--- title: ZITADEL Actions sidebar_label: Actions --- An Identity and Management system is a very interactive place. ZITADEL has built in functionality to react to its events. This functionality is called **Actions** and can be accessed from your organizations top navigation. Actions menu Actions allow you to define scripts which are then run on certain triggers. To add an action, click at the **new** button and provide a script and a name. You can specify a timeout and whether the action is allowed to fail too. Create Action To run those scripts, a flow with a trigger has to be created. This could for example be an **External Authentication** Flow, with a **Post Authentication** trigger. Flow Now whenever a user gets authenticated externally with an IDP, an action is triggered after the authentication itself. If you want to know more where actions can be useful, take a look at the feature [here](/concepts/features/actions) or directly jump to an example of a custom behavior [here](/guides/manage/customize/behavior).
