Step-by-Step Integration Guide

Step 1: Create Your Chat Data Chatbot

Before connecting to LINE, set up your chatbot in Chat Data:

1. Log into your Chat Data dashboard
2. Create a new chatbot or select an existing one
3. Train your chatbot by uploading documents, adding Q&A pairs, or connecting data sources
4. Configure your AI's personality, response style, and behavior settings
5. Test the chatbot in the Chat Data interface to ensure it responds appropriately

Your chatbot's knowledge base and configuration will power all responses on LINE, so take time to train it well.

Step 2: Access LINE Integration in Chat Data

Navigate to the LINE integration settings:

1. Go to Dashboard > [Your Chatbot] > Integrations
2. Locate and click the LINE integration card
3. Click the Add to LINE button

A modal window will appear displaying your unique webhook URL. Keep this modal open—you'll need the webhook URL in Step 5.

3. Configure the following toggles:

   • Chat: Turn ON (enables message handling)
   • Webhooks: Turn ON (routes messages to Chat Data)

4. Auto-response messages: Turn OFF (prevents conflicts with your AI chatbot)

5. OPTIONAL: Greeting message: Turn ON if you want to send an automated welcome message when users first add your account

6. Click Save at the bottom of the page

Advanced Configuration Options

Delayed Message Sending

Create more natural, human-like conversations by adding a configurable delay before your AI chatbot responds. This feature makes interactions feel less robotic and gives users time to read previous messages.

To configure delayed messaging:

1. In the Chat Data LINE integration modal, locate the Response Delay section
2. Enter a delay value in seconds (e.g., 2-5 seconds for natural pacing)
3. The AI will wait the specified duration before sending responses
4. This applies to all messages sent through the LINE integration

Benefits:

• More natural conversation flow that mimics human response times
• Prevents overwhelming users with instant, rapid-fire responses
• Gives users time to process information before receiving the next message
• Improves overall user experience and engagement

AI Re-engagement

Keep conversations active by automatically following up with users who haven't responded. Chat Data's AI can intelligently decide when to send contextual follow-up messages based on conversation history.

Configure AI re-engagement with three customization aspects:

1. Time Window: Set how long to wait before sending a follow-up (e.g., 24 hours, 3 days, 1 week)
2. Trigger Conditions: Define when follow-ups should be sent (after providing information, incomplete transactions, etc.)
3. Message Style: Customize the tone and content of re-engagement messages to match your brand

The AI evaluates each conversation's context to determine:

• Whether a follow-up is appropriate based on the last interaction
• What information to include in the follow-up message
• The optimal tone (helpful reminder, new information, check-in, etc.)

Use Cases:

• Follow up on product inquiries that didn't convert to purchases
• Check if previous answers resolved the user's question
• Share new information relevant to previous conversations
• Re-engage users who started but didn't complete a process

Live Chat Handover

Seamlessly transition from AI automation to human support when conversations require personal attention, complex problem-solving, or empathetic communication.

To take over a conversation from the AI:

1. Access your Live Chat dashboard in Chat Data
2. Use filters to view LINE conversations specifically
3. Select the conversation thread you want to handle
4. Toggle the AI chatbot switch to OFF
5. Begin responding as a human agent—the user sees your messages in LINE

Key Features:

• Full conversation history is preserved when transferring between AI and human agents
• Users continue chatting in LINE without switching platforms or creating tickets
• Email notifications alert you when customers respond during offline hours
• Re-enable the AI chatbot toggle when you're done to resume automation

When to Use Live Chat Handover:

• Customer requests to speak with a human agent
• Complex technical issues requiring expert knowledge
• Sales conversations that benefit from personal touch
• Situations requiring empathy or emotional intelligence
• Complaints or sensitive matters

To resume AI automation after resolving the issue, simply toggle the AI chatbot switch back to ON in the Live Chat dashboard.

Automatic AI Chatbot Pause

Configure automatic pausing of AI responses when human agents take over conversations. This prevents the AI from interfering during human-led interactions and ensures a smooth handover experience.

To configure automatic pause:

1. During the LINE integration setup, locate the Auto-Pause AI section
2. Toggle the feature ON
3. Set the pause duration (available options: 1 hour, 6 hours, 24 hours, 3 days, or 1 week)
4. Save your configuration

How It Works:

• When you manually respond to a user in Live Chat, the AI automatically pauses
• All subsequent messages from that user bypass the AI and go directly to your Live Chat inbox
• You receive email notifications for each new message during the pause period
• After the configured duration, the AI automatically resumes handling that conversation
• Users experience no interruption—they continue chatting in LINE normally

Benefits:

• Prevents AI from responding while you're actively helping a customer
• Ensures consistent communication from a single source (human OR AI, not both)
• Gives you time to resolve issues without AI interference
• Automatically resumes AI support so you don't have to remember to turn it back on
• Ideal for overnight or weekend support—AI pauses during business hours, resumes after

This feature is especially useful for businesses with defined support hours who want AI to handle after-hours inquiries while humans manage daytime conversations.

Media File Support

Your Chat Data AI chatbot automatically handles rich media through the LINE integration, supporting multiple file types for enhanced communication.

Supported Media Types:

• Images: Automatically processed and analyzed by the AI chatbot with format conversion handled seamlessly
• Video: Automatically processed with format conversion handled by Chat Data
• Audio: Audio messages and voice notes are automatically processed with format conversion
• Files: Document files (PDFs, spreadsheets, etc.) are provided directly to users as downloadable URLs

How Media Handling Works:

Chat Data automatically handles all format conversion for images, video, and audio—you don't need to worry about specific formats or technical specifications. When users send these media types through LINE, your AI chatbot can analyze and respond contextually to the content.

For file attachments like PDFs or spreadsheets, Chat Data provides them as direct download URLs to users, ensuring seamless document sharing without additional processing.
