This API allows you to pull back history of the Virtual Card. This is the same API (and data) that is used when clicking the “Transactions” button on the Virtual Card in the Portal to display the transaction history. The API will return the merchant name where the Virtual Card was used, the date and time, transaction type (auth, settlement, refund, void, etc.), the response/memo which correlates to the transaction type and the amount.
Virtual Card History Type and Status descriptions can be found here.
