The Asos Marketplace Connector is a custom integration that ECOSIRE builds, installs and supports for your store — it is not an instant Shopify App Store download. After purchase, our team scopes your fashion catalog, builds the connector against your exact size curves and attribute taxonomy, and deploys it to your Shopify store.

The connector keeps your Shopify product catalog and the Asos marketplace in continuous sync. We map your Shopify products, variants and metafields to Asos's fashion taxonomy — brand, category, colour, size and material attributes — so listings meet Asos's strict content and image requirements before they go live. Stock and price changes propagate both ways: we read your multi-location inventory through the Shopify Admin GraphQL API and push adjusted availability to Asos, so you never oversell a size that just sold in-store.

On the order side, Asos orders are imported into Shopify as native orders with correct customer, line-item and tax data. Fulfilment and tracking sync back to Asos automatically, and returns flow back into Shopify so refunds and restocks stay accurate. We use Shopify webhooks (orders/create, inventory_levels/update, products/update) plus scheduled reconciliation jobs to keep both systems honest, with retry and conflict handling for the cases real catalogs hit.

Because it is built to order, the connector fits your actual SKU structure, size attribute mapping and bulk-listing workflow rather than forcing a generic template. You get a working integration installed on your store, documentation, and ongoing support from the team that built it. Typical delivery is a few weeks depending on catalog complexity and Asos onboarding status.
