The Freight API That Ships Real Freight

What is a freight API?

A freight API is a programmatic interface that lets your systems quote rates, book shipments, and receive tracking events without logging into a dashboard or calling a broker. Instead of copying rates from a website into your TMS, your code requests a rate, gets a JSON response, and books the load. Instead of waiting for email updates, your system receives webhook events the moment freight moves.

Developers need a freight API when manual freight workflows become a bottleneck. If your operations team is copying and pasting rates between systems, emailing carriers for tracking updates, or reconciling invoices by hand, a freight rate API eliminates that overhead. You connect once, and every quote, booking, and tracking event flows through your existing stack automatically.

A freight REST API makes freight programmable. The same way Stripe made payments programmable, a freight API makes quoting, booking, and tracking programmable. Your engineering team builds the integration once. Your operations team stops doing data entry.

What you can build with Warp's freight API

Quote freight rates programmatically. Send origin, destination, weight, and pallet count. Get back all inclusive rates across LTL, truckload, box truck, and cargo van in a single response. No fuel surcharges. No hidden accessorial fees. No terminal handling charges. The freight quote API returns the rate your customer will actually pay.

Book shipments from your own system. Once you have a rate, convert it to a booking with one call. Warp dispatches local 3rd party carriers through the Warp driver app. Your system gets a shipment ID and starts receiving tracking events immediately. No phone calls. No email chains. No broker in the middle slowing things down.

Receive tracking webhooks in real time. Every shipment on Warp generates scan events at the barcode and pallet level. Scan in at pickup. Scan out at delivery. GPS updates throughout transit. Proof of delivery photos and electronic signature capture. The freight tracking API pushes these events to your endpoint as they happen. Your TMS, ERP, or WMS stays current without polling.

Get POD data and scan history. Every pallet that moves through a Warp operated cross dock facility is scanned in and scanned out. The API returns the full scan trail for any shipment. For teams that need clean audit trails from pickup to delivery, this eliminates the document chase.

Integrate with any TMS, ERP, or WMS. Warp's freight API is designed to push data to your systems, not replace them. You keep your existing tools. Warp pushes scan events, GPS updates, delivery confirmations, and invoicing data to wherever your team already works.

Freight API vs freight broker

A traditional freight broker gives you a phone call. You call in, describe your load, wait for a quote, negotiate the rate, then wait again for tracking updates that come hours late. Your systems stay disconnected. Your team spends time on data entry instead of exceptions.

A freight API gives you control. Your code requests a rate and gets an answer in seconds. Your system books the load without human intervention. Tracking events push to your stack the moment they happen. You decide what triggers an alert, what flows into your dashboard, and what gets routed to your customer.

Warp is the infrastructure layer for freight. The same way Stripe gave developers a payment API so they could stop building payment processing, Warp gives developers a freight API so they can stop building freight operations. 20,000+ carriers. 9,000+ box trucks and cargo vans. 50+ Warp operated cross dock facilities. All accessible through a single freight REST API.

The difference is automation. With a broker, every load requires a conversation. With a freight API, every load is a function call. For teams moving hundreds or thousands of shipments per week, that difference compounds into days of recovered time and fewer errors across the operation.

How Warp's freight API works

Warp's freight API is REST based. You authenticate with API keys, send standard HTTP requests, and receive JSON responses. The API covers the full shipment lifecycle: rating, booking, tracking, and document retrieval. Every endpoint follows REST conventions, so your team can integrate using any language or framework that makes HTTP calls.

Rating requests accept origin, destination, commodity details, and shipment dimensions. The response returns all inclusive rates across available modes. LTL, truckload, box truck, cargo van. One request, multiple options. No separate calls per mode. No rate shopping across different carrier portals.

Webhook events are where the freight tracking API delivers the most value. When freight moves, Warp pushes events to your registered endpoint. Scan in at pickup. Departure from cross dock. GPS position updates during transit. Scan out at delivery. Proof of delivery with photos and electronic signatures. Your system processes these events however you need. Update your TMS. Notify your customer. Trigger an invoice. The data arrives in real time so you never have to poll for status.

Our AI backbone, Orbit, monitors every load moving through the network. Late pickups, route deviations, dwell anomalies, temperature deviations, missed scans. Orbit flags exceptions before your team has to chase them. Exception events are available through the API alongside standard tracking events, so your system can surface problems the moment they're detected.

Authentication uses API keys with scoped permissions. Rate limits are designed for production volume. Warp's freight API documentation covers authentication, request formats, response schemas, webhook payloads, and error handling. Your engineering team can go from reading docs to making live API calls in a single session.
