I found some API on http://127.0.0.1:6391 but no way to update bookmark metadata. If I make re-import with edited metadata after import all metadata will re-fetched. I can map specific range of requests to tools like Proxyman and map requests to replace open graph tags but it overcomplicated. I need programmatically update: Title Description Comment Folder Tags Starred Icon Image For example Method update ' http://127.0.0.1:6391/update ' with body: {"id":"bookmarkId","comment":"some comment","tags":["watch-later"],"folder":"","starred":false, "url": "new url", "iconUrl": "url to new icon", "imageUrl": "url to new image" }
