How Do I Setup a USPS Web Tool API?

A USPS shipping module can be integrated to any online business.

The United States Postal Service provides online businesses with a Web Tools API. API stands for application programming interface, and it can be integrated into a website that sells merchandise. The API functions with Zen Cart, which is an online shopping cart and checkout service. The interface automatically calculates shipping rates from the USPS for customer and seller convenience. A unique USPS Web Tools account and user ID is required for each Zen Cart business.

Instructions

1. Register for an account and Web Tools user ID (see Resources).

2. Wait 24-48 hours for the account to be verified and activated. An e-mail will be sent when the process has finished.

3. Log into Zen Cart. Navigate to "Admin" and then "Configuration." Click on "Shipping/Packaging." Enter the company's zip code into the "Postal Code" box.

4. Navigate to "Admin" and then "Modules." Click on "Shipping" and then "Install" under "USPS Shipping Module." The account is now set up in "Test" mode.

5. Call the USPS at 1-800-344-7779 to verify the set up and take it out of "Test" mode. It is now set to take orders.
