The Coupang Marketplace Connector is a Magento 2 / Adobe Commerce extension that ECOSIRE builds, installs and supports for sellers expanding into South Korea via Coupang. This is not an instant Adobe Commerce Marketplace download — it is custom-built against your catalog structure, attribute set and fulfillment model, then deployed to your environment and maintained by our team.

Architecturally it ships as a proper Ecosire_CoupangConnector module under app/code, wired through di.xml with service contracts (PHP interfaces in Api/ backed by Model/ implementations) so business logic stays decoupled and testable. Catalog and price publishing run through queue-friendly cron jobs declared in crontab.xml; inventory deltas are captured with observers and plugins (interceptors) on Magento's MSI SourceItem and stock-status save events, so Coupang stock reflects your real availability without full re-syncs. Inbound Coupang orders are pulled on a schedule, normalized, and written via Magento's order service contracts, with shipment and tracking pushed back to Coupang on fulfillment.

The Coupang OpenAPI integration is signed with your seller HMAC credentials, stored encrypted in Magento config, and every call is logged for audit. A dedicated admin section (ACL-gated under Stores > Configuration and a custom menu) gives you category/attribute mapping, bulk listing tools, sync dashboards and retry controls. We expose both REST and GraphQL endpoints where your headless or PIM workflows need them.

Because we build to order, the connector matches Coupang's current category taxonomy, required attributes (brand, model, KC certification fields), and your tax/shipping rules at delivery — not a generic template. ECOSIRE handles installation on Adobe Commerce or Magento Open Source, UAT against Coupang's sandbox, and ongoing updates as Coupang's API evolves.
