Payment Summary 2.0 part works with Payment 2.0 parts to provide website users a summary view of their payments. 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. You can also include a summary grid that lists the items added to the cart and provides a brief description of each. 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 2.0 part to connect to the summary. For information about the Payment 2.0 part, see Payment 2.0.
