API

The Track123 REST API allows you to integrate shipment tracking directly into your own systems — order management platforms, fulfillment systems, or customer-facing products.

Authentication

All API requests require your API token in the Authorization header:

Authorization: Bearer YOUR_API_TOKEN

Your token is available on the Home page under the For developer panel. Click Reset to invalidate and regenerate it at any time.

Warning: Never expose your API token in client-side code or public repositories.
