Magento 2 FedEx REST API Shipping Extension

Connect Magento 2 directly to FedEx’s modern REST API platform and return real-time FedEx rates in cart and checkout. This extension uses OAuth2, supports sandbox and production credentials, and is designed for stable single-origin fulfillment quoting.

Short description

Real-time FedEx checkout rates via the official FedEx REST API + OAuth2.
Supports negotiated (ACCOUNT) rates and LIST rating from a single carrier configuration.
Controls for allowed methods, pickup type, top-N output, and optional transit-time display.
Volume-ready with shared package dimensions and dimension modes (product_attributes, auto_dim_weight, hybrid_fallback).
Admin tools for credential validation and sample-rate testing, plus optional debug logging.

How it works

Rates are calculated from your configured Magento Shipping Origin to the customer’s destination using total cart weight and resolved package dimensions. You control which FedEx services appear, how pickup type is set, and whether transit-time information is shown alongside rate options.

Merchant controls

Allowed FedEx services (offer only the methods that match your fulfillment strategy).
ACCOUNT vs LIST rating options from the same carrier configuration.
Pickup type configuration and optional transit-time display.
Top-N method output to keep checkout concise (optional).
Admin test tools for faster setup and troubleshooting.

Shared dimensions (suite-wide)

Keep one set of product dimensions across all Toweringmedia carriers using shared attributes:

tm_pkg_length
tm_pkg_width
tm_pkg_height

Dimension modes: product_attributes, auto_dim_weight, hybrid_fallback (recommended).

Works with the Toweringmedia Magento 2 Carrier Suite

For a consistent multi-carrier setup (shared dimensions, similar configuration patterns), pair FedEx with:

Need multi-origin (dropship / multi-warehouse) shipping?

This base FedEx module is intentionally single-origin for stability and predictable checkout behavior. If you ship from multiple vendor warehouses, extend your setup with:

Magento 2 Multi-Vendor Dropship Shipping System (UPS/USPS/FedEx Bundle)

Adds vendor-specific origins, per-origin carrier rating, and combined checkout totals while keeping the base carrier clean and reusable.

Which carrier should I enable?

Carrier	Best for	Strengths	Notes
UPS REST API	Domestic + negotiated pricing	Service control, negotiated rates, reliable quoting	Great “primary” carrier for many stores
USPS REST API	Lightweight parcels + cost-sensitive shipping	Caching, top-N output, fast common routes	Ideal complement to UPS/FedEx
FedEx REST API	Express + international service mix	Account vs list rating, pickup type, transit-time options	Strong for speed-focused delivery offerings

Who this extension is for

Stores that need real-time FedEx rates at checkout (not flat estimates).
Merchants who want ACCOUNT vs LIST rating options in one configuration.
Stores that want tighter control over allowed methods and delivery expectations.
Catalogs that require consistent dimensional-weight behavior across carriers.
Teams who want quick setup with built-in admin test tools.

FAQ

Can I use negotiated rates?
Yes — you can run negotiated (ACCOUNT) rates or list rating depending on your configuration.

Can I use this with UPS and USPS?
Yes — the carrier suite shares dimension attributes and consistent configuration patterns.

What if I ship from multiple warehouses/vendors?
Add the Multi-Vendor Dropship bundle for per-origin rating and combined totals.
