## Introduction
LINE is one of Asia's most popular messaging platforms, with hundreds of millions of users in Japan, Thailand, Taiwan, and beyond.

## Prerequisites
- An active On-Chat account with admin access
- A LINE Official Account (business account)
- LINE Messaging API credentials (Channel Access Token and Channel Secret)
- Access to the LINE Developers Console

## Step 1: Access On-Chat Inbox Settings
Log in to your On-Chat dashboard at app.on-chat.live. Navigate to **Settings** in the left sidebar and click **Inboxes**. Click **Add Inbox** to create a new channel.

## Step 2: Select LINE as Your Channel
Scroll through the channel integration options and select **LINE**. This opens the LINE configuration panel where you will enter your Messaging API credentials.

## Step 3: Get LINE Messaging API Credentials
Log in to the LINE Developers Console at developers.line.biz. Select your Official Account provider, then open your **Messaging API channel**. Copy the **Channel Access Token** and **Channel Secret** from the Basic Settings tab.

## Step 4: Configure the LINE Inbox in On-Chat
Paste your Channel Access Token and Channel Secret into the corresponding fields in On-Chat. Name your inbox (e.g., "LINE Support") and assign it to the team or agents who will handle LINE conversations. Click **Create Inbox** to save.

## Step 5: Set the Webhook URL in LINE Developers Console
Back in the LINE Developers Console, navigate to your Messaging API channel settings and locate the **Webhook URL** field. Paste the webhook URL that On-Chat generated for your LINE inbox. Enable the webhook and click **Verify** to confirm the connection is working.

## Step 6: Test the Integration
Send a message to your LINE Official Account from a LINE user account. The message should appear in your On-Chat inbox within seconds. Reply from On-Chat and confirm that the response is delivered back to the LINE user successfully.

## Best Practices
- Configure LINE rich menus through the LINE Official Account Manager to guide users to common topics
- Use On-Chat automation to send instant welcome messages when new LINE conversations start
- Assign LINE conversations to specialized agents or teams for faster resolution
- Review LINE message analytics in On-Chat to track peak hours and optimize staffing
