Figma Webhooks & Events

Overview

Figma Webhooks V2 push real-time notifications when files change, comments are posted, or libraries are published. Webhooks can be scoped to teams, projects, or individual files. Authentication uses a passcode echoed back in each payload.

Prerequisites

• HTTPS endpoint accessible from the internet
• FIGMA_PAT with webhooks:write scope
• Team ID (from Figma URL: figma.com/files/team/<TEAM_ID>/...)

Instructions

Step 1: Create a Webhook

# POST /v2/webhooks -- requires webhooks:write scope
curl -X POST https://api.figma.com/v2/webhooks \
  -H "X-Figma-Token: ${FIGMA_PAT}" \
  -H "Content-Type: application/json" \
  -d '{
    "event_type": "FILE_UPDATE",
    "team_id": "123456789",
    "endpoint": "https://yourapp.com/webhooks/figma",
    "passcode": "your-secret-passcode",
    "description": "Sync design tokens on file update"
  }'

# Response:
# { "id": "wh_abc123", "event_type": "FILE_UPDATE", "status": "ACTIVE", ... }

Available event types:

Event Type	Trigger	Payload Contains
FILE_UPDATE	File saved to version history	file_key, file_name, timestamp
FILE_DELETE	File deleted	file_key, file_name
FILE_VERSION_UPDATE	Named version created	file_key, version_id, label
FILE_COMMENT	Comment added	file_key, comment, comment_id
LIBRARY_PUBLISH	Library published	file_key, description, variables

Step 2: Handle Webhook Events

import express from 'express';
import crypto from 'crypto';

const app = express();
app.use(express.json());

// Figma webhook payload types
interface FigmaWebhookBase {
  event_type: string;
  passcode: string;
  timestamp: string;
  webhook_id: string;
}

interface FileUpdateEvent extends FigmaWebhookBase {
  event_type: 'FILE_UPDATE';
  file_key: string;
  file_name: string;
  triggered_by: { id: string; handle: string };
}

interface FileCommentEvent extends FigmaWebhookBase {
  event_type: 'FILE_COMMENT';
  file_key: string;
  file_name: string;
  comment: Array<{ text: string }>;
  comment_id: string;
  triggered_by: { id: string; handle: string };
}

interface LibraryPublishEvent extends FigmaWebhookBase {
  event_type: 'LIBRARY_PUBLISH';
  file_key: string;
  file_name: string;
  description: string;
  triggered_by: { id: string; handle: string };
}

type FigmaWebhookEvent = FileUpdateEvent | FileCommentEvent | LibraryPublishEvent;

app.post('/webhooks/figma', (req, res) => {
  const event: FigmaWebhookEvent = req.body;

  // 1. Verify passcode (timing-safe)
  const expected = process.env.FIGMA_WEBHOOK_PASSCODE!;
  if (event.passcode.length !== expected.length ||
      !crypto.timingSafeEqual(Buffer.from(event.passcode), Buffer.from(expected))) {
    return res.status(401).json({ error: 'Invalid passcode' });
  }

  // 2. Respond quickly (Figma expects 200 within seconds)
  res.status(200).json({ received: true });

  // 3. Process async
  processEvent(event).catch(err =>
    console.error(`Failed to process ${event.event_type}:`, err)
  );
});

async function processEvent(event: FigmaWebhookEvent) {
  switch (event.event_type) {
    case 'FILE_UPDATE':
      console.log(`File updated: ${event.file_name} by ${event.triggered_by.handle}`);
      // Re-extract design tokens, invalidate cache, notify Slack
      await syncDesignTokens(event.file_key);
      break;

    case 'FILE_COMMENT':
      console.log(`Comment on ${event.file_name}: ${event.comment[0]?.text}`);
      // Forward to Slack, create Jira ticket, etc.
      break;

    case 'LIBRARY_PUBLISH':
      console.log(`Library published: ${event.file_name}`);
      // Trigger downstream rebuilds
      await triggerTokenRebuild(event.file_key);
      break;
  }
}

Step 3: Manage Webhooks

const FIGMA_API = 'https://api.figma.com';

// List all webhooks for a team
async function listWebhooks(teamId: string) {
  const res = await fetch(`${FIGMA_API}/v2/webhooks?team_id=${teamId}`, {
    headers: { 'X-Figma-Token': process.env.FIGMA_PAT! },
  });
  return res.json(); // { webhooks: [...] }
}

// Delete a webhook
async function deleteWebhook(webhookId: string) {
  await fetch(`${FIGMA_API}/v2/webhooks/${webhookId}`, {
    method: 'DELETE',
    headers: { 'X-Figma-Token': process.env.FIGMA_PAT! },
  });
}

// Update a webhook (e.g., change endpoint)
async function updateWebhook(webhookId: string, updates: Record<string, any>) {
  const res = await fetch(`${FIGMA_API}/v2/webhooks/${webhookId}`, {
    method: 'PUT',
    headers: {
      'X-Figma-Token': process.env.FIGMA_PAT!,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify(updates),
  });
  return res.json();
}

Step 4: Idempotency for Duplicate Events

// Figma may deliver the same event multiple times
const processedEvents = new Set<string>();

function deduplicateEvent(event: FigmaWebhookEvent): boolean {
  const key = `${event.webhook_id}:${event.timestamp}`;
  if (processedEvents.has(key)) {
    console.log(`Duplicate event skipped: ${key}`);
    return false;
  }
  processedEvents.add(key);
  // Clean up old entries (keep last 1000)
  if (processedEvents.size > 1000) {
    const oldest = Array.from(processedEvents).slice(0, 500);
    oldest.forEach(k => processedEvents.delete(k));
  }
  return true;
}

Output

• Webhook created and receiving Figma events
• Passcode verification on every incoming request
• Event handlers for FILE_UPDATE, FILE_COMMENT, LIBRARY_PUBLISH
• Idempotency preventing duplicate processing

Error Handling

Issue	Cause	Solution
Webhook not firing	Endpoint not HTTPS	Figma requires TLS
Invalid passcode	Wrong secret configured	Verify passcode in webhook creation
Webhook status PAUSED	Too many delivery failures	Fix endpoint, then recreate webhook
Missing triggered_by	Older event format	Check webhook V2 vs V1

Examples

Test Webhook Locally

# Use ngrok to expose local server
ngrok http 3000

# Create webhook pointing to ngrok URL
curl -X POST https://api.figma.com/v2/webhooks \
  -H "X-Figma-Token: ${FIGMA_PAT}" \
  -H "Content-Type: application/json" \
  -d '{
    "event_type": "FILE_UPDATE",
    "team_id": "YOUR_TEAM_ID",
    "endpoint": "https://YOUR-NGROK.ngrok.io/webhooks/figma",
    "passcode": "test-passcode"
  }'
