+# Webhooks Example
+
+![webhook](./webhooks.png)
+
+This example shows how to set up a server to listen for MiroTalk SFU webhook events (join, exitRoom, disconnect).
+
+### Step 1: Enable Webhooks
+
+Edit `app/src/config.js` to enable webhooks:
+
+```javascript
+webhook: {
+    enabled: true, // Enable webhook functionality
+    url: 'http://localhost:8888/webhook-endpoint', // Webhook server URL
+},
+```
+
+---
+
+### Step 2: Run the Webhook Server
+
+1. **Install dependencies**:
+
+    ```bash
+    npm install
+    ```
+
+2. **Start the server**:
+
+    ```bash
+    npm start
+    ```
+
+---
+
+### Step 3: Webhook Events
+
+MiroTalk SFU sends HTTP `POST` requests to the specified URL with event data:
+
+**Example Payload**:
+
+```json
+{
+    "event": "join",
+    "data": {}
+}
+```
+
+- **Events**: `join`, `exit`, `disconnect`.
+- **Data**: Includes `event` and custom `data`.
