The Etsy Marketplace Connector is a build-to-order Magento 2 / Adobe Commerce extension that turns your store into the single source of truth for an Etsy shop. It is not an instant Marketplace download — ECOSIRE engineers it against your catalog, attribute set, and Etsy shop configuration, then installs and supports it.

Delivered as a proper module under app/code/Ecosire/EtsyConnector, it follows Magento conventions end to end: service contracts (API interfaces) for listing, inventory, and order sync; di.xml preferences and plugins instead of core rewrites; observers on sales_order_save_after and cataloginventory_stock_item_save_after; and cron groups for scheduled reconciliation. All Etsy traffic goes through the official Etsy Open API v3 with OAuth 2.0, rate-limit handling, and retry/backoff.

Real-time price and stock changes in Magento push to Etsy via queued consumers (Magento message queue / RabbitMQ on Adobe Commerce, or DB-backed cron queue on Open Source). Etsy orders import as native Magento orders, with SKU and variation matching against your configurable products. Attribute and variation mapping is handled in a dedicated admin grid (UI components + acl.xml-protected menu), so your Magento attributes resolve to Etsy's taxonomy and property model. Bulk listing tools let you publish and update many products in one batched, logged operation.

Everything is admin-configurable (system.xml / config), logs to its own channel for auditability, and exposes REST and GraphQL endpoints so your own tooling can trigger or read sync state. You own the code after delivery. ECOSIRE handles installation on your environment and provides ongoing support and compatibility updates.
