OpenClaw LINE Integration
Connect OpenClaw to LINE for AI in Asia's favorite messaging app
LINE is the dominant messaging platform in Japan, Taiwan, and Thailand, with over 200 million monthly active users. Beyond messaging, LINE offers payments, food delivery, news, and music - making it a super-app ecosystem. For businesses and developers targeting Asian markets, LINE integration is essential.
OpenClaw makes LINE bot development accessible without deep knowledge of LINE's Messaging API. While LINE provides an official API, it's complex and requires webhook configuration, SSL certificates, and server hosting. OpenClaw abstracts this complexity, giving you a production-ready LINE bot in minutes with natural language configuration.
LINE's business features are particularly powerful. You get rich message templates, quick reply buttons, flex messages (custom card layouts), and LINE Pay integration. OpenClaw exposes these capabilities through simple YAML configuration or conversational setup, allowing you to build sophisticated customer experiences without writing code.

Frequently Asked Questions
Is LINE free for bot developers?
Yes, with limitations. You get 500 free 'push messages' (bot-initiated messages) per month. Reply messages (responses to user messages) are unlimited and free. For businesses needing more push messages, LINE offers paid plans starting at ~$10/month.
Do I need a Japanese phone number?
No. LINE developer accounts are global. You can create a LINE Messaging API channel from anywhere. However, your target users will primarily be in Japan, Taiwan, or Thailand where LINE is popular.
Can my bot work in LINE groups?
Yes, but group chat support must be enabled in your channel settings (LINE Developers → Channel settings → Features → Allow bot to join group chats). Your bot will see all messages in the group.
How do I test my bot before going live?
LINE doesn't have a sandbox mode. Use ngrok or a similar tunneling service to expose your local OpenClaw instance for development. Once ready, deploy to a production server with a proper domain and SSL certificate.
Can I monetize my LINE bot?
Yes. You can integrate LINE Pay for payments, offer premium features, or use the bot to drive traffic to your website. However, spam bots and MLM schemes violate LINE's terms and will be banned.
