Overview

Webhooks allow you to receive real-time notifications when events occur in your BoostGPT project.

​
Available Events

  • bot.created - New bot created
  • bot.updated - Bot settings changed
  • bot.deleted - Bot deleted
  • chat.message - New chat message sent
  • subscriber.added - New subscriber captured
  • training.added - Training data added

​
Setup Webhook

1

Create Endpoint

Create an endpoint that accepts POST requests
2

Add Webhook in Dashboard

Go to Settings -> Webhooks -> Add Webhook
3

Enter URL

Provide your endpoint URL (must be HTTPS)
4

Select Events

Choose which events to receive

​
Webhook Payload

All webhooks send JSON payloads: 
{
  "event": "chat.message",
  "timestamp": "2025-01-01T12:00:00Z",
  "project_id": "proj_123",
  "data": {
    "bot_id": "bot_456",
    "message": "Hello",
    "response": "Hi! How can I help?"
  }
}

​
Example Endpoint

​
Express.js

import express from 'express';

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

app.post('/webhooks/boostgpt', (req, res) => {
  const { event, data } = req.body;

  console.log('Received event:', event);

  switch (event) {
    case 'chat.message':
      console.log('New chat:', data.message);
      break;
    case 'subscriber.added':
      console.log('New subscriber:', data.email);
      break;
    default:
      console.log('Unknown event:', event);
  }

  // Acknowledge receipt
  res.status(200).json({ received: true });
});

app.listen(3000);

​
Next.js API Route

// pages/api/webhooks/boostgpt.js

export default async function handler(req, res) {
  if (req.method !== 'POST') {
    return res.status(405).json({ error: 'Method not allowed' });
  }

  const { event, data } = req.body;

  // Handle event
  if (event === 'subscriber.added') {
    // Add to email list
    await addToMailchimp(data.email);
  }

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

​
Verify Webhook Signature

Verify webhooks are from BoostGPT: 
import crypto from 'crypto';

function verifySignature(payload, signature, secret) {
  const hash = crypto
    .createHmac('sha256', secret)
    .update(JSON.stringify(payload))
    .digest('hex');

  return hash === signature;
}

app.post('/webhooks/boostgpt', (req, res) => {
  const signature = req.headers['x-boostgpt-signature'];
  const secret = process.env.WEBHOOK_SECRET;

  if (!verifySignature(req.body, signature, secret)) {
    return res.status(401).json({ error: 'Invalid signature' });
  }

  // Process webhook
  res.status(200).json({ received: true });
});

​
Best Practices

  • Return 200 quickly - Don’t process long tasks in webhook handler
  • Use queues - Add events to a queue for async processing
  • Verify signatures - Always verify webhook authenticity
  • Handle retries - Respond with 200 to prevent retries
  • Log events - Keep logs for debugging

​
Testing Webhooks

Test locally using ngrok: 
# Start your local server
node server.js

# In another terminal, expose it
ngrok http 3000

# Use the ngrok URL in dashboard
https://abc123.ngrok.io/webhooks/boostgpt
