Overview

Integrations and webhooks allow your applications to receive real-time notifications about events in your Scalelite cluster. When servers go offline, meetings start, or alerts trigger, Scalelite sends HTTP POST requests to your configured endpoints.

Key Features:

Real-time HTTP event notifications
HMAC signature verification for security
Automatic retries with exponential backoff
Detailed delivery logs and success tracking

Webhooks Dashboard

Access webhooks from the sidebar under Settings → Integrations. View all configured webhooks, their delivery success rates, and manage endpoints.

🔌 Your Webhooks

Name	URL	Events	Success Rate	Status	Actions

Creating a Webhook

Click Create Webhook button

- Name: Descriptive name (e.g., "Slack Alerts")
- URL: Your HTTP endpoint URL
- Events: Select event types to receive
- Secret: Optional HMAC signing secret
Click Save to create the webhook
Use Test button to send a test payload

Webhook Payload Format

All webhooks receive JSON payloads with this structure:

{
  "event": "alert.created",
  "timestamp": "2024-12-04T10:30:00Z",
  "instance_id": 1,
  "data": {
    "alert_id": 456,
    "severity": "critical",
    "message": "CPU usage exceeded 90%",
    "server_id": 123
  }
}

Security: HMAC Signatures

Verify webhook authenticity using HMAC-SHA256 signatures sent in the X-Webhook-Signature header:

# Python example
import hmac
import hashlib

def verify_signature(payload, signature, secret):
    expected = hmac.new(
        secret.encode(),
        payload.encode(),
        hashlib.sha256
    ).hexdigest()
    return hmac.compare_digest(f"sha256={expected}", signature)

⚠️ Security Tip: Always verify webhook signatures in production to ensure requests are from Scalelite Manager.

Retry Behavior

Failed webhook deliveries are automatically retried with exponential backoff:

Attempt 1: Immediate
Attempt 2: After 1 minute
Attempt 3: After 5 minutes
Attempt 4: After 30 minutes
Attempt 5: After 2 hours (final)

Deliveries are considered failed when:

HTTP status code is not 2xx
Connection timeout (30 seconds)
SSL/TLS errors
