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 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.
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.
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).
