How it works

Access the most up-to-date NMFC data—right from your own systems.

The ClassIT+ API connects directly to the official National Motor Freight Traffic Association, Inc. (NMFTA)™ classification database, delivering structured, real-time National Motor Freight Classification (NMFC®) data to your internal tools. Whether you're updating item classifications in your TMS, validating codes during quoting, or syncing changes across pricing engines, the API keeps everything current—automatically.

1. Connect

Secure your API key and integrate using standard REST endpoints. ClassIT+ provides sample code, developer support, and sandbox access for testing.

2. Sync

Your systems make calls to pull classification data like NMFC item numbers, descriptions, rule updates, and effective dates—whenever you need it.

3. Update

Automatically reflect NMFC changes (including replacements or cancellations) across your applications—no manual lookup or re-entry required.
