Refund API Operation
Use the Refund API operation to refund all or part of a payment. You can specify the amount
of the refund and identify the accounts to receive the refund by the payment key or tracking
ID, and optionally, by transaction ID or the receivers of the original payment.
Refund API Overview
PayPal supports refunds made manually, via the PayPal account interface, or by means of the
RefundTransaction API. The terms sender and receiver refer to sender and receivers of the
original payment using the Pay API operation. When making a refund, the sender’s account
receives the refund and the receivers’ accounts are the source of the refund. Refunds are made
from one or more receivers to a sender.
To make a refund using the Refund API operation, you must:
 have made a Pay request for which payment you want to refund the payment, or you must
have received the part of the payment you want to refund, and
 have permission to make a refund on behalf of the receiver, unless you are also the
receiver; in other words, each receiver whose account is the source of the refund must have
granted you third-party access permission to call the Refund API operation.
NOTE: A receiver can grant you third-party access to make a refund by logging in to
PayPal, choosing API Access on the Profile page, then clicking the link to
Grant
API permission and selecting Refund after clicking Configure a custom API
authorization.
NOTE: The Adaptive Payments Refund API call does not support pay keys generated by
the Mobile Payment Library (MPL).
For each kind of refund, you must specify values for the following fields:
