Refund API Operation

Refund Examples Using NVP and CURL

These examples all use NVP for the data binding and CURL to deliver the HTTP request to

the PayPal sandbox endpoint. Line breaks are provided for ease of reading; each CURL

command is a single line and each request and response is a string without line breaks or extra

whitespace.

Using the payment key to refund an entire payment

In this example, the caller of the Refund API operation specifies a payment key. The total

amount from each receiver is refunded to the sender.

NOTE: The sample code below uses the insecure setting to work around the certificate for

testing in a sandbox environment. For actual implementations, you must specify the

location of the certificate.

Request:

curl -s --insecure

-H "X-PAYPAL-SECURITY-USERID: api_username"

-H "X-PAYPAL-SECURITY-PASSWORD: api_password"

-H "X-PAYPAL-SECURITY-SIGNATURE: api_signature"

-H "X-PAYPAL-REQUEST-DATA-FORMAT: NV"

-H "X-PAYPAL-RESPONSE-DATA-FORMAT: NV

-H "X-PAYPAL-APPLICATION-ID: your_app_id "
