Quick Guide to Implementing Webhooks in Deadline Funnel

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

The Lowdown on Deadline Funnel and Webhooks

Deadline Funnel is your go-to for creating urgency in marketing campaigns, and webhooks are the secret sauce for keeping your app in sync with all the action. They're like little messengers that ping your app whenever something interesting happens in Deadline Funnel. Pretty neat, right?

Getting Your API Ducks in a Row

First things first, let's get you set up with the Deadline Funnel API:

1. Head over to your Deadline Funnel dashboard
2. Navigate to the API section
3. Generate your API key (keep it safe, it's like your secret handshake)

Here's a quick snippet to get you authenticated:

const axios = require('axios');

const apiKey = 'your_api_key_here';
const baseURL = 'https://app.deadlinefunnel.com/api/v1';

const api = axios.create({
  baseURL,
  headers: { 'Authorization': `Bearer ${apiKey}` }
});

Webhook Endpoints: Where the Magic Happens

Deadline Funnel offers a bunch of webhook events. Here are the most common ones you'll probably use:

• funnel.created
• funnel.updated
• lead.added
• lead.updated

The webhook payload will hit your endpoint with all the juicy details. Speaking of endpoints...

Setting Up Your Webhook Receiver

Let's whip up a quick Express server to catch those webhooks:

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

app.use(express.json());

app.post('/webhooks/deadline-funnel', (req, res) => {
  const event = req.body;
  console.log('Received webhook:', event);
  // Handle the event here
  res.sendStatus(200);
});

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

Trust, but Verify

Always verify your webhooks! It's like checking ID at the door. Here's how:

const crypto = require('crypto');

function verifyWebhookSignature(payload, signature, secret) {
  const hmac = crypto.createHmac('sha256', secret);
  const digest = hmac.update(JSON.stringify(payload)).digest('hex');
  return crypto.timingSafeEqual(Buffer.from(signature), Buffer.from(digest));
}

app.post('/webhooks/deadline-funnel', (req, res) => {
  const signature = req.headers['x-df-signature'];
  if (!verifyWebhookSignature(req.body, signature, 'your_webhook_secret')) {
    return res.sendStatus(401);
  }
  // Process the webhook...
});

Handling the Goods

Now that you've got the webhook data, it's time to do something cool with it:

app.post('/webhooks/deadline-funnel', (req, res) => {
  const { event, data } = req.body;
  
  switch (event) {
    case 'lead.added':
      console.log(`New lead added: ${data.email}`);
      // Maybe add them to your mailing list?
      break;
    case 'funnel.updated':
      console.log(`Funnel ${data.id} was updated`);
      // Sync the changes with your database
      break;
    // Handle other events...
  }
  
  res.sendStatus(200);
});

When Things Go Sideways

Webhooks can fail. It happens to the best of us. Here's a simple retry mechanism:

const MAX_RETRIES = 3;

async function processWebhook(event, retries = 0) {
  try {
    // Your webhook processing logic here
  } catch (error) {
    if (retries < MAX_RETRIES) {
      console.log(`Retrying webhook processing (${retries + 1}/${MAX_RETRIES})`);
      await new Promise(resolve => setTimeout(resolve, 1000 * (retries + 1)));
      return processWebhook(event, retries + 1);
    }
    console.error('Max retries reached. Webhook processing failed:', error);
  }
}

Taking It for a Spin

Before you go live, test your webhook integration. Deadline Funnel provides a testing tool in their dashboard. Use it!

For local testing, you can create a mock webhook:

const mockWebhook = {
  event: 'lead.added',
  data: {
    email: '[email protected]',
    funnel_id: '123456'
  }
};

// Simulate a webhook
axios.post('http://localhost:3000/webhooks/deadline-funnel', mockWebhook);

Scaling Up

If you're expecting a ton of webhooks, consider using a queue like Redis or RabbitMQ to process them asynchronously. Your server will thank you!

Wrapping Up

And there you have it! You're now armed and ready to implement webhooks with Deadline Funnel like a pro. Remember, webhooks are your friends – they keep your app in the loop and your users happy with real-time updates.
