UPS add on 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 UPS 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 UPS rates for each vendor shipment
• ✓ Combines vendor charges into one checkout rate
• ✓ Works with vendor assignments from Toweringmedia Multi-Vendor Dropship

UPS REST API Integration

Offer Real-Time UPS Services and Pricing

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

Store administrators can select which UPS services should be available. Depending on the shipment and destination, supported services include UPS Ground, UPS Standard, UPS Next Day Air, UPS 2nd Day Air, UPS 3 Day Select, UPS Saver, worldwide services, and additional UPS delivery options.

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

Package Dimensions and Weight

Build UPS 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, Fees, Restrictions, and Checkout Availability

Configure the carrier from Stores > Configuration > Sales > Delivery Methods > UPS REST API (Toweringmedia) Multi-Vendor. Administrators can enable the method, change its checkout title, choose UPS services, apply handling fees, set weight limits, restrict destinations, and control its sort order.

• ✓ Fixed or percentage-based handling fees
• ✓ Shipping to all allowed countries or selected countries
• ✓ Configurable carrier title and checkout sort order
• ✓ Option to show the method when no applicable rate is available
• ✓ Vendor carrier and method settings managed under Toweringmedia Vendors

Performance and Diagnostics

Secure Rate Caching, Debug Rates, and Detailed 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.

Debug mode supplies realistic mock rates without contacting UPS, making it easier to verify the checkout experience during configuration. Rate calculations, API activity, warnings, and errors are recorded in var/log/tm_ups_multivendor.log.

• ✓ Five-minute rate-cache lifetime
• ✓ Vendor, destination, weight, method, and session-aware cache keys
• ✓ Input and cached-rate validation
• ✓ Mock shipping rates for development and testing
• ✓ Dedicated extension log file
