# Check GTM Event

Check GTM Event inspects the Google Tag Manager `dataLayer` for an event or property you expect. Use it to prove analytics fired after a user action.

## When to use it

* Confirm a purchase or signup event reached the data layer.
* Assert a property on an event when `Event Property` mode is selected.
* Run after the user action that should trigger the tag, with a short wait if the push is async.
