eBay Marketplace Connector

Key Features

Product listing creation and revision via eBay Inventory & Offer APIs, driven by reusable listing templates mapped from Magento attributes

Real-time inventory sync from Magento stock to eBay availability through observers on stock-item save events, with multi-source inventory (MSI) awareness

Automatic price sync, including configurable markup/markdown rules and per-website price scope handling

eBay order import on cron into native Magento orders with customer, shipping address, payment placeholder, and tax mapping

Category mapping from Magento categories to eBay category IDs, plus item-condition mapping (New, Used, Refurbished, etc.)

Bulk listing management — list, revise, end, and relist many SKUs from a dedicated admin grid with mass actions

Attribute-to-aspect mapping UI so Magento attributes (brand, color, size, MPN) populate eBay item specifics correctly

OAuth2 connection management with automatic token refresh and sandbox/production environment switching

Per-action sync logging in a custom table with retry, error surfacing, and a status dashboard under a dedicated admin ACL

Message-queue-backed async sync (Magento\Framework\MessageQueue) so large catalog pushes never block the admin or storefront

eBay business-policy mapping (payment, shipping, return) so listings comply with seller account requirements

Optional REST/GraphQL trigger endpoints for headless or external ops tooling to initiate listing and inventory syncs

About this Product

The eBay Marketplace Connector turns your Magento 2 / Adobe Commerce catalog into a managed eBay sales channel — no copy-pasting SKUs into Seller Hub, no inventory drift, no oversells. ECOSIRE builds this as a first-party module under app/code/Ecosire/EbayConnector, wired into the eBay Sell APIs (Inventory, Listing/Offer, Fulfillment, Account) with OAuth2 token refresh handled server-side.

This is not an instant Marketplace download. It is a build-to-order engagement: we scope your catalog, attribute structure, and eBay business policies, then build, install, and configure the module directly on your Magento instance (self-hosted, cloud, or Adobe Commerce on cloud) and support it afterward.

Architecturally it follows Magento conventions you can audit and own. Product/stock changes are captured via observers on catalog_product_save_after and cataloginventory_stock_item_save_after, queued, and pushed to eBay through a service-contract layer (Api/EbaySyncManagementInterface) so business logic stays decoupled from the API client. di.invoke preferences and plugins/interceptors let us extend price and inventory behavior without core hacks. eBay order import runs on cron via Magento\Framework\MessageQueue, creating native Magento orders with correct customer, address, and tax mapping. A dedicated admin section with its own ACL resources (Ecosire_EbayConnector::config, ::listings, ::logs) exposes attribute-to-eBay-aspect mapping, category and item-condition mapping, listing templates, and a sync dashboard. Errors are logged to a custom table with retry, and every API call respects eBay rate limits.

Works on Magento Open Source and Adobe Commerce 2.4.x, multi-store and multi-website aware, with optional GraphQL/REST endpoints if your ops tooling needs to trigger syncs programmatically.

What you get

A first-party Magento 2 module (Ecosire_EbayConnector) installed under app/code on your instance, version-pinned and Composer-installable

eBay developer app connection configured with your seller account via OAuth2 (sandbox validation then production cutover)

Attribute, category, and condition mapping configured for your actual catalog during onboarding

Admin configuration, listing grid, mapping screens, and sync dashboard with role-based ACL set up for your team

Cron jobs and message-queue consumers installed and verified for order import and async catalog sync

Deployment runbook plus a short admin guide covering listing, revising, and troubleshooting syncs

Post-launch support window with bug fixes and eBay API-change maintenance per the agreed plan

Who this is for

Multichannel eBay Seller

Runs an established eBay store alongside Magento and is tired of maintaining two inventories by hand. Needs stock and price to stay in lockstep so popular SKUs never oversell across channels.

Operations / Catalog Manager

Owns the Magento catalog and wants eBay listings generated from existing attributes and templates, with bulk list/revise/end actions instead of editing items one at a time in Seller Hub.

Magento Agency or In-House Developer

Wants a clean, ACL-gated module that follows Magento conventions (DI, plugins, observers, service contracts) so it can be code-reviewed, extended, and maintained rather than a black-box extension that breaks on upgrade.

Frequently Asked Questions about eBay Marketplace Connector

How long until the eBay connector is live on my store?

Typical delivery is 3 to 5 weeks from kickoff. The first week is scoping your catalog, attributes, eBay business policies, and a sandbox connection; the middle weeks are building and configuring the module on a staging copy of your Magento instance; the final phase is sandbox-to-production cutover and verification. Timeline shifts with catalog size and how much custom category/attribute mapping you need — we confirm a firm date after the scoping call.

Is this an instant download from the Adobe Commerce Marketplace?

No. This is a build-to-order extension. We build it specifically for your store, then install and configure it on your own Magento Open Source or Adobe Commerce instance. There is no instant Marketplace download — the $499 covers the build, installation, mapping setup, and onboarding.

What ongoing support and updates are included?

The engagement includes a post-launch support window for bug fixes and adjustments. eBay periodically changes its Sell APIs and policy requirements, so we offer ongoing maintenance plans that keep the connector compatible with eBay API versions and your Magento 2.4.x upgrades. You own the module code on your instance, so you can also have your own developers maintain it.

Does it work with Adobe Commerce as well as Magento Open Source?

Yes. The module targets Magento 2.4.x and works on both Magento Open Source and Adobe Commerce, including Adobe Commerce on cloud. It is multi-store and multi-website aware and respects Multi-Source Inventory (MSI) where you use it.

Will it overwrite my eBay listings or orders if something goes wrong?

No. All sync actions are queued, logged per action in a dedicated table with retry, and respect eBay rate limits. You control which SKUs sync via the admin grid, sandbox is validated before production cutover, and order import creates native Magento orders without altering existing ones. Failed actions surface in the dashboard rather than silently corrupting data.
