From Coupang and Naver Shopping API integration to Kakao AlimTalk and PG payment gateways — we connect your scattered systems into a unified flow, automating manual work and improving operational accuracy.
Marketplaces, logistics providers, payment processors, notification channels, analytics tools — running a business means using many external services. When these systems don't talk to each other, staff manually move data, errors creep in, and everything slows down. ARC Group builds API integrations that automate the data flow between external services and your internal systems — Coupang API, Naver Shopping API, Kakao AlimTalk, PG payment integration, and more — using a consistent adapter structure designed to stay stable as services evolve.

Integration build & edge-case scenario testing
Production release & initial monitoring
API change response & ongoing stability management
Well-integrated systems reduce repetitive manual work and raise data accuracy.
Tasks that required manual data entry become automated. Your team can focus on meaningful work, not repetitive transfers.
Human input introduces errors. API integration keeps data consistent and accurate across all systems.
An adapter-based design means new channels or services can be added without changing the core — built to grow with your business.
Cost depends on the number of services to integrate, data complexity, and the scope of error handling. We review your requirements in a consultation and propose a specific estimate.
We verify marketplace API credentials, design the data flow for products, orders, and inventory, then proceed through development, testing, and deployment. We also support maintenance for API policy changes.
A Kakao business channel registration and AlimTalk template approval must be completed first. After that, we connect the dispatch API to your internal order and shipping systems to build an automated notification pipeline.
Yes. We first assess the existing system structure, then design the integration to be added without service interruption.
We support maintenance to handle external API version changes and policy updates. The adapter-based architecture keeps the scope of changes minimal.
Yes. We design a single pipeline to manage Coupang, Naver Shopping, 11st, and other channels together. As channels are added, only a new adapter is needed — the core stays the same.
