Finding expert LINE developers who understand your local market is challenging. We've solved these problems for businesses across Asia-Pacific.
Generic developers don't understand LINE's unique Messaging API, LIFF framework, rate limits, or region-specific features. We've been working exclusively with LINE APIs for over 5 years across 4 countries.
Connecting LINE to your existing systems—CRM, ERP, e-commerce, POS—requires deep knowledge of both sides. We've integrated LINE with over 50 different platforms and can work with your stack.
Solutions that work for 100 users break at 10,000. Our enterprise-grade architecture handles millions of messages with proper queuing, caching, and database optimization.
LINE updates their APIs regularly with new features and deprecations. Our maintenance packages ensure your integration stays current without consuming your team's time.
Customer data flowing through LINE must be protected. We implement bank-level security: signature validation, encryption at rest and in transit, secure token storage, and audit logging.
Traditional agencies take 3-6 months. Our agile approach delivers working software in 2-week iterations. Most projects launch within 4-8 weeks.
LINE specifications differ between Japan, Thailand, Taiwan, and Indonesia. We handle the complexity of multi-region deployments and localization seamlessly.
Miscommunication between your team and developers leads to wrong implementations. Our team communicates fluently in English, Japanese, Thai, and Chinese.
Proven agile methodology adapted for cross-border teams. Clear communication in English, Japanese, Thai, and Chinese.
Free consultation via Zoom, LINE, or in-person. We document requirements in your language, provide transparent estimates, and identify technical challenges upfront. Works across all timezones.
2-week sprints with demos after each cycle. Real-time progress updates via Slack or LINE. You see progress continuously, provide feedback early, and adjust scope as your business needs evolve.
Thorough testing across LINE app versions in different markets. Smooth deployment with rollback procedures. Knowledge transfer documentation in your language. Ongoing maintenance packages for peace of mind.
Receive and process LINE events in real-time. Handle messages, follows, unfollows, postbacks, and custom events. Built on battle-tested infrastructure that handles millions of daily events.
Connect LINE to Salesforce, HubSpot, Shopify, SAP, or any system with an API. Our team has integrated LINE with over 50 different platforms—if it has an API, we can connect it.
Send Rich Messages, Flex Messages, Imagemaps, templates, and broadcasts programmatically. We help you maximize engagement while staying within rate limits and LINE's guidelines.
Store and sync LINE user profiles, conversation history, and custom attributes. Build rich customer profiles that power personalization across all touchpoints.
