Virtual Card Events API

The Purchase Transactions API allows you to recognize when a virtual card has moved from one status to another. In particular, when you want to know that a virtual card has been authorized or cleared for settlement, you can make the Purchase Transactions API request either for a specific virtual card or for multiple and look for certain Type/Status combinations. In the example given above, if you want to see all virtual cards that have been authorized or cleared for settlement you would look for the following Type/Status combinations:

authorizationCLEAREDAuth approved, cleared for settlement
authorizationPENDINGAuth approved, pending settlement
authorization.clearingCOMPLETIONAuth settlement complete
