Set up Getwello with Obsidian

Obsidian doesn't accept webhooks natively. The Local REST API community plugin exposes endpoints for appending to notes. Pair with a relay to format markdown.

What you need

• Obsidian installed with a vault.
• The Local REST API community plugin (free).
• A relay reachable from the internet.
• A Getwello Coordinator account with active subscription.

Step 1: Install Local REST API in Obsidian

1. Settings → Community plugins → Browse.
2. Search “Local REST API”. Install + Enable.
3. Open the plugin settings. Note the access token. Optionally enable HTTPS.

Step 2: Expose Obsidian to the internet (carefully)

The plugin listens locally. Use a Cloudflare Tunnel or Tailscale to reach it from outside. Bind to a long random path and require the auth token.

Step 3: Build the relay

Worker that receives our event, formats markdown, calls Local REST API to append to today's note:

export default {
  async fetch(req, env) {
    const evt = await req.json();
    const today = new Date(evt.occurred_at).toISOString().slice(0, 10);
    const md = evt.event === 'check_in.created'
      ? `- ✓ Check-in ${evt.occurred_at.slice(11, 16)} · mood ${evt.data.mood ?? 'n/a'}\n`
      : `- ⚠ ${evt.event}\n`;
    await fetch(`${env.OBSIDIAN_URL}/vault/daily/${today}.md`, {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${env.OBSIDIAN_TOKEN}`,
        'Content-Type': 'text/markdown'
      },
      body: md
    });
    return new Response('ok');
  }
};

Step 4: Create the Getwello webhook subscription

Settings → Developer API → Webhooks. URL is your relay. Tick all four events.

Test

Click Test. Open today's daily note in Obsidian. The entry should be appended within a second or two.

Troubleshooting

Daily note doesn't exist: the POST creates it if missing in v3+ of the plugin. Otherwise use the Daily Notes core plugin to ensure today's note exists.

Entries appear out of order: append is by arrival time, not event time. If you want time-sorted entries, fetch the note, sort, write back.
