Figma Deploy Integration

Overview

Deploy Figma webhook receivers and design API services to production platforms with proper secret management and health checks.

Prerequisites

• Figma PAT for production environment
• Platform CLI installed (vercel, fly, or gcloud)
• Application tested locally with Figma API

Instructions

Step 1: Vercel Deployment (Webhook Receiver)

# Store Figma secrets
vercel env add FIGMA_PAT production
vercel env add FIGMA_WEBHOOK_PASSCODE production

# Deploy
vercel --prod

// api/webhooks/figma.ts (Vercel serverless function)
import { NextRequest, NextResponse } from 'next/server';
import crypto from 'crypto';

export async function POST(req: NextRequest) {
  const payload = await req.json();

  // Verify passcode
  const expected = process.env.FIGMA_WEBHOOK_PASSCODE!;
  const received = payload.passcode || '';
  const a = Buffer.from(received);
  const b = Buffer.from(expected);
  // timingSafeEqual throws on length mismatch — guard first
  if (a.length !== b.length || !crypto.timingSafeEqual(a, b)) {
    return NextResponse.json({ error: 'Invalid passcode' }, { status: 401 });
  }

  // Process webhook event
  switch (payload.event_type) {
    case 'FILE_UPDATE':
      console.log(`File updated: ${payload.file_name} (${payload.file_key})`);
      // Trigger token re-sync, invalidate cache, etc.
      break;
    case 'FILE_COMMENT':
      console.log(`New comment on ${payload.file_name}`);
      break;
    case 'LIBRARY_PUBLISH':
      console.log(`Library published: ${payload.file_name}`);
      break;
  }

  return NextResponse.json({ received: true });
}

export const config = { maxDuration: 10 };

Step 2: Google Cloud Run (Design Token API)

FROM node:20-slim
WORKDIR /app
COPY package*.json ./
RUN npm ci --omit=dev
COPY dist/ ./dist/
ENV PORT=8080
CMD ["node", "dist/server.js"]

PROJECT_ID="${GOOGLE_CLOUD_PROJECT}"
SERVICE="figma-token-api"
REGION="us-central1"

# Store PAT in Secret Manager
echo -n "${FIGMA_PAT}" | gcloud secrets create figma-pat --data-file=-

# Build and deploy
gcloud builds submit --tag gcr.io/$PROJECT_ID/$SERVICE
gcloud run deploy $SERVICE \
  --image gcr.io/$PROJECT_ID/$SERVICE \
  --region $REGION \
  --platform managed \
  --set-secrets="FIGMA_PAT=figma-pat:latest" \
  --allow-unauthenticated \
  --max-instances=5 \
  --timeout=30s

Step 3: Fly.io (Persistent Webhook Service)

# fly.toml
app = "figma-webhook-service"
primary_region = "iad"

[env]
  NODE_ENV = "production"

[http_service]
  internal_port = 3000
  force_https = true
  auto_stop_machines = "suspend"
  auto_start_machines = true
  min_machines_running = 1

[[http_service.checks]]
  grace_period = "10s"
  interval = "30s"
  method = "GET"
  path = "/health"
  timeout = "5s"

fly secrets set FIGMA_PAT=figd_your-token
fly secrets set FIGMA_WEBHOOK_PASSCODE=your-passcode
fly deploy

Step 4: Health Check Endpoint

// src/health.ts -- works on any platform
import { figmaFetch } from './figma-client';

export async function healthHandler(req: Request): Promise<Response> {
  const start = Date.now();

  try {
    const res = await fetch('https://api.figma.com/v1/me', {
      headers: { 'X-Figma-Token': process.env.FIGMA_PAT! },
      signal: AbortSignal.timeout(5000),
    });

    return Response.json({
      status: res.ok ? 'healthy' : 'degraded',
      figma: {
        authenticated: res.ok,
        latencyMs: Date.now() - start,
      },
      timestamp: new Date().toISOString(),
    });
  } catch {
    return Response.json({
      status: 'unhealthy',
      figma: { authenticated: false, latencyMs: Date.now() - start },
    }, { status: 503 });
  }
}

Output

• Application deployed with Figma secrets configured
• Webhook endpoint receiving Figma events
• Health check validating Figma connectivity
• Platform-specific optimizations applied

Error Handling

Examples

Deploy the webhook receiver to Vercel (Step 1) and verify end-to-end:

vercel deploy --prod
curl -s -X POST https://figma-hooks.example.vercel.app/api/figma/webhook \
  -H 'Content-Type: application/json' \
  -d '{"event_type":"PING","passcode":"'"${WEBHOOK_PASSCODE}"'"}'
# 200 {"ok":true}

Then point Figma at it and watch a real event arrive:

POST /api/figma/webhook  200  event=FILE_UPDATE file=AbC123 triggered_by=mia.designer

Probe the deployed health endpoint (Step 4) — it checks Figma reachability, not just process-up:

curl -s https://figma-hooks.example.vercel.app/api/health | jq .
# {"status":"ok","figma_api":"reachable","uptime_s":86400}
