LINE Official Account AI Auto-Reply Tutorial | ClawCloud 10-Minute Setup

It's 2 AM. A customer messages your LINE Official Account asking "do you still have it in stock for tomorrow?" By the time you wake up, they've already read your unanswered reply and bought from a competitor.

Most small businesses in Taiwan lose orders this way every day. An AI assistant doesn't sleep — but how do you actually wire one up to LINE without spending a week on webhooks and SSL certs?

With ClawCloud, the whole flow collapses to 10 minutes, no code. This guide walks each step.

Why connect AI to LINE Official Account?

LINE is Taiwan's primary messaging channel — 21M+ monthly active users. For small businesses, the LINE Official Account is the storefront. The catch: messages arrive whenever, and an unanswered one is a lost customer.

With AI in the loop you get three things:

1. Always-on instant replies. Late nights, weekends, holidays — AI answers FAQs (hours, location, prices, stock) without you lifting a finger.

2. Concurrent conversations don't pile up. Human agents serialize; AI doesn't. Peak hours, promotions — none of it queues.

3. Lower headcount. AI handles ~70% of repetitive questions; the remaining 30% (the ones that need judgment) go to a human. A small team punches above its weight.

Now let's set it up.

Step 1: Create a LINE OA and enable Messaging API

LINE has consolidated OA creation and Messaging API setup into LINE Official Account Manager — you no longer need to manually create a Channel from the Developers Console first. The flow is much simpler than older tutorials describe.

Visit manager.line.biz and sign in with LINE
If you don't have an OA, click "Create a LINE Official Account" and fill in the basics (industry, contact email, business name). You'll receive a LINE ID like @abc1234d
Inside the OA dashboard: Settings → Messaging API → Enable Messaging API
Pick (or create) a Provider when prompted — just use your brand name
Once enabled, the OA is automatically linked to a Channel in the LINE Developers Console

Now grab two credentials from the Developers Console — these are what ClawCloud uses to reply on your behalf:

Channel access token (long-lived): your Channel → Messaging API tab → bottom of the page, click Issue
Channel secret: the Basic settings tab on the same Channel

Copy both. You'll paste them in the next step.

Step 2: Connect LINE in the ClawCloud Dashboard

Open the ClawCloud Dashboard and sign in. New accounts get 1,000 free credits automatically.

If this is your first visit, click Start AI Agent on the dashboard and wait 1-2 minutes for the agent to come online.

Once the agent is running, you'll see a list of channel cards: Web, Telegram, LINE Official Account.

Click Add LINE on the LINE card and paste:

Channel Access Token: the long token you issued
Channel Secret: from Basic settings

Click Connect. The card turns green ("Connected") and shows a Webhook URL that looks like:

https://clawcloud.live/api/v1/channel/line/<your-user-id>

Click Copy next to it, then go back to LINE Developers Console → Messaging API tab:

Webhook URL field → paste → Update → Verify (must show Success)
Toggle Use webhook to Enabled
Toggle Auto-reply messages to Disabled (LINE's built-in canned replies will fight your AI if left on)
Greeting messages — keep or disable, your call

Step 3: Pick a template, paste your knowledge base

After connecting, the LINE card shows a Settings → button. Click it to land on /dashboard/line. Two things to do here — and they directly determine how accurate your AI is.

Pick a persona template

ClawCloud ships with four templates. Click the closest match:

Restaurant — menu, hours, reservations, delivery, location
E-commerce — products, stock, order tracking, returns
Registration — event details, signup process, pricing, who it suits
Blank / Custom — no preset persona; let the knowledge base do all the work

Picking auto-saves. No agent restart needed — your next LINE message uses the new persona.

Paste your knowledge base (the most important step)

The template defines the AI's tone. The knowledge base defines what the AI knows. Paste anything you want it answering from:

Hours, address, parking
Menu, prices, product list
Returns policy, shipping cost, delivery times
30-50 FAQs (the more specific, the better)
Anything unique to your business that the AI couldn't know otherwise

The textarea holds ~10,000 characters — comfortably 30-50 QAs. One per line is the sweet spot.

Click Save knowledge base. The next LINE message uses the updated content immediately.

Step 4: Configure handoff to a human

Not every question should go through the AI. When a customer says "I want to talk to a real person" or "agent please", you want the AI to step aside.

In the same page, Hand off to a human section:

Trigger keywords: comma-separated. Defaults to 我要找客服, 請接給人, 人工客服, 真人客服 (add/remove as you like, or add English equivalents)
Telegram notification: when on, ClawCloud pings you on TG with the customer's LINE name + the trigger word + the original message — so you don't need to refresh the dashboard

Heads up: TG notifications require you to connect Telegram from the Dashboard first. Without it, the toggle is greyed out.

When triggered, the LINE user receives "A human will reply shortly", and the AI stops replying to that user until you manually flip handoff back. In /dashboard/line/conversations you'll see an orange "HANDOFF" badge on the affected session.

Step 5: Go live and test

On your personal LINE app, search your bot's basic ID (visible in LINE Developers Console → Basic settings → Bot basic ID, e.g. @abc1234d) and add as a friend.

Send a test message like "what are your hours?" — if you covered it in Step 3's knowledge base, the AI should respond instantly.

If nothing comes back, check three things:

LINE Developers Console → Messaging API → Verify button must show Success
ClawCloud LINE card status must be green ("Connected")
Auto-reply messages must be Disabled

90% of "no reply" issues trace to #3 — LINE's built-in auto-replies racing the webhook.

After going live

Connecting it isn't the end — it's the start. Spend 10 minutes a day for the first week on these:

1. Read the conversation log. /dashboard/line/conversations shows every customer's full thread with the AI. You'll quickly see what's working and what's not.

2. Top up the knowledge base. Whenever a customer asks something you didn't anticipate, add that line to the knowledge base. Next time the AI handles it. The faster you iterate here, the bigger the gap between you and competitors.

3. Manage handoff threads. In the conversations page you can see which sessions are in handoff mode. Once you've replied as the human, click Hand back to AI on that session and the AI resumes for future messages.

After a week you'll see the AI handle 70-85% of inbound, with humans only touching the messages that genuinely need judgment.
