Auth0 webhook setup with Webhookify

Auth0 is the leading identity and access management platform, providing authentication and authorization services for over 14,000 organizations worldwide. Every login attempt, signup, password change, and MFA challenge generates security events that engineering and security teams must monitor. While Auth0 provides a log viewer in the dashboard and can stream logs to SIEM tools, many teams need instant alerts for critical authentication events delivered to their existing communication channels. Webhookify transforms Auth0 authentication events into instant, AI-summarized notifications delivered to Telegram, Discord, Slack, Email, or your mobile device, giving you real-time security visibility without constantly checking the Auth0 dashboard.

This guide walks you through connecting Auth0 log streaming to Webhookify step by step. Whether you need to monitor security threats, track user signups, or audit authentication activity, you will be set up in under 15 minutes.

Why Monitor Auth0 Events with Webhookify?

  • Security Threat Detection: Get instant alerts when suspicious authentication events occur. Failed login spikes, brute force protection triggers, and anomalous login locations are delivered to your phone immediately, enabling rapid response to potential security incidents.

  • User Signup Tracking: Monitor new user registrations in real time. Product teams can track growth, identify registration surges from marketing campaigns, and detect bot signup patterns before they impact your user metrics.

  • MFA Monitoring: Track MFA enrollment and challenge events. Know when users are prompted for multi-factor authentication, when they succeed or fail, and when MFA policies are triggered. This helps security teams assess their MFA adoption rates and identify users who may need support.

  • Compliance Auditing: Many regulations (SOC 2, HIPAA, GDPR) require real-time monitoring of authentication events. Webhookify provides an additional notification layer on top of Auth0's logging, ensuring your team is immediately aware of security-relevant events.

  • AI-Powered Context: Instead of raw log event codes, Webhookify uses AI to generate human-readable summaries. A failed login event becomes "Failed login attempt for user john@example.com from IP 203.0.113.45 (San Francisco, US) -- invalid password, 3rd failed attempt in 10 minutes" rather than a cryptic event type code.

Prerequisites

  1. An Auth0 account with access to the Dashboard (Essential plan or higher for Log Streaming)
  2. A Webhookify account (sign up free at webhookify.app)
  3. At least one notification channel configured in Webhookify (Telegram, Discord, Slack, Email, or mobile push)
  4. Auth0 Dashboard Admin or higher permissions to configure log streams

Step-by-Step Setup Guide

1

Create a Webhookify Endpoint

Log into your Webhookify dashboard at webhookify.app. Click "Create Endpoint" to generate a unique webhook URL:

https://hook.webhookify.app/wh/a0_ghi789jkl012

Copy this URL. Name the endpoint descriptively, such as "Auth0 - Security Events" or "Auth0 - User Activity." For security-focused monitoring, consider creating separate endpoints: one for critical security events (failed logins, brute force) routed to high-priority channels, and another for general activity (signups, password changes) routed to standard channels.

2

Configure Your Notification Channel

Set up your preferred notification channels in the Webhookify settings before connecting Auth0.

For Telegram: Connect the Webhookify bot and select a chat or group. Security teams often create a dedicated "Auth Security Alerts" group for authentication monitoring.

For Discord: Authorize the bot and choose a channel like #auth-alerts or #security-monitoring in your Discord server.

For Slack: Complete the OAuth flow and select a channel. Teams commonly use channels like #auth0-alerts, #security-events, or #user-signups.

For Email: Add individual or security team email addresses. This creates a searchable audit trail of all authentication events, valuable for compliance reporting.

For Mobile Push: Install the Webhookify app on your phone, sign in, and enable push notifications. This is critical for security teams that need to respond to brute force attacks, account takeover attempts, and other threats immediately.

Configure Log Streaming in Auth0

Navigate to the Auth0 Dashboard:

  1. Go to Monitoring > Streams in the left sidebar
  2. Click "Create Log Stream"
  3. Select "Custom Webhook" from the available stream types
  4. Configure the stream:
  • Name: Give it a descriptive name like "Webhookify Security Alerts"
  • Payload URL: Paste your Webhookify endpoint URL
  • Content Type: Select application/json
  • Content Format: Select JSON Array (Auth0 sends events in batches)
  • Authorization Token: (Optional) Add a bearer token for additional security. Webhookify logs all headers including the Authorization header for verification.
  1. Click "Save"

Auth0 will begin streaming log events to your Webhookify endpoint. Events are delivered in near real-time, typically within a few seconds of occurring.

Select Events to Monitor

Auth0 log streaming sends all events by default. You can filter events using Event Filters in the stream configuration. Auth0 uses event type codes to categorize events. The most security-relevant events are:

Successful Authentication:

  • s -- Successful login
  • ss -- Successful signup
  • sv -- Successful email verification
  • scp -- Successful password change

Failed Authentication:

  • f -- Failed login
  • fp -- Failed login (incorrect password)
  • fu -- Failed login (invalid email/username)
  • fs -- Failed signup
  • fcp -- Failed password change

Security Events:

  • limit_wc -- Brute force protection triggered (too many login attempts)
  • limit_mu -- Blocked IP address
  • limit_ui -- Too many signups from same IP
  • cls -- Code/Link sent (passwordless login)
  • gd_start_enroll -- MFA enrollment started
  • gd_auth_succeed -- MFA challenge succeeded
  • gd_auth_failed -- MFA challenge failed

Account Events:

  • sapi -- API operation (user management via Management API)
  • ublkdu -- User account unblocked
  • du -- User deleted

To filter for only critical security events, configure the event filter in your Auth0 stream settings to include event types like f, fp, fu, limit_wc, limit_mu, gd_auth_failed, and du.

For user growth tracking, include ss (successful signup) and s (successful login) events.

Test Your Configuration

After creating the log stream, test the connection by triggering authentication events:

Testing login events:

  1. Open your application that uses Auth0 for authentication
  2. Log in with valid credentials
  3. Check your Webhookify dashboard for the s (successful login) event
  4. Verify the notification arrived on your configured channel

Testing failed login events:

  1. Attempt to log in with an incorrect password
  2. Check for the fp (failed password) event in the Webhookify dashboard

Testing signup events:

  1. Create a new account through your application's signup flow
  2. Check for the ss (successful signup) event

Auth0 log streaming may have a brief delay (5-30 seconds) for the first event as the stream initializes. Subsequent events should arrive within a few seconds.

If events appear in the Webhookify dashboard but notifications are not delivered, check your notification channel configuration. If no events appear, verify the stream status in Auth0 Dashboard > Monitoring > Streams and ensure it shows as "Active."

Real-World Use Cases

  • Brute Force Detection and Response: A fintech company monitors limit_wc (brute force protection) and fp (failed password) events through a high-priority Telegram channel with mobile push notifications. When Auth0's brute force protection triggers, the security engineer receives an instant alert with the target email, source IP, and number of failed attempts. They can immediately investigate and block the IP or lock the account if needed, reducing mean time to response from hours to under 2 minutes.

  • User Growth Dashboard: A SaaS startup routes ss (successful signup) events to a shared Slack channel visible to the entire company. Each new signup triggers an AI-summarized notification showing the user's email, signup method (social login, email/password), and IP location. The team celebrates signups in real time and can correlate growth spikes with marketing activities. The mobile push notifications even play a satisfying sound for each new user.

  • MFA Adoption Monitoring: A healthcare platform required to comply with HIPAA monitors gd_start_enroll and gd_auth_succeed events. The security team tracks MFA enrollment rates in real time through a Discord channel. When they notice enrollment numbers plateau, they launch targeted campaigns to encourage adoption. Failed MFA challenges (gd_auth_failed) trigger immediate security reviews.

  • Suspicious Login Alerting: An e-commerce platform monitors successful login events (s) and uses Auth0's anomaly detection. When a login occurs from an unusual location or device, Auth0 generates specific event types that Webhookify forwards as high-priority alerts. The security team reviews these alerts within minutes and can force password resets or session invalidation for compromised accounts.

Example Notification

Here is what a typical Webhookify notification looks like for an Auth0 brute force protection event:

New Webhook Event Received

Source: Auth0
Event: limit_wc (Brute Force Protection)
Endpoint: Auth0 - Security Events

AI Summary:
Brute force protection triggered:
  Target: john.smith@example.com
  Source IP: 203.0.113.45 (São Paulo, Brazil)
  Failed Attempts: 10 in the last 5 minutes
  Action: Account temporarily blocked
  Client: My Web Application
  Connection: Username-Password-Authentication
  User Agent: Mozilla/5.0 (Windows NT 10.0)

This IP has not been seen before for this account.

Troubleshooting

  1. Log stream shows "Paused" status: Auth0 automatically pauses log streams that consistently fail to deliver events. Check that your Webhookify endpoint URL is correct and accessible. Re-activate the stream by clicking "Resume" in the Auth0 Dashboard > Monitoring > Streams page.

  2. Events are delayed by several minutes: Auth0 log streaming processes events in near real-time but may batch them during high-volume periods. A delay of 5-30 seconds is normal. If delays exceed several minutes, check the Auth0 status page (status.auth0.com) for any ongoing platform issues.

  3. Too many events overwhelming notifications: Auth0 generates many event types, and busy applications can produce thousands of events per hour. Use Auth0's event filters on the stream configuration to limit which event types are forwarded. Focus on security-critical events like failed logins, brute force triggers, and account changes. Save routine login events for your SIEM tool instead.

  4. Event type codes are cryptic: Auth0 uses short event type codes (like s, f, fp, limit_wc) rather than human-readable event names. Webhookify's AI summary translates these into understandable descriptions. You can also reference the Auth0 Log Event Type Codes documentation for a full mapping of codes to descriptions.

  5. Webhook receiving duplicate events: Auth0 log streaming uses at-least-once delivery, which means the same event may occasionally be delivered more than once. Webhookify logs each delivery separately. Use the log_id field in the event payload to deduplicate if needed for downstream processing.

For the strongest security monitoring setup, create two Webhookify endpoints: one for security-critical events (failed logins, brute force, account blocks) routed to a high-priority channel with mobile push notifications and the cash sound disabled, and another for growth events (signups, email verifications) routed to a team-wide Slack channel. Filter the security endpoint to only include event types f, fp, fu, limit_wc, limit_mu, gd_auth_failed, and du. This separation ensures security threats get immediate human attention while growth metrics remain informational.
