The Amazon & eBay Multichannel Connector for WooCommerce turns your store into the control center for selling on Amazon (SP-API), eBay (Sell API), and Walmart Marketplace — without juggling three seller dashboards or exporting spreadsheets.

This is a build-to-order plugin: ECOSIRE builds it against your exact catalog, installs it on your live WordPress site, and supports it after launch. It is not an instant WordPress.org download. We scope your marketplace accounts, configure the OAuth credentials, map your categories and attributes, and hand you a working integration.

Under the hood the connector registers a custom WooCommerce settings screen in wp-admin, stores marketplace state in custom tables (HPOS-compatible — no overloading wp_postmeta), and runs sync jobs on a reliable WP-Cron schedule (or a real server cron if your host throttles WP-Cron). Product, inventory, and price changes flow through documented WordPress actions and filters so your developers can extend mappings without forking the plugin.

What it does for you: - Two-way product listing — push WooCommerce products (simple and variable) to Amazon, eBay, and Walmart, and pull marketplace-created listings back as draft products. - Real-time inventory & price sync — a stock change on any channel propagates everywhere, with per-channel buffer stock and price rules to prevent oversells. - Order import & fulfillment sync — marketplace orders land as native WooCommerce orders (HPOS custom order tables), and tracking numbers sync back to the marketplace. - Category & attribute mapping — map your WooCommerce taxonomies to each marketplace's required category tree and item specifics. - Bulk listing templates — reusable templates so you list hundreds of SKUs without re-entering data per product.

Every sync is logged with retry/backoff so a transient Amazon throttle or eBay API hiccup never silently drops an update. You keep one source of truth — WooCommerce — and ECOSIRE keeps the integration running.
