We’re seeing this issue come up for a number of our clients, so we thought we’d put the word out for anyone who owns or operates an e-commerce website that is using USPS for shipping estimates and services.
If you fall into this category, you will want to conduct a test transaction on June 1st 2015 to ensure that USPS web tools updates did not adversely effect your website.
Thank you for using USPS Web Tools.
May 31, 2015 USPS Web Tools will be implementing modifications and additional features to the U.S. Postal Service APIs.
The following changes may especially impact shipping systems:
Origin ZIP Code required for Priority Mail International to Canada
Modified special services
Modified service IDs
Modified available mail classes for Merchandise Return Services
Detailed release notes are available on the Web Tools home page at USPS.com/webtools under the Web Tools Announcements section.
Included in the release notes are the URLs of the staging environments, which are now available to developers for testing.
