Fulfillment Hub by eKommissar

Fulfillment Hub helps Shopify resellers manage orders across multiple fulfillment partners using tag-based routing. Define routes that match product tags to each partner's HTTPS endpoint and API key. When customers pay, the app automatically forwards matching line items to the right vendors and logs all webhook activity for easy debugging. Perfect for split-order fulfillment—your partners can send shipment updates back through the Hub API so you can track progress across warehouses. Configure fulfillment routes, manage vendor API keys, and monitor order forwarding directly from your Shopify admin. Install once on your reseller store while each fulfillment partner runs their own app.
