Preauthorization is the first part of a two stage transactional process.

A Preauthorization verifies that a card is valid and has sufficient funds to complete the initiated transaction. If a transaction has been approved, the authorized amount is held until it has been captured or an expiry time has been reached, which is usually 7 days for Visa and MasterCard and 14 days for American Express transactions.
