The Australia Post & AU Carriers Connector is a custom Shopify app built to order for Australian merchants who need accurate, local carrier rates and real label workflows — not generic flat rates or a one-size-fits-all App Store plugin.

ECOSIRE builds, installs and configures this app directly into your Shopify store. It connects to the Australia Post Shipping & Tracking API (eParcel/MyPost Business), Sendle, Aramex AU and CouriersPlease using your own carrier accounts and API credentials, so the rates your customers see at checkout reflect your negotiated pricing.

At checkout, the app returns live, calculated rates via Shopify's Carrier Service API based on cart weight, dimensions, destination postcode and your packaging rules. After an order is placed, your team generates eParcel and carrier labels in bulk, prints manifests, and books pickups — all from within Shopify Admin. Fulfilment and tracking numbers are pushed back through the Admin GraphQL API, and tracking status syncs keep order timelines and customer notifications current.

Because it's built for your store, we wire it to your setup: multi-location inventory for rate origins, metafields for per-product dimensions and dangerous-goods flags, and webhooks (orders/create, fulfillments/create) so automation fires reliably. International and domestic routing rules let you steer parcels to the right carrier by weight, value or zone.

This is an honest build-to-order engagement: you purchase, we scope your carriers and rules, then build, install via OAuth, test against your real catalog, and hand over a working integration with documentation. No instant download — a real, supported app tailored to your AU logistics.
