Install

No release zip yet. The repository archive installs, but the folder name will carry the branch suffix and updates will not flow:

wp plugin install https://github.com/scottjgd/wc-live-shipping-rates/archive/refs/heads/main.zip

Ships its own WordPress updater (built-in updater), so new versions show up under Dashboard → Updates.

Fetch live shipping rates from Canada Post, UPS, and Purolator at WooCommerce checkout.

Description

WC Live Shipping Rates is a WooCommerce shipping plugin that retrieves real-time rates from three major Canadian carriers and presents them as selectable options at checkout:

  • Canada Post — via the REST Rating API (v4)
  • UPS — via the UPS Rating API (OAuth 2.0)
  • Purolator — via the E-Ship Web Services SOAP API (v2)

Each carrier is a separate WooCommerce Shipping Method that can be added to any shipping zone. All three support:

  • Sandbox / test mode for development
  • Per-method rate markup (percentage)
  • Automatic unit conversion (weight & dimensions from your WooCommerce store settings)

Installation

  1. Upload the wc-live-shipping-rates folder to /wp-content/plugins/.
  2. Activate the plugin in Plugins → Installed Plugins.
  3. Go to WooCommerce → Settings → Shipping and click on a shipping zone (or create one).
  4. Click Add shipping method and add one or more of:
    • Canada Post (Live Rates)
    • UPS (Live Rates)
    • Purolator (Live Rates)
  5. Click the method name to expand its settings and enter your API credentials.

Carrier API Credentials

Canada Post

  1. Register at https://www.canadapost-postescanada.ca/information/app/drc/registered
  2. Create an application to get an API Username, API Password, and note your Customer Number.
  3. Start in Sandbox mode; switch to Production when ready.

UPS

  1. Register at https://developer.ups.com/
  2. Create an app to obtain a Client ID and Client Secret (OAuth 2.0).
  3. Your Shipper Account Number is the 6-character alphanumeric on your UPS invoice.
  4. Start in CIE (test) mode; switch to Production when ready.

Purolator

  1. Register at https://eship.purolator.com/ → Developer Tools → Register
  2. Create an application to get an API Key and API Password.
  3. Use your Purolator Account Number as the billing account.
  4. Start in Sandbox mode; switch to Production when ready.

Product Data Requirements

For accurate rates, ensure each product has:

  • Weight — set in WooCommerce product data → Shipping tab
  • Dimensions (Length × Width × Height) — same tab

If weight is missing, 0.5 kg is assumed. If dimensions are missing, a default box size is used.

Frequently Asked Questions

Rates are not showing at checkout

  • Enable WP_DEBUG in wp-config.php and check your PHP error log for [WCLSR] messages.
  • Confirm you are in the correct shipping zone (destination matches the zone).
  • Verify the destination postal code is filled in at checkout — rates require a postal code.

Can I add a handling fee?

Yes — each method has a Rate Markup (%) field. For example, enter 10 to add 10% on top of every carrier rate.

Does this support cross-border (US/Canada) shipments?

Canada Post and Purolator methods currently only query domestic Canadian rates. UPS uses a "Shop" (all-services) request and works for both domestic and international routes.

Does this support free shipping or flat-rate fallbacks?

This plugin only adds live carrier rates. Use WooCommerce's built-in Free Shipping and Flat Rate methods alongside it.
