Order Cancellations and Refunds

Topics

There are times when the sender decides to cancel a prepaid or postpaid payment token. Amazon FPS does not refund payments made to fund the prepaid instrument using FundPrepaid. You can, however, enable users to get refunds (credits) for items purchased with a prepaid or postpaid token that they returned. Senders might seek a refund when, for example, a item goes out of stock and therefore can't be delivered on time or when there is a problem with the product.

This section describes how to cancel prepaid or postpaid payment tokens and, optionally, give refunds.

Canceling a Prepaid or Postpaid Payment Token

The Amazon Payments web site, payments.amazon.com, enables senders to cancel prepaid or postpaid transactions from their user accounts. To provide transaction cancellation functionality on your web site, use the following procedure.

To cancel prepaid or postpaid payment tokens

On your web site, create a form that enables the sender to search for and find the prepaid or postpaid payment token to cancel.
Obtain from that transaction the TokenId.
Submit a CancelToken request using those values.
For more information about this action, see CancelToken.

The following CancelToken request cancels a prepaid payment token specified by its TokenId.

  Action=CancelToken&
  AWSAccessKeyId=0656Example83G2&
  SignatureVersion=1&
  Timestamp=2007-08-06T13%3A00%3A01Z&
  TokenId=254656Example83987&
  Version=2008-09-17&
  Signature=<URL-encoded signature value>

Senders should only be able to use CancelToken to cancel payment tokens associated with their own accounts.

Refunding a Prepaid or Postpaid Transaction

The Refund action gives you the option of crediting a prepaid balance or postpaid balance for items returned. You can only give a refund once the sender's payment instrument has been charged.

You can use the optional parameter RefundAmount, to refund part or all of a transaction. For example, a sender purchases $100 worth of goods from a merchant with $3 in credit card fees paid by the merchant. You can, for example, refund $50 if you like. In a partial refund, the amount of the transaction fee returned is proportional to the amount refunded. In this case, the amount refunded is $1.50.

To provide transaction refunding functionality on your web site, use the following procedure.

To refund a transaction

On your web site, create a form that enables the sender to search for and find the transaction to refund.
Obtain from that transaction the TransactionId and/or the CallerReference.
Whenever you send a Pay request, the response includes both the TransactionId and the CallerReference both of which you should keep record of.

Submit a Refund request similar to the following.

https://fps.amazonaws.com/?
  Action=Refund&
  AWSAccessKeyId=0656Example83G2&
  SignatureVersion=1&
  Timestamp=2007-08-06T13%3A00%3A01Z&
  CallerReference=354897217&
  TransactionId=254656Example83987&

  Signature=[URL-encoded signature value]
