Handling Webhook Data: Code Implementation

Once your webhook endpoint is established, the next step involves handling webhook data efficiently. This process includes receiving, processing, and responding to the webhook events. Here’s an example of code implementation using Express.js:

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

app.post('/webhook-endpoint', (req, res) => {
    const eventData = req.body;  // Retrieving webhook data

    // Process the received webhook data
    console.log('Received webhook:', eventData);

    // Send a response back to indicate successful handling
    res.status(200).send('Webhook received!');
});

// Start the server
app.listen(3000, () => {
    console.log('Server is listening on port 3000');
});

This code snippet demonstrates a basic implementation for receiving webhook data. Ensure that your application can handle incoming payloads efficiently, using techniques such as message queues for bursts of events.
