What is the webhook center?

The Treble webhook center is where you can configure the URLs of your endpoints to receive real-time notifications about relevant platform events. When an event occurs, Treble sends an HTTP POST request to the URL you configure, including a JSON in the body with the event information. Your server can process this information to execute specific actions such as updating records, sending alerts, or initiating internal processes.

​
Available event types

Currently, you can subscribe to different types of global events:
  • HSM Status Update: Notifies when an HSM changes state.
  • Session Close Update: Notifies when a conversation session is closed.
  • Deployment Failure: Notifies when an error occurs during a deployment.
Each of these webhooks can be activated or deactivated according to your needs from the configuration panel.

​
Requirements

  • Your endpoint must respond in less than 5 seconds.
  • The response must be a valid JSON body.
  • It’s recommended to use HTTPS for greater security.

​
Basic example

Here’s an example in Node.js to handle a Treble webhook: 
const express = require('express');
const app = express();
app.use(express.json());

app.post('/webhook', (req, res) => {
  const { event_type } = req.body;

  console.log('Event received:', event_type);

  // Process the event according to its type
  switch (event_type) {
    case 'hsm.status':
      // Logic to handle HSM state changes
      break;
    case 'session.close':
      // Logic to handle session closure
      break;
    case 'deployment.failure':
      // Logic to handle deployment failures
      break;
  }

  res.status(200).json({ success: true });
});

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