I saw where you uploaded a new version of the plugin on another post and uploaded that with no help.
I went to USPS website and created a new account and still not working.

Hey did you ever get a resolution for this error. I'm currently going through the same exact headache. I contacted This email address is being protected from spambots.

I'm certain many are getting the same error as well.

Out of curiosity, is this related to the Web Tools API being retired on January 25, 2026, per postalpro.usps.com/node/13834 ?

USPS says to migrate to the new USPS APIs by then.

All of HikaShop's documentation and plugin language are still using Web Tools, so I am a little confused about whether we need to do anything.

Glad I mentioned it then.

I first heard of it yesterday when I found an email from USPS API Communications This email address is being protected from spambots. You need JavaScript enabled to view it.> dated 3/6 in my spam folder.

Apparently, they sent one back on 2/14, too, which was also in my spam folder.

Is there any documentation, or are the options and settings very similar to those of the current USPS plugin, just using the new API?

I'm asking because the USPS.com Apps area is a bit different now, and you get a "Consumer Key" and "Consumer Secret."

I assume we don't need a callback URL either, and that "Public Access I" APIs are fine (all I see).

Thanks!

I'm now getting around to testing out the new plugin, and I can see in the USPS dev dashboard that API calls are being made.

However, I'm getting no results in HikaShop.

A couple of things are confusing - I cannot find a "USPS Account Number" anywhere in my profile, and I'm unsure what to set the USPS Account type to.

Some options that seem to be missing from the old USPS plugin, which were important before and I think might still be, are:

I'm assuming it is using developers.usps.com/domesticpricesv3#tag...st-base-rates-search :
So I'm not sure what if these required variables are being set statically: rateIndicator, processingCategory, destinationEntryFacilityType, and priceType

I think Container might be processingCategory now, but no way to set it, so I'm not sure what it's defaulting to if it is.

FYI for anyone else, it appears that First Class is now also USPS_GROUND_ADVANTAGE.

I'm not sure if this is due to missing language file entries or something else.

I'm not sure where or what the debug information goes when it's turned on.

I highly recommend incorporating the hasNonstandardCharacteristics option if you are using the API that requires it due to nonstandard packages:

Package is nonstandard. Nonstandard packages include cylindrical tubes and rolls, certain high-density items, cartons containing more than 24 ounces of liquids in one or more glass containers, cartons containing 1 gallon or more of liquid in metal or plastic containers, and items in 201.7.6.2.

That is common in several of the clients I work with.

I'll see if I can obtain a USPS account number, as it appears that this is only available to business accounts, not regular USPS or developer accounts.
