Coming soon
The TrueNAS REST API is deprecated in TrueNAS 25.04 and replaced by the TrueNAS API Client. Full removal of the REST API is planned for a future release.
This new API Client is not the deprecated TrueNAS CLI (midcli). The API Client is integrated in TrueNAS 25.04 onwards. It provides the
midclt
command-line tool, and the means to easily communicate with middleware using Python to make calls through the websocket API.This API client allows for better integration of TrueNAS into third-party solutions. Use this as a reference for projects that require direct TrueNAS integration.
TrueNAS API documentation remains available in the UI and through the TrueNAS Documentation Hub.
