  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads okta-webhooks automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

The instructions your agent reads when the skill is triggered.

Okta Webhooks

When to Use This Skill

  • Setting up Okta Event Hook handlers
  • Implementing the one-time verification challenge (GET handshake)
  • Authenticating Okta webhook requests with the Authorization header secret
  • Understanding Okta event types and payloads
  • Debugging why Okta event hook verification or delivery is failing

How Okta Event Hooks Differ

Okta Event Hooks do not use an HMAC signature. Security relies on two things:

  1. One-time verification handshake — When you register the hook, Okta sends a GET request with an x-okta-verification-challenge header. You must reply 200 with JSON {"verification": "<challenge value>"}.
  2. Per-request authentication — You choose a secret string that Okta sends in the Authorization header on every event delivery (an HTTPS POST). Verify it with a timing-safe comparison. There is no body signature.

Verification (core)

const crypto = require('crypto');

// 1. One-time verification handshake (GET)
function handleChallenge(req, res) {
  const challenge = req.headers['x-okta-verification-challenge'];
  return res.status(200).json({ verification: challenge });
}

// 2. Per-request auth on every event POST — timing-safe compare of Authorization
function isAuthorized(authHeader, secret) {
  const a = Buffer.from(authHeader || '', 'utf8');
  const b = Buffer.from(secret || '', 'utf8');
  // Length check first: timingSafeEqual throws on unequal-length buffers
  return a.length === b.length && crypto.timingSafeEqual(a, b);
}

Python timing-safe compare: hmac.compare_digest(auth_header, secret).

Common Event Types

Okta event hooks deliver System Log events. Each item in data.events[] has an eventType field:

EventTriggered When
user.lifecycle.createA new user is created
user.lifecycle.activateA user is activated
user.session.startA user signs in to Okta
user.account.lockA user account is locked
user.account.unlockA user account is unlocked
group.user_membership.addA user is added to a group
group.user_membership.removeA user is removed from a group

For the full event catalog, see Okta event types.

Payload Structure

{
  "eventType": "com.okta.event_hook",
  "eventTime": "2026-07-02T12:00:00.000Z",
  "eventId": "b5a4...",
  "data": {
    "events": [
      {
        "uuid": "d6f5...",
        "eventType": "user.session.start",
        "displayMessage": "User login to Okta",
        "published": "2026-07-02T12:00:00.000Z",
        "actor": { "id": "00u...", "type": "User", "alternateId": "jane@example.com" },
        "target": [ { "id": "00u...", "type": "User", "alternateId": "jane@example.com" } ]
      }
    ]
  }
}

The outer eventType is always com.okta.event_hook. The System Log event type you dispatch on lives at data.events[].eventType.
