How do I set up a Paypal Credit Card Gateway?

You can set up a credit card gateway to accept credit card payments using Express Invoice, including the PayPal Payflow Pro gateway. To set up the gateway for PayPal, open the Options dialog and click the Payment Methods tab. Select PayPal Payflow Pro from the list (click Check for Updates if no gateways appear in the list), then click Options to open the PayPal Account Settings. For more information on adding a gateway plugin to Express Invoice, visit Integrating Payment Modules.

1. You should already have a PayPal account.
2. Enter the API Username and Password provided to you from PayPal.
3. The Gateway URL is https://api-3t.paypal.com/nvp, though you may want to test the gateway in the sandbox using the URL https://api-3t.sandbox.paypal.com/nvp.
4. For API Credentials, you will select 3-token Authentication and enter the signature provided by PayPal. If you have your own SSL certificate, select Client Side SSL, enter the certificate password and browse for the certificate file.
