The Webhooks plugin allows Obsidian users to integrate their notes with a variety of external apps and services using webhooks. This plugin enables automatic note creation, updates, or appends in Obsidian based on triggers from services like IFTTT or Zapier. Users can automate note-taking processes such as capturing song likes from Spotify, recording reactions from Slack, or saving notes through voice commands from a Google Assistant. The plugin works in conjunction with an online service that generates a unique webhook URL, which can be used to configure triggers in external automation tools. This functionality empowers users to automatically collect and organize data from different platforms directly into their Obsidian notes.
