Coupang Marketplace Integration connects your Shopify store to Coupang, South Korea's largest e-commerce marketplace, so you can reach Korean shoppers without manually re-keying every listing, price change and order.

This is a build-to-order app, not an instant App Store download. After purchase, ECOSIRE builds the integration against your specific catalog structure, Coupang seller account (Coupang WING / OpenAPI access) and fulfillment model, then installs and configures it on your store. You get a working, tested integration — not a generic plugin you have to wire up yourself.

Under the hood it uses the Shopify Admin GraphQL API to read your products, variants, and multi-location inventory, and webhooks (products/update, inventory_levels/update, orders/create) to keep Coupang in near real-time sync. Listing data — titles, descriptions, options, images — maps to Coupang's category and attribute requirements, and KRW pricing rules convert your Shopify prices using configurable FX margins and rounding so you control your Korean-won shelf price.

The integration handles the full loop: catalog publishing, inventory and price synchronization, order import back into Shopify as native orders, and fulfillment status sync so tracking flows the right direction. Category and attribute mapping is configured to Coupang's taxonomy during setup, bulk upload seeds your initial catalog, and Rocket-fulfillment compatibility flags are surfaced so you know which SKUs qualify.

You stay on Shopify as your single source of truth. ECOSIRE owns the Coupang OpenAPI authentication, error handling, and retry logic — and supports it after launch. Honest scope: Coupang's seller approval, business registration, and any Korea-side logistics are the merchant's responsibility; we integrate the systems, not the marketplace onboarding.
