Interested in the API for FreeNAS:
The rewrite from the old API to the new middlewared continues. Once the API stabilizes and the rewrite is complete, will be deprecated and replaced by the new API documentation. In the mean time, to see the API documentation for the new middleware, log into the new UI, click on the URL for the FreeNAS system in your browser’s location bar, and add /api/docs to the end of that URL.
