Had to also comment out the pyxb version enforcement at the top of https://github.com/AuthorizeNet/sdk-python/blob/master/authorizenet/apicontractsv1.py

I tested this with python3.11.7 and [email protected] and fixed apicontractsv1.py like this:

# Version of PyXB used to generate the bindings
_PyXBVersion = '1.2.7-DEV'

if you don't want to comment out the version check entirely...

I also need this. I may deprecate authorizenet in my app and tell my customers it is stripe only if this continues to block adopting updated python versions.
