Troubleshooting WooCommerce Canada Post Plugin

In this tutorial, we will show you how to troubleshoot WooCommerce Canada Post Shipping Plugin with Print Label in case you are having trouble with getting real-time Canada Post Shipping Rates, print shipping labels and track your orders from your WooCommerce store. It is a complete guide to solving all the issues you face while using the plugin.

Troubleshooting for not Getting Rates at all

If you are not getting rates at all, then there might be some reasons for not fetching real-time shipping rates from Canada Post APIs. The list of reasons is as given below:

• Enable Shipping: That sounds a bit trivial. But sometimes we forget to select Enable shipping checkbox. By default, Enable Shipping is disabled. So this should be your first check. You must enable shipping at two places.
  1. You should select the checkbox at WooCommerce Settings as shown below:
  2. You should also select the checkbox at Canada Post Plugin Settings as shown below:

• Weight and Dimensions: Canada Post shipping carrier use the weight and the dimensions of your product (Length, Width & Height) to calculate the shipping cost (besides using the origin and destination address). So make sure that you enter the Weight and the Dimension of your product in Admin Product Settings as shown below:

If you have done the above basic checks and still not getting rates, then you must enable debug mode to get the exact reason for not getting rates.

Debug Mode

If you are not getting proper rates( lesser or higher than expected), not getting all the available shipping options, not getting rates at all, or not getting Print Labels, then you enable Debug option to find the error(s). You can also see the warning(s) by WooCommerce Canada Post Shipping plugin.

By enabling debug mode, you can trace issues using a log. You can see information about debugging at the top of the Cart and Checkout page. Select the Debug checkbox in Canada Post Plugin Settings to enable debug mode as shown below:

Note: To enable debug mode, first you need to enable Shipping Debug Mode by navigating   to WooCommerce > System Status as shown below:

After enabling debug mode, add a product to cart. Go to the checkout page to see the debugging information. Ensure that you have entered a proper shipping address. If you are not getting rates at all, then you need to check the response sent by Canada Post to know the exact reason for not showing the rates. Two cases are explained in the below section.

1. Shipping address Error: In case, the customer does not enter the correct postal code, then Canada Post does not display the rates. The customer is shown the message as shown below: To know the reason, you need to check the response sent by Canda Post as shown below: From the above response, you need to check the recipient, shipper address. So correct recipient address by clicking on Calculate Shipping in Cart/Checkout page as shown below:

You are shown the message as shown below: From this response, you can clearly make out that authorization is a problem. So you can enter the correct credentials in the Canada Post Settings page as shown below:
3. Weight Error: In Case, the weight of the product is not correct, then Canada Post does not display the rates. You are shown the message as shown below:

Troubleshooting for Correct Rates

The Request is sent to Canada Post by the plugin with a Zip code for the source, destination, and dimensions of the product. The sample Request to Canada Post is as shown below:

In the above request, the weight is in Kilogram. You can recheck the weight of the product by navigating to admin Product setting as shown below:

      2. Recheck Dimensions of the product with units. Product Dimensions gets converted to the centimeter and passed to Canada Post API. In the above request, the dimensions are in Centimeter.

Troubleshooting for Print Labels

If the selected service is not available for the particular location/product, you will get the error about service eligibility at the top of the page.To know details about the available services for required location/product contact Canada Post.
