If you already accept credit cards online, you can set up Express Checkout with PayPal to integrate with your site. The PayPal option can enhance your campaign success by giving your donors the reassurance of a known and secure payment method. This option also reduces your liability for holding cardholder data, because their credit card information is stored securely at PayPal.
The Payment Creator iPart supports the PayPal Express Checkout panel when it appears outside of the context of the shopping cart, on a standalone donation page.
See PayPal Express Checkout Integration in Payment Authorization for how to set up PayPal support.
