When site visitors choose to buy an item or service or make a donation from your site, they will click the corresponding PayPal button to begin the transaction process. A PayPal Payment Details page will open in a new browser window, displaying information about the transaction and prompting the visitor to either sign in to their existing PayPal account or create a new account.
Once a visitor has signed in to or created a PayPal account, they will see a more detailed payment page on which they can review details of the transaction and enter shipping and other information, if applicable.
To complete the transaction and submit payment to your PayPal account, the visitor will click the Pay button at the bottom of the page or, to cancel the transaction, select Cancel. The visitor will then see a page confirming either that the payment was successfully submitted or canceled, and continue to a confirmation page.
The transaction process complete, your visitor can now close the new browser window and return to your site in the original window.
