How do I use the API to set a timeline column type value as a milestone?
I can set the the from and to with the API but there is no milestone option. If I manually mark a timeline value as a milestone through the website, then I update the date using the API it remove the milestone flag.
There are indeed bits and pieces missing in the doc. What I do in these cases is to setup the column in the UI as required (in this case with a milestone timeline) and query the column in the API playground.
