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:

1 2 ... 206 207 208 209 210 211 212 213 214 215 216 ... 297 298
