Payment Gateway: PayPal


Can I add Paypal as a Payment Gateway?

Yes, PayPal can be integrated as a Payment Gateway. You can use a PayPal account that is connected to another cart as long as that cart does not have limitations of only their connection.

If you have more than one PayPal account, you will repeat the process below for each setup. Just be careful to watch which PayPal you are adding to your products so you can make certain your funds are going to the correct accounts.
