FedEx Addon for Multivendor Dropship

Multi-Vendor Rate Calculation

Calculate Shipping Accurately for Products Fulfilled by Different Vendors

A standard shipping calculation normally treats the cart as one shipment from one location. That approach can produce inaccurate charges when products are fulfilled by several vendors. This extension groups products using their assigned tm_vendor_id value and processes each vendor group independently.

For every vendor group, the extension uses the applicable vendor origin, selected FedEx services, package information, and destination address to request rates. The individual vendor charges are then added together and presented as one customer-friendly shipping method during checkout.

• ✓ Groups cart items according to their assigned vendor
• ✓ Uses a separate shipping origin for each vendor
• ✓ Requests FedEx rates for each vendor shipment
• ✓ Combines vendor charges into one checkout rate
• ✓ Works with vendor assignments from Toweringmedia Multi-Vendor Dropship

FedEx REST API Integration

Offer Real-Time FedEx Services and Pricing

The extension connects to the FedEx REST API using OAuth client credentials. It reuses the credentials and shared API settings configured in FedEx REST API (Toweringmedia) Standalone, keeping sensitive connection details in one central configuration.

Store administrators can select which FedEx services should be available. Returned services are filtered against both the carrier-level allowed-method setting and each vendor's configured FedEx service list. Administrators can also choose ACCOUNT rates for negotiated pricing or LIST rates for standard retail pricing.

• ✓ OAuth client ID and client secret authentication
• ✓ Automatic access-token handling
• ✓ Sandbox and production API support
• ✓ Administrator-controlled FedEx service selection
• ✓ Shared credentials with the Toweringmedia standalone FedEx carrier

Package Dimensions and Weight

Build FedEx Requests from Magento Product Data

Package dimensions can be obtained from the shared product attributes tm_pkg_length, tm_pkg_width, and tm_pkg_height. The extension supports product-attribute dimensions, automatically calculated dimensional weight, and a hybrid fallback mode.

When several items are included in one vendor shipment request, the package length and width use the largest item values. Package height is calculated by adding each item’s height multiplied by its quantity.

• ✓ Product-level length, width, and height attributes
• ✓ Product attributes, dimensional weight, or hybrid dimension modes
• ✓ Configurable minimum order weight
• ✓ Configurable maximum package weight

Flexible Administration

Control Services, Rate Types, Pickup Options, and Logging

Configure the carrier from Stores > Configuration > Sales > Delivery Methods > FedEx REST API (Toweringmedia) Multi-Vendor. Administrators can enable the method, change its checkout title, select FedEx services, choose negotiated or retail rates, configure the pickup type, and enable debug logging.

• ✓ ACCOUNT negotiated rates or LIST retail rates
• ✓ Configurable FedEx pickup type
• ✓ Configurable carrier title and allowed FedEx services
• ✓ Sandbox or production environment inherited from the base FedEx module
• ✓ Vendor carrier and method settings managed under Toweringmedia Vendors

Performance and Diagnostics

Secure Rate Caching and Detailed Debug Logs

Rate responses are temporarily cached to reduce repeated API requests. Cache entries distinguish the vendor, origin, destination, weight, allowed services, and customer session. Entries expire after five minutes, and automatic limits help prevent excessive cache growth.

When debug logging is enabled, vendor rate calculations and troubleshooting information are recorded in var/log/shipping.log. This helps administrators review vendor IDs, selected services, calculated prices, and API-related problems.

• ✓ Five-minute rate-cache lifetime
• ✓ Vendor, destination, weight, method, and session-aware cache keys
• ✓ Input and cached-rate validation
• ✓ Debug logging for vendor-specific calculations
• ✓ Logs written to Magento's shipping log
