I've had the Paypal express for many years, but I first set up the Paypal Pro back in 2016. The only changes I had to make was some security requirements required by Paypal, on the server..TLS, etc.
Other than that, nothing has changed. The main reason for me changing it to "Auth Only" is because of the Paypal fees not being refunded. Sometimes a customer clicks the order button multiple times causing multiple orders and payments. I used to simply refund them, but I'll be losing money every time since I don't get refunded the fees.
Thanks
Well, the reason I asked about the history of the shopping cart, is that over time (and over versions), there are settings that have been added/removed. Its really only been in the most recent version or two where the upgrade path actually automatically adds the missing/modified keys rather than the old method of removing the payment/shipping module and then reinstalling it into the Zen Cart store... The above doesn't necessarily fill in the blanks and I haven't done the homework (can't remember) what version of Zen Cart was released at or around August 2014 (account creation date), though I thought it was some version before Zen Cart 1.5.5f.
Anyways, the point is that it is possible (known) that the software supports an authorize only option (especially important when dealing with all of the fees), but that option has to be made available for selection which is "best"/"easiest" done by removing and reinstalling the database settings (the files do not get removed or anything, its just that the settings in the database get removed and installed which requires entry/reentry of those credentials and setting of any changes that have been made or want to be kept.
