Granola Webhooks & Events

Overview

Granola does not expose raw webhook endpoints. All event-driven automation flows through Zapier, which provides two trigger events. This skill covers the event model, webhook payload structure, event filtering, processing patterns, and building custom event handlers.

Prerequisites

Granola Business plan (for Zapier access)
Zapier account (Free for basic Zaps, Paid for multi-step)
Optional: custom webhook endpoint (Express.js, FastAPI, or serverless function)

Instructions

Step 1 — Understand the Event Model

Granola fires events through Zapier triggers, not direct webhooks. Two triggers are available:

Trigger	When It Fires	Use Case
Note Added to Granola Folder	A note is placed in a specific folder (automatic)	Auto-route by meeting type
Note Shared to Zapier	You manually click Share > Zapier on a note	Selective sharing for important meetings

Step 2 — Webhook Payload Structure

When a Zapier trigger fires, Granola sends this data:

{
  "title": "Sprint Planning — Q1 Week 12",
  "creator_name": "Sarah Chen",
  "creator_email": "sarah@company.com",
  "attendees": [
    {"name": "Sarah Chen", "email": "sarah@company.com"},
    {"name": "Mike Johnson", "email": "mike@company.com"},
    {"name": "Alex Kim", "email": "alex@external.com"}
  ],
  "calendar_event_title": "Sprint Planning",
  "calendar_event_datetime": "2026-03-22T10:00:00Z",
  "note_content": "## Summary\nDiscussed Q1 priorities...\n\n## Action Items\n- [ ] @sarah: Schedule design review..."
}

Key fields for filtering and routing:

attendees[].email — detect internal vs. external meetings
calendar_event_title — match meeting type patterns
note_content — search for action items, decisions, keywords

Step 3 — Event Filtering Patterns

Use Zapier Filter steps to route events:

Filter: Only External Meetings

Filter: attendees.email DOES NOT contain "@company.com"
(at least one attendee has a non-company email)

Filter: Only Meetings with Action Items

Filter: note_content contains "- [ ]"

Filter: Only Sales Calls (by title keywords)

Filter: calendar_event_title contains any of: "discovery", "demo", "sales", "prospect"

Filter: Long Meetings Only (> 30 min)

Use Zapier Code step to parse calendar_event_datetime and compare to note timestamp

Step 4 — Build a Custom Webhook Handler

Forward Granola events from Zapier to your own endpoint:

# Zapier configuration
Trigger: Granola — Note Added to Folder ("All Meetings")
Action: Webhooks by Zapier — POST
  URL: https://your-api.com/webhooks/granola
  Payload Type: JSON
  Data:
    title: "{{title}}"
    creator: "{{creator_email}}"
    attendees: "{{attendees}}"
    content: "{{note_content}}"
    datetime: "{{calendar_event_datetime}}"
    hmac: "{{your_webhook_secret}}"

Express.js handler:

// webhook-handler.js
import express from 'express';
const app = express();
app.use(express.json());

app.post('/webhooks/granola', async (req, res) => {
  const { title, creator, attendees, content, datetime } = req.body;

  // Validate webhook (use HMAC or shared secret)
  // if (!verifyHmac(req)) return res.status(401).send('Unauthorized');

  console.log(`Meeting received: ${title} (${datetime})`);

  // Extract action items
  const actionItems = content
    .split('\n')
    .filter(line => line.match(/^- \[ \]/))
    .map(line => line.replace('- [ ] ', ''));

  // Route based on meeting type
  const isExternal = attendees.some(a => !a.email?.endsWith('@company.com'));

  if (isExternal) {
    await handleExternalMeeting({ title, attendees, content, actionItems });
  } else {
    await handleInternalMeeting({ title, content, actionItems });
  }

  res.status(200).json({ processed: true, actions: actionItems.length });
});

async function handleExternalMeeting({ title, attendees, content, actionItems }) {
  // CRM update, follow-up email draft, Slack #sales notification
  console.log(`External meeting: ${title}, ${actionItems.length} action items`);
}

async function handleInternalMeeting({ title, content, actionItems }) {
  // Linear tasks, Notion archive, Slack #team notification
  console.log(`Internal meeting: ${title}, ${actionItems.length} action items`);
}

app.listen(3000, () => console.log('Granola webhook handler running on :3000'));

Python FastAPI handler:

from fastapi import FastAPI, Request
import re

app = FastAPI()

@app.post("/webhooks/granola")
async def handle_granola_event(request: Request):
    data = await request.json()
    title = data.get("title", "Untitled")
    content = data.get("content", "")
    attendees = data.get("attendees", [])

    # Extract action items
    actions = re.findall(r"- \[ \] (.+)", content)

    # Route by attendee type
    external = [a for a in attendees if not a.get("email", "").endswith("@company.com")]

    if external:
        # Process external meeting
        await process_external(title, actions, external)
    else:
        await process_internal(title, actions)

    return {"processed": True, "action_count": len(actions)}

Step 5 — Processing Patterns

Pattern	When to Use	Implementation
Immediate	Time-sensitive follow-ups	Direct Zapier actions, ~2 min latency
Batch	Reduce noise, aggregate	Queue to SQS/Redis, process every 15 min
Conditional	Route by meeting type	Zapier Paths or custom webhook with routing logic
Idempotent	Prevent duplicate processing	Store processed note IDs, skip duplicates

Step 6 — Error Handling and Retry

Zapier handles retries automatically for failed actions. For custom webhooks:

// Implement idempotency
const processedNotes = new Set(); // Use Redis/DB in production

app.post('/webhooks/granola', async (req, res) => {
  const noteId = `${req.body.title}-${req.body.datetime}`;

  if (processedNotes.has(noteId)) {
    return res.status(200).json({ status: 'already_processed' });
  }

  processedNotes.add(noteId);
  // ... process the event
});

Output

Zapier triggers configured for target folders
Event filtering routing meetings by type
Custom webhook handler processing events
Idempotency preventing duplicate processing

Error Handling

Error	Cause	Fix
Trigger not firing	Wrong folder name in Zapier	Verify folder name matches exactly (case-sensitive)
Empty note_content	Note still processing when trigger fires	Add 2-minute Delay step before processing actions
Duplicate events	Zapier retry on timeout	Implement idempotency with note ID deduplication
Webhook timeout	Handler takes > 30s	Return 200 immediately, process async
Missing attendees	Calendar event has no attendee list	No fix — attendees come from calendar event data
