Quick Guide to Implementing Webhooks in Landingi

Introduction

Hey there, fellow Javascript devs! Ready to supercharge your Landingi integration with webhooks? You're in the right place. Webhooks are like the cool kids of real-time data transfer, and with Landingi's API, you'll be setting them up in no time. Let's dive in!

Prerequisites

Before we get our hands dirty, make sure you've got:

• A Landingi account with API access (duh!)
• Node.js installed and ready to roll
• Your favorite code editor (we won't judge)
• A basic grasp of RESTful APIs (but you knew that already, right?)

Setting Up Webhook Endpoints

First things first, let's create a simple Express server to handle those incoming webhooks. It's as easy as pie:

const express = require('express');
const app = express();
const PORT = 3000;

app.use(express.json());

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

app.listen(PORT, () => console.log(`Webhook server running on port ${PORT}`));

Boom! You've got a basic server ready to catch those webhooks.

Registering Webhooks with Landingi API

Now, let's tell Landingi where to send those juicy webhooks. We'll use axios to make this a breeze:

const axios = require('axios');

const registerWebhook = async () => {
  try {
    const response = await axios.post('https://api.landingi.com/v1/webhooks', {
      url: 'https://your-server.com/webhook',
      events: ['lead_generated', 'form_submitted']
    }, {
      headers: {
        'Authorization': 'Bearer YOUR_API_KEY'
      }
    });
    console.log('Webhook registered:', response.data);
  } catch (error) {
    console.error('Error registering webhook:', error.response.data);
  }
};

registerWebhook();

Just replace YOUR_API_KEY with your actual API key, and you're golden!

Handling Webhook Payloads

When those webhooks start rolling in, you'll want to handle them like a pro:

app.post('/webhook', (req, res) => {
  const { event, data } = req.body;
  
  switch(event) {
    case 'lead_generated':
      handleNewLead(data);
      break;
    case 'form_submitted':
      processFormSubmission(data);
      break;
    default:
      console.log('Unhandled event:', event);
  }
  
  res.sendStatus(200);
});

function handleNewLead(leadData) {
  // Your awesome lead handling logic here
}

function processFormSubmission(formData) {
  // Your brilliant form processing code here
}

Common Use Cases

Now that you've got the basics down, let's talk about some cool things you can do:

• Instantly notify your sales team when a hot lead comes in
• Automatically add new leads to your CRM
• Trigger email campaigns based on form submissions
• Update your dashboard in real-time with A/B test results

The sky's the limit, folks!

Error Handling and Retry Mechanisms

Sometimes things go wrong. No worries, we've got your back. Here's a simple retry mechanism:

const MAX_RETRIES = 3;

async function handleWebhookWithRetry(webhookData, retryCount = 0) {
  try {
    await processWebhook(webhookData);
  } catch (error) {
    if (retryCount < MAX_RETRIES) {
      console.log(`Retry attempt ${retryCount + 1}`);
      setTimeout(() => handleWebhookWithRetry(webhookData, retryCount + 1), 1000 * Math.pow(2, retryCount));
    } else {
      console.error('Max retries reached. Webhook processing failed.');
    }
  }
}

This little gem will retry failed webhook processing with exponential backoff. Neat, huh?

Testing and Debugging

Testing webhooks can be tricky, but fear not! Tools like ngrok or Webhook.site are your new best friends. And don't forget to log everything:

const winston = require('winston');

const logger = winston.createLogger({
  level: 'info',
  format: winston.format.json(),
  transports: [
    new winston.transports.File({ filename: 'webhook.log' })
  ]
});

app.post('/webhook', (req, res) => {
  logger.info('Webhook received', { body: req.body });
  // Your webhook handling code here
});

Best Practices

Before you go, here are some pro tips:

1. Always validate incoming webhooks (check those signatures!)
2. Use HTTPS for your webhook endpoints (security first, people!)
3. Process webhook payloads asynchronously to avoid timeouts
4. Implement proper error handling and logging
5. Scale your webhook infrastructure as your traffic grows

Conclusion

And there you have it, folks! You're now ready to implement webhooks like a boss. Remember, with great webhook power comes great responsibility. Use them wisely, and watch your Landingi integration soar to new heights!

Happy coding, and may your webhooks always find their target! 🚀
