The DocBase (Unofficial) plugin allows users to synchronize notes between Obsidian and DocBase, a collaborative documentation platform. With this plugin, users can pull existing notes from DocBase into Obsidian by specifying the note ID and push updates back to DocBase seamlessly. The plugin supports synchronization of note content, titles, tags, and draft statuses, helping users maintain consistency between both platforms. It requires an API token and team domain to establish the connection.
