LINE

Connect a LINE Official Account and your AI agent answers customers messaging you on LINE. LINE is one of the biggest messaging apps in Japan, Thailand, and Taiwan — prioritize it if that’s where your customers are. Setup takes a channel secret and an access token; ChatterMate registers the webhook for you.

​
What you’ll need

  • A LINE Business ID (free).
  • A Messaging API channel in the LINE Developers console.

​
Step 1 — Create a Messaging API channel and get your keys

1

Create a provider and channel

Go to the LINE Developers Console → create a Provider (your company) → Create a Messaging API channel. Fill in the channel name, description, and category.This also creates a LINE Official Account you manage at manager.line.biz.
2

Copy the Channel secret

On the channel’s Basic settings tab, copy the Channel secret. ChatterMate uses it to verify incoming webhook signatures.
3

Issue a Channel access token

On the Messaging API tab, issue a long-lived Channel access token and copy it. This lets ChatterMate send replies.
4

Turn off auto-reply

In the Official Account Manager → Settings → Response settings, turn Auto-reply messages off and enable Webhooks, so your AI agent (not LINE’s canned replies) answers customers.

​
Step 2 — Connect in ChatterMate

1

Open the LINE card

Go to Settings → Integrations and click Connect on the LINE card.
2

Paste your keys

Enter the Channel secret and Channel access token. ChatterMate stores them encrypted and registers the webhook automatically — you don’t need to paste a webhook URL into the LINE console.
3

Assign an AI agent

Choose the AI agent that answers LINE and click Assign agent.

​
Step 3 — Test it

Add your Official Account as a friend (scan its QR code from the Official Account Manager) and send a message. The AI agent replies — with a LINE loading animation while it thinks — and the chat appears in Conversations with a LINE badge.
No heavy approval is needed to send and receive messages — a working Official Account is enough. A Verified or Premium badge (blue/green) is optional; apply for it in the Official Account Manager if you want the verified checkmark (LINE reviews the business over a few days).
