To settle a transaction

Send a request to the Amazon Flexible Payment service similar to the following.

https://fps.amazonaws.com/?
  Action=Settle
  &AWSAccessKeyId=[Your access key Id]
  &TransactionId=208sg0849sfwers082
  &Timestamp=2007-05-10T05%3A11%3A41Z
  &Version=[WSDL version in the YYYY-MM-DD format]
  &Signature=[calculated signature]
  &SignatureVersion=2
  &SignatureMethod=HmacSHA256

The request includes the TransactionId, which identifies the transaction to be settled. If a value for the optional parameter, SettleAmount is not included, the entire purchase price is settled.

Among other values, Amazon Flexible Payments Service returns TransactionStatus, which specifies whether the request completed successfully or not.

For more information about the action, its parameters, and return values, see Settle.
