How to pass snapshot id to zfs/snapshot/id/{id} endpoint?

[rmblr]

The 2.0 api has an /zfs/snapshot/id/{id} endpoint you can GET and DELETE.

Snapshot ids are the snapshot names which have the format like: tank/dataset@snapname. This results in a GET or DELETE request to /zfs/snapshot/id/tank/dataset@snapname which returns an 404.

The source is here, but isn't particularity illuminating.

What's the proper encoding for the snapshot id?

The answer is: url escape the name of the snapshot:

tank/foo@snapshot1 becomes tank%2Ffoo%40snapshot1
