Carriers integration

Australia Post + ReturnMate

The default carrier for most Australian merchants. ReturnMate integrates with the MyPost Business API to generate branded return labels, pull live PAC rates, and validate customer shipping addresses before a label is ever issued.

§ 01 — Capabilities

What the integration does.

  • MyPost Business label creation (inbound + outbound)
  • Live PAC rate quoting at the customer portal
  • Address validation (street, suburb, state, postcode) pre-label
  • Tracking sync via MyPost Business API + webhook events
  • Branded labels with merchant logo
  • Dangerous goods detection and routing (AusPost is blocked for DG — see StarTrack)
§ 02 — Use cases

How merchants use it.

Customer-paid return shipping

At portal submission the customer sees a live AusPost quote for the cheapest service. If they accept, the shipping fee is charged via Shopify checkout and the label is generated only on payment.

Merchant-paid free returns

For faulty / warranty returns where the merchant covers shipping, the label is auto-generated on RMA approval with no customer payment step.

Address validation

Customer addresses are validated before the label is generated. AusPost's PAC API rejects invalid suburb/postcode combinations — we catch and suggest the valid version in the portal so labels aren't wasted.

§ 03 — Setup

Connect Australia Post in minutes.

  1. 1

    Add your MyPost Business credentials

    Settings → Carriers → Australia Post. Enter your MyPost Business account number and API key. ReturnMate encrypts both with AES-256-GCM.

  2. 2

    Configure service codes

    Pick which AusPost products to use for inbound returns (PR = parcel returns) and outbound replacements. Defaults are sensible for most merchants.

  3. 3

    Test label

    Generate a test label from Settings → Carriers to verify the credentials work end-to-end before going live.

§ 04 — FAQ

Questions about Australia Post.

Can Australia Post handle dangerous goods?

No. AusPost does not accept lithium batteries or most other ADG-classified goods. ReturnMate detects DG items and routes them to StarTrack (under 22kg) or TNT (over 22kg) automatically; AusPost is blocked for those shipments.

Is return-postage PAC pricing included?

Yes. The PAC (Parcel Avoider / Consumer) rate is queried live at portal submission so the customer sees the actual shipping cost before committing.

Do I get tracking events in real time?

AusPost pushes tracking events via webhook (when configured) and ReturnMate polls the tracking API every 30 minutes as a fallback. Both update the RMA timeline automatically.
