Lazr’s Shipping API
Built for real-world shipping workflows
Fetch live multi-carrier rates in milliseconds
Skip manual carrier portals. Lazr returns real-time prices and service levels from FedEx, UPS, Purolator, DHL, Canada Post, Day & Ross, TST, Morneau and many others. All regional, national and international couriers with support for both your own tariffs and Lazr-negotiated contracts. Every rate response is optimized by Lazr’s engine, surfacing the cheapest, fastest, or best-value option depending on your rules, across parcels, pallets, cross-border, and time-definite services.
Access a growing network across North America and beyond, all through one unified, modern API.
Smart carrier selection templates
Automatically select the lowest-cost on-time option with our Pricing Intelligence, or steer decisions using carrier and supplier preferences that reflect how your business actually ships.
Auto-generate compliant labels & documents
With one call you receive the label, BOL, commercial invoice in PDF or ZPL, ready to print or inject into your WMS or OMS.
Bulk-rate and bulk-label operations
Process thousands of SKUs or orders in one call. Lazr’s asynchronous batch endpoints rate, book, and label high-volume shipments, ideal for peak season or 3PL workflows. Our platform will also soon feature webhook callbacks when completed. Stay tuned !
Handle global shipping with full landed-cost data
Lazr assembles all cross-border requirements: Harmonized codes, country-of-origin, tax identifiers (EORI, VAT, IOSS), USMCA/NAFTA documents, and commercial invoices. Let the platform auto-build commercial invoices to speed clearance.
Shipment statuses push straight to your order table—no polling—so customer care sees exceptions before customers do.
Validate & standardize addresses automatically
Eliminate delivery errors before they happen. Import and reuse saved ship-to/ship-from addresses to reduce keystrokes.
Practical applications
Batch-ship & eCommerce orders
Pass a CSV or array of SKUs; Lazr splits, rates, and books in a single transaction, then returns tracking numbers your storefront can surface immediately.
Omnichannel returns
Generate prepaid return labels on demand, complete with RMA codes, and feed them back to your portal in under a second.
Embedded shipping in SaaS
Build a “Ship Now” button inside your own application and let Lazr handle carrier complexity behind the scenes.
Practical applications
Just-in-time manufacturing
Auto-route pallet or parcel parts between plants; the API chooses the fastest lane while meeting your dock-time rules.
Cross-border compliance
Harmonized codes, NAFTA/USMCA docs, and commercial invoices are assembled automatically so your freight clears customs without extra brokerage emails.
