In today’s competitive e-commerce landscape, building strong relationships with your customers is more important than ever. One powerful way to achieve this is by integrating LINE, one of Asia’s most popular messaging apps, with your online store. With over 200 million monthly active users, LINE offers direct, personal communication that can boost engagement, drive repeat sales, and improve customer support.
In this blog, we’ll walk you through how to integrate LINE with your e-commerce (EC) website, explore the benefits it brings, and share tips for getting the most out of it.
Why Integrate LINE with Your E-Commerce Website?
Before diving into the technical steps, let’s look at why so many brands—especially in Japan—are integrating LINE with their EC platforms:
- Direct communication with customers via 1-on-1 chat
- Instant delivery of promotions, coupons, or order updates
- Personalized support and product recommendations through chatbots
- Higher retention and repeat sales through automated re-engagement flows
- Improved customer experience with seamless login and checkout integrations
Case Study: French beauty brand L’Occitane used LINE as a key digital channel during the pandemic and saw a 600% increase in LINE ad-driven conversions. They used both LINE Ads and account messaging to create an omnichannel experience for their Japanese customers. (source)
Step-by-Step Guide: How to Integrate LINE with Your EC Website
Here’s a step-by-step breakdown to get your LINE Official Account up and running with your website.
Step 1: Create a LINE Official Account
- Go to the LINE Official Account Manager
- Sign in using your personal LINE account
- Under the “Accounts” tab, click “Create new”
- Fill in your business details:
- Account name
- Email address
- The country where the company is located
- Company name (optional)
- Industry and business type
- Purpose for creating a LINE Official Account
- Main usage of the LINE Official Account
- How to connect with your Business Manager
Even if your setup is in English, the business details page may still display in Japanese. If so, consider using Google Translate to assist with completing the fields.
Step 2: Set Up the Messaging API
Once your account is created:
- Navigate to Settings > Messaging API
- Click “Enable Messaging API”
- Set up your developer information (email, privacy policy URL, etc.)
- Create a new Channel
- Copy the following credentials for integration:
- Channel ID
- Channel Secret
- Channel Access Token
Required for most integrations, you can find it in the LINE Developers Console, under your channel’s Messaging API section.
Step 3: Integrate with Your E-Commerce Website
There are two main approaches to integrate LINE depending on your tech stack:
Option A: Use a Plugin or App
This is the fastest and easiest option for non-developers using platforms like Shopify or WooCommerce.
For Shopify:
Install a third-party app like:
- Klaviyo + LINE for combining CRM and messaging
- LINE-powered apps for chat and push notifications
For WordPress/WooCommerce:
Use plugins such as:
- “WP LINE Notify” for notifications
- “L-Clutch” for user authentication
Once installed, configure the plugin using your Channel Access Token and connect it to your LINE Official Account.
Option B: Custom Integration with Messaging API
Ideal for businesses with custom-built sites or developers on-hand.
Here’s what’s typically required:
- Use LINE Messaging API in your backend
- Set up webhook URLs to receive and respond to LINE messages
- Implement logic to:
- Authenticate users using LINE Login
- Push messages for transactional updates
- Handle replies and user interactions
Example: When a customer places an order, your backend sends a message:
“Thanks for your purchase! 🎉 You can track your order [here].”
Use the official LINE Developers documentation for more details.
Popular Use Cases for E-Commerce
Here are some of the most effective ways LINE can enhance your customer journey:
| Use Case | Description |
| LINE Login | Simplify account creation by letting users sign in with their LINE ID |
