PayPal Payments Standard (Older PayPal service, less reliable than Express Checkout)
Manage your PayPal account.

Configuration Instructions:
1. Sign up for your PayPal account - click here.
2. In your PayPal account, under "Profile",

set your Instant Payment Notification Preferences URL to:
```
'.str_replace('index.php?main_page=index','ipn_main_handler.php',zen_catalog_href_link(FILENAME_DEFAULT, '', 'SSL')) . '
```
(If another valid URL is already entered, you may leave it alone.)
Be sure that the Checkbox to enable IPN is checked!

in Website Payments Preferences set your Automatic Return URL to:

'.zen_catalog_href_link(FILENAME_CHECKOUT_PROCESS, '', 'SSL',false).'

... and click "install" above to enable PayPal Standard support... and "edit" to tell Zen Cart your PayPal settings.

Requirements:

*PayPal Account (click to setup/configure)
*CURL with SSL is strongly recommended
*Port 80 (and port 443 if SSL is enabled) is used for *bidirectional* communication with the gateway, so must be open on your host\'s router/firewall.
*Settings within your PayPal account must be configured as described above.' ); } else { define('MODULE_PAYMENT_PAYPAL_TEXT_DESCRIPTION', 'PayPal'); } // to show the PayPal logo as the payment option name, use this: https://www.paypal.com/en_US/i/logo/PayPal_mark_37x23.gif // to show CC icons with PayPal, use this instead: https://www.paypal.com/en_US/i/bnr/horizontal_solution_PPeCheck.gif // You should only use choices listed on this page: https://ppmts.custhelp.com/app/answers/detail/a_id/632 define('MODULE_PAYMENT_PAYPAL_MARK_BUTTON_IMG', 'https://www.paypal.com/en_US/i/logo/PayPal_mark_37x23.gif'); define('MODULE_PAYMENT_PAYPAL_MARK_BUTTON_ALT', 'Checkout with PayPal'); define('MODULE_PAYMENT_PAYPAL_ACCEPTANCE_MARK_TEXT', 'Save time.
