1. Obtaining Your USPS API Credentials

Before you can integrate the USPS API, you’ll need to obtain your API credentials (User ID). Here’s how:

1. Visit the USPS Web Tools Registration Page: Navigate to the official USPS Web Tools registration page. You can usually find it by searching “USPS Web Tools Registration” on Google.

2. Fill Out the Registration Form: Provide all the required information accurately. This typically includes your name, address, email address, and website URL.

3. Accept the Terms and Conditions: Carefully read and agree to the USPS Web Tools terms and conditions.

4. Submit Your Application: Submit the registration form. You will then receive your User ID (API key) via email. Keep this User ID safe and secure.

2. Choosing a WooCommerce USPS Plugin

While you *could* code the integration from scratch, it’s significantly easier and more efficient to use a dedicated WooCommerce USPS plugin. Several plugins are available, both free and premium. Here are a few popular options:

WooCommerce USPS Shipping Plugin by PluginHive: A robust premium plugin with advanced features.
USPS Shipping Method by WooCommerce: A simpler, official plugin from WooCommerce.
EasyPost (via plugin): While EasyPost is a paid service, it simplifies USPS and other carrier integrations.

For this guide, we will focus on general principles that apply to most plugins.

3. Installing and Configuring the Plugin

1. Install the Plugin: In your WordPress dashboard, go to Plugins > Add New. Search for your chosen plugin and click “Install Now” followed by “Activate.”

2. Access the Plugin Settings: Navigate to the WooCommerce settings (WooCommerce > Settings) and look for the shipping tab. You should see the USPS shipping method listed.

Fallback Rate: A default shipping rate to use if the API fails to return a rate.

Accurate package dimensions and weight are critical for obtaining correct shipping rates. Most plugins offer options for defining how WooCommerce handles package information. Common approaches include:
