I originally picked up development of this plugin to add a couple of improvements for I think folder validation. After the original developer ceased activity I was asked by a couple of people in the community to pick it up. I did so and made a few other changes. It was never meant to be anything more. Now, after multiple attempts to get the plugin official registered, and requests coming in for further changes I need to pull the pin now. I am unable to commit to this project any further. I don't even use it myself, preferring the Obsidian Web Clipper for article capture without the intervening need for Wallabag.
This plugin for Obsidian allows you to sync Wallabag items into Obsidian notes in various ways. It works with the official hosted Wallabag environment, or your self-hosted version. The plugin is hosted at https://github.com/quantumgardener/obsidian-wallabag.
The plugin is fully documented in the plugin wiki.
