Square WebPay support thread.

[Brent]

The WebPay module works great.

When I go to old orders which have been paid with the old Square payment module, I can not see what the customers ordered. I get an error
PHP Fatal error: Uncaught Error: Undefined constant "MODULE_PAYMENT_SQUARE_APPLICATION_ID" in /includes/modules/payment/square.php:544

I followed the upgrade instructions here: https://docs.zen-cart.com/user/payment/square/
In those instructions a new application is created for the WebPay module on the Square site. So Application ID and Application Secret are different form the old application used for the old Square module. I guess this is the reason the old orders do not show up.
Now I wonder if I change Application ID and Application Secret in the new WebPay module to the former ID and Secret, the old order will be displayed again.

I just could try it, but I got the shop running and do not want to risk messing everything up.

SO I want to ask if anybody got experience with this.

Have a look at post 131
It isn't strictly the correct way to do it as it doesn't fix the root cause but does solve the problem (if you don't need to keep track of which module was used to take the payment).
