Quick Guide to Implementing Webhooks in NeverBounce

Hey there, fellow Javascript devs! Ready to supercharge your NeverBounce integration with webhooks? Let's dive right in and get those real-time updates flowing!

Prerequisites

Before we start, make sure you've got:

• A NeverBounce account with an API key
• Node.js installed on your machine
• Your favorite code editor ready to roll

If you're comfortable with RESTful APIs, you're already ahead of the game!

Setting Up the Webhook Endpoint

First things first, let's create a simple Express server to handle our webhooks:

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

app.post('/webhook', (req, res) => {
  // We'll fill this in soon!
  console.log('Webhook received:', req.body);
  res.sendStatus(200);
});

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

Configuring Webhooks in NeverBounce

Now, hop over to your NeverBounce dashboard:

1. Navigate to the Webhooks section
2. Click "Add New Webhook"
3. Enter your endpoint URL (e.g., https://your-domain.com/webhook)
4. Select the events you want to trigger the webhook
5. Save and you're set!

Handling Webhook Payloads

Time to make our webhook endpoint smarter:

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

  switch (event) {
    case 'job_completed':
      handleJobCompleted(data);
      break;
    case 'job_failed':
      handleJobFailed(data);
      break;
    // Add more cases as needed
  }

  res.sendStatus(200);
});

function handleJobCompleted(data) {
  console.log('Job completed:', data.job_id);
  // Your logic here
}

function handleJobFailed(data) {
  console.log('Job failed:', data.job_id);
  // Your error handling logic
}

Implementing Retry Logic

For those pesky failed deliveries, let's add some retry logic:

const queue = require('better-queue');

const retryQueue = new queue(async (task, cb) => {
  try {
    await processWebhook(task);
    cb(null);
  } catch (error) {
    cb(error);
  }
}, { maxRetries: 3, retryDelay: 1000 });

app.post('/webhook', (req, res) => {
  retryQueue.push(req.body);
  res.sendStatus(200);
});

async function processWebhook(payload) {
  // Your webhook processing logic here
}

Error Handling and Logging

Don't forget to catch those errors and log important events:

const winston = require('winston');
const logger = winston.createLogger(/* your config here */);

app.post('/webhook', (req, res) => {
  try {
    // Process webhook
    logger.info('Webhook processed successfully', { payload: req.body });
  } catch (error) {
    logger.error('Error processing webhook', { error, payload: req.body });
  }
  res.sendStatus(200);
});

Testing Your Webhook Implementation

NeverBounce provides a handy test feature in the dashboard. Use it to simulate different events and make sure your implementation is rock-solid!

Best Practices

1. Secure your endpoint: Use HTTPS and consider adding authentication.
2. Respond quickly: Always return a 200 status ASAP, then process asynchronously.
3. Be idempotent: Handle duplicate webhooks gracefully.

Wrapping Up

And there you have it! You've just implemented webhooks for NeverBounce like a pro. Remember, this is just the beginning – feel free to expand and customize based on your specific needs.

Happy coding, and may your bounces be few and your deliveries many!
