Coupang Marketplace Connector

核心功能

Creates and updates Coupang listings directly from your Shopify products, variants and images via the Coupang OPEN API

Near-real-time inventory sync driven by Shopify inventory_levels/update webhooks, respecting your chosen multi-location warehouses

Price sync with a configurable source-of-truth direction (Shopify-led, Coupang-led, or per-field) including KRW currency handling

Order ingestion: Coupang orders are pulled in and created as Shopify orders so fulfillment runs in one place

Fulfillment and tracking sync back to Coupang when you fulfill in Shopify, updating shipment status

Category code and attribute/notice-field mapping using Shopify product metafields, including required Korean-language notice values

Rocket-eligible field handling so Rocket-Growth / fulfillment flags and lead-time fields are populated correctly per listing

SKU matching by barcode or vendor SKU, with safeguards against duplicate or orphaned Coupang listings

Reconciliation reporting that flags out-of-sync SKUs, Coupang-rejected listings and failed sync jobs with error reasons

Configurable sync filters by collection, tag or location so you publish only the catalog you intend to sell on Coupang

Retry-and-backoff queue with logging for Coupang API rate limits and transient failures

Admin-only OAuth connection to Shopify and secure storage of Coupang Wing OPEN API credentials

关于此产品

The Coupang Marketplace Connector bridges your Shopify store and Coupang, South Korea's largest e-commerce marketplace, so you can sell into Korea without manually re-keying catalog, stock or orders.

This is a build-to-order app, not an instant App Store install. After purchase, ECOSIRE configures the connector against your Coupang Wing OPEN API credentials and your Shopify store, maps your data model, and installs it on your shop. You receive a working, tested integration — not a generic plugin you have to wire up alone.

Under the hood it uses the Shopify Admin GraphQL API plus webhooks (products/update, inventory_levels/update, orders/create) to detect changes in near real time, and writes them to Coupang through the Coupang OPEN API. Product metafields drive Coupang-specific fields — category code, notice/attribute values, and Rocket-eligibility flags — that have no native Shopify equivalent. Multi-location inventory is respected, so the warehouse quantities you choose are the ones pushed to Coupang.

Typical scope includes: creating and updating Coupang listings from Shopify products; inventory and price sync with a configurable source-of-truth direction; order and fulfillment sync (Coupang orders pulled into Shopify, tracking pushed back); category and attribute mapping; Rocket-eligible field handling; and a reconciliation report that flags SKUs out of sync, rejected listings and failed syncs.

Because Coupang enforces Korean-language notice fields, strict category attributes and its own approval workflow, a custom build lets us map your catalog structure to those rules rather than forcing your data into a one-size-fits-all template. ECOSIRE handles the build, the install, and ongoing support and updates as Coupang's API evolves.

关于Coupang Marketplace Connector的常见问题

How long until the connector is live on my store?

This is a build-to-order app, so it is configured and installed for you rather than downloaded instantly. Typical delivery is about 10 to 15 business days from when we receive your Shopify access and active Coupang Wing OPEN API credentials. Larger catalogs or complex category mappings can extend that, and we confirm a firm timeline with you before work starts.

What do you need from me to get started?

We need collaborator/admin access to your Shopify store and your Coupang Wing OPEN API credentials (vendor ID plus access and secret keys), which require an approved Coupang seller account. We also need a sample of how your catalog maps to Coupang categories so we can build the attribute and notice-field mapping correctly.

Do you handle Coupang's required category attributes and Korean notice fields?

Yes. Coupang enforces strict per-category attributes and Korean-language notice (상품 정보 고시) fields. We map these from your Shopify product metafields during the build so listings pass Coupang's approval workflow. If certain values do not exist in your data yet, we define metafields for them so your team can maintain them going forward.

Can the connector handle Rocket-eligible listings?

It handles the Rocket-related fields exposed by the Coupang OPEN API — lead-time, fulfillment type and eligibility flags — and populates them per listing based on your mapping. Whether a given product qualifies for a Rocket program is determined by Coupang, not the app; the connector ensures the fields are submitted correctly so eligible products are not blocked by data errors.

What support and updates are included after launch?

Every build includes a post-launch support window covering bug fixes and updates to keep the connector compatible as Coupang's OPEN API changes. After that window, ongoing support and enhancements are available under a maintenance arrangement. Because ECOSIRE builds and hosts the integration logic, fixes and API updates come from us directly — you are not left maintaining undocumented code.

Is sync real-time, and which system wins on conflicts?

Inventory and order changes are near real-time via Shopify webhooks, with a scheduled reconciliation pass as a safety net. You choose the source-of-truth direction during setup — typically Shopify-led for stock and price — so conflicts resolve predictably. The reconciliation report surfaces any SKU where Shopify and Coupang have drifted apart, with the reason and last sync time.
