Quick Guide to Implementing Webhooks in Jobber

Aug 13, 2024 • 7 minute read

Hey there, fellow JavaScript dev! Ready to supercharge your Jobber integration with some webhook magic? Let's dive right in and get those real-time updates flowing!

Introduction

Webhooks are like the cool kids of the API world – they don't wait around for you to ask for updates, they proactively ping you when something interesting happens. In Jobber, webhooks are your ticket to building responsive, user-facing integrations that stay in sync without constant polling. Trust me, your users (and your servers) will thank you.

Prerequisites

Before we jump into the code, make sure you've got:

Jobber API access (duh!)
A Node.js environment set up and ready to roll
A basic grasp of RESTful APIs (but you're a JS dev, so I'm sure you've got this covered)

Setting Up Webhooks

First things first, let's get that webhook subscription set up. It's as easy as pie – just a quick POST request to Jobber's API, and you're in business.

const axios = require('axios');

async function createWebhook() {
  try {
    const response = await axios.post('https://api.getjobber.com/api/webhooks', {
      url: 'https://your-awesome-app.com/webhook',
      event_types: ['job.created', 'job.updated']
    }, {
      headers: {
        'X-API-VERSION': '2023-03-01',
        'Authorization': 'Bearer YOUR_ACCESS_TOKEN'
      }
    });
    console.log('Webhook created:', response.data);
  } catch (error) {
    console.error('Error creating webhook:', error.response.data);
  }
}

createWebhook();

Boom! You've just created a webhook subscription. Jobber will now notify you whenever a job is created or updated.

Handling Webhook Events

Now that Jobber's ready to talk, let's set up our end to listen. We'll use Express.js for this example, but feel free to use your framework of choice.

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

app.use(express.json());

app.post('/webhook', (req, res) => {
  const signature = req.headers['x-jobber-signature'];
  const payload = JSON.stringify(req.body);
  const expectedSignature = crypto
    .createHmac('sha256', 'YOUR_WEBHOOK_SECRET')
    .update(payload)
    .digest('hex');

  if (signature !== expectedSignature) {
    return res.status(401).send('Invalid signature');
  }

  // Process the webhook payload
  console.log('Received webhook:', req.body);

  res.sendStatus(200);
});

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

Processing Webhook Data

Now that we're receiving events, let's do something useful with them!

app.post('/webhook', (req, res) => {
  // ... signature verification code ...

  const { event_type, payload } = req.body;

  switch (event_type) {
    case 'job.created':
      console.log('New job created:', payload.job.id);
      // Add your job creation logic here
      break;
    case 'job.updated':
      console.log('Job updated:', payload.job.id);
      // Add your job update logic here
      break;
    default:
      console.log('Unhandled event type:', event_type);
  }

  res.sendStatus(200);
});

Error Handling and Retries

Jobber's got your back with automatic retries, but it's up to you to handle errors gracefully. Here's how to keep things smooth:

app.post('/webhook', async (req, res) => {
  try {
    // ... signature verification and event processing ...

    // All good? Let Jobber know!
    res.sendStatus(200);
  } catch (error) {
    console.error('Error processing webhook:', error);
    // Something went wrong? Tell Jobber to retry later
    res.status(500).send('Internal server error');
  }
});

Testing Webhooks

Want to make sure everything's working without waiting for real events? Jobber's got you covered with their webhook testing tools. Here's a quick curl command to simulate an event:

curl -X POST https://your-awesome-app.com/webhook \
  -H "Content-Type: application/json" \
  -H "X-Jobber-Signature: YOUR_TEST_SIGNATURE" \
  -d '{"event_type": "job.created", "payload": {"job": {"id": 123}}}'

Best Practices

To keep your webhook implementation top-notch:

Always verify signatures to ensure requests are legit.
Implement idempotency to handle potential duplicate events.
Set up monitoring and logging – trust me, future you will be grateful.

Conclusion

And there you have it! You're now ready to build some killer user-facing integrations with Jobber webhooks. Remember, webhooks are all about real-time responsiveness, so get creative and build something awesome!
