Integrating Real-time Property Data

Step 1: Setting Up Webhooks

First, you need to configure a webhook endpoint in your Fractio API dashboard:

1. Log in to your Fractio API dashboard
2. Navigate to "Settings" > "Webhooks"
3. Click "Add New Webhook"
4. Enter the URL of your endpoint (e.g., https://your-app.com/fractio-webhook)
5. Select the events you want to receive (e.g., "Property Update", "Price Change")
6. Save your webhook configuration

Step 2: Creating a Webhook Endpoint

Now, let's create a simple Express.js server to handle incoming webhook events:

const express = require('express');
const bodyParser = require('body-parser');
const crypto = require('crypto');

const app = express();
app.use(bodyParser.json());

const WEBHOOK_SECRET = 'your_webhook_secret';

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

    if (signature !== expectedSignature) {
        return res.status(403).send('Invalid signature');
    }

    const event = req.body;
    console.log('Received event:', event);

    // Process the event based on its type
    switch (event.type) {
        case 'property.update':
            handlePropertyUpdate(event.data);
            break;
        case 'price.change':
            handlePriceChange(event.data);
            break;
        // Add more event types as needed
    }

    res.sendStatus(200);
});

function handlePropertyUpdate(data) {
    console.log('Property updated:', data.property_id);
    // Update your database or notify your users
}

function handlePriceChange(data) {
    console.log('Price changed for property:', data.property_id);
    console.log('New price:', data.new_price);
    // Update your database or notify your users
}

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

Step 3: Handling Webhook Events

In the code above, we've set up basic handlers for 'property.update' and 'price.change' events. You can expand these handlers to update your database, notify users, or trigger other actions in your application.

Step 4: Testing Your Webhook

To test your webhook:

1. Deploy your webhook server to a publicly accessible URL
2. Update your webhook configuration in the Fractio API dashboard with this URL
3. Use the "Test" button in the dashboard to send a test event
4. Check your server logs to confirm that the event was received and processed correctly

Step 5: Integrating with Your Application

Now that you're receiving real-time updates, you can integrate this data into your application. For example:

• Update your database with the latest property information
• Send notifications to users about price changes or new properties
• Trigger automated actions based on specific events (e.g., update investment recommendations)
