TMS API: Connect Your Transportation Management System to a Live Freight Network

What is a TMS API

A TMS API is an interface that connects your transportation management system to external freight networks, carriers, and data sources. Instead of manually entering tracking updates, delivery confirmations, and shipment status changes into your TMS, a TMS API automates that data flow. Your system receives updates as they happen, without anyone copying information from one screen to another.

Most transportation management systems were built as closed platforms. They manage your shipment records, but they rely on manual input or batch file imports to stay current. When a carrier picks up freight, someone has to update the TMS. When a delivery is completed, someone has to enter the proof of delivery. When an exception occurs, someone has to log it. A TMS API eliminates every one of those manual steps by pushing event data directly into your system in real time.

Warp's API connects your TMS to a live freight network of 20,000+ carriers, 9,000+ box trucks and cargo vans, and 50+ Warp operated cross dock facilities. When you book freight through Warp, every scan event, GPS update, and delivery confirmation flows back to your TMS automatically. Your transportation management system becomes a real time command center instead of a record keeping tool that is always a step behind.

How Warp integrates with your TMS

Warp pushes scan events, GPS updates, and delivery confirmations directly to your TMS via API. When a local 3rd party carrier picks up freight using the Warp driver app, a scan event fires and your TMS receives it. When the driver's GPS position updates, your TMS receives the location data. When freight arrives at a Warp operated cross dock facility, scan in and scan out events at the pallet level flow to your system. When delivery is completed, proof of delivery photos and electronic signature data are available through the API.

For line haul moves, ELD integrations on every truck provide continuous location data. This is not check calls at pickup and delivery. This is continuous visibility the entire way. Your TMS receives location updates throughout the transit, so your team and your customers can see exactly where freight is at any point in the journey.

Our AI backbone, Orbit, monitors every load in real time and flags exceptions before your team has to chase them. Late pickups, late departures, missed scans, route deviations, dwell anomalies, temperature deviations, and delivery exceptions are all detected automatically. These exception alerts are pushed to your TMS through the API, so your system can surface them to the right person at the right time. Your team gets the exception. Not the noise.

For enterprise programs, Warp works with your technical team to configure the integration and validate data flow before go live. Custom dashboards and alerts are available for teams that need visibility beyond what their TMS provides. The goal is to make Warp's freight network feel like a native extension of your transportation management system.

TMS API vs manual data entry

Manual data entry between your TMS and your freight carriers is the default for most shipping operations. A carrier picks up freight and your team updates the TMS. A delivery is completed and your team enters the proof of delivery. An exception occurs and your team logs it. Every one of these steps takes time, introduces errors, and creates delays between when something happens and when your system reflects it.

A TMS API integration eliminates that gap entirely. Every event that happens on a Warp shipment flows to your TMS automatically and in real time. There is no delay between a pickup scan at the dock and that scan appearing in your system. There is no delay between a delivery confirmation and your TMS showing the shipment as completed. Your data is always current because the data entry is automated.

The error reduction matters as much as the speed. Manual data entry leads to typos, missed updates, and inconsistent records. When your TMS relies on people to enter tracking data, the quality of your records depends on the consistency of your team. When your TMS receives data directly from the Warp API, every event is captured exactly as it happened. Scan timestamps, GPS coordinates, delivery photos, and electronic signatures are all recorded automatically with no room for transcription errors.

Which TMS platforms work with Warp

Warp's API uses standard REST conventions, which means any TMS that supports API integrations or webhook subscriptions can connect to Warp's freight network. The integration pushes scan events, GPS updates, and delivery confirmations from Warp to your system. Your TMS receives the data and maps it to your existing shipment records.

For teams running custom built transportation management systems, Warp's API documentation covers every available event type and data structure. Your development team can build the integration directly, mapping Warp events to your internal data model. Webhooks deliver events as standard HTTP POST requests, so no specialized middleware or connectors are required.

For enterprise customers with complex TMS environments, Warp provides dedicated integration support. A Warp rep works with your technical team to scope the integration, configure event subscriptions, map data fields, and validate the data flow in a staging environment before going live. This ensures that every event type your TMS needs is captured correctly and that the integration performs reliably at your shipment volume.
