USPS API Changes...
Posted: Thu Mar 29, 2012 4:23 am
Received this from the USPS today. Does this affect anything that will cause issues for Opencart (I'm on 22.214.171.124, but asking about Opencart in general, really).
Web Tools integrator;
As communicated first in May 2011, outdated versions of the Web Tools Domestic Rate Calculator API (Rate and RateV2) will be retired on March 31, 2012. At that time, requests to the Rate and RateV2 APIs will result in error message responses. If you are no longer sending requests to Rate and RateV2, please disregard this message.
Integrators should migrate to the current version of the Domestic Rate Calculator API (RateV4). Technical documentation is available at https://www.usps.com/business/webtools- ... guides.htm.
Thank you for your cooperation. Please let us know if you have any questions or concerns.
