Implementing Parallel Payments
Not only can Express Checkout support payment between a single buyer and merchant, but it
can support parallel payments. Parallel payments enables a single buyer to pay multiple
merchants in a single checkout session.

About Parallel Payments
Parallel payments enables buyers to pay multiple merchants on a marketplace in a single
Express Checkout session.
An online travel agency marketplace is a typical example of parallel payments in use. The
buyer purchases airline tickets and makes reservations from various merchants such as hotels,
car rental agencies, and entertainment venues hosted on the site. By implementing parallel
payments through Express Checkout, the marketplace host accepts PayPal as a payment
method. The host also provides the buyer with a consolidated order on the PayPal Review
page, summarizing expenses, itineraries, and other supporting information. Buyers see travel
information, including cancellation fees, directly from the supplier on the Transaction Details
page and in an email message.
