Connect Your System to 4N NextDay
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.
