OTTO Marketplace Integration for WooCommerce is a build-to-order plugin that bridges your existing WooCommerce store with the OTTO marketplace (otto.de) — Germany's second-largest online marketplace. It is not an instant download from WordPress.org or WooCommerce.com. Instead, ECOSIRE engineers build the connector against your OTTO Partner API credentials and your catalog structure, then install and configure it directly on your WordPress site, with ongoing support afterwards.

Once live, the plugin pushes your WooCommerce products as OTTO offers, keeping stock quantities and prices in continuous sync so you never oversell across channels. It imports OTTO orders into WooCommerce as native orders (fully HPOS / custom-order-tables compatible), and writes shipment, tracking and cancellation updates back to OTTO to keep your seller metrics healthy.

Because every OTTO catalog is category- and attribute-specific, we map your WooCommerce product attributes, variations and taxonomies to the correct OTTO product categories and required attributes — including brand, EAN/GTIN, and delivery-time fields. Sync runs on WP-Cron (or a real server cron for high-volume stores), with a wp-admin settings screen for credentials, mapping rules, batch size and logging.

The build respects your stack: it hooks into WooCommerce via WordPress actions and filters (woocommerce_update_product, woocommerce_reduce_order_stock, custom REST endpoints), supports WPML/multilingual German catalogs, and is multisite-aware where needed. You receive clean, documented code on your server — no third-party SaaS middleman holding your data.

Delivery is honest: a typical build ships in one working week after we receive your OTTO API access, with a fixed one-time price and a support window for fixes and OTTO API changes.
