Studio Backend Events

The Studio Backend Bundle dispatches events that allow customization of API responses and element resolution behavior. These events use the Symfony EventDispatcher and follow the EventSubscriberInterface pattern.

The two main event categories are:

  • PreResponse events - fired before the API returns a response for an element (asset, data object, document). Use these to add custom attributes, modify response data, or inject additional information into the API output.
  • ElementResolveEvent - fired during element resolution to customize how elements are looked up by ID or search term.

Key event classes:

  • Pimcore\Bundle\StudioBackendBundle\Asset\Event\PreResponse\AssetEvent - fired before asset API responses
  • Pimcore\Bundle\StudioBackendBundle\DataObject\Event\PreResponse\DataObjectEvent - fired before data object API responses
  • Pimcore\Bundle\StudioBackendBundle\Document\Event\PreResponse\DocumentEvent - fired before document API responses
  • Pimcore\Bundle\StudioBackendBundle\Element\Event\PreResolve\ElementResolveEvent - fired during element resolution
