powerEvents is a Vault extension, which allows you to take advantage of the Vault client events, such as check-in/-out, lifecycle change and the like.
You can write custom code that shall be executed on the according event via PowerShell.
Let’s say you like to fill or empty some properties on lifecycle change, or like to automatically rename files on import via drag&drop, or prevent the lifecycle transition when a combination of properties does not match your rules, etc.
powerEvents makes it easy to create such logic in a simple PowerShell script.
