If you want to accept payments through PayPal, enable it as an option from the store > payments section of your dashboard.
New sites are automatically set up for payment through PayPal, with the email address given. If you want funds to go to a different account, you can specify the other account here.
When the customer checks out and selects PayPal as the payment option, the order will be placed into the Pending state, and the customer will be redirected to the PayPal site for completion of the order.
Customers do not need to have a PayPal account in order to pay. They can also pay with credit or debit cards.
When the customer completes the payment, PayPal's servers send your IndieMade site a message (called an Instant Payment Notification, or IPN) informing it of the sale. On receipt of this message, the order is placed into the Payment received state, and the order is ready to be processed.
