GitHub user dosubot[bot] added a comment to the discussion: Adding new notification methods
<!-- Greeting --> Hi @Samuel-Sj! I'm [Dosu](https://go.dosu.dev/dosubot) and Iām helping the superset team. <!-- Answer --> To add a new notification method like Mattermost, Superset uses a modular system where each notification provider is a subclass of `BaseNotification` in `superset/reports/notifications`. You should create a new class for Mattermost, set a unique `type` attribute, implement the `send()` method, and make sure your new class is imported in `superset/reports/notifications/__init__.py` so it registers as a plugin. The Slack notification implementation is a good template to follow for structure and API integration logic [(example)](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/reports/notifications/slack.py). If your changes aren't being applied after rebuilding, common issues include: not importing/registering your new notification class, Docker image caching (try `docker compose down -v` before rebuilding), or placing your module in the wrong directory. Also, if you run into migration issues, you may need to manually reset the migration state [(instructions)](https://github.com/apache/superset/issues/34622). There isn't official documentation or community experience specifically for Mattermost, but the notification system is designed to be extensible, so following the Slack example should work well. If you share more details about your changes or error messages, I can help troubleshoot further. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
