Hi @cscarola, because of the complex and numerous access control rules, it is not possible to determine an exact list of users that can modify a task, even if you did make all those API calls. Even a “public vs. private” flag would not accurately convey who can modify a task, as a task could be publicly _visible_ but be in a comment-only project and therefore is not editable to all users.
