Start using your USPS rates

Now that you have your USPS account connected, you will need to do the following to begin using your USPS rates for shipping quotes:

  1. Create shipping zones - Shipping zones allow you to have different service levels, rules, and shipping rates for different countries or groups of countries.
  2. Enable USPS service levels - Enabling service levels in the zones that you want to use them in allows you to offer different service levels to different zones.
  3. Test your shipping - Test your shipping to make sure everything is working properly and being displayed as intended before being used in production or going live on your website.
