USPS Extension problem Webtools API vs USPS API
(1/1)
perplexed:
Hello,
New to AbanteCart Cart and becoming aware after countless hours of forum reading and manual reading, that something deeper was going on besides configuration of the USPS shipping extension that was not working with test products.
So we sent a couple of error log entries to USPS API support and received the following reply (below_. It appears AbanteCart cart is using WebTools API which is now considered legacy by the USPS support people. The newer API is USPS API. Can someone please confirm that this is the case? If so are there any plans to migrate over from WEBTOOLS to USPS API? I would really like to stay with AbanteCart Cart as we like it. However, unable to get the USPS shipping extension functioning would be a deal breaker. Thank You,
Here is the response we received from USPS API support.
"Hello,
It looks like this online store (AbanteCart Cart) is using the Web Tools APIs, not USPS APIs. If you wish to continue to use AbanteCart Cart you will need to reach out to webtools@usps.gov. Otherwise you will need to find a different third party software that uses the USPS APIs.
Thank you,

Hello.
Did you try the third party extension?

I looked at the third party extension, and it is identically the same for setup. It allows for more enhancements but it appears to use the web tools API as well. So this would not work either. As an added note USPS API support has informed me that the webtools API for usps will retire on January 25th 2026. So it would appear the USPS extension as well as the third party USPS extension would break. The newer USPS API uses a more secure authentication process that requires a consumer key as well as a consumer secret key, as opposed to just a login and password. Stuck in a ditch......However Thank you for your response.
