# Webhook Integration

### Overview <a href="#overview" id="overview"></a>

Webhooks allow AINexLayer to send real-time notifications to your applications when specific events occur. This enables you to build automated workflows, integrate with external systems, and respond to platform events in real-time.

### Webhook Concepts <a href="#webhook-concepts" id="webhook-concepts"></a>

#### What are Webhooks? <a href="#what-are-webhooks" id="what-are-webhooks"></a>

* **Event-Driven**: Triggered by specific events in AINexLayer
* **Real-Time**: Immediate notification when events occur
* **HTTP POST**: Send data to your application endpoint
* **Retry Logic**: Automatic retry for failed deliveries
* **Security**: Signed payloads for verification

#### Webhook Flow <a href="#webhook-flow" id="webhook-flow"></a>

1. **Event Occurs**: User action triggers an event
2. **Webhook Triggered**: AINexLayer identifies registered webhooks
3. **HTTP Request**: POST request sent to your endpoint
4. **Response Required**: Your endpoint must respond with 2xx status
5. **Retry on Failure**: Failed deliveries are retried automatically

### Supported Events <a href="#supported-events" id="supported-events"></a>

#### Document Events <a href="#document-events" id="document-events"></a>

* `document.uploaded` - Document uploaded to workspace
* `document.processed` - Document processing completed
* `document.failed` - Document processing failed
* `document.deleted` - Document deleted from workspace
* `document.updated` - Document metadata updated

#### Chat Events <a href="#chat-events" id="chat-events"></a>

* `chat.message` - New chat message sent
* `chat.conversation.started` - New conversation started
* `chat.conversation.ended` - Conversation ended
* `chat.response.generated` - AI response generated

#### Workspace Events <a href="#workspace-events" id="workspace-events"></a>

* `workspace.created` - New workspace created
* `workspace.updated` - Workspace settings updated
* `workspace.deleted` - Workspace deleted
* `workspace.user.added` - User added to workspace
* `workspace.user.removed` - User removed from workspace

#### User Events <a href="#user-events" id="user-events"></a>

* `user.created` - New user registered
* `user.updated` - User profile updated
* `user.deleted` - User account deleted
* `user.login` - User logged in
* `user.logout` - User logged out

### Webhook Configuration <a href="#webhook-configuration" id="webhook-configuration"></a>

#### Create Webhook <a href="#create-webhook" id="create-webhook"></a>

**Request Body:**

**Response:**

**Query Parameters:**

* `page` (optional): Page number
* `limit` (optional): Items per page
* `active` (optional): Filter by active status

#### Signature Verification <a href="#signature-verification" id="signature-verification"></a>

AINexLayer signs webhook payloads using HMAC-SHA256. Verify the signature to ensure the webhook is from AINexLayer.

### Webhook Implementation <a href="#webhook-implementation" id="webhook-implementation"></a>

#### Webhook Delivery Logs <a href="#webhook-delivery-logs" id="webhook-delivery-logs"></a>

**Query Parameters:**

* `page` (optional): Page number
* `limit` (optional): Items per page
* `status` (optional): Filter by delivery status

### Best Practices <a href="#best-practices" id="best-practices"></a>

#### Webhook Endpoint Design <a href="#webhook-endpoint-design" id="webhook-endpoint-design"></a>

* **Idempotency**: Handle duplicate webhook deliveries
* **Timeout**: Respond within 30 seconds
* **Status Codes**: Return appropriate HTTP status codes
* **Logging**: Log all webhook events for debugging
* **Error Handling**: Handle errors gracefully

#### Security <a href="#security" id="security"></a>

* **Signature Verification**: Always verify webhook signatures
* **HTTPS**: Use HTTPS for webhook endpoints
* **Secret Management**: Store webhook secrets securely
* **Rate Limiting**: Implement rate limiting on webhook endpoints
* **Access Control**: Restrict access to webhook endpoints

#### Performance <a href="#performance" id="performance"></a>

* **Async Processing**: Process webhooks asynchronously
* **Queue System**: Use message queues for high-volume webhooks
* **Monitoring**: Monitor webhook delivery success rates
* **Retry Logic**: Implement retry logic for failed processing
* **Scaling**: Scale webhook processing based on load

### Troubleshooting <a href="#troubleshooting" id="troubleshooting"></a>

#### Common Issues <a href="#common-issues" id="common-issues"></a>

**Webhook Not Receiving Events**

* Check webhook URL is accessible
* Verify webhook is active
* Check event subscriptions
* Review webhook delivery logs

**Signature Verification Fails**

* Verify webhook secret is correct
* Check payload format
* Ensure signature header is present
* Review signature generation logic

**Webhook Timeouts**

* Optimize webhook processing
* Increase timeout settings
* Use async processing
* Monitor response times

#### Debugging Tools <a href="#debugging-tools" id="debugging-tools"></a>

* **Delivery Logs**: Review webhook delivery logs
* **Test Endpoint**: Use test endpoint to verify webhook
* **Signature Verification**: Test signature verification
* **Event Filtering**: Check event subscriptions
