About this Product
Coupang is South Korea's largest e-commerce marketplace, and reaching its buyers from Magento 2 means matching Coupang's catalog taxonomy, Korean-language attributes, and order/fulfillment lifecycle — work that no generic connector handles cleanly. ECOSIRE builds this integration to order as a proper Magento 2 module under app/code/Ecosire/CoupangIntegration, wired through di.xml service contracts, plugins/interceptors, and observers rather than core hacks, so it survives upgrades and setup:upgrade.
The extension authenticates to Coupang's Wing/OpenAPI using your seller credentials (HMAC-signed requests) and exposes a dedicated admin section gated by Magento ACL, plus configurable cron jobs for unattended catalog, inventory, price and order synchronization. Product publishing maps your Magento attribute set and categories to Coupang's category and notice/attribute requirements, with a Korean content and attribute mapping layer so listings meet Coupang's localization rules. Inventory and price changes propagate on a schedule or on save via observers; Coupang orders are imported as native Magento orders with address, payment-method placeholder and shipment hooks, including support hooks for Rocket (로켓배송) fulfillment flows.
Because every Coupang seller account, attribute set and SKU structure differs, this is built to order — not an instant Marketplace download. After purchase, ECOSIRE scopes your account, develops against your catalog, installs on your staging then production environment, and supports the module. It runs on both Adobe Commerce and Magento Open Source, integrates with Multi-Source Inventory where present, and ships with clear logging and a re-sync console for operations staff. You own the code.
What you get
- Custom Magento 2 module (Ecosire_CoupangIntegration) delivered as source under app/code with full ownership
- Coupang account scoping: category, attribute and Korean-localization mapping configured against your real catalog
- Installation on your staging then production environment, including setup:upgrade, di:compile and cron registration
- Admin configuration guide and operator runbook for listing, sync and order workflows
- Composer package metadata and version pinning for reproducible deploys
- Post-launch support window with bug fixes and Coupang API change adjustments

Frequently Asked Questions about Coupang Integration
Is this an instant download from the Adobe Commerce Marketplace?
No. This is a build-to-order extension. There is no instant Marketplace download. After purchase ECOSIRE scopes your Coupang seller account and Magento catalog, builds the module against your environment, and installs it. You receive the full source under app/code and own the code.
How long until it's installed and live?
Typical delivery is around one working week depending on catalog size, Coupang category and Korean-attribute mapping complexity, and how many SKUs need publishing. We confirm a firm timeline during scoping after purchase, develop on staging first, then deploy to production with you.
Do I get ongoing support and updates after launch?
Yes. Every build includes a post-launch support window covering bug fixes and adjustments when Coupang changes its Wing/OpenAPI (endpoints, signing or category requirements). Extended support and enhancement retainers are available, and because you own the source your own team can also maintain it.
Does it work on both Adobe Commerce and Magento Open Source?
Yes. The module targets Magento 2.4.x on both Adobe Commerce (Enterprise) and Magento Open Source. It is Multi-Source Inventory aware where available and adapts to your inventory model during scoping.
Will it survive Magento upgrades?
Yes. It is built as a standard module using di.xml, service contracts, plugins/interceptors and observers — no core file edits. Upgrades are applied with setup:upgrade and di:compile, and the module is version-pinned via Composer so deploys are reproducible.
