Getting Transaction Data

US only. If you use the Amazon Web site to determine a transaction ID, you can get information about that transaction with the TransactionLookup operation. The returned information includes the transaction totals, tax and shipping charges. No information about the buyer or the products in the order is revealed through this operation. The TransactionLookup operation has only one parameter, TransactionId which specifies the transaction to query.

A REST request to retrieve transaction information would look like this:

    &AWSAccessKeyId=[ID]
    &Operation=TransactionLookup
    &TransactionId=[ID]
