Order Payment Action for Express Checkout
10
110 May 2010 Express Checkout Integration Guide
An authorization enables you to capture multiple payments up to 115% of, or USD $75 more
than, the amount you specify in the DoExpressCheckoutPayment request. Choose this
payment action if you need to ship the goods before capturing the payment or if there is some
reason not to accept the payment immediately.
The honor period, for which funds can be held, is three days. The valid period, for which the
authorization is valid, is 29 days. You can reauthorize the 3-day honor period at most once
within the 29-day valid period.
You can void an authorization, in which case, the uncaptured part of the amount specified in
the DoExpressCheckoutPayment request becomes void and can no longer be captured. If
no part of the payment has been captured, the entire payment becomes void and nothing can be
captured.

Order Payment Action for Express Checkout
An order payment action represents an agreement to pay one or more authorized amounts up
to the specified total over a maximum of 29 days.
To set up an order, specify the following payment action in your SetExpressCheckout and
DoExpressCheckoutPayment requests:
PAYMENTACTION=Order
An order enables you to create multiple authorizations over the 29 days; each authorization
you create places the buyers funds on hold for up to three days. You can capture multiple
payments for each authorization, up to 115% of, or USD $75 more than, the amount you
specify in the DoExpressCheckoutPayment request.
NOTE: The default number of child authorizations in your PayPal account is 1. To do
multiple authorizations please contact PayPal to request an increase.
This payment action provides the most flexibility and should be used when either a sale or one
authorization plus one reauthorization do not meet your needs. Situations in which orders are
appropriate include the handling of
z Back orders, in which available merchandise is sent immediately and the remaining
merchandise is sent when available, which may include more than two shipments
z Split orders, in which merchandise is sent in more than one shipment, perhaps to different
addresses, and you want to collect a payment for each shipment
