To show Canada Post rates only when customers select shipping in our widget, we recommend integrating Canada Post in the Rates tab of Zapiet - Pickup + Delivery.
For any questions about the rate value, please contact Canada Post—we only show the rates they generate.
Integration steps will be slightly different, depending on the Zapiet - Pickup + Delivery rates version that you're using:
Requirements
All products that require shipping need to be marked as a Physical product in Shopify.
You will need to have an active account with Canada Post
You will need your Key number (username: password) from your Canada Post Developer Program account.
Log in to the Canada Post Developer Program website using the username and password for your Canada Post Solutions for Small Business account. Select your account number from the dropdown list.
On the Welcome page, copy the username and password that appear in the Production section of the API Keys table. These are included in the Key Number.
The Key Number includes two parts. The first part is your username, and the second part is your password (username: password).
