Webhooks

Receive real-time Keycloak events via HTTP POST to your configured endpoints. Webhooks let you integrate authentication events into your own monitoring, analytics, security, or workflow automation systems.

Key Features

• Near real-time delivery: Events are delivered within 3-5 seconds via HTTP POST
• Enriched data: Automatic enrichment with IP geolocation and user-agent parsing
• HMAC-SHA256 signing: Every delivery is signed with a per-webhook secret for payload authenticity
• Flexible filtering: Filter by event type, realm, or cluster
• Inline delivery status: Visual green/red dots show recent delivery health at a glance
• Auto-retry: Failed deliveries are retried with exponential backoff
• Multi-region: Webhooks work across all Skycloak regions (US, CA, EU, AU)

Event Enrichment

Webhook payloads are enriched with additional context that Keycloak does not natively provide:

IP Geolocation

Every event with a client IP address is enriched with geographic data using MaxMind GeoLite2:

{
  "geo": {
    "country": "Canada",
    "country_code": "CA",
    "city": "Toronto",
    "location": { "lat": 43.709, "lon": -79.406 }
  }
}

User-Agent

Browser, operating system, and device information is parsed from the HTTP User-Agent header:

{
  "user_agent": {
    "browser": "Chrome",
    "browser_version": "125.0.0.0",
    "os": "macOS",
    "os_version": "10.15.7",
    "device": "Macintosh",
    "device_type": "desktop",
    "raw": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) ..."
  }
}

Webhook Payload

Each webhook delivery sends a JSON payload with the following structure:

{
  "@timestamp": "2026-04-08T15:30:00.000Z",
  "type": "LOGIN",
  "cluster_id": "9aee835b-79f7-4c40-9aa9-c1d77f885776",
  "workspace_id": "22fc21b0-a15b-4eac-ad9f-d4967f4c59d1",
  "realm_id": "887c7d26-261c-4877-9327-6e96ed81120d",
  "realm_name": "production",
  "client_id": "my-app",
  "user_id": "fe8c0c0b-f1af-4d04-a866-0551f4311308",
  "username": "[email protected]",
  "ip_address": "203.0.113.42",
  "geo": {
    "country": "Canada",
    "country_code": "CA",
    "city": "Toronto",
    "location": { "lat": 43.709, "lon": -79.406 }
  },
  "user_agent": {
    "browser": "Chrome",
    "browser_version": "125.0.0.0",
    "os": "macOS",
    "device_type": "desktop"
  }
}

Admin Events

Admin operation events include additional fields:

{
  "type": "CREATE",
  "operation_type": "CREATE",
  "resource_type": "USER",
  "resource_path": "users/abc-123"
}

Webhook Security

Each webhook is assigned a unique HMAC-SHA256 signing secret. Every delivery includes these headers:

Verifying Signatures

To verify a webhook delivery:

1. Concatenate the timestamp and raw request body: {timestamp}.{body}
2. Compute HMAC-SHA256 using your webhook’s signing secret
3. Compare with the X-Skycloak-Signature header

import hmac
import hashlib

def verify_webhook(body: bytes, timestamp: str, signature: str, secret: str) -> bool:
    message = f"{timestamp}.{body.decode()}"
    expected = hmac.new(secret.encode(), message.encode(), hashlib.sha256).hexdigest()
    return hmac.compare_digest(expected, signature)

Supported Event Types

Authentication Events

• LOGIN / LOGIN_ERROR — User login via browser
• LOGOUT / LOGOUT_ERROR — User logout
• REGISTER / REGISTER_ERROR — New user registration
• CLIENT_LOGIN / CLIENT_LOGIN_ERROR — Service account login
• CODE_TO_TOKEN / CODE_TO_TOKEN_ERROR — Authorization code exchange
• REFRESH_TOKEN / REFRESH_TOKEN_ERROR — Token refresh

User Profile Events

• UPDATE_EMAIL — Email change

Delivery & Retry

• Deliveries that receive a 2xx response are marked as successful
• Failed deliveries are retried with exponential backoff
• After 10 consecutive failures, the webhook is automatically disabled
• Delivery history is visible directly on the webhook card (green/red dots)
• Click the delivery indicator or the history button for full delivery details

Getting Started

1. Navigate to Webhooks in the sidebar
2. Click Create Webhook
3. Provide your HTTP endpoint URL
4. Optionally provide an auth token (sent as Authorization: Bearer header)
5. Select which event types to receive
6. Optionally filter by specific cluster or realm
7. Monitor delivery status directly on the webhook card
