PayPal integration is enabled by default. It may only be used by prepaid customers, because it requires the customer to manually initiate the payment.

To configure PayPal integration

1. Go to Settings » Commerce, and enter the email address of your PayPal account.
2. Ask any resellers who have a PayPal account to do the same.
3. When logged in as a prepaid customer, go to Settings » Payment, click the "Top up account" link, and follow the prompts to do a manual topup.
4. Back in your own customer, verify that the customer's balance has increased. This happens when PayPal notifies Enswitch that the payment was successful, which should be within a few minutes.
