I made my first addon for Cockpit v2: GitHub - witsec/cockpit-api
This addon adds a couple of additional endpoints for the following functionalities:
- Upload files through the API
- Delete one or more files
- Get a list of all folders (useful for when you need a folder ID when uploading files)
- List all entries (published and unpublished) of a model
I hope it’s of use to others. Feel free to grab what you want and tweak it to your liking.
