Virtualmin API create-domain features-from-plan parameter

So I am using a Virtualmin remote API to create a virtual server in Virtualmin.

Here is my URI:


https://myip:10000/virtual-server/remote.cgi?program=create-domain&domain=foo.com&pass=asd456&features-from-plan=Bronze


What I am trying to do is to create a virtual server with features of a Bronze plan that I have defined (I have three plans defined: Bronze, Silver, Gold).

I am getting this response, however:


Unknown option Bronze

Adds a new Virtualmin virtual server, with the settings and features
specified on the command line.

Am I using the API wrong? Please help.
