Connect Canada Post

Join the Canada Post Developer Program, copy API username/password and customer number, then connect in Net3000.

Connect Canada Post so Storefront3000 can calculate live shipping rates at checkout.

In Net3000 admin, open Integrations → Canada Post (/apis/canadapost).

Sign in to Canada Post and join the Developer Program

Sign in (or create an account) at Canada Post, then open the Developer Program Getting Started page and click Join Now. Accept the program terms.
Copy your API keys and customer number

On the Developer Program page you will see API keys for development and production. Each key is a Username and Password pair. Also copy your Customer Number (shown on the same page / your business profile).

Use the production key for live checkout rates. Keep the development key for testing only.
Paste into Net3000

Open /apis/canadapost, enter Username, Password, and Customer Number, then click Save.
Verify rates at checkout

Place a test order in Storefront3000 and confirm live Canada Post rates appear during checkout.
