Summary

Receive and verify Auth0 webhooks delivered via Custom Log Streams (HTTP). Use when setting up an Auth0 log stream HTTP endpoint, validating the configured Authorization token, or handling batched authentication log events like s (success login), f (failed login), ss (signup), an

1	# Auth0 Webhooks
2
3	Auth0 (by Okta) does not send classic per-event webhooks. Instead you create a
4	Custom Log Stream (HTTP) that batches tenant log events and POSTs them to
5	your endpoint as a JSON array of log records.
6
7	## When to Use This Skill
8
9	- How do I receive Auth0 webhooks / Custom Log Stream events?
10	- How do I secure an Auth0 log stream HTTP endpoint?
11	- How do I validate the Auth0 Authorization token on incoming requests?
12	- How do I handle batched arrays of Auth0 log events?
13	- Why does Auth0 keep retrying my log stream endpoint?
14
15	## Verification (core)
16
17	Auth0 log streams have no HMAC signature. You secure the endpoint with a
18	static shared secret: configure an Authorization header value on the log
19	stream, then compare it against the incoming `Authorization` header on every
20	request using a timing-safe comparison. Always serve the endpoint over
21	HTTPS.
22
23	```javascript
24	const crypto = require('crypto');
25
26	// Compare the incoming Authorization header against the configured token.
27	function verifyAuth0Token(headerValue, expectedToken) {
28	if (!headerValue \|\| !expectedToken) return false;
29	const a = Buffer.from(headerValue);
30	const b = Buffer.from(expectedToken);
31	if (a.length !== b.length) return false; // timingSafeEqual requires equal length
32	return crypto.timingSafeEqual(a, b);
33	}
34	```
35
36	Then process the payload — a JSON array of log records — and return `2xx`
37	quickly. Auth0 retries on any non-2xx response, so acknowledge first and do
38	slow work asynchronously.

44
45	## Common Event Types
46
47	Each record's type is in `event.data.type` (a short log event type code):
48
49	\| Code \| Description \|
50	\|------\|-------------\|
51	\| `s` \| Success Login \|
52	\| `f` \| Failed Login \|
53	\| `ss` \| Success Signup \|
54	\| `fs` \| Failed Signup \|
55	\| `sepft` \| Success Exchange (Password for Access Token) \|
56	\| `seacft` \| Success Exchange (Authorization Code for Access Token) \|
57	\| `feacft` \| Failed Exchange (Authorization Code for Access Token) \|
58	\| `slo` \| Success Logout \|
59
60	> For the full list of codes, see [Auth0 Log Event Type Codes](https://auth0.com/docs/deploy-monitor/logs/log-event-type-codes).

62	## Environment Variables
63
64	```bash
65	# The value you set as the log stream's Authorization header (shared secret).
66	AUTH0_LOG_STREAM_TOKEN=your-long-random-secret
67	```
68
69	## Local Development
70
71	```bash
72	# Start tunnel (no account needed)
73	npx hookdeck-cli listen 3000 auth0 --path /webhooks/auth0
