This section describes how to process a pre-authorization for an initial amount in Local mode. A pre-authorization transaction places a temporary hold on the customer's payment card, which can be captured at a later time.
Most authorizations expire in 5 to 7 days. The issuing bank sets the length of time before expiration. When an authorization expires with the issuing bank, your bank or processor might require you to re-submit an authorization request and include a request for capture in the same message. For more information, see Processing a Capture.
