Look directly underneath the Transaction Details headline at the top of the page to find the type of purchase -- debit card or credit card, for example -- and an alpha-numeric code called the Unique Transaction ID.The Unique Transaction ID is the 17-character code that uniquely identifies each PayPal transaction.
