is trained on your voice, your offer, and the way you actually communicate — so it sounds like a thoughtful team member, not a clunky chatbot. Most people can't tell.
Can I make it sound like me?
Yes. You can give your AI examples of how you write, the questions you usually ask new clients, the way you handle objections, and the language you use about your offer. The more you give it, the more it sounds like you wrote it.
What if I want to take over a conversation?
You're always in control. You can step in at any point, take over from your AI, or stop it from sending messages until you've reviewed them. Think of it as a teammate, not a replacement.
Is my client data safe?
Yes. Your LINE login and client information stay scoped to your workspace. We don't sell it, we don't share it, and we don't use your data to train anyone else's AI. You can disconnect LINE or delete everything any time.
What happens when LINE updates their app?
We handle it. When LINE adds new features or changes how something works, we update the integration in the background. You don't have to do anything — your AI just keeps working.
How fast can I actually get this running?
Most people are up and running the same day they sign up. Connecting LINE takes a few minutes. Teaching your AI to handle the work the way you'd want it done is the part worth slowing down for.
What is FormWise?
FormWise is the AI agent builder for coaches, course creators, and agencies. You connect the apps you already use — like LINE — train your AI on your offer and voice, and let it handle the work you've been doing manually: onboarding, follow-ups, support, admin. No code, no developers, no engineering team required.
Can I sell AI agents to my clients?
Yes. A lot of FormWise users build AI assistants and sell them as part of their offer — done-for-you AI setups, white-label assistants for client businesses, custom GPTs trained on a client's brand. You can charge a setup fee, a monthly retainer, or both.
Can I embed my AI on my website or in my course?
Yes. Every AI you build in FormWise can be embedded on your site, dropped into your course platform, or shared as a standalone link. Your clients and students just open it like any other web page — no app to download, no login hoops.
Do I need to know anything about AI to use this?
No. If you can describe what you want your AI to do in plain English — "greet new clients, ask these 3 questions, book them a call" — FormWise can build it. We handle the models, the prompts, the connections. You handle the part you already know: what your business actually needs.
