Lindy Deploy Integration

Overview

Lindy agents run on Lindy's managed infrastructure. Deployment focuses on your integration layer: webhook receivers, callback handlers, and application code that Lindy agents interact with via HTTP Request actions and webhook triggers.

Prerequisites

• Lindy agents configured and tested
• Application with webhook receiver endpoints
• Deployment platform (Vercel, Railway, Docker, AWS, GCP)
• Lindy API key and webhook secrets

Instructions

Step 1: Prepare Application for Deployment

// src/server.ts — Production-ready Lindy webhook receiver
import express from 'express';
import helmet from 'helmet';

const app = express();
app.use(helmet());
app.use(express.json({ limit: '1mb' }));

// Health check for load balancer
app.get('/health', (req, res) => {
  res.json({
    status: 'ok',
    timestamp: new Date().toISOString(),
    version: process.env.APP_VERSION || 'unknown',
  });
});

// Lindy webhook receiver with auth verification
app.post('/lindy/callback', (req, res) => {
  const auth = req.headers.authorization;
  if (auth !== `Bearer ${process.env.LINDY_CALLBACK_SECRET}`) {
    return res.status(401).json({ error: 'Unauthorized' });
  }

  // Respond immediately, process async
  res.json({ received: true });

  // Async processing
  processWebhook(req.body).catch(err => {
    console.error('Webhook processing error:', err);
  });
});

async function processWebhook(payload: any) {
  const { taskId, status, result } = payload;
  // Your business logic here
  console.log(`Task ${taskId}: ${status}`, result);
}

const PORT = process.env.PORT || 3000;
app.listen(PORT, () => console.log(`Listening on :${PORT}`));

Step 2: Docker Deployment

# Dockerfile
FROM node:20-alpine
WORKDIR /app
COPY package*.json ./
RUN npm ci --production
COPY dist/ ./dist/
EXPOSE 3000
ENV NODE_ENV=production
HEALTHCHECK --interval=30s --timeout=3s \
  CMD wget -qO- http://localhost:3000/health || exit 1
CMD ["node", "dist/server.js"]

# Build and run
docker build -t lindy-integration .
docker run -d \
  -p 3000:3000 \
  -e LINDY_CALLBACK_SECRET="$LINDY_CALLBACK_SECRET" \
  --name lindy-app \
  lindy-integration

Step 3: Vercel Deployment

# Install Vercel CLI
npm i -g vercel

# Set secrets
vercel secrets add lindy-callback-secret "$LINDY_CALLBACK_SECRET"

# Deploy
vercel --prod

// vercel.json
{
  "env": {
    "LINDY_CALLBACK_SECRET": "@lindy-callback-secret"
  }
}

Step 4: Update Lindy Agent Webhook URLs

After deployment, update all Lindy agents with production URLs:

1. In Lindy dashboard, open each agent with a webhook trigger

2. Navigate to the HTTP Request action (if agent calls your API)

3. Update URL from dev/staging to production:

   OLD: https://abc123.ngrok.io/lindy/callback
   NEW: https://api.yourapp.com/lindy/callback
   

4. For webhook triggers, callers need the Lindy-generated URL (unchanged)

5. Test with a sample webhook to verify end-to-end

Step 5: Post-Deploy Verification

#!/bin/bash
echo "=== Post-Deploy Verification ==="

PROD_URL="https://api.yourapp.com"

# Health check
echo "[1/3] Health check..."
curl -sf "$PROD_URL/health" | jq .

# Webhook endpoint reachable
echo "[2/3] Webhook endpoint..."
STATUS=$(curl -s -o /dev/null -w "%{http_code}" \
  -X POST "$PROD_URL/lindy/callback" \
  -H "Authorization: Bearer $LINDY_CALLBACK_SECRET" \
  -H "Content-Type: application/json" \
  -d '{"test": true}')
echo "Webhook endpoint: HTTP $STATUS (expect 200)"

# Trigger a test agent run
echo "[3/3] Agent trigger test..."
curl -s -X POST "https://public.lindy.ai/api/v1/webhooks/YOUR_ID" \
  -H "Authorization: Bearer $LINDY_TRIGGER_SECRET" \
  -H "Content-Type: application/json" \
  -d '{"event": "deploy.verify", "env": "production"}'
echo "Agent triggered — check Tasks tab in Lindy dashboard"

Step 6: Rollback Plan

# If deployment fails, rollback:
# Vercel
vercel rollback

# Docker
docker stop lindy-app
docker run -d --name lindy-app-rollback \
  -e LINDY_CALLBACK_SECRET="$LINDY_CALLBACK_SECRET" \
  lindy-integration:previous-tag

# Update Lindy agents back to previous URLs if needed

Output

Produce a deployment receipt with the release identifier, deployed callback URL, health-check result, authenticated and unauthenticated webhook outcomes, and the verified Lindy task ID. Keep the previous image or deployment revision and the corresponding rollback command with that receipt.

Examples

For a Vercel release, record the production URL, a GET /health 200 result, an unauthenticated callback 401 result, and a successful signed test event. If the signed callback returns 502, invoke the documented rollback before changing Lindy agent URLs or retrying the test.
