PayPal RESTful
PayPal RESTful is a new integration with PayPal which uses the PayPal REST API. It replaces both PayPal Express and PayPal Website Payments Pro … and also replaces PayPal Standard. (You may sometimes hear these integrations referred to as the “NVP/SOAP API integrations.”)
If you are using one of the older PayPal integrations, migrating to the RESTful module is highly recommended, and is quite straightforward.

PayPal RESTful will run on Zen Cart 1.5.7 or higher, and works on PHP 7.0-to-8.5.

PayPal RESTful is compatible with both standard three page checkout and one page checkout.
Storeowners who currently process orders using PayPal Express and/or PayPal Website Payments Pro will want to retire those modules when they enable PayPal RESTful - having both enabled will be confusing to customers.
Pay-Later / Pay-in-4 messaging is supported.
At this time, PayPal RESTful does not support Venmo.
