FedEx API Integration Services
We connect FedEx to the systems you already run: your storefront, WMS, OMS or ERP such as SYSPRO, Epicor Prophet 21 or NetSuite. Integrations are built on the FedEx REST APIs with OAuth 2.0, covering rate quotes, labels, tracking, address validation, pickups and FedEx Freight LTL, and they can sit inside a complete multi-carrier shipping platform we build for you.
Get Started- REST APIs + OAuth 2.0
- Rate Quotes
- Ship API Labels
- Track API
- Freight LTL
- SOAP Migration
What We Build
Rate Quotes
Request account-specific rates and transit times from the FedEx Rate API across Express, Ground, Home Delivery, Ground Economy and international services, so checkout and order entry show the shipping charges your account will actually be billed.
Ship API Labels
Create shipments and labels through the FedEx Ship API in PDF, PNG or ZPL, including multi-piece shipments, return labels, commercial invoices and electronic trade documents for international parcels.
Tracking
Pull scan events, estimated delivery and proof of delivery from the FedEx Track API, normalise the statuses, and push them to your order system and customer notifications.
SOAP Web Services Migration
FedEx has retired its legacy SOAP Web Services in favour of REST APIs. We move older integrations to the REST endpoints and OAuth 2.0 tokens, map the old request structures to the new ones, and verify results side by side before cutover.
FedEx Freight LTL
Integrate the Freight LTL API for palletised shipments: freight rate quotes, bills of lading, pickup requests and freight tracking, using your FedEx Freight account.
Address Validation and Pickups
Validate and classify addresses as residential or business before labels are created, and schedule or cancel courier pickups through the Pickup API.
How We Build Your Integration
Discovery
We map your order flow, the FedEx services and accounts you use, and where shipping data needs to land: storefront, WMS, OMS or ERP.
Architecture
We design token handling for OAuth 2.0 (tokens expire and must be refreshed), retry and timeout rules, rate caching, and how FedEx data maps to your order and shipment records.
Development
We build against the FedEx REST APIs with request validation, clear error mapping, and the connectors back into your ERP or order system.
Testing
We test in the FedEx sandbox with realistic scenarios: multi-piece, international with documents, returns and freight, then complete FedEx label certification where your integration requires it.
Launch and Support
We switch to production credentials, add monitoring and alerting on API errors and latency, and keep the integration current as FedEx versions its APIs.
Supported Platforms
We integrate with the platforms your business already uses, ensuring a smooth workflow from checkout to delivery.
Use Cases
ERP and Warehouse Shipping
Create FedEx labels from the pick-pack-ship step in your WMS, or directly 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 FedEx rates at checkout on Shopify, WooCommerce or a custom store, based on your account rates, package dimensions and destination.
B2B and Freight
Handle parcel and LTL from the same workflow: freight quotes, bills of lading and pickup requests for palletised orders alongside regular parcel shipments.
Multi-Carrier Shipping Platform
Run FedEx as one carrier inside a shipping platform that also connects UPS, DHL, Canada Post or Purolator, with rate shopping and business rules deciding the carrier per order.
Why Choose ZyroByte
Current FedEx APIs
REST endpoints, OAuth 2.0 client credentials and JSON payloads, built against the current FedEx developer documentation.
Connected to Your Systems
We connect FedEx to your ERP, WMS, OMS and storefront so shipping data flows without re-keying.
Label Certification Handled
We prepare label samples and take your integration through the FedEx label certification process where it is required.
Ongoing Maintenance
We track FedEx API versions and service changes and update your integration before they break it.
Secure Credentials
API keys and account numbers stored server-side and encrypted, with access tokens kept out of client code and logs.
Built for Volume
Queued label creation, rate caching and backoff on API errors so peak days do not stall fulfilment.
FedEx SOAP to REST Migration
FedEx has retired its legacy SOAP Web Services in favour of REST APIs. Integrations that still send SOAP requests, or rely on a plugin that does, need to move to the REST endpoints with OAuth 2.0 authentication. We inventory what the old integration does, rebuild it against the REST Rate, Ship, Track and Address Validation APIs, compare outputs against the old behaviour, and cut over with a rollback plan.
FedEx Ground Economy and Service Mapping
FedEx has renamed and retired services over the years (FedEx Ground Economy took its current name in 2023), and older integrations often still carry outdated service codes. We map every FedEx service your business uses, including Ground, Home Delivery, Ground Economy, Express and international options, to the correct REST service types so rates, labels and tracking stay consistent.
FedEx Integration for ERP and Order Systems
Most FedEx volume starts in an ERP or warehouse system, not a storefront. We connect FedEx to SYSPRO, Epicor Prophet 21, NetSuite and custom order systems so a shipment is created from the order, the label prints at the packing station, and the tracking number and shipping charges are written back automatically.
FedEx Inside a Multi-Carrier Platform
If FedEx is one of several carriers you use, we can build a complete shipping platform around it: a single interface for rate shopping, label creation, tracking and returns across FedEx, UPS, DHL, Canada Post and Purolator, with your own business rules for choosing the carrier.
