LTL Freight API: One Integration, Every LTL Lane

What is an LTL freight API?

An LTL freight API is a programmatic interface that lets developers and logistics teams quote, book, and track less than truckload shipments without logging into a portal or calling a broker. Your platform sends a request with origin, destination, and cargo details. The API returns rates, accepts bookings, and pushes tracking events back to your system in real time.

For teams building LTL into a TMS, marketplace, ERP, or customer facing shipping tool, an LTL API eliminates the manual steps that slow down quoting and booking. Instead of copying rates from a carrier website or waiting on email confirmations, your system handles the entire workflow programmatically. Every quote pulls from a live carrier network. Every booking triggers dispatch. Every milestone pushes back to your system automatically.

Most LTL APIs aggregate rates from traditional carriers and pass them through. Warp's LTL API is different. It connects directly to Warp's own operating network of 50+ cross dock facilities and 1,400+ active lanes. The rates come from Warp's freight movement, not a rate aggregator reselling someone else's capacity.

How Warp's LTL API works

Quote by origin ZIP, destination ZIP, and pallet count. Warp's API returns an instant all inclusive rate covering pickup, cross dock handling, line haul, and delivery. No fuel surcharges. No accessorial fees. No terminal handling charges. The rate you receive is the rate you pay.

Book programmatically with a single API call. Once you accept a rate, the booking triggers dispatch through Warp's carrier network. Local 3rd party carriers operating through the Warp driver app handle pickup and delivery. For line haul legs, ELD integrations provide continuous location data between facilities.

Receive tracking events as they happen. Scan in at pickup. Scan out at the origin cross dock. Line haul departure and GPS position updates. Scan in at the destination cross dock. Scan out for final delivery. Proof of delivery with photos and electronic signature. Every event pushes to your system via webhooks so your platform stays current without polling.

For teams building an aggregated LTL freight API, Warp functions as a single integration point covering 1,400+ lanes across 12 markets. One connection gives you programmatic access to the entire Warp LTL network instead of integrating with multiple traditional LTL carriers individually.

LTL API vs traditional LTL quoting

Traditional LTL quoting means calling a broker, emailing rate requests, or logging into multiple carrier portals. You wait hours or days for a response. When the rate comes back, it's a base rate plus fuel surcharges, accessorial fees, and terminal handling charges that change the final cost. If you want to compare across carriers, you repeat the process for each one.

An LTL API returns instant rates programmatically. Your system sends a request and gets a price back in seconds. With Warp, that price is all inclusive. Pickup, cross dock handling, line haul, delivery. No fuel surcharges added after the fact. No accessorial surprises on the invoice. The rate in the API response is the rate on the bill.

Visibility works the same way. Traditional LTL tracking means check calls. You call the carrier or broker, ask where the freight is, and hope someone answers. Warp's LTL API pushes scan events and GPS updates to your system automatically. Scan in at pickup, scan out at each cross dock, line haul GPS, delivery confirmation with proof of delivery. Our AI backbone, Orbit, monitors every shipment and flags exceptions like late departures, missed scans, and dwell anomalies before your team has to chase them.

LTL through Warp cross docks

Every LTL shipment on Warp moves through the Warp cross dock network. This is not a traditional LTL terminal system where freight sits for days waiting for enough volume to fill a trailer. Warp's 50+ facilities are designed for flow. Freight arrives, gets sorted at the pallet level, and moves out.

The movement is a two touch model. A local carrier picks up from the shipper and delivers to the origin cross dock. Freight is scanned in, sorted, and loaded onto a line haul truck to the destination cross dock. At the destination facility, freight is scanned in again, sorted for final delivery, and a local carrier handles the last mile. Every pallet is scanned at every touch point.

Our AI backbone, Orbit, monitors the entire process. Dwell time at each facility. Line haul departure times. Scan completeness. If a pallet is scanned into a cross dock but not scanned out within the expected window, Orbit flags it. If a line haul truck departs late or deviates from the expected route, Orbit flags it. Your team gets the exception alerts through the API. Not the noise.

For local LTL within a metro area, Warp can operate dockless. Freight goes directly from pickup to delivery on shared vehicles without a cross dock stop. This depends on the SLA and route density. Whether cross dock routed or dockless, every shipment gets the same scan events, GPS tracking, and Orbit monitoring through the API.
