PayPal RESTful

The most-up-to-date PayPal Integration for Zen Cart

This module is now production ready: https://www.zen-cart.com/downloads.php?do=file&id=2382

Migrating to the RESTful module is highly recommended, and is quite straightforward.

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.

Links:

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

PayPal RESTful

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.

Pay-Later / Pay-in-4 messaging is supported.

At this time, PayPal RESTful does not support Venmo.
