I am developing an API using Python. Currently using Patreon library. According to developers manual/documentation in patreon. Unable to extract posts, likes and comments even after using V2.
Indirectly have extracted posts by using fetch_user().
But still, comments and likes are unable to be retrieved.
Extracting posts is supported, however details of some posts are not supported, like featured images in featured image posts. Likes comments etc as well. You can check out how WP plugin does it and adopt it for your code:
(Check that class for /posts related calls - more than one is there)
