The native YouTube UI currently supports multiple content types: videos, community posts (photos, GIFs, polls) & stories.
The YouTube Data API makes it very clear how to upload videos but I am not able to find information about the other two content types mentioned above, namely community posts & stories.
I did read this other Stack Overflow thread, which is essentially about access existing content from the Community tab through the API, but I was not able to find any additional information about posting new content to the Community tab through the API.
Does anyone know whether the YouTube Data API currently supports uploading community posts & stories to YouTube?
