# Miro Deploy Integration

## Overview

Deploy Miro REST API v2 integrations to popular platforms with proper OAuth 2.0 token management, webhook endpoint setup, and health monitoring.

## Prerequisites

- Miro app configured with production OAuth credentials
- Access token with required scopes
- Platform CLI installed (vercel, fly, or gcloud)

## Vercel Deployment

### Environment Variables

```bash
# Add Miro secrets to Vercel
vercel env add MIRO_CLIENT_ID production
vercel env add MIRO_CLIENT_SECRET production
vercel env add MIRO_ACCESS_TOKEN production
vercel env add MIRO_WEBHOOK_SECRET production
```

### API Route: Webhook Handler

```typescript
// api/webhooks/miro.ts (Vercel serverless function)
import crypto from 'crypto';

export const config = { api: { bodyParser: false } };

export default async function handler(req, res) {
  if (req.method !== 'POST') return res.status(405).end();

  const chunks: Buffer[] = [];
  for await (const chunk of req) chunks.push(chunk);
  const rawBody = Buffer.concat(chunks);

  // Verify Miro webhook signature
  const signature = req.headers['x-miro-signature'] as string;
  const expected = crypto.createHmac('sha256', process.env.MIRO_WEBHOOK_SECRET!)
    .update(rawBody).digest('hex');

  if (!signature || !crypto.timingSafeEqual(Buffer.from(signature), Buffer.from(expected))) {
    return res.status(401).json({ error: 'Invalid signature' });
  }

  const event = JSON.parse(rawBody.toString());

  // Handle board subscription events
  switch (event.event) {
    case 'board_subscription_changed':
      console.log(`Board ${event.boardId}: item ${event.item?.type} ${event.type}`);
      break;
  }

  res.status(200).json({ received: true });
}
```

### API Route: OAuth Callback

```typescript
// api/auth/miro/callback.ts
export default async function handler(req, res) {
  const { code } = req.query;

  const tokenResponse = await fetch('https://api.miro.com/v1/oauth/token', {
    method: 'POST',
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
    body: new URLSearchParams({
      grant_type: 'authorization_code',
      client_id: process.env.MIRO_CLIENT_ID!,
      client_secret: process.env.MIRO_CLIENT_SECRET!,
      code: code as string,
      redirect_uri: `${process.env.VERCEL_URL}/api/auth/miro/callback`,
    }),
  });

  const tokens = await tokenResponse.json();
  // Store tokens securely (database, not env vars)
  // tokens.access_token, tokens.refresh_token, tokens.expires_in (3599s)

  res.redirect('/dashboard?connected=miro');
}
```

### vercel.json

```json
{
  "functions": {
    "api/webhooks/miro.ts": { "maxDuration": 10 },
    "api/auth/miro/callback.ts": { "maxDuration": 10 }
  },
  "headers": [
    {
      "source": "/api/health",
      "headers": [{ "key": "Cache-Control", "value": "no-store" }]
    }
  ]
}
```

## Fly.io Deployment

### fly.toml

```toml
app = "my-miro-integration"
primary_region = "iad"

[env]
  NODE_ENV = "production"
  MIRO_API_BASE = "https://api.miro.com/v2"

[http_service]
  internal_port = 3000
  force_https = true
  auto_stop_machines = "suspend"
  auto_start_machines = true
  min_machines_running = 1        # Keep 1 running for webhook delivery

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

### Deploy

```bash
# Set secrets
fly secrets set MIRO_CLIENT_ID=your_client_id
fly secrets set MIRO_CLIENT_SECRET=your_client_secret
fly secrets set MIRO_ACCESS_TOKEN=your_token
fly secrets set MIRO_WEBHOOK_SECRET=your_webhook_secret

# Deploy
fly deploy

# Verify health
fly ssh console -C "curl -s http://localhost:3000/health | jq '.miro'"
```

## Google Cloud Run

### Deploy Script

```bash
#!/bin/bash
set -euo pipefail

PROJECT_ID="${GOOGLE_CLOUD_PROJECT}"
SERVICE_NAME="miro-integration"
REGION="us-central1"

# Store secrets in Secret Manager
echo -n "$MIRO_CLIENT_SECRET" | gcloud secrets create miro-client-secret --data-file=-
echo -n "$MIRO_ACCESS_TOKEN" | gcloud secrets create miro-access-token --data-file=-
echo -n "$MIRO_WEBHOOK_SECRET" | gcloud secrets create miro-webhook-secret --data-file=-

# Build and deploy
gcloud run deploy $SERVICE_NAME \
  --source . \
  --region $REGION \
  --platform managed \
  --allow-unauthenticated \
  --min-instances 1 \
  --set-env-vars "MIRO_CLIENT_ID=$MIRO_CLIENT_ID,MIRO_API_BASE=https://api.miro.com/v2" \
  --set-secrets "MIRO_CLIENT_SECRET=miro-client-secret:latest,MIRO_ACCESS_TOKEN=miro-access-token:latest,MIRO_WEBHOOK_SECRET=miro-webhook-secret:latest"
```

## Health Check Endpoint

```typescript
// src/health.ts — works on any platform
export async function healthCheck(): Promise<HealthResponse> {
  const checks: Record<string, unknown> = {};

  // Miro API connectivity
  const start = Date.now();
  try {
    const response = await fetch('https://api.miro.com/v2/boards?limit=1', {
      headers: { 'Authorization': `Bearer ${process.env.MIRO_ACCESS_TOKEN}` },
      signal: AbortSignal.timeout(5000),
    });

    checks.miro = {
      status: response.ok ? 'healthy' : 'degraded',
      latencyMs: Date.now() - start,
      rateLimitRemaining: response.headers.get('X-RateLimit-Remaining'),
      httpStatus: response.status,
    };
  } catch (err) {
    checks.miro = { status: 'unhealthy', error: err.message };
  }

  return {
    status: Object.values(checks).every((c: any) => c.status === 'healthy') ? 'healthy' : 'degraded',
    services: checks,
    timestamp: new Date().toISOString(),
  };
}
```

## Webhook URL Registration via API

After deploying, register your webhook endpoint programmatically:

```typescript
// Register board subscription webhook
// POST https://api.miro.com/v2-experimental/webhooks/board_subscriptions
const subscription = await fetch(
  'https://api.miro.com/v2-experimental/webhooks/board_subscriptions',
  {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.MIRO_ACCESS_TOKEN}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      boardId: 'your-board-id',
      callbackUrl: 'https://your-app.com/api/webhooks/miro',
      status: 'enabled',
    }),
  }
);
```

## Error Handling

| Issue | Cause | Solution |
|-------|-------|----------|
| Webhook delivery fails | URL not HTTPS | Ensure force_https is enabled |
| Token expires in production | No refresh logic | Implement scheduled token refresh |
| Cold start misses webhook | Min instances = 0 | Set min_machines_running = 1 |
| Secret rotation breaks deploy | Old secret cached | Restart service after secret update |
