• How do I set up the USPS shipping module?

    In order to use the USPS module, you need to have a USPS WebTools account, signed up to use their Rate Calculator API.
    1. If you have an account with USPS for using shipping assistance this is not the same as the WebTools user ID needed for the shopping cart.
    2. You must have a separate WebTools user ID for each web store.
    3. Here is the link for registering. https://secure.shippingapis.com/registration/
    4. You will soon (24-48 government hours) receive e-mail from USPS with your user ID and some generic instructions.
    5. In your Zen Cart admin area, make sure you have a zip code entered at: Admin|Configuration|Shipping/Packaging|Postal Code
    6. In your Zen Cart admin area, go to Admin|Modules|Shipping, and click on the USPS shipping module, click Install, and fill out the various configuration information fields.
    7. Call USPS 1-800-344-7779 (7:00AM to 11:00PM ET) and ask them to take account out of Test...ie: Put into production mode.
    8. (If your module doesn't generate quotes properly after this, call USPS back and make sure they have enabled the RateCalculator on your account profile.)
