is caused by using an old version of the Square WebPay plugin (version 1.0.4) from the plugins library and expecting it to work with newer versions of PHP.

It has nothing to do with your API version.

The plugin library version of the Square WebPay plugin does NOT work with newer versions of PHP. That's why when you go to

https://www.zen-cart.com/downloads.php?do=file&id=2345

it says at the top:
Please note: PHP8.1+ requires a paid upgrade; purchase through https://mxworks.cc/?product=zen-cart...in-for-php-8-x
Is anyone updating the Square plugin to work with PHP 8.0 or are we stuck with mxworks?
