Summary

Receive and verify Zoom webhooks. Use when setting up Zoom webhook handlers, debugging signature verification, completing the endpoint.url_validation handshake, or handling meeting and recording events like meeting.started, meeting.ended, meeting.participant_joined, or recording.

3	## When to Use This Skill
4
5	- How do I receive Zoom webhooks?
6	- How do I verify Zoom webhook signatures?
7	- How do I complete the Zoom `endpoint.url_validation` handshake?
8	- How do I handle `meeting.started`, `meeting.ended`, or `recording.completed` events?
9	- Why is my Zoom webhook signature verification failing?
10
11	## Verification (core)
12
13	Zoom signs each webhook with HMAC-SHA256 (hex) keyed on your app's Secret Token. Build the message `v0:{x-zm-request-timestamp}:{raw body}`, hash it, and prefix with `v0=`. Compare against the `x-zm-signature` header timing-safe. Always use the raw body — parsing to JSON first changes the bytes and breaks the signature.
14
15	Zoom also requires a one-time URL validation handshake: when `event === "endpoint.url_validation"`, respond `200` with `{ plainToken, encryptedToken }` where `encryptedToken = HMAC-SHA256(plainToken, secretToken)` in hex. Respond to every webhook within 3 seconds.
16
17	```javascript
18	const crypto = require('crypto');
19
20	// Verify the x-zm-signature header against v0:{timestamp}:{rawBody}
21	function verifyZoomWebhook(rawBody, timestamp, signature, secretToken) {
22	if (!timestamp \|\| !signature) return false;
23	const message = `v0:${timestamp}:${rawBody}`;
24	const expected = 'v0=' + crypto.createHmac('sha256', secretToken).update(message).digest('hex');
25	try {
26	return crypto.timingSafeEqual(Buffer.from(signature), Buffer.from(expected));
27	} catch {
28	return false;
29	}
30	}
31
32	// Answer the one-time endpoint.url_validation challenge
33	function validationResponse(plainToken, secretToken) {
34	const encryptedToken = crypto.createHmac('sha256', secretToken).update(plainToken).digest('hex');
35	return { plainToken, encryptedToken };
36	}
37	```
38
39	Python:
40
41	```python
42	import hmac, hashlib
43
44	def verify_zoom_webhook(raw_body: bytes, timestamp: str, signature: str, secret_token: str) -> bool:
45	if not timestamp or not signature:
46	return False
47	message = b"v0:" + timestamp.encode() + b":" + raw_body
48	expected = "v0=" + hmac.new(secret_token.encode(), message, hashlib.sha256).hexdigest()
49	return hmac.compare_digest(signature, expected)
50
51	def validation_response(plain_token: str, secret_token: str) -> dict:
52	encrypted = hmac.new(secret_token.encode(), plain_token.encode(), hashlib.sha256).hexdigest()
53	return {"plainToken": plain_token, "encryptedToken": encrypted}
54	```

61	## Common Event Types
62
63	\| Event \| Triggered When \|
64	\|-------\|----------------\|
65	\| `endpoint.url_validation` \| Zoom validates your endpoint (one-time handshake, must be answered) \|
66	\| `meeting.started` \| A meeting starts \|
67	\| `meeting.ended` \| A meeting ends \|
68	\| `meeting.participant_joined` \| A participant joins a meeting \|
69	\| `meeting.participant_left` \| A participant leaves a meeting \|
70	\| `recording.completed` \| A cloud recording finishes processing \|
71
72	> For the full event reference, see [Zoom Webhook Events](https://developers.zoom.us/docs/api/webhooks/).
73
74	## Important Headers
75
76	\| Header \| Description \|
77	\|--------\|-------------\|
78	\| `x-zm-signature` \| Signature `v0=<hex>` over `v0:{timestamp}:{rawBody}` \|
79	\| `x-zm-request-timestamp` \| Unix timestamp included in the signed message \|
80
81	## Environment Variables
82
83	```bash
84	ZOOM_WEBHOOK_SECRET_TOKEN=your_secret_token # From your app's Feature/Webhook page in the Zoom App Marketplace
85	```
86
87	## Local Development
88
89	```bash
90	# Start tunnel (no account needed)
91	npx hookdeck-cli listen 3000 zoom --path /webhooks/zoom
