Webhooks let apps communicate instantly. Instead of checking for updates, they send notifications when something happens.

How Webhooks Work

1. An event occurs (e.g., a user signs up).
2. The app sends an HTTP POST request to a specific URL.
3. The receiving app processes the data.

When to Use Webhooks

• Payments: Get notified when a payment is made.
• CRM updates: Sync customer data instantly.
• GitHub commits: Trigger actions when code is pushed.
• Chat notifications: Send messages based on events.

Setting Up a Webhook

1. Choose an Event

Select an event that triggers a webhook, like a payment success.

2. Create a Webhook URL

Set up a simple Express.js server:

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

app.post('/webhook', (req, res) => {
    console.log('Received:', req.body);
    res.sendStatus(200);
});

app.listen(3000, () => console.log('Server running on port 3000'));

3. Register the Webhook

Enter your webhook URL in the sending app’s settings.

4. Handle the Data

Make sure your app processes incoming data properly and securely.

Testing Webhooks

Try these tools:

• Postman: Send test HTTP requests.
• Webhook.site: Inspect webhook data.
• Ngrok: Test webhooks locally.

Webhooks simplify automation and app integration. Set them up and streamline your workflows!
