Processing a Pre-Authorization {#ttp-sis-pymnt-svcs-pre-auth-api-intro}
=======================================================================

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](/content/cybsdeveloper2021/amer/en/docs/cybs/en-us/tap-to-phone-sis/integration/all/rest/tap-to-phone-sis/ttp-sis-pymnt-svcs-intro/ttp-sis-pymnt-svcs-capture-api-intro.md "").
