USPS Shipping (RESTful) for Zen Cart

This module provides sellers a chance to offer United States Postal Service (USPS) shipping rates to customers during checkout. This is done by pulling the rates directly from the USPS' REST API.

This module supports versions 1.5.8 onward innately. (Support from 1.5.7 and backward is not necessarily guaranteed but is plausible. Read the Installation steps below for more details.) This script was primarily written with PHP8 in mind. (It might have problems working with PHP7.)

There isn't much difference between the two versions. However, if you managed to get the WebTools version to work, CONTINUE TO USE THAT VERSION.

USPS API Documentation: https://developers.usps.com/apis
This API takes advantage of four API's: Domestic Prices 3.0, International Prices 3.0, Service Standards 3.0, and OAuth 3.0.
