On the heels of the recent USPS-initiated upgrade to their Rate and RateV2 services, comes further change on the horizon.
“Rate and RateV2 versions of the domestic Rate Calculator will be retired on March 31, 2012, requiring all integrators to migrate to the latest versions”
What does this mean for you?
ML8, version 220.127.116.11 and earlier + ML9, version 18.104.22.168 and earlier
If you are using the built-in USPS real-time shipping rates, you will need to take action before March 31, 2012.
We recommend that you upgrade your AspDotNetStorefront store to MSx/MultiStore in order to continue to use the USPS real-time rate services. MSx uses the recommended “RateV4″ version API in its built-in USPS integration, with no issues.
Custom Development Partners are aware of the upcoming changes and can best guide you in managing the right solution for your store.
How do I know which version I am running?
The easiest way to tell which version your store is running on is to open your Admin Console and look to the left column of your Home page.
This change will not affect your store. Continue operations as usual.
