MailPlus API

The MailPlus API connects your own systems directly to MailPlus, so you can generate labels for MailPlus’ express service and track shipments without leaving your own software. It's the developer, code-level option — for businesses that want shipping built into their own systems, rather than managed through a separate platform.

It's end-to-end shipping software integration for 3PLs and businesses with warehouse or custom shipping systems. By connecting your systems straight to MailPlus, shipping happens automatically as orders flow through your own software — generate labels on demand, get live tracking visible in both your system and the MailPlus dashboard, and send automatic customer email notifications. Parcels move on the MailPlus network with 1–2 day express delivery Australia-wide.

The API is distinct from ShipMate. ShipMate is the platform you use directly — book pickups, print labels and track orders from one dashboard, with no code required. The API is for building that same shipping into your own systems instead. Same network, two ways to access it. Most businesses use ShipMate, our free platform — the API is for connecting your own systems at scale.

And you're not on your own once you're connected: API customers get full MailPlus team support — Sales, Customer Service & Retention, IT Systems, and direct contact with their local MailPlus Operator — plus team training on the shipping solution. Whether you connect through the API or use ShipMate on its own, MailPlus is a reliable, independent alternative to Australia Post and traditional couriers.
