Build 3PL software on the Warp freight API.
Stop building carrier integrations one at a time. One API gives your 3PL software quoting, booking, tracking, invoicing, and documents across 20,000+ carriers. Sandbox keys are free with no card. Production keys ship with all-inclusive per-pallet pricing — no broker margin layered on, no per-call fees, no enterprise contract gating. White-label by default; your clients never see Warp.
No card to evaluate · No sales call · No broker margin · White-label by default
Why 3PL operators build instead of buy
Every 3PL has unique workflows, client requirements, and margin structures. Off-the-shelf platforms force you into their data model, their UI, and their limitations. You end up building workarounds for every client exception. Custom software lets you control how clients submit orders, how rates are presented, how tracking is displayed, how invoices are structured. The hard part has always been freight execution — carrier onboarding, rate negotiation, EDI integrations, tracking normalization, document management. Warp is that layer, exposed as one API.
- -Off-the-shelf 3PL platforms force rigid workflows that don't match your operations.
- -Every client has different requirements: rate structures, reporting formats, pickup instructions, billing cycles.
- -Building custom software gives you control. The carrier integration layer is the bottleneck.
- -Warp's API eliminates that layer so your team focuses on the client experience.
What Warp's API replaces in your stack
Carrier connectivity, rate management, dispatch, tracking normalization, invoice processing — replaced by structured API calls.
4-week migration playbook
The shape of every 3PL-Tech migration we see: one week to map and prototype, one week shadow-running quotes, one week cutting over booking and tracking per-client, one week reconciling invoicing and decommissioning the old integration. No big-bang switchover, no production risk in week one.
Week 1
Endpoint mapping + quote dry-run
Sign up at /agents/account and map every endpoint your existing 3PL software calls today (quote, book, track, document) to the Warp equivalent. Quote endpoints are free, so you can call them as much as you need to validate schemas. Identify gaps before booking any real freight.
Week 2
Quoting in your portal
Wire POST /api/v1/freight/quote into your client-facing portal alongside the existing carrier API. Run both in shadow mode for a week — quote with both, log the spread, but only present the existing carrier's rate to your client. Confirm the Warp rate is competitive on the lanes you care about.
Week 3
Booking + tracking cutover
Move quoting traffic to Warp on a per-client allowlist. Wire booking and tracking. Validate live shipments end-to-end with one or two pilot clients. Use webhooks for status updates so your portal pushes updates to your clients in real time. Switch over per-client as confidence builds.
Week 4
Invoicing + decommission
Cut over invoice and document workflows. Reconcile a billing cycle to confirm line items match. Decommission the gated carrier API integration. Move to the Operator tier for volume discounts and Net 30 once monthly shipments cross the threshold.
Vs. gated carrier APIs
Every other top-ten U.S. freight network gates their shipper API behind a sales call, an enterprise contract, or both. None publish per-shipment pricing. Most layer broker margin into the quotes they return. The structural difference matters most for 3PL-Tech operators who need to evaluate, integrate, and ship clients fast.
Build a branded client portal
Your clients log into your portal, see their shipments, get quotes, and book freight. All powered by Warp's API underneath. Your clients never see Warp. They see your brand, your UI, your communication.
Client logs in
Your portal authenticates the client. Your system maps the client to their rate card and preferences.
Client requests a quote
Your portal calls POST /api/v1/freight/quote with the client's origin, destination, pallet count, and weight. Warp returns rates in structured JSON. You apply margin and display.
Client books a shipment
Your portal calls POST /api/v1/freight/book with the selected quote. Warp returns a tracking number and shipment ID. You store it in your database.
Client tracks their freight
Your portal calls GET /api/v1/freight/track/{shipmentId}. Warp returns structured status. You display it in your branded UI.
Client downloads documents
Approved accounts can add BOL, POD, and settlement document workflows. You serve those documents through your branded interface.
Example: Quote on behalf of a client
curl -X POST https://www.wearewarp.com/api/v1/freight/quote \
-H "Content-Type: application/json" \
-H "Authorization: Bearer wak_live_YOUR_KEY" \
-d '{

}]
}Your software receives this JSON, applies your margin (say 18%), and presents $808.30 to your client. The client sees your rate. Warp sees your API call.
Multi-client architecture
Your 3PL software serves multiple clients. Each client has different rate cards, pickup locations, delivery preferences, and billing cycles. Warp's API lets you quote and book on behalf of each client with their specific configuration.
Client isolation
Each client sees only their shipments.
Your system maps each client to their own context. When you call the tracking or shipments endpoint, you filter by the shipment IDs belonging to that client. Warp returns structured data. Your software controls who sees what.
Rate card management
Custom rates per client.
On the Operator tier, work with a Warp rep to build client-specific rate cards for recurring volume. Your software calls the quote endpoint and applies your margin before presenting rates. Each client can have different margin structures.
Billing and invoicing
Invoice data per shipment.
Approved invoice data workflow returns structured line items and totals. Your software aggregates invoices per client, applies your markup, and generates client-facing invoices on your billing cycle. Net 30 available on Operator tier.
Where 3PL-Tech wins on Warp
The Operator tier is built for this audience. Pricing scales with shipment volume, lane locks protect recurring patterns, and Net 30 makes the working-capital math work.
Volume tier
Operator pricing
Per-pallet discounts that increase as monthly shipment count rises. No seat licenses, no API call fees. See published ranges at /api-pricing.
Lane locks
Predictable margin
Lock per-pallet pricing on recurring lanes for a defined window. Your client-facing rate can hold for the full quarter while your floor stays predictable.
Bulk-rate API
Quote 200 lanes at once
Batch-quote any lane × mode combination programmatically. Useful for RFP responses, client onboarding, and freight benchmarking dashboards.
Net 30
Working-capital fit
Qualifying volume unlocks Net 30 invoicing. Your collection cycle from clients runs ahead of your payment cycle to Warp.
White-label
Your brand, every surface
Your clients never see Warp. Tracking pages, BOLs, invoices, and email confirmations all carry your brand. Warp is the layer underneath.
Dedicated success
Network tier, when you outgrow Operator
Custom contracts, locked lane cards, dedicated success manager, and white-label embedding for TMS partners. The path when one of your clients turns into a $10M+/year freight relationship.
The freight network underneath
When your 3PL software calls Warp's API, it connects to a freight execution network built on local third-party carriers dispatched through the Warp driver app. Every shipment gets live GPS tracking, scan-in/scan-out events, proof of delivery photos, and electronic signature capture. Our AI backbone, Orbit, monitors every load for late pickups, missed scans, route deviations, and delivery exceptions before your team has to chase them.
20,000+ carriers
Local third-party carriers on the Warp driver app.
Cargo vans, 26 ft box trucks, and 53 ft dry vans. All dispatched through the Warp driver app with live GPS, scan events, and proof of delivery.
50+ cross docks
Warp-operated facilities for LTL consolidation.
Every pallet scanned in and scanned out. Cross docking, sortation, and transloading. Your API calls route freight through the nearest facility automatically.
Orbit monitoring
Our AI backbone, Orbit, watches every load.
Automated quality monitoring flags late pickups, late departures, missed scans, route deviations, dwell anomalies, and delivery exceptions before your team has to chase them.
Frequently asked questions
How does white-label work in a multi-tenant 3PL TMS built on the Warp API?
Warp returns structured JSON from API calls — no Warp UI ever touches your clients. Your engineering team maps each client to their own context, applies per-client rate cards and margins, and renders quoting, booking, tracking, and invoicing inside the TMS your team owns. If you want a pre-built portal or widget instead of building the UI yourself, see /3pl-platform.
How does client isolation work when I manage multiple shippers?
Every API call can include client specific parameters. You quote and book on behalf of each client with their rate cards, preferences, and billing. Your system controls which client sees which shipments, rates, and documents. Warp returns structured data that your software routes to the right client context.
Can I set custom rate cards for different clients?
Yes. On the Operator and Network tiers, work with a Warp rep to build client-specific rate cards for recurring volume. Your 3PL software calls the quote endpoint and receives rates based on the rate card tied to your account. You apply your own margin on top before presenting rates to your clients.
How long does it take to migrate from a gated carrier API like C.H. Robinson?
A typical migration is four weeks of part-time engineering work: one week to map endpoints and exercise the free quote endpoints, one week to wire quoting into your existing portal, one week to migrate booking and tracking, and one week to cut over invoicing and document workflows. Quote endpoints are free, so you can prototype the full read-side before adding a card or talking to anyone at Warp.
What freight modes does the API support?
The Warp API supports LTL, FTL, 26 ft box truck, and cargo van. You can specify a vehicle type or omit it and let Warp auto select the right asset based on item dimensions and weight. Multi stop FTL is also supported for complex routing.
Do I need to build carrier integrations myself?
No. That is the entire point. Warp connects you to 20,000+ carriers, 50+ cross dock facilities, and 9,000+ box trucks and cargo vans through a single API. One integration replaces dozens of carrier connections, rate negotiations, and tracking normalizations.
What pricing tier should a 3PL operator pick?
Most 3PL-Tech companies start on the Builder tier (pay-as-you-go) to prototype, then move to the Operator tier once they have recurring volume. Operator pricing includes volume discounts, lane-rate locks for repeating shipping patterns, bulk-rate API for batch quoting, and Net 30 invoicing on qualifying volume. See /api-pricing for the full breakdown.
