Get your Australia Post API credentials
To connect your account, you will need three credentials from Australia Post: your account number, API key, and API password.
- Log in to the Australia Post Developer Center.
- If you don't have a developer account, click Register and create one using your business email address.
- Once logged in, navigate to My Apps and create a new application.
- Give the application a name (e.g., "Zonos Integration").
- Select the Shipping and Tracking API.
- Submit the application.
- After your application is approved, open it from My Apps to view your credentials:
- API key — listed as the application key
- API password — listed as the application password
- Your account number is your existing Australia Post business account number, found in your Australia Post business account or on any invoice from Australia Post.
Note: API credential approval may take 1–2 business days. Contact your Australia Post account representative if you need assistance.
Connect your Australia Post account to Zonos
- Go to Zonos Dashboard -> Settings -> Manage rates.
- Click Add carrier.
- Select Australia Post.
- Enter your credentials:
- Account number
- API key
- API password
- Click Save to finish.
Tip: If you don't have API credentials yet, you can add Australia Post without credentials to set up flat rates manually. Click Continue without credentials on the connection screen, then add a rate sheet after connecting.
Start using your Australia Post rates
Now that your Australia Post account is connected, complete the following to begin using live rates:
- Create shipping zones — Shipping zones let you configure different service levels, rules, and rates for different countries or groups of countries.
- Enable Australia Post service levels — Enable the service levels you want to offer in each shipping zone.
- Test your shipping — Verify that rates are returning correctly before going live.
For accurate quotes: Item weights must be set for each product in your shopping cart platform. If items or boxes exceed 11" on any side, dimensional weight pricing may apply.
Create labels and generate your manifest
Australia Post requires every shipment to be lodged as part of an order. In Zonos, you build that order by adding your Australia Post labels to a group, then closing the group to create the order and generate your Order Summary — the manifest you print and present to Australia Post at lodgement.
Adding shipments to a group
When you create a label for an Australia Post shipment, a dialog appears prompting you to add the shipment to an existing group or create a new one.
After you select or create a group, the shipment is added to it and your label is created. Build the group as you create labels throughout the day — typically one group per lodgement (for example, one per day).
Managing your groups
To see your groups, go to Zonos Dashboard -> Shipping -> Manifests in the left-hand menu.
From here you can view each group, the number of shipments in it, and its status. Click a group to see the shipments it contains.
Closing a group to create your order and manifest
When you are ready to ship, open the group and click Close group (you can also close it from the list view). Closing the group creates the order with Australia Post and generates your Order Summary.
Once the group is closed, a Download manifest button appears. Download and print the Order Summary, then present it with your parcels at lodgement. You can re-download it any time from the same screen.
Note: Closing a group is final. Australia Post creates the order from the shipments in the group at that moment, so make sure every parcel you intend to lodge has been added before you close.
Voiding a label
Void an Australia Post label before its group is closed. Once the group is closed and the order has been created, the shipment is part of an Australia Post order and can no longer be voided — create a new shipment instead.
Australia Post account connection
