Canada Post for OpenCart — rates, labels, tracking

Canada Post Shipping is a shipping module for OpenCart 4, 3 and 2.3: Canada Post rates at checkout for Canada, the US and other countries, a label from the order with the cost shown before you buy it, tracking and refund requests for labels you do not need. It works on your own keys, with no middleman.

Both account types work: Solutions for Small Business without a contract (the label is paid with the card in your Canada Post profile) and a commercial contract. English and French interface. Purolator is only in the WooCommerce version: its documentation sits behind a business account login; for OpenCart it will come in a separate release once we have access.

What the buyer sees

The buyer sees Canada Post services with the price and delivery time in the name: Regular Parcel, Expedited Parcel, Xpresspost and more. Prices are your contract prices or counter prices, with or without tax. If Canada Post does not answer, the fallback price is shown. For the US and other countries the module fills in the label customs data itself.

What the admin gets

The order page gets a Canada Post panel: weight, dimensions, province, phone. You see the label cost first, then buy the label; the PDF is kept in the shop. A Canada Post refusal is shown right in the label row as plain text. The buyer gets an e-mail with the tracking number in English or French.

The labels page lists every label with its status and filters: needs attention, on the way, delivered, refund requested.

How it works, step by step

1. You enter the API key, customer number and account type.
2. You pick the services, prices and a fallback price.
3. The buyer sees Canada Post rates at checkout.
4. On the order page you check the label cost and buy the label.
5. The buyer gets the tracking number by e-mail; the status refreshes in the panel.

Under the hood

• One shared library for OpenCart 4, 3 and 2.3.
• Requests go straight to Canada Post, not through our server.
• Keys are stored encrypted.
• Label PDFs are kept in the shop.
