PayPal RESTful API Payment Module

This Zen Cart payment module (paypalr) combines the processing for the PayPal Payments Pro (paypaldp) and PayPal Express Checkout (paypalwpp) payment modules that are currently built into Zen Cart distributions. Instead of using the older NVP (Name Value Pair) methods to communicate with PayPal, this payment module uses PayPal's now-current REST APIs and combines the two legacy methods into one.

The module's operation has been validated …

1. With PHP versions 7.4 through 8.3; PHP 7.3 will result in fatal PHP errors!
2. In Zen Cart's 3-page checkout environment (v1.5.8a and v2.0.0)
3. With One-Page Checkout (OPC), v2.4.6
   
   1. Using OPC's guest-checkout feature.
   2. Both requiring confirmation and not!
   
   
4. With both the built-in responsive_classic and ZCA Bootstrap (v3.6.1) templates.

For additional information, refer to the payment-module's wiki articles.

:beta:Please note: The current release (v1.0.0-beta4) is a beta version! While I've tested it extensively, I suggest giving it a try on your test site using a PayPal sandbox account first.

Guest checkout, first test after configuration, clicked PayPal button... no checkbox/radio button seems very confusing with the express button on the checkout/payment page. The button is clickable, but goes no where.

So I click it, then confirm order and it fails to the following page & error.

You missed the root-directory file ppr_webhook_main.php; that's where the 404 came from. Zen Cart 1.5.8 or 1.5.8a?

There is still no radio/checkbox for the payment module. Noting it is the only payment displaying.

Please note that I've only tested with zc158a and the current zc200-alpha. I won't be supporting any other Zen Cart base for the usage.

There is no radio/checkbox for the module since you've only got that one payment module installed. I'll rethink the means of identifying which (PayPal vs CC) sub-option is selected, but IMO using a radio/checkbox for the sub-option is ugly.

Maybe a selected state behavior, like a border? and the credit card one doesn't look at all like a selectable option, would need "buttonized" or something
