Quick Guide to Implementing Webhooks in bexio

Aug 18, 2024 • 7 minute read

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

Introduction

Webhooks are like the cool kids of the API world - they notify your app instantly when something interesting happens in bexio. No more constant polling or refreshing. We'll be using bexio's API to set these up, so buckle up!

Prerequisites

Before we start, make sure you've got:

Your bexio API credentials (you rockstar, you)
A Node.js environment (because, duh, we're JS devs)
A basic grasp of RESTful APIs and webhooks (but don't sweat it if you're a bit rusty)

Setting Up the Webhook Endpoint

First things first, let's create a simple Express server to catch those webhook events:

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

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

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

Boom! You've got a basic webhook receiver up and running. Easy peasy, right?

Registering the Webhook with bexio API

Now, let's tell bexio where to send those juicy updates. We'll use axios because, well, it's awesome:

const axios = require('axios');

async function registerWebhook() {
  try {
    const response = await axios.post('https://api.bexio.com/2.0/webhooks', {
      url: 'https://your-app.com/webhook',
      events: ['contact.created', 'invoice.created'],
    }, {
      headers: { 'Authorization': 'Bearer YOUR_ACCESS_TOKEN' }
    });
    console.log('Webhook registered:', response.data);
  } catch (error) {
    console.error('Error registering webhook:', error.response.data);
  }
}

registerWebhook();

Replace 'https://your-app.com/webhook' with your actual endpoint URL, and don't forget to swap out YOUR_ACCESS_TOKEN with your real token!

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, payload } = req.body;
  
  switch(event) {
    case 'contact.created':
      handleNewContact(payload);
      break;
    case 'invoice.created':
      handleNewInvoice(payload);
      break;
    default:
      console.log('Unhandled event:', event);
  }
  
  res.sendStatus(200);
});

function handleNewContact(contact) {
  console.log('New contact created:', contact);
  // Do something awesome with the new contact data
}

function handleNewInvoice(invoice) {
  console.log('New invoice created:', invoice);
  // Maybe send a notification or update your database
}

Managing Webhook Subscriptions

Want to see what webhooks you've got? Update 'em? Delete 'em? We've got you covered:

// List webhooks
async function listWebhooks() {
  const response = await axios.get('https://api.bexio.com/2.0/webhooks', {
    headers: { 'Authorization': 'Bearer YOUR_ACCESS_TOKEN' }
  });
  console.log('Active webhooks:', response.data);
}

// Update a webhook
async function updateWebhook(webhookId, newConfig) {
  const response = await axios.put(`https://api.bexio.com/2.0/webhooks/${webhookId}`, newConfig, {
    headers: { 'Authorization': 'Bearer YOUR_ACCESS_TOKEN' }
  });
  console.log('Updated webhook:', response.data);
}

// Delete a webhook
async function deleteWebhook(webhookId) {
  await axios.delete(`https://api.bexio.com/2.0/webhooks/${webhookId}`, {
    headers: { 'Authorization': 'Bearer YOUR_ACCESS_TOKEN' }
  });
  console.log('Webhook deleted');
}

Error Handling and Best Practices

Listen up, because this is important:

Always respond to webhooks quickly (with a 200 status)
Implement retry logic for failed deliveries
Log everything - trust me, future you will thank present you

Here's a quick example of retry logic:

const MAX_RETRIES = 3;

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

Testing Webhooks

Before you go live, give your webhooks a good workout:

Use bexio's webhook testing tools (if they have any - check their docs!)
Set up a local tunnel with ngrok for testing your local environment

Conclusion

And there you have it! You're now a bexio webhook wizard. Remember, with great power comes great responsibility - use these webhooks wisely and watch your integration come alive with real-time goodness!
