Quick Guide to Implementing Webhooks in Salesmate

Sep 15, 2024 • 6 minute read

Hey there, fellow Javascript devs! Ready to supercharge your Salesmate integration 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 you instantly when something interesting happens in Salesmate. No more constant polling or wasted API calls. We'll be using Salesmate's API to set these up, so buckle up!

Prerequisites

Before we start, make sure you've got:

A Salesmate account with API access (you're not still using the free tier, are you?)
Node.js environment (because, let's face it, who doesn't love Node?)
A basic grasp of RESTful APIs and webhooks (but you knew that already, right?)

Setting up the Webhook Endpoint

First things first, let's create a simple Express.js server to receive those juicy 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'));

Easy peasy, right? This little server is now ready to catch any webhooks Salesmate throws at it.

Registering the Webhook with Salesmate API

Now, let's tell Salesmate where to send those webhooks. We'll use the Salesmate API for this:

const axios = require('axios');

const registerWebhook = async () => {
  try {
    const response = await axios.post('https://api.salesmate.io/v3/webhooks', {
      url: 'https://your-server.com/webhook',
      events: ['deal.created', 'deal.updated'],
      isActive: true
    }, {
      headers: {
        'X-API-KEY': 'your-salesmate-api-key'
      }
    });
    console.log('Webhook registered:', response.data);
  } catch (error) {
    console.error('Error registering webhook:', error.response.data);
  }
};

registerWebhook();

Just replace 'your-server.com' with your actual server URL and 'your-salesmate-api-key' with your API key. Boom! You're registered.

Handling Webhook Events

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

app.post('/webhook', (req, res) => {
  const { event, payload } = req.body;
  
  switch(event) {
    case 'deal.created':
      console.log('New deal created:', payload.dealName);
      // Do something awesome with the new deal
      break;
    case 'deal.updated':
      console.log('Deal updated:', payload.dealName);
      // Update your local data or trigger some action
      break;
    default:
      console.log('Unhandled event:', event);
  }
  
  res.sendStatus(200);
});

Security Considerations

Don't trust just anyone sending requests to your webhook endpoint. Verify that it's really Salesmate:

const crypto = require('crypto');

app.post('/webhook', (req, res) => {
  const signature = req.headers['x-salesmate-signature'];
  const payload = JSON.stringify(req.body);
  const expectedSignature = crypto
    .createHmac('sha256', 'your-webhook-secret')
    .update(payload)
    .digest('hex');
  
  if (signature !== expectedSignature) {
    return res.sendStatus(403);
  }
  
  // Process the webhook...
});

Replace 'your-webhook-secret' with the secret you set in Salesmate. Safety first!

Testing and Debugging

Salesmate provides a handy webhook testing tool in their dashboard. Use it! It's like a playground for your webhooks. Also, don't forget to log everything during development. You'll thank yourself later.

Best Practices

Handle errors gracefully: Always respond with a 200 status, even if you encounter an error. Handle your errors internally.
Implement retry logic: Sometimes things go wrong. Be prepared to handle failed deliveries.
Be idempotent: Make sure your webhook handler can handle duplicate events without causing issues.

Conclusion

And there you have it! You're now a Salesmate webhook wizard. Remember, with great power comes great responsibility. Use your newfound webhook skills wisely, and may your integrations be ever real-time and your payloads always valid.
