How do I adjust an existing Pre-Auth?


  Pre-auths allow you to reserve funds in advance of a future transaction. During this time, while no funds have actually left the customer's bank account, these reserved funds are unavailable to the customer for other purchases.

The instructions below are for adjusting the amount of a pre-auth that has already been processed.
