Server Addons can evaluate characteristics of requests and affect them in groups to update them to a new status or perform tasks such as send emails. These tasks are system-wide actions and often run on a daily basis based. For example, a Server Addon could check requests in the Checked Out to Customer status a week before the expiration or due date and send an additional email to remind patrons of items that have not been picked up or viewed. The Server Addon tab in the Customization Manager facilitates the installation and management of custom Server Addon scripts that you can create to perform certain processes automatically without staff intervention, such as routing items and adding or removing flags. Unlike Client Addons, Server Addons run in the System Manager. They are stored in a database table instead of the file system, and can be created and modified easily from within the Customization Manager.
