Automate what you already do in your panel. Instead of manually entering orders, printing labels, and checking tracking, let your system do it automatically.

## Getting started

Ask your 4N NextDay administrator for an API token (tokens are issued per merchant account from the admin panel — there is no login step), then connect your system. Once connected, your orders sync automatically, labels print on demand, and tracking updates flow to your customers in real-time.
