Find the namespace for REST API call /rest/ui/components/{namespace}

Hi,

I am trying to get a bit more acquainted with the REST API and downloaded the documentation. Unfortunately, for a few calls there are undocumented parameters. E.g. I would need to have some sample “namespaces” to get access to /rest/ui/components/{namespace}. What I want to achieve is to have a JSON response that contains the details of my widget developments. I have done the same with rules and found a way to extract the script source, so I can regularly sync it with my GitHub repositories. I now want to do the same with widgets and assume the content is “behind” an API call ti /rest/ui/components/{…}. I tried Widgets, widgets (both singular) metadata, any many more. Just always with an empty result. Can anyone help?

Cheers P.
