Hello All. I have recently started with Open Project, and as this is my first time working with API and JSON I have a few questions about some of the endpoint uses. My first question is if there is a method to generate new custom Types and custom Fields using the API client. I have reviewed the documentation, and while there are Get commands available for the custom fields, there is no information about using Post. I attempted anyways which, unsurprisingly, was inaccessible. Does anyone know of any work-arounds that would allow access to this capability? 

My second question is regarding the Custom Option endpoint. The documentation on this endpoint is rather sparse. Can anyone provide me more information about what this endpoint does and can be used for?

Third, I have spend some time reading the information available regarding the Forms endpoints for projects, workspaces, etc. However, I am still not fully understanding the purpose behind the Forms and what they are used for. Can anyone provide more clarification about the Forms and examples of use cases?

Thank you in advance for your help!
