Quick Guide to Implementing Webhooks in Ticket Tailor

Hey there, fellow JavaScript aficionado! Ready to supercharge your Ticket Tailor integration with some real-time goodness? Let's dive into the world of webhooks and get you up and running in no time.

Prerequisites

Before we jump in, make sure you've got:

• Your Ticket Tailor API key (you know where to find that, right?)
• A Node.js environment (because, let's face it, who doesn't these days?)
• A basic grasp of Express.js (but you're a pro, so I'm sure you've got this covered)

Setting Up Webhooks

First things first, let's create a webhook using the Ticket Tailor API. It's as easy as sending a POST request:

const axios = require('axios');

const createWebhook = async () => {
  try {
    const response = await axios.post('https://api.tickettailor.com/v1/webhooks', {
      url: 'https://your-awesome-app.com/webhook',
      events: ['ticket.created', 'order.completed']
    }, {
      headers: {
        'Authorization': `Bearer ${YOUR_API_KEY}`,
        'Content-Type': 'application/json'
      }
    });
    console.log('Webhook created:', response.data);
  } catch (error) {
    console.error('Error creating webhook:', error);
  }
};

createWebhook();

Boom! You've just set up your webhook. Easy peasy, right?

Handling Webhook Events

Now, let's set up an endpoint to catch those juicy webhook payloads:

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

app.post('/webhook', express.json(), (req, res) => {
  const event = req.body;
  // We'll handle the event here in a bit
  res.sendStatus(200);
});

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

Verifying Webhook Signatures

Security first! Let's make sure these webhooks are legit:

const crypto = require('crypto');

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

Processing Webhook Data

Time to handle those events like a boss:

app.post('/webhook', express.json(), (req, res) => {
  const event = req.body;
  
  if (!verifySignature(event, req.headers['x-tt-signature'])) {
    return res.sendStatus(401);
  }

  switch (event.type) {
    case 'ticket.created':
      console.log('New ticket created:', event.data.id);
      // Do something awesome with the new ticket
      break;
    case 'order.completed':
      console.log('Order completed:', event.data.id);
      // Maybe send a confirmation email?
      break;
    default:
      console.log('Unhandled event type:', event.type);
  }

  res.sendStatus(200);
});

Error Handling and Retry Mechanism

Sometimes things go wrong. No worries, we've got your back:

const handleWebhook = async (event) => {
  const maxRetries = 3;
  let retries = 0;

  while (retries < maxRetries) {
    try {
      // Process the event
      return;
    } catch (error) {
      console.error(`Error processing webhook (attempt ${retries + 1}):`, error);
      retries++;
      await new Promise(resolve => setTimeout(resolve, 1000 * retries));
    }
  }

  console.error('Max retries reached. Webhook processing failed.');
};

Testing Webhooks

Ticket Tailor's got a nifty webhook testing tool, but nothing beats a good ol' console.log for debugging:

app.post('/webhook', express.json(), (req, res) => {
  console.log('Received webhook:', JSON.stringify(req.body, null, 2));
  // Rest of your webhook handling code
});

Scaling Considerations

Handling a tsunami of events? Consider implementing a queue system like RabbitMQ or Redis. But hey, that's a topic for another day!
