Studio API Events

Alternative Element Trees are a Pimcore Studio plugin backed by Studio Backend endpoints. Before one of those endpoints returns, the bundle dispatches a pre-response event carrying the response schema. Listen for it to add your own data to the response.

This is the supported way to change what the Studio API returns. See the Studio Backend Additional and Custom Attributes documentation for the listener pattern and how the added attributes reach the frontend.

warning

The endpoints themselves are not a supported public API. Their controllers are internal and may change in any release without a deprecation path. Do not build integrations against them. Their current definitions are generated from the code and served at https://<your-pimcore-host>/pimcore-studio/api/docs, tagged Bundle Backend Power Tools.
