With the Payment Summary part, website users can view useful information about their payment pages. The payment summary can display the number of items on a payment page and the total cost for the items. It can also provide a link to view the payment page and pay for transactions. When you add a link and place the summary on a page template, a website user can access the payment page from any web page that uses that template. You can also use merge fields to create two versions of the summary: one for an empty payment page and one for a page with transactions.
When you create a payment summary, you select a Payment part to connect to the summary. For information about the Payment part, see Payment.
