Customer LoginCheckout: PayPal (Standard)
The WordPress shopping cart plugin is fully compatible with the PayPal Website Payments Standard payment gateway and will work with any PayPal account.
Setting up PayPal
PLEASE NOTE: You require a PayPal Premier or Business account for the IPN functionality to work. IPN settings are not available inside PayPal Personal accounts. If you already have a PayPal Personal account, you can easily upgrade it to Premier or Business from the PayPal Sign Up page.
The plugin makes use of the PayPal IPN (Instant Payment Notification) in order to be notified of completed orders to update the database internally and notify the administrator that an order has been processed. In order for the PayPal IPN to work, you’ll need to log into your PayPal account and set some configuration settings in your PayPal ‘Profile’ section. Do the following 2 things…
In the PayPal ‘Profile’ section, under ‘Selling Preferences’, go to the ‘Website Payment Preferences’ link. Make sure that the very first option ‘Auto Return’ is turned OFF. Scroll down until you find the section named Payment Data Transfer (PDT) and be sure to turn it OFF.
In the PayPal ‘Profile’ section, under ‘Selling Preferences’, go to the ‘Instant Payment Notification’ link where you’ll need to enable the IPN and fill in the appropriate URL for notifications to be sent to. The URL needs to be an absolute address to your WordPress shop with ‘?wpcomethod=coreturn&type=pp’ appended to it. Ex. http://domain.com/?wpcomethod=coreturn&type=pp
Plugin Configuration Settings
The PayPal payment method can be enabled and configured in the ‘Configuration’ section of the plugin. Be sure to tick/check the PayPal checkbox in order to enable it first and then go ahead to fill in the following configuration settings.
PayPal Email Address
Your registered PayPal seller account email address
Invoice Prefix
A value which will be prepended to all invoice numbers sent through to PayPal. This is an optional setting and you may leave it blank to just use the order ID as the invoice number.
PayPal SandBox
Set this to “Yes” for a development site. Turn this feature off for a production site. The PayPal sandbox allows you to submit test orders through the PayPal interface in order to test your software. Please visit PayPal Developer Central for more information. Instructions for using the PayPal Sandbox with the Checkout plugin are HERE.
