UPS API Integration Services
We connect UPS to your storefront, WMS, OMS or ERP such as SYSPRO, Epicor Prophet 21 or NetSuite. Integrations use the UPS REST APIs with OAuth 2.0 for rating, shipping, tracking, address validation, pickups and paperless invoices, and can run on their own or as one carrier in a multi-carrier shipping platform we build for you.

What We Build
Rating and Time in Transit
Request negotiated account rates from the UPS Rating API across Ground, 3 Day Select, 2nd Day Air, Next Day Air, Ground Saver and international services, and combine them with transit time estimates for checkout or order entry.
Shipping API Labels
Create shipments and labels through the UPS Shipping API in GIF, PNG, ZPL or EPL, including multi-package shipments, return services and international documents.
Tracking
Pull tracking activity from the UPS Tracking API, or subscribe to tracking events where your account supports it, and push normalised statuses to your order system and customers.
Address Validation
Validate and classify addresses as residential or commercial before labels are created, which avoids address correction charges and failed deliveries.
Paperless Invoice
Upload commercial invoices and other trade documents electronically through the UPS Paperless Documents API so international shipments move without printed paperwork.
Pickups
Request, check and cancel UPS pickups through the Pickup API, tied to the shipments created that day.
How We Build Your Integration
Discovery
We map your order flow, UPS account setup and service mix, and where shipment data needs to go: storefront, WMS, OMS or ERP.
Architecture
We design OAuth 2.0 token handling with client ID and secret, error and retry rules, rate caching, and the data mapping between UPS and your order records.
Development
We build against the UPS REST APIs with request validation, readable error mapping and the connectors back into your systems.
Testing
We test in the UPS customer integration environment with domestic, multi-package, international and return scenarios before switching to production.
Launch and Support
We go live with monitoring on errors and latency, and keep the integration current as UPS versions its APIs and services.
Supported Platforms
We integrate with the platforms your business already uses, ensuring a smooth workflow from checkout to delivery.
Use Cases
Warehouse and ERP Shipping
Create UPS labels at the packing station from your WMS, or straight from sales orders in SYSPRO, Epicor Prophet 21 or NetSuite, and write tracking numbers and shipping charges back to the order.
Storefront Checkout Rates
Show live UPS rates at checkout on Shopify, WooCommerce or a custom store, calculated from your account rates, package dimensions and destination.
International Shipping
Generate commercial invoices, upload them with Paperless Invoice, and track cross-border shipments through customs from the same workflow as domestic orders.
Multi-Carrier Shipping Platform
Run UPS as one carrier inside a shipping platform that also connects FedEx, DHL, Canada Post or Purolator, with rate shopping and rules choosing the carrier per order.
Why Choose ZyroByte
Current UPS APIs
OAuth 2.0 and REST throughout. UPS retired access-key authentication, and we migrate older integrations that still depend on it.
Connected to Your Systems
UPS wired into your ERP, WMS, OMS and storefront so shipping data flows without re-keying.
Production Reliability
Timeouts, retries with backoff and fallback behaviour so a slow UPS response does not stop your warehouse.
Ongoing Maintenance
We follow UPS API version and service changes and update the integration ahead of them.
Secure Credentials
Client secrets stored encrypted server-side, with access tokens kept out of client code and logs.
Built for Volume
Queued label creation, rate caching and batch processing for peak season.
UPS OAuth 2.0 Migration
UPS no longer accepts the old access-key authentication; every API call now needs an OAuth 2.0 bearer token obtained with a client ID and secret. Integrations and plugins built on access keys stop working until they are migrated. We move them to OAuth, update request formats to the current REST APIs, and test against your real shipping scenarios before cutover.
UPS Rating API Integration
The UPS Rating API returns rates for a single service or all available services for a shipment. We build rate calculation that accounts for package dimensions, dimensional weight, residential surcharges, negotiated account rates and multi-package shipments, with caching so checkout stays fast without calling UPS on every page view.
UPS Integration for ERP and Warehouses
We connect UPS to SYSPRO, Epicor Prophet 21, NetSuite and custom order systems so shipments are created from orders, labels print on thermal printers in ZPL or EPL, and tracking numbers and shipping charges return to the ERP without manual entry.
UPS Label Generation and Service Mapping
We automate label creation for single and multi-package shipments, returns and international documents, and keep service mappings current, including UPS Ground Saver, the service previously known as UPS SurePost.
