3	## When to Use This Skill

5	- Setting up Orb webhook handlers
6	- Debugging Orb signature verification failures
7	- Understanding Orb event types and payloads
8	- Handling usage-based billing, subscription, or invoice events

10	## Verification (core)
11
12	Orb signs every webhook with HMAC-SHA256 over the literal string `v1:{X-Orb-Timestamp}:{rawBody}`. The hex digest is delivered in `X-Orb-Signature` prefixed with `v1=` (e.g. `v1=abc123…`). The ISO 8601 timestamp arrives separately in `X-Orb-Timestamp`. Use the raw request body — don't `JSON.parse` first.
13
14	The `orb-billing` SDK (npm and PyPI) does not expose an `unwrap()`/`constructEvent()` helper at this time, so manual HMAC verification is the canonical path in every framework.

16	Node:

18	```javascript
19	const crypto = require('crypto');
20
21	function verifyOrbSignature(rawBody, signatureHeader, timestamp, secret) {
22	if (!signatureHeader \|\| !timestamp) return false;
23	const provided = signatureHeader.startsWith('v1=') ? signatureHeader.slice(3) : signatureHeader;
24	const expected = crypto
25	.createHmac('sha256', secret)
26	.update(`v1:${timestamp}:${rawBody}`)
27	.digest('hex');
28	try {
29	return crypto.timingSafeEqual(Buffer.from(provided, 'hex'), Buffer.from(expected, 'hex'));
30	} catch {
31	return false;
32	}
33	}
34	```
35
36	Python:
37
38	```python
39	import hmac, hashlib
40
41	def verify_orb_signature(raw_body: bytes, signature_header: str, timestamp: str, secret: str) -> bool:
42	if not signature_header or not timestamp:
43	return False
44	provided = signature_header[3:] if signature_header.startswith("v1=") else signature_header
45	expected = hmac.new(
46	secret.encode(), f"v1:{timestamp}:".encode() + raw_body, hashlib.sha256
47	).hexdigest()
48	return hmac.compare_digest(provided, expected)
49	```

56	## Common Event Types
57
58	\| Event \| Description \|
59	\|-------\|-------------\|
60	\| `customer.created` \| New customer created \|
61	\| `customer.credit_balance_dropped` \| Prepaid credit balance fell below a threshold \|
62	\| `subscription.created` \| New subscription created \|
63	\| `subscription.started` \| Subscription's billing period started \|
64	\| `subscription.ended` \| Subscription ended \|
65	\| `subscription.plan_changed` \| Subscription moved to a different plan \|
66	\| `subscription.usage_exceeded` \| Usage crossed a configured threshold \|
67	\| `invoice.issued` \| Invoice finalized and issued to customer \|
68	\| `invoice.payment_succeeded` \| Invoice paid successfully \|
69	\| `invoice.payment_failed` \| Invoice payment attempt failed \|
70	\| `data_exports.transfer_success` \| Scheduled data export delivered \|
71

74	## Environment Variables
75
76	```bash
77	ORB_WEBHOOK_SECRET=your_webhook_signing_secret # Per-endpoint secret from Orb dashboard
78	```
79
80	The webhook signing secret is configured per webhook endpoint in the Orb dashboard — it is not your account API key.
81
82	## Local Development
83
84	```bash
85	# Start tunnel (no account needed)
86	npx hookdeck-cli listen 3000 orb --path /webhooks/orb
87	```

Orb delivers at-least-once, so consumers should key idempotency on the event `id` field. Key references (open on GitHub):
