UniUni Shipping add-on for Cs-cart

Fast last-mile delivery across Canada and the US, managed from CS-Cart

UniUni is a fast-growing last-mile delivery network across Canada and the United States, well known for same-day and next-day parcel delivery in major metro areas. This add-on connects your CS-Cart store to UniUni so you and your vendors can book shipments, print labels, track parcels, and cancel orders straight from the admin panel.

Everything happens inside CS-Cart — no separate UniUni portal to sign in to and no manual copy-pasting of tracking numbers. Rates are negotiated directly with UniUni and are not shown at checkout; you charge customers using your usual CS-Cart shipping pricing. The add-on works standalone; paired with the CartModules: Advanced Shipping System foundation add-on you also get per-vendor credentials (Multi-Vendor editions only), multi-package weight and dimension aggregation, and centralized carrier status mapping across every installed carrier add-on.

Key Features

• Last-Mile Coverage — connects to UniUni for deliveries across Canada and the US
• Three Service Speeds — Standard, Same Day, and Next Day
• On-Demand Tracking — pull the latest status whenever you need it
• Cancellation With Refunds — cancel and have any prepaid amount refunded automatically
• Per-Vendor Accounts — each vendor can use their own UniUni access token

• Live & Test Modes — try things out before going live
• Works With or Without the Framework — standalone, or better with the Advanced Shipping System

Supported Services

You pick which speed a shipping method uses when you create it.

How It Works

1. Enter your UniUni access token in the shipping method settings
2. Create a CS-Cart shipping method that uses a UniUni service and set your customer-facing rates with normal CS-Cart pricing tools
3. A customer places an order and picks your UniUni-backed method at checkout
4. From the order page, you (or the vendor) create the shipment — the add-on sends details to UniUni and gets back a tracking number and a printable label
5. Download the label and hand the parcel to UniUni for pickup
6. Click Update Tracking any time to pull the latest info; the shipment status updates so customers always see the right information

Requirements

• CS-Cart Store Builder or Multi-Vendor (single or multiple storefronts) 4.6.3 or higher
• PHP 7.4 or higher (tested up to PHP 8.3)
• A UniUni account with an access token
• Recommended: CartModules: Smart Shipping & Fulfillment Manager (the per-vendor credentials feature requires CS-Cart Multi-Vendor)

Installation

1. Go to Add-ons > Manage add-ons, click Manual installation, and upload the addon zip file
2. Activate the addon and enter the license key
3. (Recommended) install CartModules: Smart Shipping & Fulfillment Manager first, then go to Shipping & Taxes > Shipping methods, add a method, pick UniUni and a service, and enter your UniUni access token (see Configuration)

Configuration Options

Rates are negotiated directly with UniUni and are not shown at checkout — charge customers using flat, weight-based, or table rates. In Multi-Vendor with per-vendor credentials enabled, each vendor’s own access token is used for their shipments. Available actions: Purchase Shipment, Download Label, Update Tracking, Cancel Shipment (refunds any prepaid amount).
